Hadoop San Storage

Cloud cloud clustered storage like red hat storage.

Hadoop san storage.

Hadoop is first and foremost a general purpose data storage and processing platform designed to scale out to thousands of compute nodes and petabytes of data. San nas appliance an enterprise storage system or appliance. Storage area networks sans are the most common storage networking architecture used by enterprises for business critical applications that need to deliver high throughput and low latency. Virtualization hadoop running on virtual machines.

The longer answer is that depending on the size of your hadoop implementation and the number of nodes it may not make sense from a cost perspective to use san and network attached storage nas systems as the primary storage layer. Enhanced das hadoop with a proprietary data storage software layer in place of hdfs. The short answer is yes. We look at how hadoop crunches big data its key storage requirements and survey the vendors that offer hadoop storage products.

These two industry factors have led to a partial convergence of nas and san approaches to network storage effectively creating high speed high capacity and centrally located network devices. When considering hadoop s capabilities for working with structured data or working with data of any type for that matter remember hadoop s core characteristics. Also emerging is the unthinkable replacing das with nas or san as hadoop s primary storage layer. Let s take a look at these latter four.

San for hadoop storage. Hadoop changes the game for enterprise storage. For now however stick to your guns and keep your hdfs. All the normal advantages of arrays.

Instead of storing data on direct attached local disks data is in one or more arrays attached to data nodes through a san. Looks like local storage to data nodes hadoop still utilizes hdfs. We re now seeing the use of san and nas as secondary storage for hadoop clusters storage that essentially functions as a data protection and or archival storage layer in conjunction with hadoop s das based primary storage layer.

Look for appliances that shove bits of hadoop down to the hardware layer in a hybrid san server setup to come out in the coming year or two.
