Promise Technology External Storage Products
Enterprise to SMB Level VTrak E-Class and J-Class Series
VTrak 310s-Dual 2U Rackmount RAID Storage

Mfg. Model Number:
Promise VTrak VTE310sD
RoHS Compliant

Features and Benefits:
With an eye on enterprise features at a price that even a small to medium businesses can afford, the Promise VTrak E-Class fundamentally changes storage economics from purchase and set up to operation and upgrades. The flexibility to use Serial Attached SCSI (SAS) and Serial ATA (SATA) drives and the open architecture of the VTrak E-Class lets businesses use the components that are best suited to their application needs. All of the systems in the E-Class series also share the same firmware for ease of qualification. Promise's WebPAM® PROe provides an OS independent, centralized GUI for comprehensive data management.

• Supports failover/failback RAID controllers for high availability
• 12 hot-swappable drive bays in a robust 2U chassis
• Flexibility to use SAS and SATA 3Gb/s drives simultaneously
• Four 3Gb/s SAS x4 host ports for performance and connectivity
• Data protection with RAID 0/1/1E/10/5/6/50/60 with multiple global or dedicated hot-spare drives support
• JBOD expansion - up to 4 VTrak J-Class JBOD systems
• Redundant, hot-swappable power and cooling modules
• Embedded web-based management GUI via Ethernet and Command Line Interface/Utility via RJ-11 Serial Port
• LUN Mapping and Masking enable SANs and large clusters configurations
