Some background first. This STS client has two clustered 7.0.3FP1 Domino servers running on Windows 2003 32 bit. The servers are IBM HS21 Blades with local storage for the OS and transactions logs. Domino data is stored on an IBM SAN. The client was running low on SAN storage, and hence Domino storage too. In rides DAOS to the rescue ;)
The backup cluster server was upgraded this last weekend. The production server will be upgraded in 3-6 weeks.
OK, so now the facts, figures and timelines need to upgrade a SAN based Domino server. As usual YMMV based on a multitude of variables...
Mail folder : 594G
Archive folder : 41.1G
Pre upgrade tasks to make the NSF files "pristine":
fixup : 4 hours
compact 12 hours
|Folder||Time Taken||NSF size||DAOS size||DAOS file count||Reduction|
|Archive||< 1 hour||8.7GB||7GB||18,056||61%|
As you can see, we were able to reduce SAN storage by an incredible 379GB. When we do this for both servers, well, the numbers speak for themselves.
For this specific client moving to 8.5 has a number of profound advantages:
- A new SAN can now be postponed for the foreseeable future. Given todays economic climate, that is a huge win for IT
- From a software license view point, this was free thanks to PPA.
- With this newly found space, the client is now able to do a Quickr implementation with minimal outlay costs for hardware (indeed this will only be a new blade).
Hopefully this will give you some ideas on how to address the need for DAOS to your organization.
