All the processors that can be ordered with the PRIMERGY RX2550 M1, apart from Xeon E5-2403 v2 and
®
Xeon E5-2407 v2, support Intel Turbo Boost Technology 2.0. This technology allows you to operate the
processor with higher frequencies than the nominal frequency. Listed in the processor table is "Max. Turbo
Frequency" for the theoretical frequency maximum with only one active core per processor, whereas "Max.
All-Core Turbo Frequency" specifies the theoretical frequency maximum when all the cores of a processor
are active. The maximum frequency that can actually be achieved depends on the number of active cores,
the current consumption, electrical power consumption and the temperature of the processor.
As a matter of principle Intel does not guarantee that the maximum all-core turbo frequency will be reached.
This is related to manufacturing tolerances, which result in a variance regarding the performance of various
examples of a processor model. The range of the variance covers the entire scope between the nominal
frequency and the maximum all-core turbo frequency.
The turbo functionality can be set via BIOS option. Fujitsu generally recommends leaving the "Turbo Mode"
option set at the standard setting "Enabled", as performance is substantially increased by the higher
frequencies. However, since the higher frequencies depend on general conditions and are not always
guaranteed, it can be advantageous to disable the "Turbo Mode" option for application scenarios with
intensive use of AVX instructions and a high number of instructions per clock unit, as well as for those that
require constant performance or lower electrical power consumption.

SPECcpu2006
Benchmark description
SPECcpu2006 is a benchmark which measures the system efficiency with integer and floating-point
operations. It consists of an integer test suite (SPECint2006) containing 12 applications and a floating-point
test suite (SPECfp2006) containing 17 applications. Both test suites are extremely computing-intensive and
concentrate on the CPU and the memory. Other components, such as Disk I/O and network, are not
measured by this benchmark.
SPECcpu2006 is not tied to a special operating system. The benchmark is available as source code and is
compiled before the actual measurement. The used compiler version and their optimization settings also
affect the measurement result.
SPECcpu2006 contains two different performance measurement methods: the first method (SPECint2006 or
SPECfp2006) determines the time which is required to process single task. The second method
(SPECint_rate2006 or SPECfp_rate2006) determines the throughput, i.e. the number of tasks that can be
handled in parallel. Both methods are also divided into two measurement runs, “base” and “peak” which
differ in the use of compiler optimization. When publishing the results the base values are always used; the
peak values are optional.

The measurement results are the geometric average from normalized ratio values which have been
determined for individual benchmarks. The geometric average - in contrast to the arithmetic average - means
that there is a weighting in favour of the lower individual results. Normalized means that the measurement is
how fast is the test system compared to a reference system. Value “1” was defined for the
SPECint_base2006-, SPECint_rate_base2006, SPECfp_base2006 and SPECfp_rate_base2006 results of
the reference system. For example, a SPECint_base2006 value of 2 means that the measuring system has
handled this benchmark twice as fast as the reference system. A SPECfp_rate_base2006 value of 4 means
that the measuring system has handled this benchmark some 4/[# base copies] times faster than the
reference system. “# base copies” specify how many parallel instances of the benchmark have been
executed.
Not every SPECcpu2006 measurement is submitted by us for publication at SPEC. This is why the SPEC
web pages do not have every result. As we archive the log files for all measurements, we can prove the
correct implementation of the measurements at any time.

In terms of processors the benchmark result depends primarily on the size of the processor cache, the
support for Hyper-Threading, the number of processor cores and on the processor frequency. In the case of
processors with Turbo mode the number of cores, which are loaded by the benchmark, determines the
maximum processor frequency that can be achieved. In the case of single-threaded benchmarks, which
largely load one core only, the maximum processor frequency that can be achieved is higher than with multithreaded benchmarks (see the processor table in the section "Technical Data").

SPECpower_ssj2008
Benchmark description
SPECpower_ssj2008 is the first industry-standard SPEC benchmark that evaluates the power and
performance characteristics of a server. With SPECpower_ssj2008 SPEC has defined standards for server
power measurements in the same way they have done for performance.
The benchmark workload represents typical server-side Java business applications. The workload is
scalable, multi-threaded, portable across a wide range of platforms and easy to run. The benchmark tests
CPUs, caches, the memory hierarchy and scalability of symmetric multiprocessor systems (SMPs), as well
as the implementation of Java Virtual Machine (JVM), Just In Time (JIT) compilers, garbage collection,
threads and some aspects of the operating system.
SPECpower_ssj2008 reports power consumption for
servers at different performance levels — from 100% to
“active idle” in 10% segments — over a set period of
time. The graduated workload recognizes the fact that
processing loads and power consumption on servers
vary substantially over the course of days or weeks. To
compute a power-performance metric across all levels,
measured transaction throughputs for each segment are
added together and then divided by the sum of the
average power consumed for each segment. The result
is a figure of merit called “overall ssj_ops/watt”. This
ratio provides information about the energy efficiency of
the measured server. The defined measurement
standard enables customers to compare it with other
configurations
and
servers
measured
with
SPECpower_ssj2008. The diagram shows a typical
graph of a SPECpower_ssj2008 result.
The benchmark runs on a wide variety of
operating
systems
and
hardware
architectures and does not require extensive
client or storage infrastructure. The minimum
equipment for SPEC-compliant testing is two
networked computers, plus a power analyzer
and a temperature sensor. One computer is
the System Under Test (SUT) which runs
one of the supported operating systems and
the JVM. The JVM provides the environment
required to run the SPECpower_ssj2008
workload which is implemented in Java. The
other computer is a “Control & Collection
System” (CCS) which controls the operation
of the benchmark and captures the power,
performance and temperature readings for
reporting. The diagram provides an overview
of the basic structure of the benchmark
configuration and the various components.

Disk I/O: Performance of storage media
Benchmark description
Performance measurements of disk subsystems for PRIMERGY servers are used to assess their
performance and enable a comparison of the different storage connections for PRIMERGY servers. As
standard, these performance measurements are carried out with a defined measurement method, which
models the accesses of real application scenarios on the basis of specifications.
The essential specifications are:
 Share of random accesses / sequential accesses
 Share of read / write access types
 Block size (kB)
 Number of parallel accesses (# of outstanding I/Os)
A given value combination of these specifications is known as “load profile”. The following five standard load
profiles can be allocated to typical application scenarios:
Standard load

In order to model applications that access in parallel with a different load intensity, the “# of Outstanding
I/Os” is increased, starting with 1, 3, 8 and going up to 512 (from 8 onwards in increments to the power of
two).
The measurements of this document are based on these standard load profiles.
The main results of a measurement are:



Throughput [MB/s]
Transactions [IO/s]
Latency [ms]
Throughput in megabytes per second
Transaction rate in I/O operations per second
Average response time in ms
The data throughput has established itself as the normal measurement variable for sequential load profiles,
whereas the measurement variable “transaction rate” is mostly used for random load profiles with their small
block sizes. Data throughput and transaction rate are directly proportional to each other and can be
transferred to each other according to the formula
Data throughput [MB/s]
= Transaction rate [IO/s] × Block size [MB]
Transaction rate [IO/s]
= Data throughput [MB/s] / Block size [MB]
12
This section specifies capacities of storage media on a basis of 10 (1 TB = 10 bytes) while all other
20
capacities, file sizes, block sizes and throughputs are specified on a basis of 2 (1 MB/s = 2 bytes/s).
All the details of the measurement method and the basics of disk I/O performance are described in the white
paper “Basics of Disk I/O Performance”.

Benchmark results
The results shown here are intended to help you select the appropriate storage media for the models of the
PRIMERGY RX2520 M1 under the aspect of disk-I/O performance. For this purpose, a single storage
medium was measured in the configuration specified in the subsection Benchmark environment. The RAID
controller RAID Ctrl SAS 6G 0/1 (D2607) was used for the measurements. The following table summarizes
its most important features.

*) partly also available with a 3.5" tray
Of all the hard disk types SSDs offer by far the highest transaction rates for random load profiles as well as
the shortest access times. In return, however, the price per gigabyte of storage capacity is substantially
higher.
Cache settings
In most cases, the cache of HDDs has a great influence on disk-I/O performance. It is frequently regarded as
a security problem in case of power failure and is thus switched off. On the other hand, it was integrated by
hard disk manufacturers for the good reason of increasing the write performance. For performance reasons it
is therefore advisable to enable the hard disk cache. To prevent data loss in case of power failure you are
recommended to equip the system with a UPS.
For the purpose of easy and reliable handling of the settings for RAID controllers and hard disks it is
advisable to use the RAID-Manager software “ServerView RAID” that is supplied for PRIMERGY servers. All
the cache settings for controllers and hard disks can usually be made en bloc – specifically for the
application – by using the pre-defined modi “Performance” or “Data Protection”. The “Performance” mode
ensures the best possible performance settings for the majority of the application scenarios.

Performance values
The performance values of the PRIMERGY RX2520 M1 are summarized in the following tables, in each case
specifically for a single storage medium and with various access types and block sizes. The established sets
of measurements, as already mentioned in the subsection Benchmark description, are used here. Thus,
transaction rate is specified for random accesses and data throughput for sequential accesses. To avoid any
confusion among the measurement units the tables have been separated for the two access types.
The table cells contain the maximum achievable values. This means that each value is the maximum
achievable value of the whole range of load intensities (# of Outstanding I/Os). In order to also visualize the
numerical values each table cell is highlighted with a horizontal bar, the length of which is proportional to the
numerical value in the table cell. All bars shown in the same scale of length have the same color. In other
words, a visual comparison only makes sense for table cells with the same colored bars. Since the horizontal
bars in the table cells depict the maximum achievable performance values, they are shown by the color
getting lighter as you move from left to right. The light shade of color at the right end of the bar tells you that
the value is a maximum value and can only be achieved under optimal prerequisites. The darker the shade
becomes as you move to the left, the more frequently it will be possible to achieve the corresponding value
in practice.

In order to model applications that access in parallel with a different load intensity, the “# of Outstanding
I/Os” is increased, starting with 1, 3, 8 and going up to 512 (from 8 onwards in increments to the power of
two).
The measurements of this document are based on these standard load profiles.
The main results of a measurement are:



Throughput [MB/s]
Transactions [IO/s]
Latency [ms]
Throughput in megabytes per second
Transaction rate in I/O operations per second
Average response time in ms
The data throughput has established itself as the normal measurement variable for sequential load profiles,
whereas the measurement variable “transaction rate” is mostly used for random load profiles with their small
block sizes. Data throughput and transaction rate are directly proportional to each other and can be
transferred to each other according to the formula
Data throughput [MB/s]
= Transaction rate [IO/s] × Block size [MB]
Transaction rate [IO/s]
= Data throughput [MB/s] / Block size [MB]
12
This section specifies capacities of storage media on a basis of 10 (1 TB = 10 bytes) while all other
20
capacities, file sizes, block sizes and throughputs are specified on a basis of 2 (1 MB/s = 2 bytes/s).
All the details of the measurement method and the basics of disk I/O performance are described in the white
paper “Basics of Disk I/O Performance”.

Benchmark results
The results presented here are designed to help you choose the right solution from the various configuration
options of the PRIMERGY RX2520 M1 in the light of disk-I/O performance. Various combinations of RAID
controllers and storage media will be analyzed below. Information on the selection of storage media
themselves is to be found in the section “Disk I/O: Performance of storage media”.
Hard disks
The hard disks are the first essential component. If there is a reference below to “hard disks”, this is meant
as the generic term for HDDs (“hard disk drives”, in other words conventional hard disks) and SSDs (“solid
state drives”, i.e. non-volatile electronic storage media).
Mixed drive configurations of SAS and SATA hard disks in one system are permitted, unless they are
excluded in the configurator for special hard disk types.
More hard disks per system are possible as a result of using 2.5" hard disks instead of 3.5" hard disks.
Consequently, the load that each individual hard disk has to overcome decreases and the maximum overall
performance of the system increases.
More detailed performance statements about hard disk types are available in the section “Disk I/O:
Performance of storage media” in this performance report.
Model versions
The maximum number of hard disks in the system depends on the system configuration. The following table
lists the essential cases.

RAID controller
In addition to the hard disks the RAID controller is the second performance-determining key component. In
the case of these controllers the “modular RAID” concept of the PRIMERGY servers offers a plethora of
options to meet the various requirements of a wide range of different application scenarios.
The following table summarizes the most important features of the available RAID controllers of the
PRIMERGY RX2520 M1. A short alias is specified here for each controller, which is used in the subsequent
list of the performance values.

The onboard RAID controller is implemented in the chipset Intel C600 on the system board of the server and
uses the CPU of the server for the RAID functionality. This controller is a simple solution that does not
require a PCIe slot. In addition to the invariably available connection option of SATA hard disks, the
additional SAS functionality can be activated via an “SAS enabling key”.
System-specific interfaces
The interfaces of a controller to the system board and to the hard disks have in each case specific limits for
data throughput. These limits are listed in the following table. The minimum of these two values is a definite
limit, which cannot be exceeded. This value is highlighted in bold in the following table.

Controller Performance”.

Settings
In most cases, the cache of HDDs has a great influence on disk-I/O performance. It is frequently regarded as
a security problem in case of power failure and is thus switched off. On the other hand, it was integrated by
hard disk manufacturers for the good reason of increasing the write performance. For performance reasons it
is therefore advisable to enable the hard disk cache. To prevent data loss in case of power failure you are
recommended to equip the system with a UPS.
In the case of controllers with a cache there are several parameters that can be set. The optimal settings can
depend on the RAID level, the application scenario and the type of data medium. In the case of RAID levels
5 and 6 in particular (and the more complex RAID level combinations 50 and 60) it is obligatory to enable the
controller cache for application scenarios with write share. If the controller cache is enabled, the data
temporarily stored in the cache should be safeguarded against loss in case of power failure. Suitable
accessories are available for this purpose (e.g. a BBU or FBU).
For the purpose of easy and reliable handling of the settings for RAID controllers and hard disks it is
advisable to use the RAID-Manager software “ServerView RAID” that is supplied for PRIMERGY servers. All
the cache settings for controllers and hard disks can usually be made en bloc – specifically for the
application – by using the pre-defined modi “Performance” or “Data Protection”. The “Performance” mode
ensures the best possible performance settings for the majority of the application scenarios.
More information about the setting options of the controller cache is available in the white paper “RAID
Controller Performance”.
Performance values
In general, disk-I/O performance of a RAID array depends on the type and number of hard disks, on the
RAID level and on the RAID controller. If the limits of the system-specific interfaces are not exceeded, the
statements on disk-I/O performance are therefore valid for all PRIMERGY systems. This is why all the
performance statements of the document “RAID Controller Performance” also apply for the PRIMERGY
RX2520 M1 if the configurations measured there are also supported by this system.
The performance values of the PRIMERGY RX2520 M1 are listed in table form below, specifically for
different RAID levels, access types and block sizes. Substantially different configuration versions are dealt
with separately. The tables use the established measurement variables, as already mentioned in the
subsection Benchmark description. Thus, transaction rate is specified for random accesses and data
throughput for sequential accesses. To avoid any confusion among the measurement units the tables have
been separated for the two access types.
The table cells contain the maximum achievable values. This has three implications: On the one hand hard
disks with optimal performance were used (the components used are described in more detail in the
subsection Benchmark environment). Furthermore, cache settings of controllers and hard disks, which are
optimal for the respective access scenario and the RAID level, are used as a basis. And ultimately each
value is the maximum value for the entire load intensity range (# of outstanding I/Os).
In order to also visualize the numerical values each table cell is highlighted with a horizontal bar, the length
of which is proportional to the numerical value in the table cell. All bars shown in the same scale of length
have the same color. In other words, a visual comparison only makes sense for table cells with the same
colored bars.
Since the horizontal bars in the table cells depict the maximum achievable performance values, they are
shown by the color getting lighter as you move from left to right. The light shade of color at the right end of
the bar tells you that the value is a maximum value and can only be achieved under optimal prerequisites.
The darker the shade becomes as you move to the left, the more frequently it will be possible to achieve the
corresponding value in practice.

STREAM
Benchmark description
STREAM is a synthetic benchmark that has been used for many years to determine memory throughput and
which was developed by John McCalpin during his professorship at the University of Delaware. Today
STREAM is supported at the University of Virginia, where the source code can be downloaded in either
Fortran or C. STREAM continues to play an important role in the HPC environment in particular. It is for
example an integral part of the HPC Challenge benchmark suite.
The benchmark is designed in such a way that it can be used both on PCs and on server systems. The unit
of measurement of the benchmark is GB/s, i.e. the number of gigabytes that can be read and written per

STREAM measures the memory throughput for sequential accesses. These can generally be performed
more efficiently than accesses that are randomly distributed on the memory, because the CPU caches are
used for sequential access.
Before execution the source code is adapted to the environment to be measured. Therefore, the size of the
data area must be at least four times larger than the total of all CPU caches so that these have as little
influence as possible on the result. The OpenMP program library is used to enable selected parts of the
program to be executed in parallel during the runtime of the benchmark, consequently achieving optimal load
distribution to the available processor cores.
During implementation the defined data area, consisting of 8-byte elements, is successively copied to four
types, and arithmetic calculations are also performed to some extent.

The throughput is output in GB/s for each type of calculation. The differences between the various values are
usually only minor on modern systems. In general, only the determined TRIAD value is used as a
comparison.
The measured results primarily depend on the clock frequency of the memory modules; the CPUs influence
the arithmetic calculations. The accuracy of the results is approximately 5%.

This chapter specifies throughputs on a basis of 10 (1 GB/s = 10 Byte/s).

The results depend primarily on the maximum memory frequency. The processors with only 4 cores, which
do not fully utilize their memory controller, are an exception. The smaller differences with processors with the
same maximum memory frequency are a result in arithmetic calculation of the different processor
frequencies.
