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” 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
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.

for physical and virtual Windows-based servers. Melio enables advanced

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)
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
