HP PCIe IO Accelerator / FusionIO works in HP DL380 G7
HP DL380 G7, firmware was upgraded with HP ProLiant Firmware Maintenance DVD v9.10C
HP 160GB SLC PCIe ioDrive - HP Part #600278-B21
FusionIO drivers and and firmware v2.2.0 for Windows were used
Windows 2008 R2 VM with 2 vCPUs and 4GB RAM allocated.
I was able to update the firmware on the FusionIO card from within the VM and it performed at speeds expected of a physical system with a series of SQLIO tests. (~40K IOPS/700MBps on random 16KB reads)
The only odd thing I see is that the card identified itself as a 320GB model insteal of a 160GB model in the VMDirectPath dialog. It's probable that this is a manufacturing mistake.
