P2000 G3 SAS Boost Performance

I have 2x DL385 Gen7 Servers connected to a P2000 G3 SAS MSA. We have setup a raid 10 array with 14 disks (300Gb 10K Disks) just for SQL. The other disks are allocated to a number of different virtual machines.

 

Both servers are running VMWare ESXi 5.1 and boot from an SD card and do not have any internal disks.

 

We are experiencing poor performance on reading and writing to the disks from a Virtual Windows 2008 R2 SQL server. 

 

The question is would a HP PCIe IO Accelerator card http://www8.hp.com/h20195/v2/GetHTML.aspx?docname=c04110995

and how would it work? Would VMWare see the IO Accelerator as a new disk and if so would I then have to move the SQL disks to this drive? How would I then accomplish High availability in the event that host went off?

 

Any advise is appreciated.
