I would say you could expect about 300MB/sec per engine, or up to about 1.8GB/sec.  Any workload on the box could have a big impact.
Hi,      Want to know how much time it would take for a 60TB FC-raid5 to FC-raid1.  The VMAX cache will be at 768-GB after the upgrade, enginuity at 5875.      Thanks in advance.   -Ronald
