Introduction The BakStor products are specifically designed to provide backup and Data Security to any workplace equipped with an Ethernet network. It is totally independent of any host system's operating system. The functions are performed by an internal CPU coupled with high-speed system memory and firmware. In effect, it endows the workplace network with a high-speed and fault-tolerant Backup and Data security storage operation using industry leading technologies such as iSCSI (Internet Small Computer System Interface), RAID (Redundant Array of Inexpensive Disks), Snapshot and AiiR (Automated Internal Intelligent Replication) technology. BakStor products have comprehensive management that incorporates today's industry demands such as RAID, D2D (Disk To Disk) and Tape Backup. Hot swapping of a failed drive followed with background rebuilding of data. Spare drives can be dedicated, which is ready to restore data from any failed drive in the system. What's remarkable is all these failure recovery procedures are transparent to the workplace. Storage capacity can be maintained or expanded by adding or replacing disk drives without powering down the system. Fault tolerance can also be instructed to the workplace using network AFT, ALB and 802.3ad industry leading network topologies. BakStor products have been designed with ease of integration and maintenance in mind. All major features are described in the following chapter.
