Slow processing of small files over SAN

[shawnaruch]

Hi,

I have a UCS cluster running 5.5 accessing storage on an EMC VNX. When copying large files, speed is fine. When processing small files, we're getting extremely slow processing speeds.

We've moved files around to other LUNs, moved machines between hosts and all the same.

The same workloads operate fine on physical machines with local storage.

Any thoughts as to where to look for troubleshooting?

Thanks in advance,

Shawn

Is this a block-only VNX or small files are on Celerra?

Block only VNX.
