  HSTC
High Performance Virtual Tape Library.


Designed with incredible flexibility for adapting to your environment and for evolving with your growing network or enterprise, our HSTC Virtual Tape Library virtualizes extremely low cost, ultra-fast disk storage to create numerous virtual tape drives and tapes. At disk-to-disk speed, the HSTC writes in parallel, simultaneous data streams to independent virtual tape drives to deliver the fastest possible backups. Virtual backup tapes will remain cached on disk for as long as you need them - ready for near instantaneous restore.

With the HSTC’s enhanced media management features, backup and restore operations can be managed transparently across virtual tape and physical tape libraries. When working in “auto-cache mode”, virtual tapes will be written to physical tape automatically when backup software is idle, with absolutely no impact on your network or host operations. Optimizing this innovative D2D2T strategy, Cybernetics' HSTC delivers the ultimate high availability recovery solution, combining the incredible performance of disk with the cost-efficiency and portability of tape.
 
   
 
   Is the HSTC Right for You?  
 
Restore time is absolutely crucial, and immediate access to recent backup copies is of utmost importance, but your budget won't permit a multi-drive performance tape library. The HSTC can emulate a tape library to store backup sets for any number of days or weeks live on disk for the fastest possible backup and restore time. You can selectively choose the virtual tapes you want to archive, and Offload them to your existing tape drive with no additional cost for tapes, software, drives or libraries.
Uptime on your production servers is too critical for the cumbersome burden of the direct attached tape drives that may lock up your servers with a SCSI bus glitch. The HSTC can attach directly to your Ethernet network, accessible via iSCSI to all compatible host systems on your network. The virtual tape drives appear just as locally attached SCSI tape drives, allowing independent, simultaneous backup of multiple servers. Your existing SCSI tape drives connect directly to the HSTC for archiving to physical tape.
You have legacy host systems that are not networked with your newer open systems, locking you into maintaining multiple backup drives. The HSTC can connect to the SCSI tape controller on your legacy host, as well as to your Ethernet network. Your legacy host can write a local SCSI backup to one virtual tape drive at the same time that your Wintel and Lintel hosts write backups to other virtual drives via iSCSI. Your legacy SCSI tape drive connects to the HSTC and the Offload feature archives to physical tape at your convenience.
You need to add disk storage and upgrade your backup solution, but your budget won't cover both. Most HSTC models can be configured for direct host attachment of one RAID set for storage, with a separate RAID set for the virtual tape backup functions. You can use one RAID disk subsystem to increase both the speed and capacity of your backup, as well as increase your disk storage speed and capacity.
You are responsible for maintaining a comprehensive, enterprise-wide backup plan, but you also have a number of users who need the ability to directly backup and restore user data files. The HSTC can be attached directly to your Ethernet network and configured with multiple virtual tape drives and tapes that are directly accessible over the network from any number of servers and workstations over the network. Users can pick a virtual tape and load it into a virtual tape drive to backup and restore at will. Other virtual tape drives and tapes are concurrently available for your centralized backup requirements.
Your disaster recovery plan requires immediate availability of backup copies as well as duplicate off-site tape copies for Ethernet networked buildings spread across the corporate campus.  From any campus location, the HSTC can connect to the Ethernet network and backup data from all remote facilities. The HSTC Offload feature can then be used to archive to both a locally attached SCSI tape drive, and an iSCSI tape drive located in a remote building.
None of your branch locations scattered across the country employ IT staff, and you are responsible for maintaining secure backup copies at headquarters. From headquarters, the HSTC can present multiple virtual tape drives such that data coming in from various locations over T1 can be written to virtual tape drives and tapes. The disk-based virtual tape drives can accept the slower T1 transmissions that would destroy a tape drive with excessive repositioning, and then archive to a locally attached tape drive at maximum speed.
Your DAT drives simply cannot keep up with your server backup requirements, but you have a large inventory of legacy tapes locking you into the format. The HSTC can connect to the SCSI tape controller on your server, and appearing to your existing backup software exactly as your DAT tape drive, write many virtual DAT tapes onto disk at maximum speed. Your SCSI tape drive connects to the HSTC and the Offload feature archives the virtual DAT tapes to physical DAT tapes at your convenience.
You have a high-speed tape drive, but your legacy hosts stream data so slowly that you do not realize the speed advantage, and repositioning is wearing on your expensive new tape drive. You can stage all of your backups to the HSTC via SCSI and/or iSCSI. With your high speed SCSI tape drive connected directly to the HSTC, the Offload feature will stream the data to tape at maximum speed minimizing the time it takes to write to tape and eliminating repositioning wear and tear on the tape drive.
