Poor performance using Hyper-V over SMB 3 to SOFS that front-ends SAN

-

here we're trying set up.  have new cisco ucs b200/b230 blades, blade centers, fi's.  have a pair of server 2012 scale-out fileservers on 2 of blades luns attached from our san uses hitachi ams 2500.  trying setup server 2012 hyper-v hosts, managed through vmm, use storage on scale-out fileservers on smb 3.  reason, terrible performance configuration.  example, deploying vm 50gb template takes 35 minutes going through sofs , shows throughput of around 250 mbps.  have tried following narrow down cause:

1.  took sofs out of equation , went directly san storage, , same deployment takes 8 min throughput of around 1.2 gbps.

2.  setup sofs on different hardware (ibm pizza box servers) direct attached storage, , able performance comparable saw going straight our san.

we've had cisco engineers on our configuration , don't see problems.  we've had 1 person microsoft should getting better performance front-ending our san sofs are, , based on that, opened premier support ticket microsoft, , technician told surprised getting performance "good" were, no explanation why.

our san admins saying there nothing wrong configuration, since have goes straight san performs fine (including our 100+ vmware hosts).

i'm hitting wall trying think of things @ possibly causing this.  have suggestions?

hi.

im trying understand why have opted solution. yes can simplify storage management depending on configuration. adds layer of complexity. kinda agree with vr38dett, why complicate stuff.

if take sofs out of equation, if create single file server running on ucs blade san storage. , run hyper-v on give same performance? 

1) exactly! whole idea of sofs replace expensive san / nas inexpensive x86 servers running windows , rudimentary cheap sas shared storage (or no shared storage @ if starwind powering sofss in vmware vsan style). if has fc or iscsi hardware san using power sofs block end questionable idea...

2) not same. better performance. reason: shorter i/o pipeline.
