SME Stack V0.1, Part 3 – Storage Solutions

January 2, 2009

If storage is the key, shared storage the key that opens all locks. In the early days of file servers, shared storage meant a common file store presented to users over the network infrastructure. This storage was commonly found in a DAS array – usually RAID1 or RAID5 – and managed by a general purpose server operating system (like Windows or Netware). Eventually, such storage paradigms adopted clustering technologies for high-availability, but the underlying principles remained much the same: an extrapolation of a general purpose implementation.

Today, shared storage means something completely different. In fact, the need for “file servers” of old has not disappeared but the dependency on DAS for the place where stored data is ultimately placed has moved to the network. Network attached storage – in the form of filers and network block devices – are replacing DAS as companies retire legacy systems and expand their data storage and business continuity horizons. Today, commercial and open source software options abound that provide stability, performance, scalability, redundancy and feature sets that can provide increased functionality and accelerated ROI to their adopters.
