Is your job about to change?

Actually, let me rephrase that. Is your job about to change again? I'm interested in hearing how the scope and scale of your job might be changing as storage networking evolves. Here's what I'm curious about: How will the spread of storage networking from core data centers into secondary data centers and the distributed environment change the way IT works? This is what I see happening. IP SANs and SANs-in-a-can make the technology more realistic for many more applications. At the same time, blade servers are increasingly creeping into server rooms, often packaging storage and network switches into the same frame as CPU blades. And the hoofbeats you hear coming over the horizon? That's 10Gb Ethernet, which has the potential to either replace Fibre Channel or relegate it to just high-end SANs. More to the point, it has the potential to create the option for a single unified network for both data and storage traffic. Who will be the masters of that network? So, how will IT reorganize itself to cope with these new technologies? Many...

  • Use mainframes for backups

    You can put that big iron sitting in your data center to better use by using it to back up open-systems data, too. The net effect is a streamlined backup and disaster recovery operation.

  • Any-point-in-time backups

    by  Brad O'Neill

    Continuous data protection captures changes at a file- or block-level as they happen, and provides running recovery journals for all historical data states. This shifts data protection to a more flexible any-point-in-time framework.

  • 10 basic steps for better backup

    The most evident common denominator in well-functioning backup infrastructures is effective process and control. This checklist highlights 10 areas you should focus on to build a better backup practice.

  • Make tape libraries work with all platforms

    If tape libraries could share IT resources and data across all processing platforms, data center complexity and cost could be dramatically reduced.

  • Sizing up VTLs

    Virtual tape libraries present disk as tape, so backup apps can perform backups as usual, regardless of the physical backup infrastructure. Learn about hardware and software VTLs, the benefits of each and how they might fit into your backup operation.

  • Does host-based replication still make sense?

    Host-based replication is a mature technology, but it's often not considered an option for architectures that support quick recovery. But there are many cases where a host-based option may fit.

  • VTL remedies backup woes

    VTLs remedy tape bottlenecks...

  • Cisco's switch-based backup

    Serverless backup can take the load off servers and ease network traffic. Cisco uses Xcopy on its MDS 9000 switch for serverless backup; see how it compares to other methods and products.

  • Used tape sales on the rise

    by  Alex Barrett

    Pre-used tapes are becoming a popular and inexpensive trend among IT professionals. Become familiar with the possible risks of using used tape in your environment.

  • How disk has changed backup

    Inexpensive disk has spawned a variety of disk-based backup alternatives. But with more choices comes greater complexity compared to the days when you simply had to choose a backup application and tape library. Backup guru W. Curtis Preston explains the advantages of using disk for backup, including virtual tape libraries and disk-as-disk backup targets, and discusses the pros and cons of alternative disk-based backup methods.
