Tangible Performance benefits of Intelligent Scale-out SDN-powered Storage

The major limitation of the scale-up storage arrays has been the storage controller, which often becomes the performance bottleneck. This limitation gave birth to the scale-out phenomenon that has dedicated controller for each node. This approach eliminates any performance bottleneck caused by the limited horsepower of the controller. CIOs fancy the notion of utilizing industry standard commodity hardware in modular building blocks that allows them to easy to scale from TBs to PBs using interconnects while presenting a single logical storage target requiring zero reconfiguration to add capacity – all under a single namespace.

Software Defined Storage (SDS) and Software Defined Networking (SDN) have emerged as some of the best and brightest platforms for distributed storage systems designed for excellent performance, reliability, and exabyte-level scalability running on commodity hardware. They enable organizations to be flexible, agile, and efficient with their infrastructure and easily and cost effectively extend it as their needs grow. These tangible benefits has fortified the place for these software-defined technologies as the center of the distributed infrastructure hub.

SDS & SDN abstract the controller functions from the storage and networking hardware  and moves them into software. These functions can include volume management, RAID, resource pooling, data protection, compression, data deduplication, high availability (HA), snapshots and replication, to name a few. The controller functions can be placed just about anywhere within the storage infrastructure. The controller can run on dedicated hardware, within a hypervisor, or alongside virtual machines. Therefore, storage becomes a shared pool of resources that runs on x86-based commodity hardware.

Key advantages of separating and abstracting the controller functions are:

  1. Simplification of storage provisioning and management
  2. Leveraging commodity storage hardware – the storage system could be built out of commodity hardware, with high performance.
  3. Increased performance and reliability – braking the storage controller physical layer into a virtual switch eliminates the performance bottlenecks resulting in higher performance.
  4. Programmability and centralized management.

On the storage technology front, SSDs have been the first major improvement in storage performance in the last 30 years. SSDs have helped redefine consumer and enterprise storage by replacing slower, more error-prone HDDs, while providing balance of speed and cost opens new levels of performance to throughput-starved, disk-based applications.

In this webinar an expert panel will examine the pros and cons of SDN powered scale-out storage architecture.
