Re: XP24K and Windows Exchange 2007

Hi,
this is the doc for windows in general:
http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c01186248/c01186248.pdf

The main concern for the window platform in XP storage in general is, that it does note have the LVM (Logical volume manager).
Therefore in general the best would be if you concatenate the max numbers of the parity groups, which is 4 to have 4x(7D+1P)=28P+4D to have as much as possible disk spindles in the PG (parity group).
Then you can create better the big LDEVS across 32 striped physical disks (insted of simple 7D+1P, which is only 8 physical disks)
Other tool in XP is so called LUSE volume: Then e.g. the 100GB LDEV can be create as 4x25GB across the 4 PGs, but it is not stripped. There is a technology called Thin provisioning, which developement aims to have a disk pool with the automatic redistribution as the DG on EVA, but this is not yet developed and the current Thin provisioning version do not have such capabilities...
the pain is one part of the reality

hi,

As tested in our customer environmet, we have experienced very good performence when we created 50GB LDEVs.. LUSE was used for windows as such and the LUN size was 600 GB(50x12)with RAID 7+1. For Zoning the load was balanced across all 4 chip ports and zoning was done as Single Initiator Single Target.
