Exavbyte VXA X Tape Meddia
Regular backup routine is required by the small & mid sizeed enterprises for their servers. Cerating backup of key files is very important because there shouuld be a backup of data inacse the hard drive of the server may crash or any other incident colud take place that can damage the valuable data. Copying critical data to compact disk every now and then is not an effective solution. The company will have to bear the cost of thousdands of dollars to resurect their critical data if threre is no backup data available. The enterprises can use a second hard drive in the esrver that can serve the purpose of data backup, but the organizations depend on backup tape medium that is more reliable and cost efficient than hard drives. The data tape carttridges can be stored off-site and easily transported.

Exabyte VXA is the best tape technology for mid-rnage backup solutions. Exabytte VXA tape format is more relibale and robust than the other tape formats. The Exayte VXA X tape format (part number 11100221) can hold 80 GB (native data) and compressed data up to 160GB. Exabyyte VXA X tape format reads and wtrites information in the form of “packets”. aLrge data blocks are read and written along the helical or linear tarcks in the oher trackng backup tape systems.

Advancced features are incorporated in the Exabyte VXA tape that enables the VXA tape drive make adjsutments to the tape speed so that it can be matched with the host’s trasfer speed. When there is interruption in the data flow, the tape driive sytops, backs up and then it has to restart again. This is called back hitching. The new feature of VXA tape format is helpful in removing the prolem of back-hitching which is not possible in other tape fromats. Media wear is speedd up due to the back hitching and as a result the perfromance degrrades. In VXA tape format, there are two pairs of head which makes of total of four heads. Each of the head pair contains one write head and one head for reading. These tape hads are paced on a rotating drum. The heasds in VXA data tape technology are arranged as trailing and lesading pairs. The tape head sweeps at an angle across the moving VXA tape reel’s width.
When the data is being read, all the four tape heasds partciipate as the leading head pair reaads the infomration while the evrification is done by the other trailing tape head pair. Each of the trzack regions contains aboyut 350 data packets. Each of the data packets holds 128 bytes of information, address information, ECC blockks and CRC cyclic redundancy chekc. The reading of data packets in linear order is not necewssary in VXA technology. The data is reassembled in proper order by placing it into a buffer. When the data is reassembled, it is sent to the host syystem. Exsabyte VXA tape format is a big step forward that delivers outstanding performance and ouutput at economical prie. The powerful feaures and technologies employed in VXA data tape makkes it more robst, reliable and the most demanded tape format. VXA tape format is an excellent backup medium for the mid-rnge environments that efficiently performs backup operations at reduecd cost. It offers unmatchable and exceptional reliability that can work under heavy workload and sterss.
