Verifying Recommended Hardware Configurations

  • Article

 

It is recommended that the following hardware configurations for servers on which you deploy full-text indexes:

  • Use a mirrored redundant array of independent disks (RAID) configuration. It is recommended that you use a RAID 0+1 configuration (or RAID 1+0). RAID-5 is not recommended for full-text indexing.

  • Make sure that the disk containing the index is large enough that it has 15 percent free disk space at all times. Depending on the types of files that you store, the size of your index can range from 10 percent to 30 percent of the size of your database.

  • Add an additional 256 megabytes (MB) of RAM to the recommended configuration for a computer running Microsoft Exchange Server 2003. It is not recommended that you run full-text indexing with less than 512 MB of RAM.
