Highlights

• SCSI-320 to SATA-II single controller RAID subsystem
• Hardware XOR engine by dedicated ASIC chipsets
• Tower or desktop stackable enclosures
• Dual-speed fans to reduce noise
• Dual Power Supplies
• 8 Hot swappable drives, Up to 4TB capacity
• Supported drives: 250GB SATA and 500GB SATA

RAID

• Multiple arrays configurable with dedicated or global hot spares
• RAID levels supported: RAID 0,1,3,5,10,30,50
• Online expansion by: Adding new drives, Copying and replacing drives with drives of larger capacity
• Automatic background rebuilds
• Configurable stripe size and write policy per array
• Intelligent drive handling: In degraded mode: skips irreparable blocks to continue rebuild, In normal operation: data-block verification and repair

Host Interface

• Two (2) SCSI-320 channel through two (2) VHDCI 68-pin SCSI ports; SCSI-160 backward compatible
• Concurrent I/O commands
• Tagged command queuing up to 256
• Variable stripe size per logical drive
• Optimisation setting for random or sequential I/O’s 

Drive Interface

• Eight (8) 3Gbps SATA-2, hot swappable drive trays that accommodate 1-inch pitch, 3.5-inch SATA-1 or SATA-2 disk drives
• Automatic bad-sector reassignment
• Dedicated bandwidth to each connected drive

Management

• Front LCD Control panel for set-up and configuration
• 10/100 BaseT Ethernet for out-of-band management
• One (1) RS-232C serial port for local access to firmware embedded utility
• VT-100 terminal emulation via RS-232C
• Telnet access via onboard Ethernet port

Indicators

• RAID controller module
• Cooling Module
• Power Supply Unit
• Hard Drive
• Violated temperature thresholds
• Module status LED indicators: 2 per drive tray, 1 per cooling module, 1 per power supply unit, 3 per LCD panel, 4 per RAID controller module, 2 per Ethernet port

Intelligent Drive Handling

• If two bad blocks occur on two member drives of an array, the integrity of the stored data is endangered. 
• Media Scan handles low quality drives in both the degraded mode and during the rebuild process.
• For additional data security, other intelligent drive management features include the transparent resetting of hung hard drives, power-failure management, and bad drive handling during LD expansion.
