Access "InfiniBand still a longshot for storage"
This article is part of the Vol. 7 No. 3 May 2008 issue of How to plan for a disaster before a software upgrade
Fibre Channel (FC) storage vendors see a need to play nice with Ethernet. That's why their vision of the next-generation data center includes a nascent FC over Ethernet (FCoE) standard as the key piece of what they consider a unified fabric. Such unification leaves little, if any, room for InfiniBand. The low-latency, high-bandwidth protocol isn't used much for storage, but has replaced Ethernet in many high-performance computing (HPC) environments. Its proponents say InfiniBand is a better fit for FC convergence than Ethernet. FC-centric storage networking vendors such as Brocade, Emulex and QLogic consider Ethernet compatibility the key to extending FC's life. So does Cisco Systems, which is primarily an Ethernet company, but competes with Brocade in the FC switching area. But InfiniBand vendors are working up their new standard, FC over InfiniBand (FCoIB). They point out that InfiniBand already supports 20Gb/sec with 40Gb/sec expected by next year, while Ethernet is at 10Gb/sec. And Ethernet won't be ready to run high-performance storage apps until ...

Tools to test your DR plan
by Robert L. Scheier
Periodically testing a disaster recovery (DR) plan is essential, but it can be a time-consuming and expensive task. New tools that check DR configurations and constantly monitor your site's readiness to recover from a disaster can cut costs and testing time, and provide a level of confidence that your DR plan will actually work when it's needed.
Big files create big backup issues
Big files and millions of files clogging storage systems can create big backup headaches. While there's no quick fix to the problem of big backups, there are many effective approaches, including adjustments to your backup process and newer technologies from backup vendors.

Automate storage management
by Rich Bourdeau
IT process automation tools provide workflows that can help automate manual storage management processes. The real value is when these workflow engines are integrated with storage management apps to not only guide administrators through the process, but provide them with information to make intelligent decisions and automate some of the more basic tasks.

Legal toolkit for storage systems
Storage managers may be reluctant to admit it, but they and the storage systems they manage are key players in most companies' compliance and legal readiness procedures. While ediscovery is the current buzzword, there's currently no all-encompassing ediscovery tool on the market. But you can assemble an effective toolkit with some of the point products that are available now.

Storage Bin 2.0: Virtualization: It's not just for breakfast anymore
Storage has never received the glory for all of its virtualization efforts because the server side of the shop always seemed sexier, even though forms of storage virtualization have been around for years. But server virtualization and consolidation efforts might push storage virtualization into the limelight.
Best Practices: Storage provisioning steps to keep your infrastructure healthy
To avoid inefficiency, the storage provisioning function must be brought into balance. Users must consider changes to process, responsibility and ownership, and identify areas where newer technologies can help.
