HP LTO-4 1840 Drive Delivers Efficient Data Compression
- by Jessica McIntosh
Compression algorithms depend on redundancy. This redundancy is removed by the data encryption mechanism of HP LTO4 tape drive which efficiently scrambles the data. It is very essential that in tape based encryption the data should be compressed before the performing the data encryption. Otherwise the media cost may increase because the information will not be compressed and more tape will be required for each backup. This will result in longer tape length. HP has devised a solution to this problem which has been implemented in the 1840 LTO-4 tape drives. In HP LTO-4 tape drive, the hardware compression is implemented before the data encryption. This encryption technique used by HP 1840 tape drive increases the overall efficiency and ensures high level of data reliability.
HP LTO-4 drive's encryption mechanism does not affect the performance of backup system and tape drive. Innovative feature is added in HP 1840 tape drive that mitigates any mismatch between the backup server and tape drive's performance. When the backup sever is unable to continuously stream the information to the drive, then the drive has to stop so that it can reposition it self and then start again. This is called shoe-shining. Shoe shining is a common problem occurred in the other tape drive formats. Hewlett-Packard has developed a solution to this problem and has incorporated DRM (data rate matching) technology in LTO-4 1840 tape drive. Large buffers are incorporated in the HP 1840 tape drive which assists it to make adjustments to their internal speed and transfer speed so that they can match the host system.
DRM feature helps the HP tape drive to dynamically adjust its tape speed from 40 to 120 MB/second. HP LTO-4 drive offers superior server compatibility with all the non-HP and HP servers which includes the leading platform from Sun, IBM and Dell. Software compatibility of HP 1840 LTO-4 is also exceptional supporting the archiving & backup applications from VERITAS, Tivoli, Legato, CA, HP and many more. HP LTO4 tape drive supports the WORM tape media. This support for WORM tape media is very useful in satisfying Sarbanes-Oxley, HIPAA, SEC-17A-4 and other compliance regulations.
LTO-4 tape drives by Hewlett-Packard deliver confident data backups in severe conditions and high duty cycles. HP LTO4 drives offer more luxury and flexibility to its users that is why is HP has employed OBDR (one button disaster recovery) system. Now the data administrators can restore an entire system with the help of OBDR, and they can do this with the help of only a single tape cartridge. In case of occurrence of disaster, this OBDR technology of HP 1840 tape drive reduces the recovery time and saves cost thus helping the business to run its operations without any interruptions. New standards for durability, transfer speed and data security have been set by Hewlett-Packard LTO-4 drives. HP 1840 tape drives offer voluminous 1.6 TB recording capacity along with unparalleled levels of data security which makes it the perfect tape drive to support heavy backup duty cycles. HP LTO drive has exceptional durability and offers excellent performance.
