Fully redundant and scalable
RAID Storage Systems
from Promise Technology
VTrak EClass Storage Systems
for Enterprise-SAN, FibreChannel-
and SAS IT-Environments
Two hotswap, redundant controllers
With two built in RAID controllers the VTrak dual controller
storage system easily integrates into a „No Single Point of
Failure“ (NSPOF) structure. The connections take place over
4 FibreChannel 4Gb/s channel or over 4 SASx4 interfaces.
The controller active/active modus makes sure that when one
controller fails, the other controller will take over the complete
communication – e.g. RAID and system management (Failover).
After exchanging of the defective controller unit, the system
automatically fails back into the redundant working mode
(Failback).
Up to sixteen hotswap HDD carriers
SAS or S-ATA HDDs can be used separate or simultaneous-
ly and in case of failure can be easily hot swapped. There are
12bay systems in 2U or 16bay systems in 3U available for built
into racks.

controller für SAS and/or SATA
disk drives!
As storage requirements become more de-
manding, the need for increased flexibility and
secure data access is paramount. The open
architecture of the VTrak storage systems al-
lows for the use of either SAS or SATA disk
drives in the same system. All up-to-date RAID
levels e.g. RAID 6 / 60, active/active, failover/
failback dual controller provides high availabi-
lity of the data to the users. Using Promise’s
VTrak J-Class SAS/SATA JBOD enclosures,
users can now build highly scalable, highly
available storage network which can grow
as needed. The key features of the VTrak
dual controller storage systems include:
• Redundant, hot swappable RAID
controller with active/active
Failover/Failback function
• Fibre Channel 4 Gb/s or 2 Gb/s
Serial Attached SCSI (SAS)
• Redundant, hot swappable power
supplies and fans
• 12/16 hot-swappable drive bays in a
robust 2U/3U chassis
• Flexibility to use SAS and SATA
3Gb/s drives simultaneously
• Data protection with
RAID 0, 1, 1E, 10, 5, 6, 50, 60 with
multiple global or dedicated
hot-spare drives support
• Online Capacity Expansion
• Online RAID Level Migration
• Advanced Error Handling
(Predictive Data Migration)
• Expansion with up to four 2U/3U,
12/16bay J-Class units with up to
80 HDDs as one RAID Array
• Cascadable with up to 8 E-Class SAS
systems, e.g. 8 x 80 HDDs at a single
SASx4 Bus
Two hotswap, redundant fans
The fans are located at the rear of the system and in case of fai-
lure can easily be taken out without using any additional tool.
Two hotswap, redundant power supplies
The PSUs are located at the rear of the system and in case of
failure can easily be taken out without using any additional tool.
Battery Backup Unit (BBU)
Stores the data of the controller caches minimum
72 hours after a power failure.
Cache Memory (RAM)
512 MByte RAM, upgradeable up to
2 GByte per controller unit supports
maximum performance.
