Service Data
The Service Data window provides the IT administrator with the ability to collect
information about the storage subsystem, gigabit switches, or the entire system. This
information should be provided to a service technician to troubleshoot any issues with the
system. The test report is encrypted and can only be unlocked by a service technician. The
test report does not contain user account information.

Settings

To access the general configuration settings, click Settings in the left navigation panel.
These screens enable an IT administrator to modify and view general system settings for
maintenance and hardware management.

Storage Drive Caching Options

Every physical hard drive in the chassis has an on-board cache. The cache generally
improves the I/O performance of a drive by acting as a fast data buffer during large read
and write operations.
This is a chassis-wide setting, that is, all drive write-back caches are either enabled or all
are disabled.
