  • Buyer's checklist to the hyper-converged market

    As the hype around the hyper-converged market persists, more storage administrators are evaluating the systems to determine whether they truly provide cost savings, simplified management and easy scalability. But to make that determination, there's a lot to consider. The first step is determining whether the type of data and business processes used in the environment are suitable to a hyper-converged environment. A virtual desktop infrastructure, for example, is a prime use case for hyper-converged technology. However, an extremely high-capacity environment may be better suited to using object storage or the cloud.

    Today, there are more than a handful of vendors in the hyper-converged market offering systems with varying capacities, compatibility requirements and features. That means storage administrators need to consider many of the same things as they would were they evaluating a traditional SAN or NAS: Is solid-state storage needed for better performance? If so, how much? Is the maximum capacity per hyper-converged node enough for your environment? Does implementing a reference architecture make sense, or should software-only products that are implemented on commodity hardware be considered?

    This buyer's checklist helps storage administrators make an educated purchase decision by providing an overview of the options on the hyper-converged market today, how they differ, which features customers should look for and the top use cases for hyper-converged storage systems.

  • Learn how to assess all-flash array vendors

    Arrays loaded with flash drives are the speed kings of storage arrays. They can also be more expensive than traditional systems with hard disk drives (HDDs), so IT managers need to assess their application needs to make the best decision among all-flash array vendors.

    Cheap HDDs give traditional arrays an advantage in price per GB, but systems equipped only with more costly flash drives can provide a significant edge in price per IOPS. Hybrid arrays combining HDDs and solid-state drives (SSDs) are yet another option to consider when balancing the price-performance equation.

    Points of comparison for IT organizations weighing the various options from all-flash array (AFA) vendors include IOPS, latency, throughput, raw and usable capacity, flash type, networking options, architecture type (scale-up vs. scale-out), and supported storage features, such as data deduplication and compression, thin provisioning, snapshots, replication and encryption.

    The original use case for AFAs was typically to accelerate the performance of a niche application with high I/O requirements. AFAs have since become more popular for primary storage, running multiple application workloads on a single flash array now that the products offer the capacity, management and storage capabilities to put them on par with HDD-based systems.

    The use of denser, less expensive flash, such as multi-level cell and triple-level cell 3D NAND, and data reduction technologies are giving rise to claims from AFA vendors that their products can match or beat the price of high-end storage arrays equipped with the fastest spinning disks. So IT organizations need to compare the features and capabilities of many of the leading AFAs against specific criteria to select the right AFA to meet their technical and business needs.
