It features both 101001000 BaseT Ethernet, 2 Gbps Fibre Channel, or iSCSI host-to-appliance interfaces, up to 290 Mbps data transfer, and 1,600 virtual tape cartridges.
Virtual Tape Library Archive System ByA VTL can complement your legacy tape archive system by introducing disk-to-disk backup time and speed advantages.
Virtual Tape Library Software Architecture AndBy emulating a physical tape library, very few changes are usually required in the backup software architecture and processes. The virtual tape library works sequentially like tape and writes data to disk in tape format. ![]() VTLs certainly can be full-fledged replacements for tape if you still want to continue to work in a tape paradigm and manage backups in a tape-job format, Boles said. A virtual tape library can deduplicate your data sets and either store the deduplicated data on tape, which means you would be able to store more data on each tape cartridge, or send the deduplicated data to an offsite location for disk-to-disk disaster recovery. Data deduplication is becoming a must-have feature in VTLs, according to many analysts. How long can a system be down before revenue loss becomes a factor How recent must your backup data be for a functional recovery. Consider how much data you will regularly backup and how long of a backup window you will have. Can you add appliances in the future to spread out the workload, or can you repurpose the unit for use in branch and remote offices as you grow. While the deduplication speeds and feeds may be impressive, how available the data is while awaiting deduplication, and how often the VTL performs deduplication may hamper your recovery goals. The type of data your VTL will see is another important factor. If you are running more than one protection program, make sure your VTL can handle multiple data formats. You have to install, configure and manage how your virtual tape library interacts with your backup software, your existing tape libraries, and your offsite replication system (if you are using replication). Youll have to implement and manage any deduplication features you install. Other things to consider include: Will you continue to use tape backup Will you deduplicate your backup data and send it offsite or put it on the tape cartridges All of these considerations can add to management complexity. Specifically, enterprise data storage and VTL vendors are making storage systems interact better with VTLs and recognize whats happening behind the VTLs so the data backup and recovery system can adapt. Then the VTLs would be helping backup systems, not burdening them. Newer VTLs are also offering network-attached storage (NAS) support to interconnect with as many network protocols as possible. Virtual Tape Library Code To IntegrateSymantec partners that join the companys Symantec Technology Enabled Program (STEP) gain access to Symantecs OpenStorage API, and can write code to integrate their technologies with Symantecs Veritas NetBackup product. Other major VTL vendors are participating in Symantecs STEP program, including FalconStor Software Inc. The following are just a few of the many VTL options available. ![]() The DL 3000 scales to 148 TB of usable capacity, includes six Gigabit Ethernet ports and four Fibre Channel ports, and moves data at up to 1.4 TB per hour.
