For Ethernet Switch Modules with SFP+ or X2 ports see the particular IBM Redbooks at-a-glance guide to fix up transceivers supported. Review Table 5 for superintendence on how to link up the Ethernet Switch Module to the B24X.
Popular configurations
This division illustrates how the IBM Ethernet Switch B24X may be used in assorted configurations.
Top of Rack switch
An access or corner switch is a switch that connects right away to the finish gadgets requiring network connectivity, many ordinarily servers and storage arrays in the information center. A switch that is 1 or 2 RU in tallness that acts as the access switch for gadgets inside of a shelve is ordinarily called a Top of Rack switch.
The B24X is preferred for deployment as an all-purpose Top of Rack switch in rigorous network environments due to its high-performance, volatile hardware characteristics and thorough network features support. The B24X can moreover be used to encouragement NAS or iSCSI SAN storage in a common or dedicated network mood (Figure 6).

Table 8 outlines the components used in Figure 6.
Table 8. Components used in anxiety to Figure 6
Forty-one shelve units (with two RU servers)
1:1 subscription proportion inside of rack
2.43:1 over-subscription proportion to rest of network
Connectivity to NAS or iSCSI SAN (or both) for mid-range scalable storage
In the answer shown in Figure 6 you have two IBM Ethernet Switch B24Xs providing connectivity to all gadgets inside of a singular rack. Within the shelve you have a blend of servers with 10 GbE connectors to any B24X for redundancy. The B24X can moreover be used to link up to NAS arrays for scale-out file pity and moreover to a well-defined iSCSI SAN for dedicated storage access as bandwidth and safety needs require.
