Five Tough Questions for Your Storage Vendor Just about every storage professional is in a vise these days. They need to manage more and more data and make it available more and more quickly for less and less money. In response, everyone from the smallest angel-funded startup to the industry giants claim they can help. They’re all talking scaling to hundreds of thousands of IOPS and thousand of nodes with their own twist on caching data in server-side flash memory to boost performance. And, of course, no press release is cool unless it makes a reference to software-defined storage, whatever that is. It is true that we’re on the brink of massive, structural changes as intelligent software running on low-cost commodity servers and storage replaces proprietary, high-priced offerings. This will bring the kind of incredibly low-cost, highly reliable systems Google and Am... (more)

Software-Defined Storage: Focus on Benefits, Not Buzzwords

“Software-Defined Storage” is the flavor of the month for vendors hawking storage gear. While it can be a useful way of thinking about storage, it’s not something you can buy, but a set of capabilities. We recommend not getting hung up on formal definitions of “software-defined storage.” Instead, evaluate products on whether they can deliver the key benefits it promises. Those include cost savings, scalability, flexibility, and insuring agility by eliminating single points of failure. Birth of a Buzzword VMware popularized “Software-defined Storage” as part of their Software-D... (more)

Sanbolic Melio Provides Storage Live Migration for Hyper-V

Sanbolic announced on Thursday that Melio now includes the ability to dynamically migrate storage volumes between heterogeneous storage arrays without application interruption. The new capability provides customers with the flexibility to match storage resources with changing workload requirements on Windows-based physical or virtual servers, as well as to easily migrate to new storage array hardware. Sanbolic Melio is a flexible, dynamically assignable shared storage platform for physical and virtual Windows-based servers. Melio enables advanced storage management capability us... (more)

The Need for Software-Defined Data Management Platform

Data center architecture has been evolving rapidly as enterprise compute resources have moved from physical machines to virtualized on-premise machines to hybrid environments which incorporate cloud-based resources. VMware pioneered server virtualization in the enterprise and now describes a vision of the software-defined data center in which compute, network, and storage resources are all abstracted from the physical hardware they run on. Although VMware’s acquisition of Nicira is a step toward this goal, network and storage resources still tend to be tethered to proprietary har... (more)

Why is The Problem with Storage in Virtual and Cloud Computing so hard?

Continuing the post from last week, today we would cover – Why is it so hard? Many vendors have been introducing tools for automating the provisioning of storage silos, for monitoring utilization and performance of storage silos, for making snap ... (more)
