10 Gb Ethernet Pass-Thru Module for BladeCenter
For many clients looking to use a pass-through module, upstream costs can be expensive,
especially if you are connecting to a core switch and are looking at up to fourteen 10 Gb ports
per chassis. The G8264 provides a much more cost-effective alternative and can support up to
four fully populated BladeCenter H chassis per RackSwitch. This alternative is also much better
for larger BladeCenter H environments compared to a smaller 24-port switch.
Low-profile, high-performance, 48/64-port 10 GbE switch needed for aggregation function per rack.
Figure 4 shows 10 GbE port aggregation, and Table 6 lists the features and benefits.

Table 6. Features and benefits
Features
Line-rate, non-blocking, all 64-ports
Deterministically low latency
Support for IGMP Snooping and L3 forwarding
Standards-based Layer 2/3 protocols; industry standard CLI
Rack-optimized server aggregation: 1 GbE attached rack servers
The design goal is to have the RackSwitch G8264 (10 GbE) switch at the distribution layer and RackSwitch
G8000/G8052 (1 GbE) at the Edge/Access layer.
The G8264 is also ideal at the distribution layer when you are looking to aggregate connections for access layer
