We are planning to implement SAN infrastructure that will be the base of server consolidation via vmware . All our production mission critical apps like exchange , sql server ,domian controller etc will be running as a VM and we need a strong SAN inforastructre. We are SMB so we cannot afford big solutions like EMC or netapp. What do you think about HP Lefthand NSM series solution and its performance ?. Will it provide what we are trying to achieve here?. Has any one using it now?
