Abstract
Storage Networking For the Virtual Enterprise

 This Session will review the latest in storage networking
protocols for EMC storage platforms. Topics include new
architecture for scaling SAN fabrics, new features for enhancing
SAN metro connectivity, and powerful new capabilities for
enhancing SAN Management. We will also review Ethernet
Fabric architectures for FCOE, iSCSI and NAS.
 At the end of this session you will be able to:
– Understand how to deploy large SAN Fabrics using multiple
directors without sacrificing server and storage ports.
– Learn about the new SAN capabilities that will significantly
improve Metro connectivity over DWDM or dark fiber.
– Understand how Ethernet Fabrics provide performance, scale and
ease of manageability compared to traditional Ethernet
hierarchical topologies.
