Deduplicating LUNs

January 18th, 2009

This is primarily focused at VMware usage, but in theory now that SnapDrive 5/6 support thin provisioning of LUNs, it could be applicable elsewhere. I’m not sure on the support / affects with any SMAI product. These are untested and I would recommend to try build this in to the demo / test lab somewhere to check how it works and any potential impact / issues.

 

DeDuplication on LUNs that have no thin provisioning will save you space in only one place, Snapshot usage (going forward that is, already existing snapshots won’t get deduplication as they are read-only).
