From the SUN catalog -- is this new? solutions.sun.com Scalability---SANsprawl or Planned Growth Most of today''s switched SAN fabrics are embedded into storage systems and are transparent to the IS manager, who manages the switch through the storage vendor''''s interface. But what happens when the IS manager wants to link two or more such systems together or introduce a different vendor''''s storage system into the storage area network? The Solution for Building Large SANs: Ancor''''s Multistage? Ancor Communications has leveraged its experience in growing the world''''s largest Fibre Channel network to develop Ancor''''s Multistage, the multiswitch architecture capable of growing nearly infinitely large SANs without the performance degradation that occurs in other architectures, such as cascaded. Although Ancor also offers cascaded architecture for small, less expensive SANs, only Ancor Multistage architecture offers the greatest number of connections to grow the largest fabrics. And because Ancor''''s switches have the lowest latency in the industry, the largest SANs in the world are also the fastest. Ancor''''s Multistage architecture provides the foundation for growing almost limitless, high?performing SANs. Any of Ancor''''s switch configurations can be an edge or core switch. The Key to Scalability: Highly Integrated Hardware Ancor can deliver the highest-performing, scalable SANs because the SANbox switches are highly integrated?fewer parts result in higher performance, higher reliability, and lower cost. The key to a switch''''s performance is in the application-specific integrated circuit (ASIC). Ancor''''s advanced 4-port ASIC includes embedded memory, enabling on-chip data transfer without going to shared memory. Unlike a shared memory architecture, which eventually becomes limited when too many processors attempt to access the memory, ASICs with embedded memory can grow very large switches and very large SANs?and are the only solution for building SANs that can manage data volumes with infinite growth. Scaling to Include the Legacy Early Fibre Channel installations often included private loop protocol. Private loops are generally built using hubs that communicate by passing messages around the loop from one device to the next. They were labeled "private" because they communicated only with other devices on the same loop and could not be brought into communication with larger public networks. Ancor''''s SANbox protects the customer''''s legacy investment in private loop devices by providing a translation mechanism to bring private loop devices forward?to become an integral part of the public switched SAN. With Ancor''''s unique Full Loop Support (FLS?) facility, both private and public loop devices can be attached to one or more fabric switches?and can be viewed and managed as a single SAN fabric. And as an added bonus, Ancor''''s SANsurfer? management GUI displays all the devices on both public and private loops for easy troubleshooting. ........ ........ Partnering for Growth When OEMs choose Ancor as their switch provider they are getting a lot more than top-performing hardware and software: they are also getting the top-performing people who are Ancor Communications. Our ASIC engineers are years ahead of the competition in Fibre Channel experience, and our account teams are dedicated to each OEM''''s success. We at Ancor understand the importance of quality, cost, timeliness, and open communication?the fundamentals that make business relationships work.
