Access "Virtualized servers boost iSCSI adoption"
This article is part of the Vol. 7 No. 1 March 2008 issue of Multiprotocol arrays provide NAS and SAN in a single box
The marriage of virtualized servers and iSCSI SANs is turning out to be a happy one for many users. Since VMware announced support for iSCSI SANs in June 2006, virtualization users have embraced iSCSI's lower cost and reduced complexity. Nearly two years later, the honeymoon still isn't over. Pat O'Day, chief technology officer at BlueLock, an Indianapolis-based provider of infrastructure as a service, says his young company has used only VMware and LeftHand Networks' iSCSI SANs in its two-year existence. "We were fully prepared that at some point we would have to investigate going into Fibre Channel [FC]," he says. "I still have it way out on the radar. But we're up to 50TB or 60TB now." Cost and flexibility drove BlueLock's selection of iSCSI. O'Day calls iSCSI "a very loose technology. Fibre Channel is so physically dependent on the infrastructure." iSCSI makes it easy to boot servers from BlueLock's main facility to its Salt Lake City data center, he says. iSCSI's lower cost was worth the slight performance difference. "Fibre Channel drives certainly are... 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.
