I would kindly like to ask experts here in the community to provide solution regarding storage,my question is which storage shall I go with either Dell md 3220i or IBM 3700 ISCSI SAN array.
My scenario is having 2 Dell PE R720 12 g servers with vsphere 5.5 enterprise plus licensing.Internal storage of 1.2 TB on each host.Need to scale up the storage with ISCSI SAN.I am totally confused on which one shall i select fro best performance usage and future scalability.
Thanking All Experts in Advance
For best performance usage and future scalability, go to IBM Storwize V3700.
Controller cache (remember, all your server I/O goes first to cache... more cache more performance)
Dell MD3220i: 2GB cache per controller
IBM V3700: 4GB cache per controller and can be upgraded to 8GB
Dell MD3220i: 4x1Gbps port per controller for iSCSI
IBM V3700: 2x1Gbps ethernet port per controoler for iSCSI plus 3x6Gbps SAS ports (optional 8Gbps FC port or 10Gbps for FCoE/iSCSI)
