Hello all, first post.
I am currently putting together a mid to higher end box that will mainly serve as backend storage for VMWare. iSCSI or NFS will be used, I don't care which one.
My build specs will be:
Supermicro 2027R-AR24NV
Dual E5-2620 v1 (Sandy Bridge)
128-192GB of RAM
3-4 LSI SAS12GB HBAs (no expanders, straight through backplane)
25 960GB Crucial M500 SSDs (MU5 Firmware)
Dual 2 Port Intel x520 10GBe (4 total connections)
This build will be replacing a Dell r720xd due to EFI issues the Dell has, but I won't rant about that here. The Dell system was running a single LSI 9300-8i with the stock LSI based expander backplane. Hoping to improved throughput by using individual HBAs, and hoping to upgrade to SAS3 drives at some point as well. RAIDZ configuration was a 5x5 RAIDZ-1. I have no problems stepping it up to a 6X6 RAIDZ-2.
I have already tested a similar build of this setup with the Dell hardware and was able to achieve around 1.6GB/s writes and 2.1GB/s reads with dd benchmarks performed locally. Mounted VMFS volumes delivered via iSCSI (with round robin multi-path) were netting:
Not too bad, but I was looking for advice on giving it one last kick in the nuts so to speak. I was thinking a Fusion IO drive for the L2ARC and if I continue to use iSCSI, maybe a small one for the ZLOG? What do you all recommend? I would like to get the most out of this as I can. I realize the Samsung 840 EVO drives would be a better choice, however this hardware was already purchased and was handed to me to fix.
Thanks!
