Hardware
Features |
• PCI-Express x8 host bus interface
• Hardware XOR engine to offload parity calculation
• Hardware RAID 6 accelerator
• Low-profile MD2 form factor
• Optional on-board battery backup unit for data retention up to 72 hours |
Supported RAID Levels |
• RAID 0 – Data striped across 1-16 drives for increased performance, but no data protection
• RAID 1 – Mirrored pair of drives for data protection with increased read performance
• RAID 1E – Data mirroring extended to maximize balanced performance. Allows odd number drive mirroring
• RAID 5 – Striped parity on 3-16 drives, ultimate data protection, capacity and performance balance
• RAID 6 – Double parity for maximum data protection on 4-16 drives; allows double drive failures without downtime or data loss
• RAID 10 – Mirrored pair of RAID 0 for double drive failure protection; can be split into two RAID 0 sets
• RAID 50 – Striped multiple RAID 5 sets to improve performance and provide additional data protection
• RAID 60 – Striped multiple RAID 6 sets to allow multiple drive failures to achieve high-data availability |
