More on Clustered NAS

Clustered NAS is gaining in popularity, and makes the administration of multiple NAS systems streamlined and easier. The difference between NAS and clustered NAS is that a clustered NAS appears to the administrator as one mount point. Previously with traditional NAS, one would have to administer an additional data mover for each NAS added – creating more workload. Imagine having at least 10 data movers. Clustered NAS is often used in very large environments where user demand is high, such as in the “entertainment music industry… uses clustered NAS quite a bit because it allows you to share workflows” (Staimer, 2009). Clustered NAS is primarily targeted at unstructured storage such as documents, music files, and presentation material in contrast to structured data such as databases and application data. According to Staimer, clustered NAS could grow substantially within cloud computing. Clustered file systems enable modular (pay as you grow) storage growth… and scaling in storage capacity (Schultz, 2008). As for cloud computing, clustered NAS and cloud computing “seem tailor made for each other because cloud=based services have the need for massive scaling and moderate performance while being very cost effective: (Crump, 2008). Cloud computing, a distributed nature, fits clustered NAS very well due to the replication nature within each technology. Traditional NAS is usually not replicated automatically (it is an add-on), but clustered NAS is – the answer to cloud computing storage demands for dynamic storage growth.
