Citrix, my storage Performance Preoccupation

Hello everyone ...
Currently I have a new virtualization platform from Citrix, which consists of the following:
- Nine servers Citrix Xenserver 6.2
- 46 VMs with Citrix XenApp 6.5
- 54 Vms VDI desktop
- FC SAN Storage

Currently, Xenserver servers are in a Pool, and share 3 500GB Luns for Write Cache of XenApp and VDI Vms.
The volume was created on RAID 6, and assume that I will support approx. 48000 IOPs, required for my virtualization solution.
I've been checking the speed of access to the system disk, using the citrix perfomanceVM, and I found worrying about the graphics performance of my storage. These measurements were taken with only 4 VMs running.
Shipping graphs I took each for a one minute interval.
Could help analyze graphs, and tell me if it is really my worry valid?

Thank you all.

It's really hard to make heads or tails of what was posted.

Try this: http://bit.ly/18iwrL0

That is SQLIO, a utility that Microsoft put out to test a disk subsystem to the max.

48K IOPS sustained is going to mean a lot of HDDs probably somewhere between 350 & 480 depending on the type of disk.
Of course if you use SSDs then you only need a few to hit this number
