1Labs Gallery: Dot Hill 2722 Provides Solid Storage in a Small Form Factor
by Matt Sarrel
The Dot Hill 2722 is equipped with 24 15,000-rpm SAS drives.
Here you see the 2722 from behind, with redundant power supplies and storage controllers.
Each of the two controllers is hot-swappable and contains supercapacitors and compact flash memory for cache backup.
5Diagnostic and Management Utility
The QLogic SANsurfer diagnostic and management utility displays plenty of helpful information about the attached Fibre Channel SAN.
The RAIDar management GUI opens to the System Overview page, which shows the status of various components at a glance. The menu bar running across the top (including View, Provisioning, Configuration, Tools and Wizards) puts all functions a maximum of two clicks away.
Context-sensitive help is thorough and informative.
8Rear Graphical View
The rear graphical view makes troubleshooting very easy. Here, green checks indicate that everything is operational.
9Front Graphical View
The front graphical view also aids in troubleshooting. Clicking on a disk causes an orange LED to flash on the physical drive.
