The deal about SVC
> What's the deal about SVC?
Well, the deal is you can take a truckload of 'el cheapo' arrays, plug them almost braindead into a SAN and still get away with it since the SVC will provide all the management and redunancy to place enterprise workloads onto them.
Persistent rumor claims there are shops out there which have a pair of DS6k high performance/pricetag arrays and around two dozen of HP MSA2212/2312 (and a bunch of other stuff) arrays spread evenly across two datacenters quite some miles apart.
If you´d plug all those into an SVC cluster you´d be able to mirror drives without OS interaction, could evacuate arrays going down for maintenance and move demanding workloads temporarily (or permanent) onto the expensive storage without the clients ever noticing.
Well, the users call when their jobs suddenly run in 1/4th of their previous runtime. And then they call again when I move^H^H^H^Hwould move them back onto the MSA... ;)
Really unscrupolus Sysadmins woud even run Raid accross several cheap boxes and get amazing performance out of dirt-cheap arrays.
Even with the SVC licenses for far less than proper arrays would cost.
