Brocade Advanced Accelerator for FICON on the Brocade 7800 Extension Switch and Brocade FX8-24 Extension Blade is qualified for extending IBM mainframe host to remote IBM TS7700 Virtualization Engine, a mainframe virtual tape solution.
Disk-based virtual tape appliances are highly adaptable systems as drop-in replacements for tape racks, and once you have a disk array many evolutionary tracks present themselves: de-duplication, virtualization, off-site-over-fibre backup, security policies and data silos for cloud architectures, scalability (both up and down), and speed increases for seek and restore.
Preserving the investment in backup policy, the DSI9003 products leverage inbuilt high speed disk to provision virtual tape drives to backup servers that are attached to an iSCSI/IP or FC storage area network (SAN).
SEPATON has announced the availability of Secure Erasure, a new option for SEPATON's S2100-ES2 data protection systems that provides guaranteed, auditable erasure of information on virtual tape cartridges.
<p>Enabling the data de-duplication function on both NetBackup 7 and Backup Exec 2010 requires only a single check mark in a pop-up box, Lodge said.<p>Both products implement the feature at three levels: Source or client de-duplication, which compresses data at the backup server; media server de-duplication, which aggregates de-duplication for numerous backups; and third-party appliance de-duplication for virtual tape libraries and other disk-based backup appliances.<p>"This gives you the ability to manage and control the backups from within the backup application, even though they're stored on a third-party device," Lodge said, pointing to appliance partners such as Quantum Corp.
New Virtual Tape Library Features Doubled Throughput and Capacity and Enhanced Software Capabilities for Greater Management and Data Protection
EMC sells two virtual tape libraries -- the DL3D 3000 and DL4000 -- that use rebranded deduplication software from Quantum and FalconStor and a disk-based backup appliance -- the Disk Library 3D 1500 -- that uses Quantum's software.
"However, the introduction of virtual tape libraries and removable hard disk drives are blurring the lines of distinction between disk and tape solutions."
A year and a half ago, the institute invested in a so-called virtual tape library made by SEPATON, which uses an integrated disk system for primary backup that allows much faster restoration of data.
Backing up to disk using virtual tape emulation or virtual tape libraries also falls short as the administration of the solution is tape-centric and schedule driven.
