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.

Choosing the right RAID level allows for the desired combination of performance, availability, capacity and fault tolerance. The BakStor supports RAID levels 0, 1, 5, 1 + Hot Spare, 5 + Hot Spare. Fault tolerance features such as allocated hot spare drive enables a high tolerance level of RAID disk drive security and safety. 1.4 Backup The BakStor utilizes technologies that allow features such a Snapshot, B2D (backup to disk) and `AiiR' technologies. There is an external port option to allow backup to an external tape device or tape library. 1.5 User-Friendly Configuration There is a comprehensive menu system that can be accessed via a standard browser using the http protocol. The menu system allows all areas of the BakStor to be controlled, changed and managed. 1.6 Fault Tolerance 1.6.1 Disk Drive The BakStor has comprehensive drive failure management that allows automatic RAID rebuilding (RAID levels 1 and 5 only) using an allocated hot spare drive in the case of a disk drive failure. The RAID automatically disconnects the failed drive and rebuilds data onto the hot spare drive, which in turn replaces the defective drive after the rebuild process. A failed disk drive in a RAID can be replaced manually followed by a background rebuilding of data. 1.6.2 Connection The BakStor uses standard 1-gigabit Ethernet connections. Using the second Ethernet connection the network can be configured in three different fault tolerant options: AFT - Adapter Fault Tolerance. Only one network adapter is active at a time. On any failure of primary connection (cable, adapter, port) a secondary adapter automatically takes over. ALB - Adaptive Load Balancing. Transmission load is shared among all adapters 802.3ad -Intel Link Aggregation. All adapters simultaneously receive and transmit data. Includes fault tolerance and load balancing. Requires a switch that supports Intel LinkAggregation, Cisco Fast Ether Channel or static 802.3ad.
