High
Availability
Promise VTrak E-Class is a family of intelligent,
dual controller, SAS/SATA based storage arrays that
fundamentally changes storage economics from purchase
and set up to operation and upgrades. Four 3Gb SAS
(Serial Attached SCSI) x4 host interface ports per
controller provide a reliable, high-performance
alternative to Ultra SCSI 320 storage applications.
Each standard 3U, 19" rack unit supports up
to 16 off-the-shelf 3.5" SAS or SATA 3Gb/s
drives. Attach up to four SAS JBODs to deliver 80
drive bays of direct attached storage.
Simple
and Familiar Direct Attached Storage (DAS)
Direct Attached Storage remains a favorite of SMB
operations worldwide. Easy to configure and familiar
even to novice system administrators, SAS inherits
all of the DAS attributes while leaving its limitations
far behind. With advanced multi-pathing capabilities,
cascade support and full redundancy, the VTrak E-Class
goes where parallel SCSI products cannot reach.
No Single Point of Failure
This enterprise-class, cable-less system design
includes fully redundant, hot-swappable controllers,
power and cooling units. All system components are
constantly monitored using industry standard protocols
to ensure continuous operation in case of failure
or component malfunction. Dual active-active, failover/failback
RAID controllers provide redundant data paths to
further help ensure availability.
RAID 6
RAID 6 (double parity) delivers the highest level
of reliability and data protection in a cost-effective
solution. As the capacity of storage arrays increases,
so does the risk of encountering unrecoverable read
errors with single parity RAID levels. RAID 6 can
handle double-drive failures, thereby providing
greater protection against data loss. This also
dramatically reduces the risk of catastrophic data
loss during RAID rebuilds.
Easy
to Install and Manage
The VTrak line features Promise's embedded browser-based
management interface, WebPAM PROe, eliminating the
need to install additional software. All VTrak systems
on the network can be configured and monitored using
a single, easy-to-manage interface through an out-of-band
Ethernet port. By using industry-standard management
protocols, Promise simplifies integration with third-party
management applications.
