Component Summary
Compaq has enhanced the StorageWorks Enterprise Backup Solution (EBS) with support for a
larger Tape Library called the Compaq StorageWorks TL895 DLT Tape Library. The TL895
supports up to seven DLT 35/70 tape drives and up to ninety-six data cartridges for a
compressed capacity of 6.6 TB. The TL895 is a vast improvement in performance and capacity
over the current Compaq DLT 15 Cartridge Library Model 35/70 that has fifteen cartridges.
Combining the high-powered TL895 DLT library with the functionality of the Enterprise
Backup Solution (EBS) makes data management:
■
Easier through centralization.
■
Faster through multiple backup and restores concurrently executing on all seven drives.
■
Scaleable because two to seven drive configurations allow sizing both speed and volume
to meet individual enterprise data zone needs.
The Enterprise Backup Solution
After examining a broad range of technologies, Compaq developed the Enterprise Network
Storage Architecture (ENSA) to take customers well into the 21
st
century. Working closely with
industry-leading independent software vendors (ISVs), Compaq created a fully integrated and
seamless solution--the Compaq StorageWorks Enterprise Backup Solution (EBS). This solution
consists of the following:
■
An independent Fibre Channel loop capable of transferring data at 100 Megabytes per
second (MB/s).
■
Fibre Channel Host Controllers and a Fibre Channel Storage Hub 12, linking the
server to the Fibre Channel loop.
■
Fibre Channel Tape Controllers (FCTCs) that convert Fibre Channel Protocol to
Differential SCSI protocol for the tape libraries. The FCTC also allows autonomous
control of the tape unit.
■
The Compaq StorageWorks TL895 DLT Tape Library with seven DLT drives and up
to 6.6 TB of storage.
■
Storage management software that takes advantage of the added bandwidth of Fibre
Channel and allows multiple servers to access multiple tape drives simultaneously.
