Windows NT Server and Multi Disk Defrag

By GemStone ·
I am seeking a reliable Disk Defragmentation utility to use on a Windows NT 4.0 production server that has a RAID 5 controller (disk stripping) and 5 hot swap hard disks online with one hot spare. The server box is an HP Netserver LCII. Will any defragmentation utility work with RAID5? Have you experienced a reliable defrag utility?

O&O Defrag is made by a German firm and is EXTREMELY reliable, but I have not personally seen it used on a RAID setup.

These guys are awesome and have come a LONGGGG way in the last two years. Their tech support is some of the best I've seen. Again, I've not seen it used it a RAID setup so you may want to ask about it.

Diskeeper from Executive Software is the one to use. A light version of Diskeeper was included in Windows 2000.

Did not express any experience using Disk Keeper in a RAID setup.

There are several 3rd party commercial defraggers available:

PerfectDisk 2000 - www.raxco.com - Schedulable, defragments pagefile, directories and MFT and is the
only commercial defragger capable of defragmenting the rest of the NTFS
metadata.PD2k runs on Win9x/WinMe/NT4.0/
Win2k. From a central point you can schedule defrag activity throughout. No difference in functionality between the workstation and server version. PD2k is a "one pass" defragger - designed to
do the job in one pass.

Diskeeper - www.execsoft.com - Schedulable, defragments pagefile directories and MFT but is unable to defragment the rest of the NTFS metadata. DK runs on Win9x/NT/4.0/Win2k. Requires their Server version if you want to schedule defrag activity through the network. May require more than one pass to completely defrag a partition.

O&O Defrag - www.oo-defrag.com. Schedulable, defragments pagefile and MFT
but doesn't defragment the rest of the NTFS metadata. You have to purchase
their "Network Addition" which allows you to schedule through the network.
O&O Defrag is a "one pass" defragger - designed to do the job in one pass.

Speedisk 5.1 - www.symantec.com. Schedulable, defragments pagefile
directories and MFT but is unable to
defragment the rest of the NTFS metadata. Requires purchase of their Norton System Center if you want to schedule
defrag activity through the network. SD is a "one pass" defragger -
designed to do the job in one pass.

OnTrack's Suite - www.ontrack.com. A suite of products. You can't just buy
the defragger. Schedulable. Works on NT 4 and Win2k. Don't know too much
more about this one.

Hope this helps!

The detailed information about various vendor defrag utilities is terrific. Do you know if these utilities will cause data corruption in a RAID5 environment?
