5.6 Controlling Host Access to the Galaxy 65’s Write-back Cache Setting

You can prevent host systems from using SCSI mode-select commands to change the Galaxy 65 Subsystem’s write-back cache setting. Some operating systems disable write cache. If cache lock is enabled, the host cannot change the cache setting. The default setting is disabled.

This option is useful in some environments where the host system disables the Galaxy 65 Subsystem’s write-back cache, resulting in degraded performance.

To lock the cache setting:

1From SAM, select Manage Galaxy 65 Subsystem > General Config > Option Configuration. The Option Configuration page displays.

2Select the Host Control of Write-back Cache option you want.

3Click Change Options.
