  • Caching, tiering lead flash storage technology

    Flash management has become more important as vendors push the cost of flash down by using less expensive (and less reliable) flash media. But with so many ways to implement flash storage technology, it can be a bit overwhelming. One popular approach uses the flash storage as a cache for hot data, but there are a number of different -- yet equally beneficial -- approaches for flash caching today.

    In this three-part guide, you'll learn the pros and cons of flash caching, which stores a copy of data temporarily in NAND flash-memory chips, and flash tiering, which moves data exclusively to a flash tier, where it sits for longer periods of time. This guide on flash caching and management compares the different approaches for flash caching today, compares it with flash tiering, discusses the strengths and weaknesses of each flash storage technology approach, and more.

  • Backing up virtual machines made simple with recovery in place, VM backup software

    Server virtualization has dramatically changed the process of backing up virtual machines, as well as the options that exist for backup recovery. Perhaps the most innovative of the recovery features is recovery in place. Recovery in place allows a virtual machine (VM) to be run directly from the backup media while a traditional restoration is taking place behind the scenes. Snapshot technology ensures that the backup is not modified as a result of recovery in place and allows any newly occurring write operations to be added to the virtual machine once the restoration is complete, thereby bringing the restored VM up to date. As revolutionary as recovery in place may be, however, implementing it requires proper planning in order to avoid performance and security issues. This three-part guide will discuss how recovery in place works and what administrators must do to avoid common pitfalls. Continue Reading
