  • What's to gain by adopting all-flash arrays?

    All-flash arrays increase the number of VMs allowed per physical host. This affects the configuration, performance and even spending decisions in a virtualized data center. Powerful all-flash arrays compress data at impressive levels. As a result, admins who put flash into action in a data center can improve storage performance and at the same time increase the number of VMs per physical host.

    This has effects on server selection, VM configuration and overall performance of an IT infrastructure. While there'll be reasonable concerns about the purchase costs, there are factors that can make calculating the ROI for an all-flash array less daunting. This three-part guide explores these issues and considers why an organization might consider adopting all-flash arrays.

  • Becoming familiar with VM-aware storage

    As with any product still in its infancy, an exact definition for virtual machine-aware storage can be difficult to nail down. In simple terms, VM-aware storage is an appliance that vendors build specifically with virtual machines in mind in order to cut back on some of the most pertinent issues in virtual environments: complexity, difficult management and lagging performance.

    Using VM-aware storage typically means there's no need to configure logical unit numbers and volumes, and because VMs are directly associated with the storage they reside on, priority can be given to more demanding apps and VMs can be granularly managed. This guide will walk you through what products classify as VM-aware storage, how they are implemented in virtual environments and what benefits they can bring to storage and virtualization administrators so you can make an informed decision about whether they're the right choice.

  • In cloud storage, options abound

    This handbook examines cloud-based storage in terms of cost, manageability, scalability, security, latency/availability and more. While cost and security remain pressing concerns, cloud-based storage holds an increasing appeal for more organizations–and not simply for data backup. Determining its fit for a particular organization, though, involves a careful look at the use case, security requirements, costs, ease of data transfer, and regulatory compliance among other factors. A business is likely to want to tailor its use of cloud storage to specific uses. For example, transaction data is probably best stored on high-IOPS devices when used with interactive applications but stored on low-cost disk when used for analysis. And an organization will want to be alert for unexpected costs, such as when snapshot backups accumulate.Continue Reading
