SAP HANA
SAP HANA converges database and application platform capabilities in-memory to transform transactions, analytics, text
analysis, predictive and spatial processing so businesses can operate in real-time. This combines database, data
processing, and application platform capabilities in a single in-memory platform. Also, the platform provides libraries for
predictive, planning, text processing, spatial, and business analytics — all on the same architecture.
By eliminating the divide between transactions and analytics, SAP HANA allows you to answer any business question
anywhere in real time.

Network
Architecture
There are two 10GBASE-SR 2-port LAN adapters installed on the PCIe slots of the I/O board module of server blade 1 of
the Hitachi Compute Blade 2500 chassis. The solution uses two 10 GbE ports on the 10GBASE-SR 2-port LAN adapters
for connectivity with the 10 GbE external switches.
Connect the management module on the Hitachi Compute Blade 2500 chassis to an external switch for management
connectivity.
Make the following network connections for the client network setup of the SAP HANA node as an uplink network setup:


Connect the following to the external switches:

Port 0 of the I/O board module on PCIe slot IOBD 01B.

Port 0 of the I/O board module on PCIe slot IOBD 02B.
Bond the corresponding two ports eth9901 and eth9902 as bond0 at the operating system level.

Use active-active network bond mode with these options:
mode= 802.3ad miimon=100 xmit_hash_policy=layer3+4 updelay=5000 lacp_rate=fast


This acts as the client network for the SAP HANA node.
Configure the external switch ports with a short LACP timeout value to speed up detecting corrupted connections.
The compute network setup uses the ports on the 10GBASE-SR 2-port LAN adapters, as listed in Table 9.

For LUN assignment, use the host IDs defined in Table 12 to configure host groups on VSP G200. To support high
availability, each LUN has multiple paths from the host within Hitachi Compute Blade 2500 to multiple ports on VSP G200
storage.
Table 7, “Fibre Channel Port Mapping,” on page 11 lists which ports are used for different sized configurations.
There are four MP units (MPU) used to distribute the workload for all LUNs needed for the solution.
SAP HANA Configuration
This section explains the SAP HANA configuration.
Operating System Volume Configuration
The SAP HANA Scale-Up configuration requires a OS volume. It uses one 100 GB LUN on Hitachi Virtual Storage Platform
G200 for the operating system volume for the SAP HANA appliance.
The four ports of the 16 Gb/sec Hitachi FIVE-FX Fibre Channel 2-port adapters have the 100 GB operating system LUN
configured as the primary boot device. The operating system LUN holds partitions for SUSE Linux for SAP Applications or
Red Hat Linux on the OS LUN, /usr/sap/ and the Linux swap space.
Activate Device-Mapper Multipath
This reference architecture uses Device-mapper Multipath, a component of the native Linux operating system.
Using Device-mapper Multipath allows the configuration of multiple I/O paths between the server blades, and Hitachi
Virtual Storage Platform G200 Multipathing aggregates all physical I/O paths into a single logical path. The LUNs are
always available, unless all four paths fail.
Device-mapper Multipath is used for the following I/O paths:

SAP HANA server boot LUN.

SAP HANA data volume LUN.

SAP HANA log volume LUN.

SAP HANA shared volume LUN.

24 HANA Data Volume Configuration
SAP
The Logical Volume Manager configures the SAP HANA persistent storage volumes. Table 12, “Parity Group and LDEV
Assignment for 4 TB and 6 TB Memory Sizes,” on page 22 shows the size of the SAP HANA data volume LUNs defined by
the solution.
Logical Volume Manager creates a single striped volume on which the XFS file system is created to store the SAP HANA
data volume. The striped volume acts as the persistent layer for the SAP HANA server.
Table 13, “XFS File System Creation and Mounted Options for Data and Log Volumes,” on page 24 contains options used
by striped volume creation, XFS file system creation, and mount for data volume to optimize performance.
SAP HANA Log Volumes Configuration
This reference architecture uses Logical Volume Manager to configure the SAP HANA log volumes.
With the four 150 GB SAP HANA log volume LUNs, Logical Volume Manager creates a single four-way striped volume on
which the XFS file system is created to store the SAP HANA log volume.
Table 13 contains options used by striped volume creation, XFS file system creation, and mount for log volume and data
volume to optimize performance.

Note — Use this formula to calculate the XFS stripe width of a data volume: swidth = [sunit] × [total number of data
disks]. For example, with an XFS strip width of a 6 TB data volume, swidth = [1024] × [6 × 6], or 36864.

25 HANA Shared Volume
SAP
This reference architecture uses one or two LUNs for the SAP HANA shared volume for different sized solutions. Logical
Volume Manager creates a single striped volume on which the XFS file system is created to store the SAP HANA binaries,
configuration, and trace files.
To find the number and size of LUNs of the SAP HANA shared volume to create either one-way or two-way striped
volumes for different sized solutions, refer to the following:

Table 11, “Parity Group and LDEV Assignment for the Less Than or Equal to 3 TB Memory Sizes,” on page 21

Table 12, “Parity Group and LDEV Assignment for 4 TB and 6 TB Memory Sizes,” on page 22
SAP HANA Appliance Software Installation
After configuring the file system for the SAP HANA data volume and log volume, the SAP HANA SPS stack is installed on
the SAP HANA server.
The following SAP HANA software components are installed on the HANA server node:

SAP HANA database.

SAP HANA client.

SAP Host agent.
