EMC VNX/Unity Storage for Solaris Cluster 4.3, how many nodes in the cluster is allowed ?

Hi Everyone,

Recently we installed EMC Unity650F flash storage, and it would provision LUNs for our Solaris server, which is configured with Solaris Cluster 4.3. In this cluster, there are 8 nodes (8 virtual machines, which reside in 2 physical machines).

We created clustered UFS filesystem from the LUNs provisioned by the EMC flash storage, but we noticed that the filesystem's performance (IOPS and I/O throughput, etc.) is very bad.

I noticed this document "ORACLE SOLARIS CLUSTER INTEROPERABILITY MATRIX", which is regarding technical facts how EMC storage interacts with Solaris Cluster 4.3:

http://www.oracle.com/technetwork/server-storage/solaris-cluster/emc-vnx-matrix-4x-1652575.pdf

First off, I noticed that Unity650F is not in the list. I think there is a possibility that since it's a new model, it might not be immediately reflected in the document yet. I will double check with EMC engineer.

But what really confused me is this column "Maximum Number Of Nodes", which is 6 in the document. Here if this value means the total number of nodes in a Solaris Cluster (v4.3), which the EMC storage could inter-operate with, this number sounds too small.

I am curious what's the exact meaning of "Maximum Number Of Nodes" in the document ?

I really appreciate your prompt reply !
