Hot Spots: Step one for DR: Server virtualization

Remote replication on virtual machines adds up to a disaster recovery plan that can really work. When it comes to disaster recovery (DR), the 80/20 rule typically applies: 80% of a DR budget is allocated to 20% of the systems in the environment. While many of the applications run by organizations are business critical, often only the top tier of servers are protected by failsafe mechanisms such as clustering, synchronous replication and other continuous availability solutions. This leaves the majority of lower tier systems underinsured. Interruptions such as a server or disk failure, software fault, data corruption, computer virus, natural disaster or manmade errors can occur at any time. These interruptions affect not only the bottom line but the IT organization, which has to allocate time and resources to get the system up and running as quickly as possible. Acquiring replacement hardware, rebuilding the system and recovering data is a time-consuming process, especially if recovery is dependent on tape-based backup. Server ...

    Organizations of all sizes have adopted iSCSI because it's easy to install, inexpensive, behaves just like Ethernet and doesn't require specialized skill sets like Fibre Channel does. But do analyst claims that iSCSI performance falls short of that for Fiber Channel hold up?

  • Survey: Fibre Channel rules planned purchases

  • Automate application recovery

    by  Eric Burgener

    Today's application continuity computing (ACC) products are best suited for small- and medium-sized businesses, and are focused exclusively on Exchange, which most companies now consider a business-critical application. But the concentration on Exchange will likely change over the next few years, as several ACC vendors plan support for SQL Server and SharePoint in the future.

  • Best Practices: High hopes for thin provisioning

    Thin provisioning is a promising way to address allocation and performance. One of the biggest challenges when using the technology is knowing where your data lives, and whether it can be tracked or recovered if there's a catastrophic component failure.

  • Storage Bin 2.0: Winds of change push storage into a new era

    The transactional computing era is over. The Internet computing era is dragging data into the "cloud," and this new era will rain more files--and bigger files--down on you than you can ever imagine.
