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).

Data Deduplication and Read Ahead Cache

January 18th, 2009

This has been discussed quite a lot, but I thought I’d throw in my 2 cents. A lot of people are still new to de-duplication and what it does, and a lot of people are still very nervous of using it in production. I’m still hesitant, I’m waiting for “2.0” in the dedupe world, as ever I’m rarely at the bleeding edge with technology as it scares me too much and I’ve seen too many people lose large amounts of data by going bleeding edge.
