SDS software-defined storage

SDS Software-Defined Storage

Traditional storage architectures rely on complex and proprietary hardware to build a centralized, monolithic storage array. While SAN and NAS-based architectures have been the mainstay of many enterprise datacenters, they are straining under the demands of a modern virtualized environment. They simply were not designed to handle the explosion of VMs and the resulting I/O needs of today’s enterprise. These legacy devices offer limited scalability options.

Software-defined storage, on the other hand, breaks these limitations by moving the infrastructure and control plane away from a rigid hardware platform, into a software–based architecture. This is accomplished by use of an abstraction layer that separates the data from the underlying disk and a distributed file system that permits a scale-out architecture that spans multiple storage nodes.

Software defined storage has three primary characteristics that separate it from traditional storage architectures:

  • Abstraction – software-defined storage solutions use a hypervisor to abstract (or virtualize) storage capacity from the underlying disk hardware. This abstraction eliminates hardware specific limitations and makes possible the use of disparate hardware within a single platform.
  • Pool – the abstracted storage capacity from distributed nodes is aggregated into a large resource pool. This makes the addition of additional capacity or high-performance storage a matter of plug-and-play rather than purchase and migrate.
  • Provision – Once pooled, storage can be quickly and programmatically provisioned based on configurable policies or classes rather than manual configuration.

The Yottabyte Difference

yyStor – Yottabyte’s software-defined-storage platform uses intelligent software and resource virtualization to replace antiquated systems with highly scalable building block appliances.

Rather than using an expensive fibre network and dedicated adapters, yStor allows you to build a distributed platform that connects your configured servers into a scalable virtual SAN that costs up to 70% less than traditional storage arrays.

A Yottabyte-built vSAN can employ virtually any type of disk hardware, as well as combinations of disparate disks depending on your use-case, and does not require highly technical personnel to build and maintain it. With the vSAN, hardware-centric controllers are not necessary and arrays can be distributed across multiple chassis, eliminating ‘maximum device’ limitations. Removing the need for disk-array hardware makes any range of disk devices available for use, from inexpensive, slower-spinning, “green” drives to high-IOP, enterprise-solid state drives for even the most IO-hungry VM’s.

  • Significant Cost Savings – you don't need an expensive, proprietary enclosure, special switches or adaptors. The yStor transforms commodity x86 servers and direct-attached disk into a powerful distributed storage platform.
  • Unmatched Scalability – With no central array, yStor eliminates "maximum device" limitations. You can add performance or storage capacity simply by adding additional scale-out building blocks.
  • Incredible Flexibility –With yStor, if you want to add capacity in one location and remove it in another, yStor will automatically re-allocate the capacity to meet the demand.

yStor eliminates the limitations found in traditional storage devices: it lowers the cost of entry; reduces the cost of ownership; and creates an agile infrastructure that adapts to your changing business environment.
