About this guide8
1 Introduction
Included:
•Overview
• Required operating environment
This document includes information on installing and maintaining your HP StorageWorks IO Accelerator
(also referenced as an IO Accelerator).
Overview
Designed around a revolutionary silicon-based storage architecture known as ioMemory, the HP
StorageWorks IO Accelerator is the world’s most advanced NAND flash storage device. With
performance comparable to DRAM and storage capacity on par with today’s hard disks, it improves
storage performance by orders of magnitude. The IO Accelerator dramatically increases performance
so that every server can contain internal storage that exceeds the I/O performance of an enterprise
SAN.
The IO Accelerator is the world’s first data accelerator designed specifically to improve the bandwidth
for I/O-bound applications. The IO Accelerator is a no-compromise solution for the toughest
computational challenges faced by data centers today, putting it in a league of its own.
Required operating environment
The HP StorageWorks IO Accelerator is supported for use in the following operating environments:
Operating systems
• SUSE LINUX Enterprise Server 10 (AMD64/EM64T)
• Red Hat Enterprise Linux 4 (AMD64/EM64T)
• Red Hat Enterprise Linux 5 (AMD64/EM64T)
• Microsoft Windows Server 2003 (x86_64-bit only) SP2
• Microsoft Windows Server 2008 (x86_64-bit only) SP1
IMPORTANT:
All operating systems must be 64-bit architecture.
Hardware
The adapter is provided in a c-Class Type 1 Mezzanine card form factor. It can be installed in both
Type 1 and Type 2 mezzanine slots within the c-Class blade servers, allowing a total of 2 cards in a
half-height server blade, and 3 cards in a full-height server blade.
IO Accelerator for BladeSystem c-Class user guide 9
The amount of free RAM required by the driver depends on the size of the blocks used when writing
to the drive. The smaller the blocks, the more RAM required. Here are the guidelines for each 80GB
of storage:
RAM usage (Megabytes)Average Block Size(bytes)

• Installing the HP StorageWorks IO Accelerator
• Verifying Hardware Installation
Installing the HP StorageWorks IO Accelerator
WARNING!
To reduce the risk of personal injury from hot surfaces, allow drives and internal system components
to cool before touching them.
WARNING!
Reduce the risk of electric shock by removing all AC power from the system before installing or
replacing any non-hot-plug hardware option. Disconnect all power cords to completely remove power
from the server.
CAUTION:
Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly
grounded (earthed) before beginning any installation procedure.
1. Remove the desired server blade from the enclosure, and then remove the server blade access
panel.
a. Identify the proper server blade in the enclosure.
b. Back up all server blade data.
c. Stop all activity on the server and then power down the server blade.
d. Remove the server blade from the enclosure.
e. Lift the access panel latch, slide the access panel to the rear, and then remove the access
panel and set aside.
2. Remove any protective covering from the IO Accelerator.
IO Accelerator for BladeSystem c-Class user guide 11
3. Install the IO Accelerator card as shown below.
The following illustration demonstrates installing the IO Accelerator on a full-height server blade.
The following illustration demonstrates installing the IO Accelerator on a half-height server blade.
4. Reinstall the server blade access panel and then reinstall the server blade in its operating position
in the server blade enclosure.
Verifying Hardware Installation
After powering up the server in the BladeSystem chassis, you can verify that the mezzanine card has
been installed correctly using the HP BladeSystem Onboard Administrator. :
Refer to the Information tab of the Device Bay containing the server blade. The "Mezzanine Card
Information" section will show if the cards have been detected properly. For example
Hardware installation12
NOTE:
The HP StorageWorks IO Accelerator does not support boot capability. Because it is a storage device,
you may see it listed in the server BIOS Boot Controller Order setup screens. However, it is not currently
supported as a boot device.

Hardware installation14
3 Linux environments
Included:
• Installation Requirements
• Downloading and installing the driver and utilities
• Adding a file system, formatting, and performing multi-disk configuration
• Using the Logical Volume Manager
• Configuring RAID
• Upgrading firmware
• Upgrading the driver
• Unmanaged Shutdown Issues
• Exploring IO Accelerator Linux Driver Loading
• Linux installation of Simple Network Management Protocol (SNMP)
Installation Requirements
The HP-provided Linux installers for the IO Accelerator do not contain binary driver modules. Instead,
they build the binary driver RPMs specific to the active Linux kernel by using a source RPM for the
driver and compiler/build tools. This allows for the use of customized kernels, but does place additional
requirements on the system used for initial installation (e.g. the 'build' system). After performing an
installation on the 'build' system, the binary driver RPM can then be deployed to other systems without
having to rebuild it.
The base modules required for the build system are summarized in the following table:
RequirementsDistro
RHEL4
RHEL5
These modules may have other dependencies that will be installed automatically assuming you are
using some type of package manager/installer. The kernel-devel (for RHEL4 and RHEL5) and
kernel-source (for SLES) modules must match the kernel version in use.
kernel (x86-64), kernel-devel (x86-64), rpm-build, rsync, redhat-lsb, gcc,
dialog
kernel (x86-64), kernel-devel (x86-64), rpm-build, rsync, redhat-lsb, gcc,
dialog
kernel-smp, kernel-source, rsync, lsb, gcc, dialogSLES10
Downloading and installing the driver and utilities
Two methods are available for installing the driver and utilities.
1. Load the USB drive shipped with the HP IO Accelerator unit
IO Accelerator for BladeSystem c-Class user guide 15
2. Download from http://www.hp.com/support; search for product named "HP StorageWorks IO
Accelerator"
Select the appropriate file(s) for your operating environment, and download the file(s).
Installing using the HP installer script
1. Download driver and utility package as described in Downloading and installing the driver and
utilities.
2. Ensure that the system you are installing to has the necessary Linux components installed:
3. Change the directory to where you placed the downloaded package and enter the following
command to begin installation (this example uses the 1.2.4 version on RHEL4):
bash iodrive-1.2.4_rhel4_installer.sh
If the dialog package is installed on your server, the installer script will present a menu to control the
installer. If the dialog package is not installed, you will see this message instead:
Performing standard install. For more advanced features of this installer
please install the dialog package.
With dialog installed, you will be able to choose whether or not to install the optional snmp and jni
packages.
NOTE:
• If you were able to install the driver proceed to Loading the driver.
• If you were unable to install please review the install.log in the IO Accelerator_files sub-directory.
Deploying the built packages
If you need to deploy the driver to other systems (e.g. systems without a complete build environment),
you can find the newly compiled binary driver RPM in the following directories:
RHEL4 and RHEL5
/usr/src/redhat/RPMS/x86_64/iodrive-driver-{VERSION}.x86_64.rpm
SLES10
/usr/src/packages/RPMS/x86_64/iodrive-driver-{VERSION}.x86_64.rpm
The other RPMs for the utilities and firmware will be located in the "IO Accelerator_files" subdirectory
where the installer script ran:
iodrive-jni-{VERSION}.x86_64.rpm
iodrive-util-{VERSION}.x86_64.rpm
iodrive-firmware-{VERSION}.noarch.rpm
iodrive-snmp-{VERSION}.x86_64.rpm
Copy these 4 files and the binary driver RPM to the target system and install them using the RPM
package manager.
