VXA backup tape format has introduced latest features that help to increase the output level with unparalleled media durability and low cost backup operations. VXA tape technology is more efficient and durable than traditional storage tapes. The other conventional tape drives’ performance rely on geometry of the data tracks. Data track comprises of a long set of information that is recorded on the thin plastic material. Therefore in case of tape medium’s deformation the data track can easily become tilted or curved. Data track’s horizontal position along the tape edge, alignment between tape edge and data track, and straightness of data tracks are included in the geometry of recording tracks. Data read error occurs if the data track’s angle differs from the read head’s path angle or in case the data tracks is distorted. Track geometry may be changed by a number of different factors. The data tracks bend and tilt in normal storage environments because of accumulated debris, tape wear, humidity, temperature and variations in drive tension.
Stringent tolerances and design’s complexity can affect the capability of media exchange among identical tape drives. Differences in the mechanisms of tape drive can also be a factor affecting the capability of one tape drive from reading the backup media tape recorded by another drive. Over the time in traditional tape formats, the head alignment drifts which further decreases useful life and reliability of interchangeability and data restore. Manufacturers of conventional tape drives depend on increasing complex architectures to cope up with the growing demands of capacity and performance. Design of the streaming drives becomes more complex with increase in the transfer speed and track density. For solving the issues of alignment between head and tape track, the streaming media drives require high precision, costly electrical & mechanical components.

Numerous breakthrough technologies are offered by the Exabyte VXA tape storage format that is very useful in ensuring low cost backup storage with high level of media reliability. VXA tape format transforms the information into packet form and then performs the read/write operations. Data packets have proven to be one of the most affordable and reliable mechanism for transferring data. Recorded area of VXA media is scanned multiple times during data restoration. VXA tape storage drive features an innovative capability whose function is to match the transfer speed of host. This is the best solution that has solved the problem of backhitching which is a major factor that leads to wear of drive and tape along with job delays.
Simplistic design of VXA tape format makes it significantly less expensive thus making it more compelling tape storage technology. Highly reliable VXA is the first tape storage format which features three new innovative techniques OSO over scan operation, VSO variable speed operation and DPF discrete packet format. Highly efficient VXA tapes are very durable and have high resistance against humidity, extreme temperatures and work loads. Long term useful life of VXA tape cartridges secures investments and contributes to the organization’s improved overall efficiency.
Author Resource:-VXA tape format is very economical, offers faster transfer rates and superior data reliability. VXA-X and VXA-V are the two versions of VXA tape format. Tape4backup offers lifetime warranty on all IBM and Exabyte VXA tape cartridges.
