Storage Server or Storage Array?

There is a battle for storage location. According to this article on Channel Register, Oracle, Dell, EMC and VMware want it to be in the server, while NetApp and HDS want it to be in the array.


"The modern storage industry, the one shipping networked external storage arrays, has been built on two foundations. One is EMC's establishment of a market for third-party external, block-addressed storage arrays distinct from the server suppliers of the time: HP, IBM, Digital Equipment, etc.

"The other was the invention and establishment of file-addressed network-attached storage (NAS or filers). NetApp is the single most effective proponent of that, although EMC grew to ship more filers than NetApp. EMC and NetApp represent the twin peaks of the external storage array.

"A storage array comes in two flavours. It is either monolithic, with multiple controllers or engines and some fancy interconnect hardware to link these to the storage shelves – think Symmetrix, latterly VMAX – or modular. Modular arrays have two controllers linked – by simpler Fibre Channel or latterly SAS – to the storage shelves. NetApp's FAS arrays and EMC's CLARiiON are classic embodiments of this idea."
