Re: EMC cx400 disks & luns
We are in the same situation, looking at purchasing a CX400. My understanding of the beast is that you combine whole disks from teh array into RAID groups, and then assign a 'slice' of the raid group to be a LUN.

Steph

Second: if you have an EMC engineer, ask home/her for the information. Ours is excellent.

Re: EMC cx400 disks & luns
What you describe as "carved up into LUNs and then the LUNs mirrored" is what we at HP call Virtualization.
Virtualization actually works by allowing you to define a LUN at a RAID level, and the array applies the RAID level on the fly as you use the LUN. This allows a group of drives to have LUNs on it that use different RAID levels (RAID 1/0 and RAID 5 for example).
HP Products are currently the only ones on the market that do RAID this way - and we have 2 product lines that do it - the EVA and the VA7000 products (VA7100, VA7410).
I hope this helps - Good luck!
