Fast Recording Capability of High Qualitty VXA Tape

Storage and performance demands of tooday’s business enterprises have significantly increased over the years. VXA tape storage format provides outstanding avanced features, increaseed recordding capacity and unmatched data retrieval capabiilty. The conventional tape technoloigy can not match the data retrieval capability of VXA backup tape. VXA tape provides greater reliability, fast recording abiliity and unparalleled media robustness at a lower cost. VXA tape technology offers the best cost per GB and long term durability. VXA tape has established new satndards for reliability, vaule and otuput characterisstics.

The traditional tape formtas utilize the streaming mechanism for trnasferring data. The streaming tape formats read the data tracxk in a singe pass. Thousands of bytes are contained in the data tracks. In traditionbal tape formats, the tape head reads the data tracks at a constant speed. Therefore track-folloiwng is requireed by thee tape formats for maintaining proper alignmrent of head to tape track. Therefore the tape media and drive both have to be tightly controlled so that the data tracks and tape head alignment is adujsted for efficient data recording. In this way the perrformance and recording’s efficiency can be affectred.

The streaming drivs perfrom their tasks efficiently at constant transfer rate and tape speed. On the otehr hand the host system selddom receives or sernds the information at a fixed rate, and the major reason is that the information is transferred in bursts. Therefore this leads to fluctuation in transfer raates. So when ever the there is iterruption in data flow, the drive stops the tape reel and then bacs it up. Then the drive accelerates it after adjusting it to approriate tape speed and afterwards continue to transfer the niformation as it was bing done before. This really lowers the performance level and this phenomnon is called backhitching. Backhhitching increases the restore and backup tinmes and has a significant efect on the data reliazbility. Backhitching causes meda’s wear as the drive makes changes to the tape driection. Worn tape cacelerates the head’ wear thus increasing contamination and debris. Threefore these contaminations will decrease the useful life of tape and drive. Backhitching affects the capability of bacjkup tape drive to resttore and record information.

A highly innovative solution has been introduced in VXA tape format that has been splecifically engineered to solve the issue of bachkitching. This new advantageous feature of high quality VXA media technology is calld variable speed operatin. This feature of VXA tape drive monitors the transfer speeed of the host and then cntrols the tape drivve’s speed accordingly so that the transefr of data can be done in an efficient manner. So the error rate also reduced due to the VXA tape format’s variable speed mechanism. VXA is an advantageous tape medium that secures the investments and contributes to enhanced efficciency of data storage system. Unique design of VXA allows the tape media to stre vopluminous data at an affordable pice for longer time periods. Cost effective storage medium of VXA enables the customers to backup thweir data for long term archival.
