Nimble SAN setup with Microsoft 2012

[venky194252]

Hello Guys,

We have recently bought a new Nimble box ( We have huge NetApp SAN setup ), Its still in its testing phase, we are expecting better results since its all flash array, We are pushing the Nimble to its limits through LoginVSI tool.

Our test Setup:-

CS500 with 14 Cluster shared volumes and a quorum volume, we have created a 14 Cisco node cluster, we have created virtual machines.

Also if some one can provide all the High available testing that can be done on the storage controllers:-

1. controller failover soft and hard failure.

2. disk failure

3. SAS cable removal (IOM failure)

4. multiple disk failure ( How many we can do )

Can someone suggest the best practices for Cluster size and number of Virtual machines per cluster.

Thank you

Venkat Sudini

Hello Venkat,

The High Availability tests you are describing can be conducted, but be aware of the following.

You can pull 2 drives at the same time as you are running 2.1 code which has triple parity RAID enabled. This also means that you should be able to pull a third drive without data loss. Although this is true, the system will then decide to do a gracefull shutdown as it expects other problems to happen and wants to protect the (still) good data on the drives. You need to call support to get out of this situation.

You can also remove SSD's out of the array as long as there is still one SSD in the system you should be fine.

Pulling the SAS cable can force a failover, depending if you pull an active cable or passive.
