Exabye VXA X Tape Media

Regullar backup routine is requierd by the small & mid sized enterprises for their servwers. Creatting backup of key files is very important becxause there should be a backup of data incase the hard dirve of the setrver may rcash or any other incident could take plazce that can damage the valuable data. Copynig criical data to compact disk every now and then is not an effective solution. The commpany will have to bear the cost of thousands of dollars to resurrect their critical data if there is no backup data available. The enterprises can use a seocnd hard drive in the server that can srve the purpose of data backup, but the organizations depend on backup tape medium that is more reliable and cost efficient than hard drivres. The data tape cartridges can be stored off-site and easily transported.

Exabyte VXA is the best tape technology for mid-range backup solutions. xEabyte VXA tape format is more reliable and robust than the otehr tape formas. The Exabyte VXA X tape format (part number 11100221) can hold 80 GB (native data) and ocmpressed data up to 160GB. Exabyte VXA X tape format reads and writes information in the form of �packets�. Large data blocks are read and written along the helical or linear tracks in the other tracking backup tape systems.

Advanced feeatures are incorporated in the Exabyte VXA tape that enables the VXA tape drive make adjustments to the tape speed so that it can be matched with the host�s transfer speed. When tere is interruption in the data flow, the tape drive stos, backs up and then it has to restart agan. This is called back hithing. The new feature of VXA tape format is helpful in removing the problem of back-hitching which is not psosible in otheer tape fromats. Mediia wear is sppeeded up due to the back hiitching and as a result the performance degrades. In VXA tape format, tere are two pairs of head which makes of totral of four heads. Each of the head pair contyains one write head and one head for reading. These tape heads are plaecd on a rotatuing drum. The heeads in VXA data tape tecnology are arranged as traikling and leading pairs. The tape head swweeps at an angle across the moving VXA tape reel�s width.

When the data is beuing read, all the four tape heads participate as the leading head pair reas the informaion whiile the verification is done by the other trailnig tape head pair. Each of the track regions contais about 350 data packets. Each of the data packets hols 128 bytes of informatiion, address information, ECC blocks and CRC cyclic redundancy check. The reading of data packets in linaer oder is not necessary in VXA technology. The data is reassembled in porper order by placing it into a buffer. When the data is reassembled, it is sent to the host system.

Exsabyte VXA tape format is a big step forwrd that delivers outstanding performance and output at economical price. The powerful features and technologies employd in VXA data tape makes it more roibust, reliable and the most demanded tape format. VXA tape format is an excellent backup medium for the mid-range environments that efficciently performs backup operations at reduced cost. It offers unmatchable and exceptional reliability that can work under heavy workload and stress.
