As part of VMware's ongoing testing and certification efforts on Virtual SAN compatible hardware, VMware has decided to remove these controllers from the Virtual SAN compatibility list. While fully functional, these controllers offer IO throughput that is too low to sustain the performance requirements of most VMware environments.
Because of the low queue depth offered by these controllers, even a moderate IO rate could result in IO operations timing out, especially during disk rebuild operations. In this event, the controller may be unable to cope with both a rebuild activity and running virtual machine IO causing elongated rebuild time and slow application responsiveness. To avoid issues such as this, VMware is removing these controllers from the Hardware Compatibility List.
If you have purchased Virtual SAN for use with these controllers, contact VMware Customer Service for the next steps.
Note: These Fujitsu controllers are removed from the Virtual SAN Compatibility Guide as they were added prematurely. These controllers are not affected by low queue depth.
