22 Implementing IBM System Networking 10Gb Ethernet Switches

򐂰 Seamless interoperability: IBM System Networking RackSwitches interoperate seamlessly

with other vendors' upstream switches.

򐂰 Fault tolerance: IBM System Networking RackSwitches learn alternative routes

automatically and perform faster convergence in the unlikely case of a link, switch, or

power failure. The switch uses proven technologies, such as L2 trunk failover, advanced

VLAN-based failover, VRRP, and Hot Link.

򐂰 Multicast: Supports IGMP Snooping v1, v2, and v3 with 2 K IGMP groups, and Protocol

Independent Multicast, such as PIM Sparse Mode or PIM Dense Mode.

򐂰 Converged fabric: The IBM System Networking RackSwitch is designed to support CEE

and connectivity to FCoE gateways. CEE helps enable clients to combine storage,

messaging traffic, VoIP, video, and other data on a common data center Ethernet

infrastructure. FCoE helps enable highly efficient block storage over Ethernet for

consolidating server network connectivity. As a result, clients can deploy a single server

interface for multiple data types, which can simplify both deployment and management of

server network connectivity, while maintaining the high availability and robustness

required for storage transactions.
