HARD DISK MANAGEMENT
MAXX 6T employs an advanced Serial-ATA controller that manages twelve high-capacity hard disks
operating in a RAID-6 configuration. This design increases system performance, and by storing
parity data, can survive the loss of up to two drives in the array without data loss.
The Image Server brings a high level of reliability to Serial-ATA RAID through a new, switched
architecture that exceeds the reliability of SCSI shared-bus storage systems. The earlier shared-bus
architecture of SCSI had inherent performance limitations due to arbitration latency, since only one
drive may use the bus at a time. Further, a single drive failure could bring the entire storage system
down.
By contrast, the Image Server uses a non-blocking switched architecture to isolate the drives from
one another. Any drive failure makes that drive unavailable and the rest of the storage system
remains undisturbed. In addition, the Image Server uses Advanced Data Protection features, where
all drive commands are checked to ensure that no command corruption has taken place over the
entire data path.
Some of the Image Server RAID implementation features and benefits include:
• Non-blocking switch technology with RAID 6 parity
• On-board processor minimizes host CPU overhead
• Easy-to-configure arrays
• Dynamic sector repair for robust data protection
• Accelerated RAID-6 writes
• Easy, hot-swappable drive replacement from front panel
