Microsoft has recently published this very useful white paper bringing best practices and guidance when sizing volumes and CHKDSK execution times: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=35A658CB-5DC7-4C46-B54C-8F3089AC097A
A few facts that caught my attentions:
- The performance gain from Server 2008 to Server 2008 R2 is huge (I can’t imagine compared to Server 2003)
- Available memory also greatly improves performance
- Turning off 8.36 name generation has a positive though limited impact on performance
- Server 2008 R2 shows more linearity in performance than Server 2008
- Running CHKDSK in read-only mode is very helpful in predicting the duration of a downtime
Definitely a must ready for Windows Admins and IT Pro’s in charge of designing file services!
