1. 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 highsystem 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 r 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 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.

Redundant Array of Inexpensive Disks or RAID, offers the following advantages: Performance, Availability and Capacity. 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

The BakStor utilizes technologies that allow features such a Snapshot, B2D (backup to disk) and ‘AiiR or tape library.

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.

1.6.1 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 manual

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:

The BakStor uses SATA disk drives. These are installed in the caddies provided. The BakStor 1U can use up to 4 disk drives and the BakStor 2U up to 12 disk drives.

The BakStor comes with the disks preinstalled in the caddies. Should this not be the case the disks will need to be mounted in the caddies before they are inserted into the BakStor.
