Anybody have experience with running diskeeper on a W3K BES (for Domino)? I had good experience with using this product on a Domino w2k mailserver. If not what do you use for defragmentation (if anything)?

Every month during our maintenance window I take down BES and defrag the entire BES\state directory. My disk queue length then drops from ~3 to ~1 for the next few weeks until it creeps up again.

When we upgrade to 2003 I want to use the built in defragmenter & schedule it. Between that & pagedefrag set to run at every boot, I don't think I need the extras of diskkeeper.

I use Diskeeper 9.0 on all our servers, and the BES gets done every few weeks. It can get badly fragged, but the best update was done via the DK admin menu, when I got warned teh MFT table was almost full (this happens on a lot of systems, desktops & latops too). Once we let DK increase the MFT and defrag the system, it was running better than ever, with email landing on the handsets, some 30 - 40 sec before the Exchange 2003 server had copied it to the users mailbox.

Don't discount Diskeeper until you have seen its full power. The in-built defragger though, is basic at best.
