Installing Physical Drives
If your VTrak subsystem shipped with the drives installed at the factory, you can
skip this section and go to “Making Management and Data Connections” on
page 25.
The VTrak Ex30 RAID subsystems and JBOD expansion units support:
• SAS and SATA physical drives
• 2.5-inch and 3.5-inch physical drives
• Hard disk drives (HDD) and solid state drives (SSD)
