Hi Folks,
I'm looking at upgrading the storage array on my VM server. I run the following Build:
Dual Opteron 6338P
KGPE-D16
SAS2008 PIKE card (I have flashed these to IT mode. This one is currently in RAID mode though)
8x 10k 300GB SAS drives
256GB of DDR 3 1600
What I'm looking to do is replace the SAS drives with some SATA SSD's. I was thinking of using Samsung 860 EVO drives either 500GB or 1TB.
Due to it being PCIe 2 and the PIKE card only being a x4 link I was also thinking about getting a 1015 off ebay to use a x8 slot so I can get full 4GB/s but I couldn't find any good info on if running storage spaces in mirror mode would cause a bottleneck or in IT mode if the card can run at basically full throughput.
I'm wondering what sort of performance people see when using storage spaces in a dual mirror mode using SSD's like this or any gotcha's with taking this approach to get some better performance for the VM's as resource wise the slowest thing in the system is the disk and for the amount of SQL databases I've got with System Center its getting to be a real pain waiting for things when its pretty cheap to go SSD's now.
Any advice or input would be much appreciated.
Cheers,
