Parameter Summary Tables

This appendix lists the firmware parameter settings for Sun StorEdge 3510 FC arrays, Sun StorEdge 3511 SATA arrays, Sun StorEdge 3310 SCSI arrays, and Sun StorEdge 3320 SCSI arrays. You can fine-tune your array by making changes to these settings. It also lists the parameter defaults that you should not change unless advised to do so by technical support.

Topics covered include:


Introducing Default Parameters

Although the factory defaults provide optimized controller operation, you might want to fine-tune your array through minor modifications to the following parameters listed.

Some parameters can be changed only at the initial array configuration; other parameters can be changed at any time. Note the listing of parameters defaults that should not be changed unless directed by technical support.


Basic Default Parameters

These parameters are the primary settings for each array.
