Access "New life for CDP"
This article is part of the Vol. 7 No. 1 March 2008 issue of Multiprotocol arrays provide NAS and SAN in a single box
Before data deduplication turned white hot, continuous data protection (CDP) was supposed to be the next big thing for disk-based backup. But CDP never truly caught fire with users. They liked the idea of being able to roll back to any point to restore data, but not enough to purchase and manage a standalone product to do it. However, organizations are using CDP as the underlying technology for specific applications such as Exchange, and data protection vendors are building it into their products as a feature. Now CDP is being recast from an overall backup platform to a tool to facilitate replication for disaster recovery (DR). Double-Take Software's December acquisition of early CDP player TimeSpring is the latest example of an established vendor picking up CDP to aid replication. EMC acquired Kashya and CA bought XOsoft for that reason in 2006. Backup vendors Asigra, Atempo, BakBone Software and CommVault have CDP baked into their software as a feature to facilitate DR. Symantec acquired the intellectual property of CDP pioneer Revivio in 2006, but has yet... Access >>>

Vendors retool SRM apps
by Bob Laliberte
The definition of what constitutes storage resource management (SRM) depends on who you ask and what they're selling. A recent study by the Enterprise Strategy Group queried respondents on the SRM features they use most often, their most desired features and if they would purchase an SRM product without a particular feature.

Quality Awards III: IBM and Sun shine among tape libraries
Despite their mechanical components, the reliability of tape libraries ranks high among respondents to our Diogenes Labs-Storage magazine Quality Awards. This year, IBM takes top honors in the enterprise category, while Sun reigns supreme among midrange products.
Arrays score with both file and block storage
Multiprotocol arrays that support block- and file-based storage through a single controller give users the best of both worlds: NAS for file-based information, and Fibre Channel or ISCSI block-based storage for databases and other transactional apps.

Case study: NY Mets add deduplication to roster
With an extensive lineup of corporate data, photos and video, the Mets needed to recruit some backup help. The call went out for low-cost disk backup configuration, including deduplication and compression to reduce the amount of data to be backed up, as well as WAN optimization/acceleration to speed up the replication process. After much consideration, Data Domain was drafted for the job.

Hot Spots: Tap virtual servers, storage for all they're worth
by Bob Laliberte
To keep pace with changes in the server and storage domains, organizations need to ensure that the I/O path doesn't become a bottleneck. Automated patch panels, N_Port ID Virtualization, Fibre Channel over Ethernet and InfiniBand are just some of the technologies that might resolve this issue.
