Attention!
High Performance/Power Mode
If your BIOS has a High Performance/Power Mode, enable it when using IBM High IOPS Adapters. Also
disable any power-saving modes. This improves performance in two ways:
1. Prevents operating systems and the BIOS from suspending PCIe devices (using ASPM), including
IBM High IOPS Adapters. IBM High IOPS Adapters do not support ASPM.
2. Maintains higher fan speeds to prevent thermal throttling.
Sufficient System Memory (RAM)
The ioMemory VSL software requires enough RAM to accelerate your IBM High IOPS Adapter. The RAM
requirements depend on how your operating system tracks I/O's (average written block sizes), the capacity of your
IBM High IOPS Adapters, and the version of the ioMemory VSL software.
For more information, including a chart on RAM required per GB of IBM High IOPS Adapter capacity, consult the
IBM ioMemory VSL Release Notes
for the version of ioMemory VSL software that you will install with the device(s).
Firmware Requirements
The IBM High IOPS Adapter must have a certain level of firmware in order to work with particular versions of the
ioMemory VSL software. Consult the
Upgrade Notes
section of the
http://www.ibm.com/systems/support
for
upgrade considerations.
Attention!
Do not downgrade the IBM High IOPS Adapter to an earlier version of the firmware. Earlier versions of
the firmware may not be compatible with the device, and downgrading the firmware will result in data loss.
Contact Customer Support if you have issues with your upgrade.
