1. What’s New
AssuredSAN 4xx4
4xx4 Controllers
Dot Hill AssuredSAN™ 4004 storage arrays offer greater data security, faster throughput and substantial
business benefits for markets that demand extremely high-bandwidth performance, such as cloud service
providers, media & entertainment, oil & gas, telecommunications, big data analytics and digital image
archiving. Host interface options include 12Gb SAS, 8Gb and 16Gb FC, 1Gb and 10Gb iSCSI and the only
hybrid 16Gb Gen 5 Fibre Channel/10Gb iSCSI converged interface.
The AssuredSAN 4004 solutions are built on the company's ninth-generation RAID stack, which delivers up to
100,000 input/output operations per second (IOPS) from disk, sustained sequential read performance of up to
6400 MB/second and writes of up to 5300 MB/second. The Dot Hill RAID Companion Processor (RCP) allows
4004 solutions to deliver dramatic performance gains at very aggressive price points. AssuredSAN 4004
solutions also integrate all the performance tuning and optimizations of the previous-generation AssuredSAN
4000 models, which includes streaming performance optimization to handle randomized, sequential workloads.
Dot Hill's latest firmware utilizes a proprietary Adaptive Read-ahead Algorithm that analyzes workloads and
fine tunes options to optimize the performance of specific kinds of demanding workloads, delivering better
response times and meeting IT service level agreements.
RealStor Software:
RealStor™ 2.0, delivers application-aware intelligence for today’s next-generation hybrid flash storage arrays.
Easy-to-use RealStor 2.0 accelerates storage management operations to deliver data where customers need it,
when they need it. With patent-pending innovations that deliver better efficiency, higher reliability and costeffectiveness, fast access to critical “hot” data, RealStor 2.0 is now available across Dot Hill’s entire line of
storage systems equipped with AssuredSAN 4004 storage controllers.
Ultra48 AssuredSAN 4004:
Dot Hill AssuredSAN 4004 Ultra48 high-density storage arrays use a unique chassis design that was designed
internally to maximize storage processing power in a minimal footprint for greater data center efficiency. The
first of its kind in the industry, the Dot Hill high-density chassis houses up to 57 terabytes of data on small form
factor 2.5-inch drives, in a 2U footprint. All Dot Hill AssuredSAN Ultra48 models are built on the company’s
ninth-generation RAID stack, which delivers up to 20 percent faster sequential read workloads and up to 70
percent faster sequential writes, compared to previous-generation products. Like previous generation Dot Hill
products, the next generation will deliver 99.999 percent data availability, assuring organizations of round-theclock access to data.
Ultra56 AsuredSAN 4004:
Dot Hill Ultra56™ AssuredSAN®, a new hybrid flash storage array based on an ultra-density chassis that
supports both NEBS Level 3 carrier and MIL-STD government requirements and up to 1.34 petabytes (PB) of
capacity. The Ultra56 AssuredSAN includes the same dual active, redundant 4004 controllers as other Dot Hill
storage arrays, affording up to 6400MB/sec of sustained read performance and complete meta-data
compatibility within the Dot Hill family of storage solutions. It is the only high density storage product on the
market today that meets the extremely demanding requirements of telecommunications carriers, service
providers and tactically deployed government installations.

3.1.1. Shipping Notes:
SFPs:
Each 4-pack will ship in a separate box
When ordering a part (PFRUKK14) you only order quantity of 1 – you will receive 4 SFPs.
Drives: When ordering bulk packs ending in 14 or 24, order the exact # of drives that are needed.
So ordering 22 x (PFRUKFXAXN161-24 / DD,SV3,900GB,10K,6G,SAS,BB,Bulk) = 22 x 900G drives.
For Low density chassis 2U12 and 2U24 - drives ship in the chassis
For High density chassis 2U48 and 4U56 - drives ship in separate cartons from the chassis

4.1.Protocols – CNC (FC&iSCSI) & SAS (Hybrid)
AssuredSAN 4xx4 controller architecture maximizes performance, including
Four host ports per controller
 48x4 controller supports 8Gb FC, 16Gb FC, 1GbE iSCSI or 10GbE iSCSI SFPs.
 45x4 SAS controller supports 6Gb and 12Gb SAS host connectivity using mini-SAS HD Cables.
4 GB transportable read/write cache per controller.

Single Controllers:
Single controllers are supported in the 2U12, 2U24, 2U48, and 4U56 but NOT recommended due to
lack of failover capability.

Hybrid Connectivity:
4xx4 Controller allows customers to create their own Hybrid Controller by mixing FC and iSCSI SFPs.
To run in hybrid connectivity, ports 0&1 are required to be FC, ports 2&3 are required to be iSCSI. Using mixed
speeds, such as a 16G FC SFP and an 8G FC SFP is not supported.
Port matrix:
Port 0,1,2,3 = All FC or
Port 0,1,2,3 = All iSCSI
Port 0,1 = FC + Port 2,3 = iSCSI

4.2.SFPs
For CNC versions (D48xxx), two sets of four-packs are advised. Both FC and iSCSI transceivers contain
unique identification preventing unqualified SFP’s from being used in the 4xx4 (LX) controller.
Dot Hill branded SFP's must be ordered with the AssuredSAN 4xx4 controllers with the CNC (Converged
Network Controller). They are available in 4 packs, so quantity 2 is recommended. They are available in
1G iSCSI, 10G iSCSI, 8G FC, or 16G FC. SAS and JBOD systems do not require SFP's.
TLAs for the SFPs for the 2U12, 2U24, 2U48, and 4U56 are below.

4.3.Firmware
As of February 1, 2015:
 2U12, 2U24, and 2U48 – GL200 firmware is included with new shipments
 4U56 – GL205 is included with new shipments.
If, and only if, a 4U56 (Ultra56) is part of your configuration – GL205 firmware must be present in the
RBOD – regardless of which chassis has the RBOD.
GL205 is not intended to be an upgrade firmware – only to provide Ultra56 functionality.
In general, for customers who have already purchased a 4xx4, the following firmware is needed for the
respective functionality.

GL210 is expected shortly and is intended to be upgrade firmware that will provide the above functionality
and for all chassis. Upgrade: to download the latest firmware, go to CRC.Dothill.com
4.4.RAID Levels Supported
The 4xx4 controller supports RAID 0, 1, 3, 5, 6, 10, 50
In addition to the usual RAID levels, the 4xx4 features several important additional levels. RAID 6 offers the
highest level of RAID protection. It allocates two sets of parity data across drives and allows simultaneous
write operations. It can withstand two simultaneous drive failures without downtime or data loss. RAID 10 is
mirroring and striping without parity and allows large Disk Groups to be created with high performance and
mirroring for fault tolerance. RAID 50 combines the block striping and parity of RAID 5 with the straight
block striping of RAID 0, yielding higher performance than RAID 5 through the addition of RAID 0,
particularly during writes.

5. Chassis:
The AssuredSAN 4xx4 storage arrays are powerful RAID data storage solutions which can scale to hundreds
of terabytes of storage with additional expansion arrays. Our dual redundant design eliminates ‘single points
of failure’ which can disrupt business operations. AssuredSAN arrays have dual active-active controllers for
higher performance and failover, ‘hot swappable’ drives, dual power supplies and fans, all of which
contribute to proven 99.999% uptime.

5.6.2. Ultra56
The minimum number of HDDs supported is14 and a maximum number of drives are 240. When loading
a chassis that is not full, drives are to be loaded left to right, then front to back - in increments of 14 drives.

If an Ultra56 is loaded full of drives, the order does not matter. Drives are loaded from the top

If an Ultra56 is loaded partially full, drives must be installed in groups of 14. Loading
recommendation is left to right, front to back. Based on prescribed slot assignment shown above,
load slots 0-6, then 28-34, then 7-13, then 35-41, then 14-20, then 42-46, than 21-27, then 49-56.
5.7.Hot Plug Expansion & Replacement Support
All 4xx4 models support hot plug expansion and replacement of redundant controllers, enclosures, fans,

6. Expansion JBODs
6.1.Expansion JBOD Overview
Just as the user has a choice of chassis for the array head (LFF and SFF drive bays, AC or DC powered), so
also do they have a choice of expansion disk enclosures accommodating either drive size. The J6G12, J6G24,
J6G48, and J6G56 can be hot-added to an operating array. SFF and LFF Array RBODs and JBODs are
mixed with few limitations.
J6G12, 3.5-inch Disk Enclosure. This 2U unit has twelve LFF (3.5-inch) drive bays and accepts dual-ported
SAS, SEDs and SAS MDL drives. The pre-configured LFF Drive Enclosures has two I/O modules and
supports both single and dual controller arrays.

7.4.Encryption (SED/FDE)
AssuredSAN 4xx4 supports Self-Encrypting Drives (SED) or Full Drive Encryptions (FDE) to allow customers to
secure their critical data and comply with all required regulatory mandates. Note: Both FDE and SED are
encryption drives (same meaning) – different names are sometimes used due to different suppliers.




All drives within the array must be self-encrypted drives to enable the encryption feature. There cannot
be a mixture of encrypted and non-encrypted drives within the same array.
SEDs can be used in a non-SED environment, but will not be encrypted unless all drives in the array are
SED
Self-encrypted drives are only supported on the AssuredSAN 4xx4 Storage array and requires Firmware
version GL105 or later. Customers must upgrade their controller firmware to GL105 or later for SelfEncrypting Drive functionality.
All SEDs are FIPS 140-2 compliant FIPS 140-2 Validated Self-Encrypting Drives (SEDs) have been
certified by the U.S. National Institute of Standards and Technology (NIST) and Canadian
Communications Security Establishment (CSE) as meeting the Level 2 security requirements for
cryptographic modules as defined in the Federal Information Processing Standards (FIPS) 140-2

7.5.512e Drives
For AssuredSAN storage arrays, Dot Hill supports emulation, or 512e drives, rather than the 4K native
sector format for the drives. 512e drives will start to ship in 2015 under the same part #’s (TLAs) as ship
today. These drives include emulation (e) which supports backward compatibility for the many
applications and legacy operating systems that do not support 4K native drives. Dot Hill continues to
work actively with its drive suppliers and firmware teams to optimize drives to reduce the potential
performance impacts that come with emulation and enable your organization to gain greater value from
512e drives.
Older versions of application software such as virtualization software that reside between the operating
system and your storage firmware may not fully support 512e drive emulation. If not, performance
degradation might result. Please ensure that you have upgraded to the most recent version of any
software that might be affected, and refer to its documentation for further information.

8.2.RealStor
RealStor gives users access to several new key features including Autonomic-tiering, thin provisioning, SSD
read cache, storage pooling, and several other important features. The new features will be accessed via a
new User Interface, referred to as V3. This new management GUI brings a new modern look and feel to
array management. Existing customers can choose to use the new V3 or to continue to use the previous
generation V2 if new virtualization features are not required.
8.2.1. New User Interface:
RealStor 2.0 introduces advanced storage software for hybrid arrays, built for easy to use storage management,
and optimizing performance and capacity needs in Real-Time to address today’s dynamically
changing workloads. The new .v3 Storage Management Console for RealStor 2.0 provides all the capabilities
of the prior interface with an updated look and feel that scales well for managing lar ge numbers of volumes
and hosts. New systems default to the new .v3 interface.
Page | 26
Config Guide
AssuredSAN 4xx4
v3: Specifies to use the new WBI interface to manage virtual and linear storage, and to use terminology in
CLI output and system messages that is oriented to managing a hybrid (linear and virtual) system, such as
“disk group” for disk groups and “pool” for pools. This is the default for a new installation.
8.3.Storage Pools/Virtual Disk Groups/Volumes:
Storage Pools allow data on a given LUN to span across all drives in a pool. When capacity is added to a
system, the user is also getting a performance benefit of the additional spindles –hence the term Wide
Striping. Storage Pools are available with GL200 firmware or newer.
Virtual Disk Groups
When creating a Virtual Disk Group, the user can specify the RAID level (RAID 1, 5, 6, 10) and which Pool
the Disk Group belongs to. Disk Groups must contain like disk types: SSD, Enterprise SAS, MDL SAS.
The user must select a valid group of available HDDs or SSDs for the chosen RAID type. These
configuration rules are the same as creating a VDisk with the prior V2 interface. Unlike creating VDisks in
the V2 SMU, the chunk size is automatically set to 512KB and does not need to be modified by the user. An
example of the V3 Add Disk Group Screen is shown below:
Volumes in Virtual Disk Pools:
To further explain the virtual disk pool concept, we will first look at how volumes are treated in the virtual
disk pool. One of the key concepts of the RealStor 2.0 firmware is the addition of a virtualization layer which
allows a volume’s data to be segmented into discrete 4MB entities called pages. These 4MB pages are
managed individually, and can allow a volume’s data to be spread over potentially multiple underlying
storage pool Virtual Disk Groups and potentially multiple tiers (SSD, Enterprise SAS, MDL SAS) of disks.
8.3.1. Mapping in the V3 Interface:
Once the users have added their Disk Groups to create the Pools, they may now create and map volumes.
This is very similar to how the customers currently create volumes in GL105 firmware, however volumes are
now assigned to a pool instead of a VDisk.
RealStor 2.0 includes the ability to assign volumes to groups. This grouping capability enables large numbers
of initiators to be mapped to LUNs in a single operation – improving the efficiency and organization of host
configuration. In addition, the V3 SMU incorporates search filters that greatly simplify the task of managing
large numbers of volumes and reduce management time.
To map a volume, the user may select the Mapping topic, or click on the volume and select Mapping under
the action tab. The Mapping screen in the V3 interface is different than the V2 version and contains several
enhancements.
Page | 27
Config Guide
AssuredSAN 4xx4
Users may now create initiator names, assign to Hosts, and then assign Host to Host Groups. This greatly
simplifies the tasks of managing and mapping large numbers of Hosts that may have the same mapping
requirements. Filter capabilities also exist for the Host and Host group tables.
RealStor 2.0 allows for users to do default mapping by selecting “All other initiators.” Selecting this will
make the volume available to all host ports. The user may also do explicit mapping - mapping to individual
initiators, hosts, or host groups. The Storage Management Console will map to both the A and B controller
by default for each port. Figure 5 is an example of the Mapping Screen.
8.3.2. Provisioning and Mapping with the CLI Interface:
RealStor 2.0 will support a robust CLI interface. RealStor 2.0 maintains a set of commands for the Linear
(V2) interface, and a separate set of commands specific to the new virtual (V3) interface. While much of the
command-set is shared between the two, there are some significant differences which are required to maintain
backwards compatibility while allowing users to manage both versions in the same CLI.
While this document is not intended to highlight all the differences, some of the commands specific to
provisioning and mapping that customers will want to review are highlighted here. For detailed description of
all the changes, CLI Reference guide will be available.
First, specific to setting a management interface, Set protocols and set cli-parameters will include support
for setting the management-mode interface to v2 or v3 at both a global (set protocols) or session level (set
cli-parameters). This setting will dictate which CLI commands are used.
With the introduction of the term disk group, RealStor 2.0 will provide a new set of CLI commands to
configure disk groups: add disk-group, remove disk-groups, show disk-groups, etc. Disk groups are a
group of disks that together form a RAID set.
In a V2 (RAIDar 2.0) environment, disk groups are exactly the same as vdisks. Commands used to manage
vdisks in GL105 code will be the same as in the V2 interface.
With volumes now residing in pools, a new set of CLI commands is available to manage them; show pool,
remove pool, etc.
As highlighted above, the CLI will allow supporting for host groups in both the V2 and V3 interface modes.
However, the term host can have a different meaning depending on whether you are grouping, or using the
legacy context of the command. RealStor 2.0 will also introduce volume groups for virtual volumes. For
additional information regarding CLI command changes, please refer to the CLI Reference Guide for a more
detailed description.
8.4.Thin Provisioning:
Thin Provisioning allows storage allocation of physical storage resources only once they are consumed by
an application. Thin Provisioning also allows over-provisioning of physical storage pool resources allowing
ease of growth for volumes without predicting storage capacity upfront. Thin Provisioning is available with
GL200 firmware or newer.
Thin Provisioning and Modern File Systems
Many modern operating systems become automatically aware of an array's ability to support thin provisioning.
This is true of Windows 2012 / 2012 R2 and Linux with newer 6.x kernels. When using a non -thin provisioned
storage array the deletion of a file does nothing more than rearrange the file system pointers.
If the array supports thin provisioning, as with RealStor 2.0, thin-aware operating systems will notify the
storage array to free the storage that had been allocated to the file that was deleted. Thi s happens with the SCSI
UNMAP command. This will allow for the re-use of the capacity that had been allocated for the deleted file.
Page | 28
Config Guide
AssuredSAN 4xx4
Windows 2012 / 2012 R2 also issues notifications when the allocations reach a high percentage of the
"advertised" capacity. This, along with the capacity usage notifications, signals the user that it may be time to
add more physical storage.
How do I Enable Storage Over-Commitment With RealStor?
Overcommit is a pool setting (default on). When enabled, the aggregate capacity of a volume can exceed the
physical backing storage.
The user can create a volume on a pool with over-commitment Enabled, no configuration needs to be done to
create such a volume. Figure 3 shows that a volume can be logically larger than the pool that it’s assigned to.
Figure 3 – Volume that is logically larger than the pool
Note: If you try to disable overcommit and the total space allocated to thin-provisioned volumes exceeds the
physical capacity of their storage pool, an error will say that there is insufficient free disk space to complete
the operation and overcommit will remain enabled.



8.5.
Thresholds and Notifications
Users with a manage role can view and change settings that affect the thresholds and corresponding
notifications for each storage pool.
Low Threshold – When this percentage of pool capacity has been used, Informational event 462 is generated
to notify the administrator. Thus value must be less than the Mid Threshold value. The default is 25%.
Mid Threshold – When this percentage of pool capacity has been used, event 462 is generated to notify the
administrator to add capacity to the pool. This value must be between the Low Threshold and High
Threshold values. The default is 50%. If the commitment setting is enabled, the event has Informational
severity; if the over-commitment setting is disabled, the event has Warning severity.
High Threshold – When this percentage of pool capacity has been used, Critical event 462 is generated to
alert the administrator that it is critical to add capacity to the pool. This value is automatically calculated
based on the available capacity of the pool minus reserved space.
Performance Volumes LUNs and Rapid Rebuilds:
8.5.1. Large LUNs:
The RealStor 2.0 firmware release introduces the concept of Virtual Disk Pools – which are comprised of
multiple Virtual Disk Groups (a disk group is similar to a VDisk). This now decouples the LUN from being
restricted to a single VDisk. A Volume’s data on a given LUN can now expand across all disk drives in a
pool. When capacity is added to a system, the user is also getting a performance benefit of the additional
spindles –hence the term Performance Volume.

General “Best Practice” for VMFS datastores is to use large LUNs for use by multiple VMs. Large LUNs
gives VMware vSphere users the most flexibility by not requiring storage administrators to provision new
storage every time a new VM is created. Large LUNs also minimize rescans for new LUNs on the ESX
server, which can impact VMFS I/O.
Operating Systems now support up to 16TB file systems.
As enterprise workloads for virtual environments grow in size and in performance demands, virtual hard disk
(VHD) formats need to accommodate them. Hyper-V in Windows Server 2012 introduces a new version of
the VHD format called VHDX which supports virtual disks up to 64TB in size.
The RealStor 2.0 supports large, flexible Volumes with sizes up to 128TB spanning up to 256 HDDs
(architectural limit) providing seamless capacity expansion. Data automatically reflows to new drives and
IOPs scales with additional storage.
8.5.2. Rapid Rebuilds:
Rebuild of conventional (Linear) storage requires that the entire VDisk is rebuilt prior to returning the VDisk
(and thus the Volumes on the VDisk) to a fault tolerant state. The rebuild operates at the VDisk level and has
no knowledge of Volumes or customer data contained therein.
A customer could have a single small Volume on a large VDisk. During the rebuild, even after it has
completed the stripes where the Volume resides, the VDisk remains in a degraded or critical state. During this
period, another drive failure would take the VDisk from degraded to critical, or from critical to down. In the
latter case, the customer may have lost data. In the prior case, the customer’s data becomes at risk once
again, even though that area of the VDisk had been rebuilt.
In another example, the customer may have created a Volume or Volumes consuming the entire VDisk space,
but may have actually allocated very little. Since linear storage has no means to know what stripes contain
customer data and which do not, that small amount of data will remain at risk until the entire VDisk has been
rebuilt. Also, performance suffers during the entire rebuild.
Another exposure is encountering a media error. If the array is rebuilding two drives and encounters a media
error on a third, the rebuild will fail. This leaves the VDisk in a critical state, exposed, and with no way to
rebuild the VDisk. It is especially unfortunate if this media error resides in unallocated space. The outcome is
the same, linear storage must assume all stripes contain customer data.
With the introduction of Virtual Storage, we have a new set of technologies to improve these conditions.
RealStor 2.0 enables Virtual Disk Pools which track how much data has been allocated for each Volume and
where it resides in the Pool, at a granularity of 4 MB. The Virtual Pool algorithm decides where to allocate
each new 4 MB page.
Advantages of Quick Rebuild:
 LUNs are spread across many RAID sets. So one RAID set rebuilding only affects a fraction of all disk
I/Os.
 Less rebuild work to do – so affected disks can return to full performance quickly.
 Volumes become fault tolerant more quickly – user data is restored to full protection more quickly.
 The rate of a RAID rebuild is directly proportional to the amount of unused disk space in a Virtual Disk
Pool.
8.6.
Advanced Copy Services / Snapshots
Unlike prior AssuredSAN arrays which use VDisks, RealStor 2.0 users will create storage pools by creating
and adding Virtual Disk Groups into a Virtual Disk Pool. The new copy services will run within these pools
and leverage the new storage page design. RealStor 2.0 will allow the existing COW snapshots and the new
Virtual Snapshots for Virtual Disk Pools to coexist on the same system.

8.6.1. Differences between Copy on Write (COW) and Redirect on Write:
The biggest differences between the two types of snapshots are the underlying technique used to manage the
location of the data that needs to be preserved. When an application writes to a disk using COW, the
snapshot engine copies the contents of the block(s) being overwritten to a new location (snapshot pool),
whereas Redirect on Write snapshots write the new data to a new page in the storage pool and updates the
internal pointers to indicate the location of the most up to date copy of the data.
Where COW requires three I/O’s to complete the operation, Redirect on Write only requires one I/O (write
the new data to disk). The advantage of this is the host application does not suffer the inherent performance
penalties that exist with the legacy COW snapshots.
8.6.2. Redirect on write snapshot overview:
A snapshot is in theory a new volume with pointers that reference the original volume’s data. To do this we
create a new volume for all new incoming writes, create page tables and data structures within the storage
pool that duplicate the original volume to keep track of all references for the volume.
A reference count in the page tables is used for each allocated page in a volume to record how many volumes
(snapshots) use it. Since reference counts are shared by multiple volumes (snapshots), they are not stored with
the volume. They are instead kept in the component object in cache for fast access.
If the volume reference count is 1 then writes will continue as if the volume were a standard volume. If the
reference count increases copy services will know a snapshot of that volume has been taken and allocate a
new page from the storage pool. When a snapshot is deleted the volume reference count is reduced by 1 and
the relevant volume (snapshot) is deleted.
Some Frequently Asked Questions about the new design:
Q:
Is a snapshot pool required to use the new copy service?
A:
No, the new design removes the requirement for a snapshot pool. There is a small volume created
within the storage pool for pointers.
Q:
A:
Are there any performance penalties using the new copy services?
No, as each volume (or snapshot) is treated as a standard volume with reference pointers back to the
source volume, snapshots have the same performance profile as the original source volume.
Q:
A:
Are there performance implications when deleting one or multiple snapshots?
No, all information relating to snapshots is using reference pointers, once these pointers are deleted
the virtual storage services de-allocates the required pages from the overall system map.
Q:
A:
Can a snapshot of a snapshot be taken?
Yes, due to the new design of copy services each snapshot is treated as a peer volume and has all the
functionality of the original volume.
Q:
A:
Can the new copy services snapshots be used with standard linear VDisks?
No, virtual storage and storage pools are not compatible with traditional VDisks
Q:
A:
Can multiple volumes be snapshotted at the same time?
Yes, this functionally is similar the existing DMS functions.
Q:
A:
Are snapshots with the new copy services application consistent?
Yes, new copy services support Microsoft VSS and VMware VAAI, consistency outside of these
areas will require scripting and sample scripts can be provided.

8.7.RealTier 2.0 and SSD read cache.
8.7.1. Autonomic Sub-LUN Tiering:
Disk tiers are comprised of aggregating 1 or more disk groups (RAID groups) that exhibit similar
characteristics in speed and density. There are 3 tiers:
1.
2.
3.
A Performance tier with SSDs
A Standard tier with Enterprise SAS HDDs
An Archive tier with Midline SAS HDDs
Prior to Autonomic Sub-LUN Tiering, LUN-level tiers are manually created and managed by using dedicated
vdisks and volumes. Applications requiring the highest performance are given volumes on top of the SSDbased vdisks while those requiring the lower performance, but greater capacity are typically are dedicated to a
vdisk comprised of Enterprise SAS or midline SAS HDDs.
LUN-level tiering is inflexible and inefficient:
 Manual tiers act as static repositories, trapping data in one tier during dynamic workload changes
 Cold data trapped in the performance tier limits the amount high-performing disks that can
be brought to bear to a dynamic workload
 Hot data trapped in the standard or archive tiers will underperform when needed the most;
the controller cache usually isn’t large enough to deal with this issue
 Migration between tiers requires external migration software or a cumbersome, backup/restore
cycle.
 Movement at the LUN-level is inefficient; the entire LUN must be migrated when typically only
portions of the LUN are being referenced by the applications.
RealStor alleviates all of these issues because it seamlessly migrates data between tiers on-demand. Dynamic
data workloads are based upon algorithms that reveal “hot” data – those which are consistently accessed with
dynamic reads/writes. This feature is called Autonomic Tiering.
Autonomic Tiering is accomplished via a concept called “paging”. User volumes are logically broken down
into small, 4MB chunks, called pages. Pages are ranked based upon a sophisticated algorithm. The page rank
is used to very efficiently select good pages to move between tiers. The result is that pages can be migrated
between tiers automatically such that I/O’s are optimized in real-time.
The figure below captures this concept. Note that 3 pages have been moved from the Enterprise SAS Tier to
the SSD Tier, 1 page from the Midline SAS Tier to the SSD Tier, and a single page has been moved down
from the SSD Tier to the SAS Tier.
Key Concept:
In contrast to data movement at the LUN-level, the Sub-LUN nature of paging provides highly efficient data
movement, a minimum of CPU and memory resources are needed to support data movement between tiers;
therefore, movement can happen in real-time rather than in offline batch movements.
Page | 32
Config Guide
AssuredSAN 4xx4
One can monitor the migration between tiers from the Storage Management Console. Notice the IOPS
status bar at the bottom Figure 2. This screen shot was captured 5 minutes after the start of a 100% random
100% write workload on a 10GB volume. The red portion of the status bar reflects those IOPS being served
from the SSD tier, and the green portion of the status bar reflects those IOPS being served from the standard
HDD tier.
Notice that only a small portion of the IOPS are coming from the SSD tier.
Percent of IO from the Two Tiers
Volumes must be created from virtual storage pools to benefit from Autonomic tiering. Volumes created
from Linear Storage Pools (previously called VDisks) cannot take advantage of the benefits of paging and
sub-LUN tiering.
Autonomic SSD Tiering eliminates rigid hardware silos, cumbersome manual migration between tiers and
can improve $/IOPs metrics
8.7.2. Read Cache
A read cache is a special-purpose disk group dedicated to hold volatile copies of data within one or more
SSDs. An SSD read cache is a new concept in RealStor 2.0.
Some advantages of a read cache are:
 Improved performance in read-centric workloads where maximum IOPS is crucial
 Requires fewer SSDs when compared to a dedicated SSD tier.
 A single SSD disk can be used as a read cache for a storage pool; whereas, an SSD tier requires
multiple disk to provide fault tolerance.
 Takes advantage of tiering-like algorithms so that only active pages are copied into the read cache.
 Active pages can be from any volume within the pool.
The read cache becomes active when the controller cache is saturated. The controller cache software gives
“hints” to the system software about which pages it would like to keep, but can’t. The system then copies
these pages into the read cache. Reads are served from the SSD, and writes are written to both SSD and
HDD.

A read cache is created using the Add Disk Group dialog box. From the SMU:
 Click on the “Pools” icon in the navigation menu to the left.
 Click the “Action” menu, and select the “Add Disk Group” menu item.
8.7.3. Key CLI Commands for RealTier 2.0 and Read Cache:
The CLI may be used to create disks groups for Autonomic Tiers and Read Cache. Figures 4-6 demonstrate
the creation of a read cache, the viewing of disk groups, and the deletion of a disk group respectively. The
examples highlight a read cache, but the commands may be used for any type of tier.

General
13.1.
NEBS level-3 certification
Dot Hill uses UL for Safety Certifications and Nationally Recognized Test Lab (NRTL) for EMC and NEBS
compliance testing. Dot Hill 2U12 and 2U24 products also have TUV-GS mark for ease of shipment within
Germany. Dot Hill uses the following definitions for products regarding NEBS:
Dot Hill Systems (DHS) Data Storage Arrays may be designed to meet NEBS requirements depending upon
customer demand. In order to simplify the definitions of how Dot Hill documents different NEBS
requirements, the definitions used below document what this means for Dot Hill products:
1)
Compliant
i.
indicates we have designed the product to pass the standard but have not completed all the
necessary testing.
2)
Declaration of Conformance
i.
indicates that all necessary testing is complete and DHS “DECLARES” we have conducted all
testing to the standards.
3)
Certified NEBS
i.
indicates that all necessary nesting is complete and DHS “DECLARES” we have conducted all
testing to the standards in a NEBS certified test laboratory.
Dot Hill 2U12 and 2U24 product lines are NEBS Compliant. Dot Hill 2U48 is only available in AC PSU
(power supply unit) at the present time, and is not NEBS Compliant. Dot Hill 4U56 will meet Dot Hill
Declaration of Conformance upon completion of testing in January 2015.
13.2.
Super Capacitors
Dot Hills EcoStorTM Battery-Free Protection provides battery elimination with patented flash alternative (aka
super capacitors) providing 10+ years in service time compared to 2-3 year battery life. There is a single
Super Capacitor within each controller from Dot Hill.
Additional benefits for Super Capacitors include:
 Reduces costs:
 No downtime for replacement
 No FRU to track & stock
 No hazardous waste disposal
 No battery replacement cost
 Elimination of service calls
Super Capacitors are a competitive advantage for Dot Hill. Some competitors use battery packs and its 10Wh
versus Dot Hill’s 0.1Wh. In other words, competitors need 50-100x the energy to back up write cache to NV
memory. They also need 50-100x the time to recharge a fully dissipated battery before they can be protecting
the write cache after a power on.
13.3.
SimulCacheTM Technology
SimulCache leverages redundant RAID controllers, thus eliminating the performance degradation associated
with conventional cache mirroring. The implementation of a high-speed dedicated PCI-Express bus
streamlines write performance resulting in superior overall system responsiveness driving faster application
throughput in database-related deployments. This can benefit companies by increasing the number of
transactions they can process - i.e. by booking more airline reservations, or more stock trades -- driving
increased revenues. SimulCacheTM Technology provides:

Patented High Performance /Low Latency Cache Mirroring
•
Better Write Performance
•
Mirrored writes 92% as efficient as non-mirrored
•
Reduces load on controller processor & I/O Bus
•
Better Data Protection with redundancy
13.4.
Data-In-Place (DIP) Migration
Traditional RAID:
Data-in-place is supported for 4000 (Chromium FX) to 4004 GL200.
Data-in-place is not supported at this time for 3xxx to 4xx4 due to variety of chassis types in the field.
Virtual:
Data-in-place migration is not supported for traditional RAID (linear) to virtual storage through our internal
DMS array based SW. This can be achieved via DHS Data Migration Services, offered by DHS PS team. The
system shall not allow a target based migration path from linear to virtual storage. Also not supported is the
data-in-place migration from virtual to linear.
