Access "Virtual tape libraries in depth"
This article is part of the Vol. 8 Num. 8 November/December 2009 issue of Hot storage trends and technology for 2010
For disk-based backup, VTLs have been a relatively easy way to replace traditional tape libraries. With added features such as deduplication, they can be an attractive alternative to other disk target systems. Virtual tape libraries (VTLs) are dead, right? Weren't they supposed to be temporary solutions that would be long forgotten once everyone started backing up to "real" disk? While that might be what the VTL naysayers had in mind, we're more than a few years into the VTL "fad" and many of the products are doing just fine. What happened was that an industry segment morphed to encompass both VTLs and intelligent disk targets (IDTs), a segment that was ultimately validated when EMC Corp. acquired Data Domain for $2.4 billion. We'll review some of the factors that led to the development of VTLs, the current state of VTL technologies and products (including the newer features they now offer), and then we'll end with a look into the future of VTLs and IDTs. Why VTLs came about The VTL/IDT market has become so overshadowed by the data deduplication craze that ... Access >>>

Hot storage technologies for 2010
In our annual assessment, we pick five technologies we think will impact your storage operations in 2010. Read how VMware backup, solid-state storage, thin provisioning, 8 Gbps Fibre Channel and data dedupe for primary storage can change how you manage storage.
Virtual tape libraries in depth
by W. Curtis Preston
Virtual tape libraries (VTLs) have been a relatively easy way to replace traditional tape libraries, but as other disk backup targets emerged, many thought VTLs would disappear. Now, with added features such as dedupe, they can be an attractive alternative to other disk target systems.
Object storage gains steam as unstructured data grows
by Beth Pariseau, News Writer
Object storage isn't a new concept in the NAS world, but some new products are bypassing traditional file system interfaces as an industry debate emerges about the best way to cope with unstructured data.

Energy conservation efforts still anemic
Our Snapshot Survey reveals that "green storage" is still not top of mind for most storage managers. Some might be willing to spend more on systems that promise energy savings, but most are still dubious.
Salaries rise as storage grows
In our exclusive annual survey charting the salaries and benefits of storage pros, many of them managed to see pay increases even as closings and layoffs sent some looking for new jobs. As data capacities grow, so does the need for dedicated storage pros.

Desktop virtualization: Better data protection?
by Lauren Whitehouse
Backing up desktop/laptop PCs has been a thorn in the side of storage managers. Virtual desktop infrastructure technology can ease the burden of data protection for PCs, but it may not be a fit for all users.
Can we survive consolidation?
Dedupe, server virtualization and data archivers are great tools to control storage capacity growth, but they treat the symptoms and don't provide true consolidation. Don't throw them out; use them better.
