* Some devices may report a
nand_thermal_deg_c
value of
0
. This means that the particular device is not set to
throttle or shut down based on the NAND board temperature.
NOTE-
If your system logs indicate write-performance throttling due to high temperatures, consult your server's
documentation for details on increasing airflow within your system (for example, by increasing the fans to
maximum
speed within the system via a BIOS setting).
ATTENTION!
High Performance/Power Mode
If your BIOS has a High Performance/Power Mode, enable it when using Fusion ioMemory devices. 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 Fusion
ioMemory devices. Fusion ioMemory devices do not support ASPM.
2. Maintains higher fan speeds to prevent thermal throttling.
Sufficient System Memory (RAM)
The Fusion ioMemory VSL software requires enough RAM to accelerate your Fusion ioMemory device. The RAM
requirements depend on how your operating system tracks I/O's (average written block sizes), the capacity of your Fusion
ioMemory devices, and the version of the Fusion ioMemory VSL software.
For more information, including a chart on RAM required per GB of Fusion ioMemory device capacity, consult the
Fusion
ioMemory VSL Release Notes
for the version of Fusion ioMemory VSL software that you will install with the device(s).
Firmware Requirements
The Fusion ioMemory device must have a certain level of firmware in order to work with particular versions of the Fusion
ioMemory VSL software. Consult the
Upgrade Notes
section of

for upgrade
considerations.
