MD1000 Redundant EMM ?
I'm trying to figure out what the benefit is of having a redundant EMM in an MD1000 storage array. The documentation says the redundant EMM will maintain enclosure functions ... but if the primary EMM fails, and that is what connects the MD1000 to the PERC5 card in a server, how is it still connected? Can the primary EMM "fail" and still provide electrical connectivity to the RAID controller? The MD3000 is probably the product I want to consider for redundancy and clustering options but I'm just trying to make sense of the MD1000 "redundancy". Thanks, Dave

If an EMM fails then the surviving EMM then assumes enclosure management, which includes monitoring and control of the audible alarm, enclosure LEDs, power supply/cooling fan modules, and fans.
Failover does not include providing connectivity to the drives controlled by the failed EMM

Right, so what good is it to have something in the storage array maintaining management and monitoring functions of the storage array if my server can't access the drives?
