Information and ideas on Dell PowerEdge rack, tower and blade server solutions.


  • MSSQL server has problems with write-caching disk controllers. Do any of the SCSI disk controllers available from Dell have this capability enabled by default?
  • The raid controller, by default, has write caching enabled. The onboard controllers do not have that capability.

  • Is the write caching specially designed for db use? Dell has standardized on SQL server. Do you guys disable write caching before installing SQL server internally?
  • I can't address what the write caching was specifically designed for but write caching is ENABLED prior to installing SQL due to the i/o performance gain.

  • On SAS 5i/R is also write cache enabled?
