HP Lefthand SAN and use for SQL 2012 cluster

Hello all,

 

Just if someone can advice me regarding my SQLIO results i have run from one of my WMware virtual test SQL servers to my ISCSI 64K formatted drive on the same network 10 raided Lefthand SAN. Are these results consisted with my 1GB ISCSI SAN and is it enough to support a busy SQL cluster? Thanks

there is not sufficient information provided to answer your query related to performance. However, I have attached a basic Performance guide for understanding of the environment and requirements.
