EVA4/8/6K as External Storage/XP BC Pair to XP array
I though best practice was to present large VDISKS from the EVA to the XP and use CVS/Volume-Management to slice the EVA large vdisk into smaller LDEVs (Open-Vs or CVs to match XP LDEVs to form BC Pairs?
We're engaging an HP Storage Consultant but he says he has not heard of such pratice and it's been always one to one. So if we've 1024 PVOLs on the XP - we'll need to also carve/slice 1024 Vdisks from the EVAs. Is this correct?
Peter M or any storage guru want to comment ad point me to that document?
Thanks.

Re: EVA4/8/6K as External Storage/XP BC Pair to XP array
Thanks but I could not find a statement in said docu about a best practice statement for EVA arrays as ES/XP BC pair to an XP as Peter Mattei mentioned:
"
Best practice of our engineers here is not to create ES volumes 1:1 but creating a larger LUN on the EVA (usually with the size of an XP internal array group for manageability) and then carve out CVS Volumes with the exact same sizes as the internal LDEVs."

Re: EVA4/8/6K as External Storage/XP BC Pair to XP array
In my opinion, the best practice for the EVA External storage is to create only one XP LDEV per EVA virtual disk and 1 virtual disk from EVA shall not be divided into the several LDEVs in the XP

Re: EVA4/8/6K as External Storage/XP BC Pair to XP array
via the following:
a) disabling the cache for external devices
b) partition cache for external devices
c) changing storage system modes
chapter 3 of the HP Storage works, XP external storage software user guide, xp 12000 disk array, etc. from above link

it is certainly the XP cache setting for the external storages which i have commented in the previous comment.
