Sepaton boosts VTL integration with TSM and Symantec

Backup target device supplier Sepaton has upgraded the software on its S2100-E3 2925 virtual tape library (VTL) to version 7.1. It has extended support to Symantec NetBackup OpenStorage (OST) over Fibre Channel and enabled better integration with the IBM Tivoli Storage Manager (TSM) backup product via Gresham software.

The Sepaton S2100-E3 2925 – launched in March – VTL comprises nodes built on HP servers with Sepaton’s S2100 software, plus disk shelves that scale from 20TB up to more than 2PB using 2TB Fibre Channel drives. Throughput ranges from 10TB/hour for one node up to 80TB/hour for an eight-node configuration.

Data deduplication is neither inline nor post-process but is, according to Sepaton, “concurrent”, with processing at the target taking place as soon as a 50GB tape cartridge’s worth of data is ingested.

The 2925 already had integration with Symantec OST over IP, IBM TSM, EMC Networker and HP Data Protector. Now it has added support for Symantec NetBackup OST over Fibre Channel and for Gresham Enterprise DistribuTape (EDT) version 10. This allows users to configure and manage IBM TSM tape environments via automated recognition of Sepaton hardware from the Gresham software.

Eric Silva, director of marketing with Sepaton, said: “Integration with Gresham DistribuTape virtualises large IBM TSM environments – such as tape, disk, management servers – by automating the TSM virtual tape drive device discovery, definition and volume and labelling processes. This now takes minutes via Gresham where previously it took maybe a whole day.”

The Sepaton 2925 VTL is a data deduplicating target disk backup device that uses disk to emulate tape cartridges for devices that can write to it via a variety of backup products, so making it suited to large, heterogeneous, datacentre environments.

It is aimed at an enterprise market where tape is still prevalent, but allows data to be staged to disk before moving off to tape. It competes with the like of EMC’s Data Domain hardware, which also incorporates target data deduplication.

Such high-end backup disk hardware is in contrast to the backup appliances found in the mid-range where suppliers bundle disk capacity with inbuilt backup software installations. These products are more popular with smaller organisations that possibly lack in-house IT skills and prefer to have popular backup applications in a preconfigured box.
