  • Software-defined technology sizzles; where's the beef?

    E-Handbook -Hyper-converged and software-defined storage are alternatives to traditional array-based storage systems. Before you junk your legacy systems, learn how these new systems are different from each other and from the storage you've grown accustomed to using.

    Products in both categories are designed to make it easier to implement new technology, usually in virtual environments. Hyper-converged systems combine storage, compute and hypervisors in one box. The bundled model makes it easier to install and manage. However, the bundled appliances do not allow you to scale those resources independently. Also, because most hyper-converged systems support only one hypervisor, that could limit flexibility. Hyper-convergence can also change the roles of administrators inside an IT team, breaking down silos. That change can be good or bad, depending on your perspective.

    Software-defined storage is an umbrella for many types of storage rather than a specific category. Common types of software-defined storage include virtual appliances and other products for virtual environments. Other applications that virtualize or manage storage across disparate hardware -- including off-the-shelf commodity systems -- also fall into the software-defined storage category. Software-defined storage can be bundled or packaged on an appliance. Buying software only adds flexibility and usually costs less than an appliance, but appliances come precertified and tested by the vendors to reduce risk.

Tiered storage from searchStorage.com

  • Flash storage caching, tiering or both? Consider the workload

    E-Handbook -If you're using a flash-based storage system, you're familiar with caching and tiering to accelerate data. Storage tiering is used in hybrid flash storage systems to separate active and inactive data. Active data is kept on the flash tier, while inactive data is moved to a less-expensive storage tier. If the data becomes "hot" once again, it is moved back to the flash tier. Because data only lives on one tier at a time, tiered architectures need to have some kind of redundancy built into them.

    In caching, data is copied or mirrored from one tier to another, so active data is on multiple tiers at the same time. If the active data is no longer needed, the cache will just create flash space for new data sets to use.

    Vendors implement tiering technology in various ways. Some even have a "flash-first" approach that puts all data on flash before it is moved to a hard disk tier to become inactive. Users therefore have to be careful not to overprovision flash in these environments.

    The decision to use tiering or caching depends on a variety of factors, such as the number of applications that require access to high-performance storage resources, the I/O patterns of these applications and your budgetary constraints.

    Learn when to use each of these technologies in your own environment.
