Technology and Architecture
Isilon clustered storage system architecture consists of independent nodes that are all integrated with the OneFS operating system software. The systems can be installed in standard data center environments and are accessible to users and applications running Windows, Unix/Linux and Mac operating systems using industry standard file sharing protocols over standard Gigabit Ethernet.
Nodes within the clustered storage system communicate with each other over a dedicated back-end network which is either Infiniband or standard Gigabit Ethernet. The architecture is designed so that each node has full visibility and write/read access to or from a single expandable file system.
The core technology of the Isilon clustered storage consists of OneFS, which provides a single unified operating system and delivers up to 10 GB/s of throughput. The OneFS operating system software is designed with file-striping functionality across each node in a cluster, a fully distributed lock manager, caching, fully distributed meta-data, and a remote block manager to maintain global coherency and synchronization across the cluster.
In July 2007, Isilon announced the release of the IQ 9000 and EX 9000 clustered storage products, claiming scalability of up to 1.6 petabytes of capacity in a single file system and single volume. New products were launched in September 2008, raising stated capacity to 2.3 PB and in March 2009, raising stated capacity to 3.4 PB. In May 2011, they raised the stated capacity to 15 PB.

Famous quotes containing the words technology and/or architecture:
“Radio put technology into storytelling and made it sick. TV killed it. Then you were locked into somebody else’s sighting of that story. You no longer had the benefit of making that picture for yourself, using your imagination. Storytelling brings back that humanness that we have lost with TV. You talk to children and they don’t hear you. They are television addicts. Mamas bring them home from the hospital and drag them up in front of the set and the great stare-out begins.”
—Jackie Torrence (b. 1944)
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
