Hello!
Recently our storage (and AD) server was planned for RAID migration on storage volume for better performance benefits.
In past it was running 8 SATA drives (each 1TB) in RAID 5+0 configuration, but we wanted better write performance of the file server. The plan was to try RAID1+0 on it with up to 8x read and 4x write speed gain.
Since HP ACU was not giving an option for direct RAID 1+0 migration, I figured (and actually found some evidence of it on this boards) that RAID must be migrated first to something else, so I chose RAID5 (terrible 1x write performance, quite fast up to 7x read performance). now, the problem is that despite everything migrated correctly and initialized properly, there is still no option in ACU to migrate to anything else, except for RAID0 or RAID5 ... why is that so? how do I make it migrate to RAID 1+0? or back to 5+0 for that matter?
This machine uses Expansion Bay for more drives, the Box1 (the stock one) is full, packed with 2 SAS2 drives (RAID1 OS drive) and 6 SATA drives for storage raid, the other 2 storage drives are in expansion bay (identified in ACU as Box2) bringing it to a total of 8 drives for raid in question.
Machine is running Windows Server 2008 R2 with HP ACU 9.40.12.0, all up to date as far as I know. can double check if needed.
am I doing something wrong? any ideas please?
Thanks!
