JStor-4 SATA 2U with MDF
|
|
|
Exclusive MDF (Multiple Drives Failure) capabilities (RAID 6) provides the highest level of data protection. Multiple simultaneous drive failures can be tolerated without downtime or data loss.
Array Roaming feature gives administrators the ability to move a complete raid set to another system without losing RAID configuration and data on that raid set.
Redundant Flash Image provides an extra layer of protection against the firmware image corruption. If the primary firmware of the RAID controller becomes corrupted, the secondary firmware image will automatically be used.
Full 48-bit ATA addressing standard support allows for up to 144 petabytes capacity per drive to be utilized in the RAID array.
ASIC assisted parity for lightning-fast throughput.
SNMP supported.
RAID controller provides RAID 0, 0+1, 1, 3, 5, and RAID 6, Global Hot Spare Disk, Auto Rebuild, and up to 1GB of DDR ECC SDRAM-based data cache.
Intelligent IDE/ATA backplane design (uses no cables) allows "hot swapping" of disk canisters, power supplies, and fans for increased reliability, lower cost, and ease of maintenance.
Built-in management ethernet port provides easy access to the web-based GUI RAID Manager for configuration, management, and monitoring functions. E-mail event notification built in.
Completely user configurable via the front panel.
Online Parity Consistency verification feature insures RAID set integrity.
