JStor-3 SATA (Serial ATA) 8-bay RAID Array
Dual SCSI Host Interfaces

Key Benefits
JStor-3 SCSI 8 bay RAID array delivers reliable data protection combined with the blazing performance of Ultra160 SCSI to support mission critical business applications. Engineered to meet stringent demands for continuous availability, JStor SATA 8 bay RAID array features a brand-new 64-bit RISC processor for blazingly fast parity calculation and I/O operations, completely cableless backplane-based design, and storage capacities reaching 1.3TB in one small tower enclosure.

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

The JStor SATA 8bay RAID addresses many challenges present in datacenters and delivers unparalleled storage flexibility, higher levels of data availability, management and configuration simplicity, all while securing maximum investment protection to support future growth.

Drive Capacity
Drive capacities of 9.1GB (7,200 / 10,000 rpm), 18GB (10,000 / 15,000 rpm), 36GB (10,000 / 15,000 rpm), 73GB (10,000 / 15,000 rpm), and 146GB (10,000 rpm) are available.

Maximum capacity 1168GB when using 146GB drives.

Advanced Features

Exclusive RAIDm monitoring and notification software provides instant access to the status of the RAID Array and allows for 24x7 RAID monitoring and notification.

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

Up to eight low-profile Serial ATA disk drives.

RAID controller provides RAID 0, 0+1, 1, 3, and 5, Global Hot Spare Disk, Auto Rebuild, and up to 512MB of SO-DIMM SDRAM-based data cache.

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

In-band SCSI monitoring and fault notification to fax / pager or e-mail.

Completely user configurable via the front panel.

Lightweight aluminum chassis design.
