Architectural Description
The VTrak M310p and M210p are Direct Attached Storage (DAS) subsystems.
The subsystems support 1.5 Gb/s and 3.0 Gb/s SATA disk drives:
• VTrak M310p supports up to 12 disk drives in a 2U enclosure
• VTrak M210p supports up to 8 disk drives in a 2U enclosure
All M310p and M210p enclosures include a mid-plane, RAID controller, power
and cooling units, and enclosure processor all in one cable-less chassis design.
Multiple fans and power supplies provide redundancy to ensure continued usage
during component failure. The RAID controller is hardware based and controls all
logical drive functions transparently to the host system. VTrak appears to the
computer’s operating system as a standard SCSI drive or drives.
