We use a Clariion CX4-120 in our backup architecture and I am looking for documentation to Verify or if needed to change the configuration and make sure its optimized for backups. Could someone point me in the right direction.
From EMC Support site, you can look for CLARiiON whitepapers section, where you can find some documents related to backup.
EMC Backup and Recovery for Microsoft Applications. Deduplication Enabled by. EMC CLARiiON and Data Domain
EMC CLARiiON Backup Storage Solutions: Backup-to-Disk Guide with. IBM Tivoli Storage Manager
If you are looking anything specific, best place to look is whitepaper section of CLARiiON in EMC Support site.
Quite some time ago I had scripting in place that changed the cache settings during the backup window and change it back to normal during office hours. I only changed the page size from 8 to 16 kiB and this was purely done for accelerating the backups a bit. And it helped too! On this CX300 the backups were done about half an hour earlier than without this option set, but other than that I didn’t make any adjustments.
I can imagine when you’re using a Clariion as a backup target a lot of sequential writing will take place, so you can consider using RAID5 (8+1) for example or even RAID6 when you’re using larger drives like the 1, 2 or 3TB drives. Don’t use RAID Groups with 15 drives or so, since the chance that a full stripe write will occur will be far less than with a much smaller (8+2) configuration.
I’d look for the best practices of Flare 30 on a Clariion CX4, that’ll point you in the right direction for sure.
