In the solution shown in Figure 9 we have two IBM Ethernet Switch B48Ys providing connectivity to all
devices within a single rack. The B48Ys can be in a stacked or non-stacked configuration:
In a stacked configuration, two of the four 10 GbE ports are used for stacking to provide a
z
high-bandwidth backplane between the switches. Stacking simplifies manageability and allows
servers to utilize Active-Active NIC teaming with standards-based link aggregation to each of the two
switches in the rack. The remaining four 10 GbE ports in the dual-stacked switches connect to the
rest of the network, providing 40 Gbps of bandwidth to the rest of the network. See Figure 7 for an
example.
In a non-stacked configuration, up to four 10 GbE uplinks per switch can be used to connect to the
z
rest of the network, allowing organizations to deploy highly utilized networks while avoiding
congestion during peak usage.
The B48Y can also be used to connect to NAS arrays for scale-out file sharing and also to a separate
iSCSI SAN for dedicated storage access as bandwidth and security needs require.
