SDS - A Crucial Tool For Improving Data Availability

Storage hardware, on a small island, surrounded by sharks

Posted on Monday, June 12, 2017

When discussing software defined storage (SDS), much of the discussion centers around managing future data growth. Abstracting storage from the underlying hardware allows for simplified resource allocation, and the option to extend capacity using commodity arrays, or existing assets.

But just as virtualized servers changed data center management, SDS provides similar benefits for disaster recovery.

Drop in replacements

In the event of a hardware failure, an SDS environment can shift load and data automatically to another available node. Because the storage infrastructure sits above the physical hardware, any hardware can be used to replace a failed node.

The increase of the white box, no name storage hardware market share is indicative of how many businesses are using SDS to reduce their infrastructure costs. Not only does this make initial deployment cheaper, but the cost of replacing failed nodes is also much lower – arrays can be purchased off the shelf.

Maximizing asset value

Ideally failed nodes will be replaced with brand new kit – but it doesn’t have to. Existing assets can be redeployed in exactly the same way.

Pushing older hardware back into service actually makes perfect sense. Unused, post-warranty assets provide a stable, reliable stop-gap until a new node can be acquired for instance. And there’s nothing at all stopping businesses from making these redeployments permanent – true SDS infrastructure is focused on capacity, rather than the underlying hardware technologies.
