Requirements, Best Practices and Limitations
 Hardware requirements:
– DS5100 or DS5300
– Power servers (Power blades not supported for direct attachment)
– POWER6 hardware
– POWER5(+) hardware not supported
– Smart I/O adapter (IOPless adapter)
#5735 (8Gb dual-port PCI-E)
#5774 (4Gb dual-port PCI-E)
#5749 (4Gb dual-port PCI-X)
 Software requirements:
– IBM i 6.1 with IBM 6.1.1 LIC refresh
– IBM i 5.4.5 or earlier not supported
– 7.60.26.00 or later DS5100 or DS5300 controller firmware
 Best Practices and limitations:
– Maximum LUN size for IBM i is < 2TB (volume size >= 2TB will not work)
– Mixing FC and SATA drives within enclosure is supported
– FC drives recommended for production workloads
– Maximum 64 LUNs per FC port (same as DS8000 direct attach)
– SSDs not supported at this time
– Drive encryption in DS5100/DS5300 is supported
– Boot from SAN requires active connection, IBM i will not IPL from passive connection
– Maximum of 300 LUNs from a single DS5100/DS5300 per ASP add
Adding more LUNs to same ASP requires multiple ASP adds
– All LUNs must be protected (RAID0 arrays for LUNs not supported)
– Dynamic volume expansion on DS5100 and DS5300 is not supported
– IBM i system-level disk mirroring not supported
Disk protection configured on DS5100 or DS5300
Drives report in IBM i as protected (same as DS8000 protected LUNs)

Configuring DS5100 and DS5300 for IBM i Direct Attachment – Storage
 Step 1: Perform sizing
– Use Disk Magic for DDM/array sizing, use PCRM* for LUN sizing
– Number of physical drives is still most important
– Separate LUNs for production and development workloads on different RAID arrays
– Array and LUN configuration for IBM i is different from that for AIX direct or for AIX through VIOS
– Leverage service vouchers for assistance (see later in this presentation)
 Step 2: Use DS5100 and DS5300 Redbook (SG-247676) to perform initial DS5100 and DS5300 setup
 Step 3: Create RAID5, RAID6 or RAID10 array
 Step 4: Create 512B LUNs based on Disk Magic sizing
 Step 5: Create new host, type IBM i
 Step 6: Map LUNs to new host
 Make sure there are no hosts in default host group on DS5100/DS5300
DS Storage Manager
– Storage partitioning recommended
– IBM i will see LUNs attached to any host in the default host group in addition to its own hosts
without storage partitioning

Configuring DS5100 and DS5300 for IBM i Direct Attachment – Power System
 Create IBM i LPAR, assign supported FC adapter(s), OR
 Assign supported FC adapters to existing IBM i LPAR
 Perform zoning
– Zone each port on the FC adapter to connect to controller A or B
– Maximizes redundancy and performance
 Connect FC adapters to SAN fabric
– See note on default host group on DS5100/DS5300 before performing this step

Comparison with DS5100 and DS5300 Attachment to IBM i through VIOS
 Performance:
– Performance is expected to be similar in both environments
– Direct attachment will not provide better performance
– VIOS does not add significant overhead
 Skills:
– DS5100 and DS5300 and IBM i skills required
– VIOS skills not required
 Copy Services and replication:
– DS5100 and DS5300 Flash Copy, Metro Mirror and Global Mirror supported for IBM i
attachment through VIOS
Full-system only
IASPs not supported
– IBM is investigating supporting Copy Services with direct attachment
– PowerHA for i Geographic Mirroring is supported in both environments

NPIV Benefits for IBM i
 Sharing dual-port 8Gb FC adapters among multiple partitions
– One port from 2 separate adapters can be shared to same client partition, allowing for
adapter redundancy
 Support for FC tape libraries in VIOS environment
– Tape library recognized with device-specific machine-type and model (MTM) in IBM i and
all library functions supported
 Support for DS8000 storage
– Volumes recognized with device-specific MTM and as protected or unprotected
 Support for DS8000 Copy Services with PowerHA in a VIOS environment
– Similar to natively attached DS8000 today

IBM i Support for XIV
20

IBM i supports the XIV Storage System with PowerVM
VIOS to leverage the innovative subsystem’s ease of
management and performance

XIV benefits
– Massive parallelism (all disk units used at all times)
– Easy upgradeability
– Simplified configuration
– Unlimited snapshots with little effect on performance

VIOS can virtualize XIV storage to IBM i, AIX, Linux
– PowerVM VIOS configurations with IBM i 6.1 partitions
– POWER6 processor-based servers and blades

XIV performance for IBM i
– Performance falls between DS5000 and DS8000,
closer to DS5000
– Performance requirements for all workloads moving to
XIV should be carefully evaluated to verify the storage
will be able to deliver adequate performance for IBM i
