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 r

ecovery

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.

1.3

RAID

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

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 manual

ly 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 Agg

regation. All adapters simultaneously receive and transmit data.

Includes fault tolerance and load balancing. Requires a switch that supports Intel Link

-

Aggregation, Cisco Fast Ether Channel or static 802.3ad.
