SAN over IP

SAN over IP enables companies to build storage infrastructures over IP-based networks, such as intranets and VPNs (Virtual Private Networks).

Strongest protection & lower costs
SAN over IP solutions from CNT protect more of your data than ever before, enabling you to deploy more of your information easily and efficiently to anywhere and leverage your investment in an existing IP network infrastructure.Extending your storage over IP will:
* Lower bandwidth costs by using the existing IP infrastructure for excess capacity and new low-cost IP services
* Lower operating costs by better leveraging network management personnel and reducing hardware and software capital acquisition costs
* Improve time-to-market, through faster network deployment - especially for new startups & dot-com companies
* Offer an expanded set of data movement techniques by streamlining operations through electronic content distribution

Why the interest in SAN over IP?
The single largest cost factor in metro-area and remote SANs is the cost of communications bandwidth. For several years telecommunications companies have continued to lay increasing amounts of fiber optic cable.

Employing this high-speed transport medium, using IP as the routing mechanism, to move storage data offers companies a low-cost bandwidth option necessary for an effective storage infrastructure.

CNT has developed a non-proprietary, standards-based transport protocol that provides enhanced storage application reliability.

How does it work?
Because the IP Layer 4 was not designed for the large quantities of data handled by storage applications, CNT has developed a storage transport protocol that provides enhanced storage application reliability on an IP backbone, along with data compression, alternate routing, load balancing, and enhanced flow control.

This CNT innovation is a unique value-add, and because it enhances only Layer 4 function, the CNT 'SAN over IP' solution is not proprietary and does not deviate from IP standards.

On the network Layer 3, where IP resides, and where data packet creation and network routing take place, the CNT solution uses completely standard OSI IP support. Because of this, CNT's storage transport layer works with any existing, installed router base without requiring any changes to that base.
