Features And Specifications - IBM RackSwitch G7028 Product Manual

Summary: IBM System Networking RackSwitch G 7028
The RackSwitch G7028 provides the following features:
Performance: The RackSwitch G7028 provides up to 128 Gbps of throughput and supports four

SFP+ 10 G uplink ports for zero oversubscription, and has a port to port latency of 3.3 microseconds.
Lower power and exceptional cooling : The RackSwitch G7028 typically consumes just 45 W of

power. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the
RackSwitch G7028 switch's rear-to-front cooling design reduces data center air conditioning costs by
matching airflow to the server's configuration in the rack.
Fault tolerance: These switches learn alternative paths automatically and perform faster convergence

if there is a link, switch, or power failure. The switch uses technologies such as L2 trunk failover,
advanced VLAN-based failover, HotLink, and Uplink Failure Detection (UFD).
Seamless interoperability : IBM switches interoperate seamlessly with other vendors' upstream

switches.
The RackSwitch G7028 comes with an IBM limited three-year hardware warranty, including three years of
software upgrades.
