Using the ServeRAID GUI-Based Configuration CD



Using the ServeRAID GUI-Based Configuration CD

To start the configuration program:

  1.  Insert the ServeRAID GUI-Based CD into the  CD-ROM drive, then, turn on the server.

     One of the following screens will appear:  

  2.  Disable or Enable Read-Ahead Cache Mode:

     This choice is available in the Information mode only. When read-ahead cache  is set to Enabled  (default setting), the ServeRAID controller transfers  data from a disk to its local cache in increments equal to the stripe  unit size. This provides excellent overall performance when workloads  are steady and sequential.

     However, if the workload is random or the  system I/O requests are smaller than the stripe unit size, reading ahead  to the end of the stripe might degrade performance. When read-ahead  cache is set to Disabled , the ServeRAID controller transfers data from a  disk to local cache in increments equal to the system I/O request size,  without reading ahead to the end of the stripe.

  3.  Change the Rebuild Rate:

     This choice is available   in the Information mode only. You can select this choice to set the  priority for Rebuild operations to High  (default), Medium , or Low .
