RE: [ActiveDir] Raid suggestions for DC maybe OT

[Rick Kingslan]

Dan - there will likely be as many opinions on this topic on this list as there are knots on joe's head.   Basic rules for a DC are this (IMHO):   Mirrored (or RAID1) for OS Mirrored (or RAID1) for DIT and Logs   You can certainly host a third mirrored pair for the logs, but that will mostly depend upon how BUSY your AD is and how high the replication traffic, changes, updates etc. that you experience.   If you're asking this, you most likely have a newer AD, or are re-architecting.  In either case, I'd start with the above and then monitor the performance with PerfMon.  Make some decisions on whether to ADD the third mirror based upon the I/O and performance impact of log writes vs. impact on the database reads/writes.   Hope this helps!   Rick [msft] -- Posting is provided "AS IS", and confers no rights or warranties ...       From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dan Cox Sent: Sunday, November 06, 2005 1:31 AM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Raid suggestions for DC maybe OT What would be the suggested RAID and partitioning scheme for a Domain controller.   Any suggestions are appreciated.
