New Packet Technology Of Tandberg Vxa Tape Drives

Tandberg Datas award-winning technology VXA drives are more secure and easy to deal with

. VXA packet drives read and write data on the tapes using digital packets. Working of these VXA data packets is just like the data transferred through the Internet. In short, VXA is highly economical and secure tape format designed for cost effective storage and exchange of data. New Packet technology provides un-matched data transfer speed along with greater tape storage capacity. These Tandberg VXA drives are specially designed to check errors after every write and read tasks.

VXA Tandberg drives use 4-level Reed-Solomon error Correction technology. VXA-2 Tandberg tape drives have been robustly designed to extract data even from those VXA tapes whose media has been severely damaged. Tandberg drives are compatible with almost all major operating systems which include Novell Netware, MS Windows, Linux, Maces etc. These drives come with 3year limited warranty.

Exabyte and IBM VXA tape cartridges are incorporated with latest technologies which result in unparalleled performance in VXA libraries and auto-loaders. I have mentioned here some of the high speed VXA-2 data tapes that are ideal for your storage requirements: IBM VXA X-23 backup tape, VXA-2 40/80GB tape, Exabyte VXA 80/160GB tapes The respective manufacturer part numbers of these VXA tape cartridges are: 24R2137, 11100206, 11100221.

There are two different versions of VXA tapes. The VXA-V and VXA-X tape cartridges. Listed below are some part numbers of some VXA-X and VXA-V cartridges. VXA-X 80GB/160GB tape (part number 11100206), VXA-X 40GB/80GB tape (part number 11100206), VXA-V 12GB/24GB tape (part number 11100100), VXA-X 20GB/40GB tape (part number 11100106), VXA-X 33GB/36GB tape (part number 11100103).

Exabyte cleaning cartridge (part number 11100209) will be the best option for long term durability of VXA-2 tape drive. Recording capacity offered by the VXA-2 Tandberg drives is 160 GB (compressed) and 80GB (un-compressed). The tape drive reads/writes data at a rate of 6 megabytes per second to 12 megabytes per second. Helical tape drives rely on constant track angle for efficient recording while on the other hand constant tape-to-head speed is required by linear tape devices for data reliability. Tracks in the linear devices are written parallel to tape medias edge while in helical scan drives the information is recorded at an angle to the tape reels edge. Therefore In both these tape drives, there are chances that back hitching might occur. Back hitching increases the tape tension that leads to media wear.

VXA tape drive uses an innovative method in which the drive rests and enters ready-mode when the transferring of data stops. VXA-2 Tandberg drive features 4 heads and all are utilized for reading the stored data. This special mechanism assists the Tandberg drive to read the data packets during the recording process. The drive scans it multiple times. This new mechanism of VXA2 drive is called over-scanning. The over-scanning process ensures that at least once each of the data packets is read by the tape drive. Fluctuations in track pitch and track geometry does not affect the data reliability and the tape drive reads each data packet. This mechanism of Tandberg VXA-2 tape drive is very advantageous and valuable as this enables the tape drive to read the data which has been recorded by another VXA tape drive.
