With the flexibility of the IBM G8264T, you can take advantage of the following technologies that are required for multiple environments:
- For 1 Gb links, you can simple use Cat5 type cabling.
- For 10 Gb, you can use the following items:
- 10GBase-T allows CAT6 or CAT6A cables for cost-effective long distances.
- Leverage the QSFP+ break out cable to get up to four 10Gb SFP+ connections per QSFP+ port.
- For 40 G to 40 G connectivity, clients can use IBM QSFP+ to QSFP+ cables up to 7 meters, or combine 40 G transceivers and optical cables for longer distances. For distances of up to 100 meters, clients can use QSFP+ SR4 transceivers which use optical cables with MTP connectors using OM4 grade fiber. For distances up to 10 km, clients can use the QSFP+ LR4 transceiver, which uses optical cables with LC connectors using single mode fiber (SMF).

The IBM System Networking RackSwitch G8264T offers the following benefits:
- Low cost cabling
The ability to use CAT6 or CAT6A cabling can save clients thousands of dollars for connections anywhere from a couple of feet to 100 meters, compared to SFP+ models.
- High performance
If you require the use of 10GBase-T, the 10-Gb/40-Gb capabilities provide the best combination of nonblocking line-rate switching with throughput of 1.2 Tbps.
- Lower power and better cooling
The typical power consumption of the IBM RackSwitch G8264T is 385 W, which is a fraction of the power consumption of most competitive 10GBase-T offerings. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the front-to-rear or rear-to-front cooling design of the G8264T reduces data center air conditioning costs by having airflow match the servers in the rack. In addition, variable speed fans assist in automatically reducing power consumption.
- VM-aware networking
IBM VMready software on the switch simplifies configuration and improves security in virtualized environments. VMready automatically detects virtual machine movement between physical servers and instantly reconfigures the network policies of each VM across the VLANs to keep the network up and running without interrupting traffic or impacting performance. VMready works with all leading VM hypervisors.
- Layer 3 functionality
The IBM switch includes Layer 3 functionality, which provides security and performance benefits, as inter-VLAN traffic stays within the switch. This switch also provides the full range of Layer 3 protocols from static routes for technologies such as Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers.
- Seamless interoperability
IBM switches perform seamlessly with upstream switches from other vendors.
- Fault tolerance
These IBM switches learn alternate 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 HotLink.
- OpenFlow enabled
The RackSwitch G8264T offers benefits of OpenFlow. OpenFlow is the new open application programming interface (API) that enables the network administrator to easily configure and manage virtual networks that control traffic on a “per-flow” basis. It creates multiple independent virtual networks and related policies without dealing with the complexities of the underlying physical network and protocols. The G8264T can also be used with the IBM Programmable Network Controller, which is the IBM network controller that is compliant with OpenFlow.
Supports IGMP Snooping v1, v2, and v3 with 2 K IGMP groups, in addition to Protocol Independent Multicast (PIM) such as PIM Sparse Mode or PIM Dense Mode. See Table 4 to select the appropriate switch.

This section describes the following common configurations for the G8264T:
- Rack-optimized server aggregation for rack servers using 10GBase-T
- iSCSI storage implementation
Rack-optimized server aggregation for rack servers using 10GBase-T
The RackSwitch G8264T is an ideal networking device for port aggregation, allowing the consolidation of one to three racks full of IBM System x type servers before connecting to an upstream switch. IBM System x servers can use a 10GBase-T adapter installed, such as the Broadcom NetXtreme II Dual Port 10GBase-T Adapter for IBM System x, and then CAT6/6A cables can be used to connect upstream to the G8264T. The RackSwitch G8316 would be an attractive offering for 40Gb upstream connects from the G8264T helping clients create a flat two layer networking implementation as shown in Figure 4.
