VT8237

Bringing Serial ATA and RAID to the Mainstream

Unspecified 

VIA VT8237 South Bridge

1 configuration, data is copied or mirrored and stored on different disks within

the array, meaning that should a drive fail the data will still be available

somewhere else. The improved performance and fault tolerance of RAID

Level 1 are at the expense of available capacity in the drives used. For

example, if you have 2 x 60GB drives in a RAID 1 configuration, the array

size will be 60GB.

RAID Level 0+1 - RAID 0+1 provides users with the best of both worlds:

replicating the performance benefits of RAID level 0 with all the data integrity

benefits of RAID level 1. A RAID 0+1 configuration would consist of two RAID

0 disks, and a further two disks to mirror between them, meaning a minimum

of four disks is required.

JBOD - JBOD (Just a Bunch of Disks) combines multiple drives into one larger

logical one, which is recognized by the operating system as a single drive.

Although it doesn't deliver any of the performance or data integrity

advantages of RAID levels 0 and 1, it can be useful for users dealing with

extremely large file sizes such as animation and digital editing files.

VIA DriveStation™ V-RAID Controller

The advanced VIA DriveStation™ V-RAID Controller implemented in the VIA VT8237

South Bridge is the first full-featured native Serial RAID solution to be integrated into

PC chipset architecture. It enables users to benefit from all the enhanced

performance and rock solid data security benefits of a high-end RAID system, but

without the complicated setup procedures that are normally found in server and

workstation products and at a much more affordable price.

With digital media applications such as digital video creation and editing, and digital

audio storage and playback becoming increasingly popular, the demands on hard

disk drive throughput are growing at a dramatic rate. But although memory,

processor, and Front Side Bus technologies have improved in recent years,

significantly enhancing the performance of desktop systems, storage performance

has not scaled at the same rate. V-RAID overcomes this bottleneck by delivering a

significant boost in desktop storage performance.

V-RAID is the first native RAID controller to support a complete range of RAID Level

0, RAID Level 1, RAID Level 0+11, and JBOD configurations (shown in the table

below), giving the user maximum flexibility in tuning their disk array to achieve the

optimum balance of performance and data integrity depending on their

requirements.
