RAID

• Hardware RAID5 & RAID6
• Supports RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, and NRAID
• RAID Migration
• Configurable stripe size and write policy per logical drive
• Multiple Global, Dedicated, & Enclosure-specific hot-spares
• Intelligent Drive Handling:
  • In degraded mode: skips irreparable blocks to continue rebuild
  • In normal operation: data-block verification and repair

Host Interface

• Eight (8-R1430) or four (4-G1430) 4G FC
• 4Gb/s via short-/long-wavelength LC-type SFP
• Concurrent I/O commands
• Tagged command queuing up to 1024 Max
• command queue up to 1024
• Fault-tolerant host links via onboard bypass

Drive Interface

• Sixteen (16) 3.0Gbps SAS, hot-swappable drive trays
• Accommodates 1-inch pitch, 3.5-inch SAS or SATA-II disk drives
• S.M.A.R.T. and NCQ support
• Automatic bad-sector reassignment
• Dedicated bandwidth to each connected drive

System Components

• Heavy duty 3U enclosure
• Dual- (R1430) or Single (G1430) RAID and I/O management controller module
• Fault-tolerant modules interfaced through a common backplane
• High availability SAS domains to hard drives via expanders and port selectors
• One (1) 512MB DDR DIMM module (default, supports up to 2GB in size)

• COM2 for UPS connection
• GUI, Telnet, and SSH system monitoring via Ethernet
• Browser-based or Java-based RAIDWatch manager software
• Firmware-embedded manager via RS-232C (audio jack) that is platform independent
• Widest range of event notification methods including email, LAN broadcast, fax, SNMP traps, SMS, and MSN
• LCD keypad panel to all configuration options
• Event log in reserved space; Administrator's activity log
