Summary: IBM System Networking RackSwitch G8052

The IBM System Networking RackSwitch G8052 provides:
  • High performance: The RackSwitch G8052 provides up to 176 Gbps throughput and supports four SFP+ 10 G uplink ports for a very low oversubscription ratio, in addition to a low latency of 1.8 microseconds.
  • Lower power and better cooling: The RackSwitch G8052 typically consumes just 130 W of power, a fraction of the power consumption of most competitive offerings. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the G8052’s rear-to-front or 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: IBM VMready software on the switch simplifies configuration and improves security in virtualized environments. VMready automatically detects VM movement between physical servers 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, Red Hat KVM, Microsoft Hyper V, and IBM PowerVM® hypervisor
  • Layer 3 Functionality: The RackSwitch G8052 includes Layer 3 functionality, which provides security and performance benefits plus the full range of Layer 3 static and dynamic routing protocols, including Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) for enterprise customers at no additional cost.
  • 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.
  • OpenFlow enabled: The RackSwitch G8052 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 G8052 can also be used with any industry compliant OpenFlow controller.
  • Seamless interoperability: IBM switches interoperate seamlessly with other vendors' upstream switches.

The IBM RackSwitch G8052 comes with an IBM limited three-year hardware warranty, including three years of software upgrades.
