EMC has introduced its content addressed storage (CAS) architecture, based on a new storage server called Centera at a launch event headed by president and EMC chief executive officer Joe Tucci.

The Centera systems use a method called content addressing to tag what are commonly referred to as reference files - medical X-rays, check images, video media - with the equivalent of a digital fingerprint, making it easier for the Centera storage server to retrieve them.

CAS and EMC's Centera server step outside the existing SANs and NAS storage networking architectures, and specifically cater to the efficient delivery of reference files, Tucci said.

"The idea is that CAS is a complementary storage platform to SANs and NAS, optimised specifically around managing large amounts of fixed content," said Barry Burke, director of integrated solutions for networked storage platforms at EMC.

Thirty-two rackable Centera storage server nodes fit within a six-foot rack, and the system scales in clusters to more than 1120TBytes, according to EMC.

CAS technology and the Centera server platform position EMC to take advantage of what experts predict will be a booming market for unchanging "reference" data.

An entry-level Centera system with 16 server nodes and 10TBytes of storage starts at $210,000 (£144,113), software included.
