Guest MT Posted August 19, 2008 Posted August 19, 2008 I'm building a new DC for our network that will replace an older machine. This machine will host FSMO,GC and DNS for the network. It's a Dell server in a RAID-1 array with a PERC 6/i SCSI controller. I've already run dcpromo on the machine and noticed the event logs warning about the write caching. This dis kcontroller does have battery backup on it so I believe I'm ok to leave this enabled? What does eveyone think in general about this? I want the the event logs clean as a whistle before I continue moving roles or at least know that I have a server in optimal condition. Should I disable write caching or not? Thanks

Guest Dusko Savatovic Posted August 21, 2008 Posted August 21, 2008 Re: Building new DC Server 2008, disk has write caching enabled. A general rule is that on any database server, write caching should be disabled. And DC role (Active Directory) stores information in a database. Otherwise you risk corruption of a database in case of power failure or some other interruption. With write caching disabled the database transactions are recorded correctly and consistently and your risk of database corruption is greatly minimized. The only exception to this rule is if you use a RAID contoller with a backup battery. This is the battery on the board itself (not to be confused with UPS). In that case, the contents of the write cache are preserved in case of power failure and written to the disk as soon as power is restored.
