Specifications

RAID

• Multiple arrays each with an independent RAID level
• Dedicated, enclosure-specific, or global hot spares.
• RAID levels: RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, and NRAID
• Online RAID level migration
• Online expansion by:
• Adding new drives
• Copying and replacing drives with drives of larger capacity
• Automatic background rebuilds.
• Independent array stripe size and write policy
• Intelligent drive handling:
• Degraded mode: skips irreparable blocks to continue rebuild
• Normal: data-block verification and repair

 Subsystem Components

• Backplane-based, cableless design
• Single-controller configuration provides full-range RAID functionalities
• Two (2) hot-swappable, redundant, 530W power supply units (PSUs)
• Two (2) redundant, dual thermal fans, cooling modules.
• One (1) optional BBU
• Sixteen (16) hot-swappable drive trays
• LCD keypad panel
