Figure 5-18 Advanced Screen - Closeup 5.4.1.4.1 Write-protecting Volumes Write-protecting a volume protects the data on the volume from being copied over or deleted either intentionally or by accident. On the "security" area of this screen, selecting Please set this volume to "Read-Only" adds write-protection to the volume, while selecting Do not set this volume as "Read-Only" removes write-protection. If an attempt is made to write data on a write-protected volume, the xStack Storage Array reports this attempt to the initiator requesting access to the volume and returns an error should any initiator try to write data. If the Read-Only selection is changed on this screen, the change takes effect immediately. 5.4.1.4.2 Disabling Sync Cache Commands Some applications that stream media such as video can suffer performance problems if the host file system sends the SCSI Sync Cache command repeatedly. This command tells the xStack Storage Array to write to disk all data residing in cache. If you run applications that are sensitive to the Sync Cache command, you can configure the xStack Storage Array to ignore Sync Cache commands from the host. Doing so, however, places your data at greater risk than if the Sync Cache command was not ignored. . If the Sync Cache command selection is changed, the change takes effect immediately. 64 Chapter 5 Configuring the xStack Storage Array
