Write it on a Rock

I ran the DAOS Estimator Tool back in late January and loved the estimated savings it showed: 85.4 GB.

I held off on using it at first to see what issues others might have encountered with it and eventually began enabling a few mail databases a day over the last month or so and I've finally finished with all the mail databases.

Actual savings so far: 89.047 GB

I set DAOS up to only look at attachments over 128KB. I might cut that in half just to see how much more that would save me. I'll be sure to update when I have all the applications DAOS enabled and also if I do drop the attachment file size down.

I meant to post this back in late January when they fixed the estimator tool for iSeries but never remembered to do so. Anyway, this is the estimated savings from a production Mail/Application server running 8.5 on a i5 520 that's on V6R1.

Total Size of NSF's Examined: 216.3 GB
Total Disk Savings: 85.4 GB

Almost 40% savings (39.48% to be exact). That alone is reason enough to move to Domino 8.5 but combine that with the 28.3% we saw going from 7.x to 8.0.1 and that's a VERY compelling reason to upgrade from pre-8.0 releases to 8.5.
