We recently purchased an MD3220i SAN for use with our ERP system however we've found we're not getting the performance we need (Using SQLIO random write test we're getting about 2100 IOPS and 130mb/s. We're also getting fairly high latency between 5ms and 8ms)
Is it possible to upgrade this device to use another connection method such as 10GB iSCSI, FC or Direct SAS to the host or would that require a new enclosure?
