VTrak Jx30 Expansion Chassis Series

VTrak JBOD expansion systems for backup, archiving, and data centers

Reliable enterprise-level storage architecture

The VTrak Jx30 series 6G SAS subsystems delivers a high performance SAS solution with advanced enterprise level reliability and functionality. The Jx30 series offers full redundancy required for a hardened enterprise solution. Designed with high-availability in mind, the VTrak x30 series expansion chassis supports dual active-active JBOD I/O modules, allowing for redundant data paths to ensure data availability. Dual power supplies and cooling fans are in place to minimize downtime and disruption to business continuity. The VTrak Jx30 expansion chassis is available in a 3U/16-bay, 4U/24-bay or an ultra-dense 4U/60-bay.

Success Story

With the incredible amount of data generated by the fascinating research at CERN, including 25 Petabytes of data generated annually by the Large Hadron Collider, the IT team at CERN has a massive job which includes providing computing and storage capacity for processing high energy physics data. CERN IT has deployed storage solutions from PROMISE Technology, including approximately 200 PROMISE VTrak J830s storage systems which are used to help tackle the big data challenge at CERN.

6G SAS serformance

The VTrak Jx30 series allows storage applications to access their data at blistering speeds using multi-lane 6G SAS architectures. The 6G SAS connectivity paves the way for large multi-lane bandwidth to support the flood of unstructured data now flowing across networks today. Fully backward compatible with 3G SAS/SATA devices, users have the ability to deploy 3G and 6G SAS/SATA hard drives and solid-state devices (SSD) in the Jx30 series.

High-efficiency design

VTrak products utilize environmentally-friendly production methods and materials as well as a high-efficiency design that saves energy. Efficient power supplies provide up to 90% power efficiency that enables the VTrak Jx30 series to improve total cost of ownership by conserving power, reducing heat output and improving cooling costs. The internal 6G SAS expander-based architecture also allows for transparent access to each drive, enabling full utilization of the power management features built into modern hard drives.

Outstanding service and support

Every VTrak J-Class is backed by the Promise three year limited warranty, with 24/7 (Americas & EMEA) telephone and email support. In addition to our industry leading warranty, Promise offers extended warranty and on-site parts replacement options (with service levels) and response times as low as 4 hours.
