JStor-3 IDE 8-bay RAID Array
with MDF (Multiple Drives Failure) capabilities
Dual SCSI Host Interfaces

Key Benefits
Adding another dimension to fault-tolerance, JStor III IDE 2U RAID array with MDF (Multiple Drives Failure) technology delivers reliable RAID 6 data protection combined with the high performance of Ultra160 SCSI host interface to support a wide variety of mission critical business applications. Engineered to meet stringent demands for continuous availability, JStor III IDE RAID array features a brand-new 64-bit RISC processor for blazingly fast I/O operations, ASIC assisted parity calculation, completely cableless backplane-based design, and storage capacities exceeding 2TB in a small 2U enclosure.

Low service and integration costs are assured by the JStor's cableless design, two redundant hot-swappable power supplies, turbo cooling fans, and embedded RAID controller. Three year warranty comes standard with every array and covers all components.

Versatility is in the heart of the JStor III IDE array. Indeed, it can be used as a desktop or be rackmounted into any standard 19" rack cabinet.

JStor III IDE RAID addresses many challenges present in information systems departments and delivers unparalleled storage flexibility, higher levels of data availability, management and configuration simplicity, all while securing maximum investment protection to support future growth.

Advanced Features

Exclusive MDF (Multiple Drives Failure) technology (RAID 6) provides the highest level of data protection. Multiple simultaneous drive failures can be tolerated without downtime or data loss.

Dual host connection can support two hosts simultaneously. Perfect for clustered environments, e.g. MSCS - Microsoft Cluster Server.

Full 48-bit ATA addressing standard support allows for up to 144 petabytes capacity per drive to be utilized in the RAID array.

Optional Fiber Channel host interface is available.

RAID controller provides RAID 0, 0+1, 1, 3, 5, and RAID 6, Global Hot Spare Disk, Auto Rebuild, and up to 1GB of DDR SDRAM-based data cache.

Intelligent IDE/ATA backplane design (uses no cables) allows "hot swapping" of disk canisters, power supplies, and fans for increased reliability, lower cost, and ease of maintenance.

Built-in management ethernet port provides easy access to the web-based GUI RAID Manager for configuration, management, and monitoring functions.

Completely user configurable via the front panel.
