Features And Specifications - IBM RackSwitch G8000 Manual

Summary: IBM System Networking RackSwitch G 8000
The IBM System Networking RackSwitch G8000 offers the following benefits:
High performance: The G8000 provides up to 176 Gbps throughput and supports up to four 10 G

uplink ports for a very low oversubscription ratio.
Lower power and better cooling: The G8000 uses approximately 120 W, which is a fraction of the

power consumption of most competitive offerings. Unlike side-cooled switches, which can cause heat
recirculation and reliability concerns, the G8000 rear-to-front/front-to-rear cooling design reduces data
center air conditioning costs by matching airflow to the server's configuration in the rack. Variable
speed fans assist in automatically reducing power consumption.
VM-Aware network virtualization: VMready software on the switch reduces configuration complexity

while significantly improving security levels in virtualized environments. VMready automatically
detects virtual machine movement from one physical server to another, and instantly reconfigures
each VM's network policies across VLANs to keep the network up and running without interrupting
traffic or impacting performance. VMready works with all leading hypervisors, such as VMware, Citrix
Xen, RedHat KVM, Microsoft Hyper V, and IBM PowerVM
Layer 3 functionality: The switch includes Layer 3 functionality, which provides security and

performance benefits, plus static and dynamic routing protocols including Open Shortest Path First
(OSPF) and Border Gateway Protocol (BGP) for enterprise customers.

Fault tolerance: These 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, HotLink™, Uplink Failure Detection (UFD)™,
IGMP V3 snooping, and OSPF.
Seamless interoperability: Switches interoperate seamlessly with other vendors' upstream switches.

Stacking: Cluster virtualization, single IP, and stacking of up to six virtual switches allow configuration

of multiple switches as one, saving valuable time, IP addresses, and resources.
