> 
> Dear HP3000-L folks,
> 
> We may be purchasing a refurb VA7100 (to replace a couple of 
> Nikes that go off support on June 30 '04) this week or next, 
> and I had a couple of questions regarding what to purchase.
> 
> 1. We're hoping to get a dual-controller 7100; I've read that 
> each controller stores its own copy of the array 
> configuration, in order to be able to fail over if one 
> controller goes bad.  However, I've also read that the 3000 
> (an N4000 box) doesn't automatically fail over, so if we have 
> one controller on the array that goes bad, we'll still have 
> to unplug the FC cable from the failed controller and 
> reattach to the good controller -- kind of a 'manual 
> failover'. Is my understanding correct?  If so, is there any 
> benefit to getting two adapter cards for the e3000 box?
> 
> 2. The array comes with SDM commandview software for one 
> host. From my reading, I've discovered that either HP-UX or 
> Windows can be used to configure the array. My question is: 
> how does the configuration host access the array? Is there a 
> serial port used for configuration, or will we need a FC 
> adapter card for whatever host we use for configuration?
> 
> 3.  (ok, a 'few' questions, not a 'couple' :-)  We're 
> planning on getting nine of the 15kRPM 36GB drives. Is there 
> a 'best way' to calculate LUN size? (we're planning on using 
> RAID 1+0 and not RAID5, for performance reasons.)
> 
> I'd appreciate any insight anyone can offer. Many thanks to 
> donna for the assistance she's already provided.
