Enterprise storage organizations are moving to Virtual Tape Libraries (VTL) and Wide Area File Services (WAFS) in order to meet today's challenging requirements for backup and recovery, and to enable consolidation, according to TheInfoPro (TIP). Rob Stevenson, Managing Director of Storage research at TIP, has seen the trappings of such a change on the horizon for some time, but says it has reached an inflection point.
Elaborating on findings from the most recent TIP Wave report on enterprise storage, Stevenson explained, "This is the first Wave where we are witnessing a decline in spending with enterprises' traditional backup vendors. It's not that tape is going away, but rather it is being relegated to long term archiving as a mesh of replication and synchronization policies are becoming the only methods that can meet today's challenging backup windows."
While the most recent TIP Wave is focused on a broad range of Storage Networking topics, the researchers say one of the most notable themes to arise is the increasingly universal effort to find recovery capabilities with minimal added cost. The Virtual Tape Library (VTL) appears to be benefiting most from these new demands.
"The key is that this particular technology eliminates the cost of high-performance media platforms and streamlines the backup process for certain types of data," said Stevenson.
Among large enterprises using VTL today, he said that the most frequently cited pain points include scalability -- in terms of capacity and throughput -- and integration of backup software.
Centralization is also evidenced in the study by a rise in Wide Area File Services (WAFS) implementations. This technology is allowing companies to consolidate non-centralized storage and isolated servers into centralized units.
Among the first signs of this, said Stevenson, "is the fact that WAFS are being absorbed into Recovery budgets."
Another signal: Wide Area File Service holds the #3 position among 22 different technologies on the patented TIP Technology Heat Index(TM). This index gauges the immediacy of implementation and planned spending for each of the 22 Storage Networking technologies. The full list of 22 includes technologies such as Serial ATA Drives, NAS Gateways, IP SANs, Fixed Content/Content Addressed Storage (CAS), Fabric-based Intelligence, SAS Drives, Remote Replication and Storage Security Appliances.
