Non-traditional alternatives

There are three non-traditional approaches to NAS consolidation: clustered

file systems, parallel file systems and NAS aggregators. Many vendors tout

their NAS gateways as a means of providing independent performance

scaling for both the back- and front-end. Some non-traditional alternatives

take this a step further by allowing not just a scale-up of performance in

the front end (by increasing node horsepower), but a scale-out of the front

end by adding multiple independent nodes that can access the same

single namespace.

Clustered and parallel file systems: Clustered file systems operate

across multiple nodes (generally more than eight) and use off-the-shelf

hardware and/ or standard operating system software. The nodes can be

specialized, such as meta data nodes and storage nodes, or generic,

supporting both meta data and storage services. Some products

mentioned in the previous sections support from two to eight NAS box

clusters for high availability. However, none of the products previously

mentioned does this to quite the extent available from clustered or parallel

file-system products. A true clustered or parallel file system scales

performance linearly as the number of nodes increases and provides

access to the same data across all nodes.

Clustered file systems are good for companies with large compute clusters

that need high-performance access to file-system data. One key

advantage of these products is that performance can be dialed up almost

as high as you want by adding nodes to the cluster. However, these

products may not be as useful for Windows users, as some have limited

(or no) support for CIFS, but this is vendor-specific.
