On any server that hosts SQL Server, it is very important that the server achieve the fastest response possible from the I/O subsystem. More and faster disks or arrays provide sufficient I/O operations per second (IOPS) while maintaining low latency and queuing on all disks.

Before you deploy a new farm, it's recommended that you benchmark the I/O subsystem by using the SQLIO disk subsystem benchmark tool. For details, see SQLIO Disk Subsystem Benchmark Tool (http://go.microsoft.com/fwlink/?LinkID=105586).

 

SharePoint 2010 requires the following IOPS:

  • Crawl database, search requires from 3,500 to 7,000 I/O per second
  • Property database, search requires 2,000 IOPS.
