VM-aware networking

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 affecting performance. VMready works with all leading VM

providers, such as VMware, Citrix Xen, and Microsoft Hyper-V.

Layer 3 functionality

The G8264 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

RackSwitch switches perform seamlessly with other vendors' upstream switches.

Fault tolerance

RackSwitch switches learn alternative routes automatically and perform faster convergence if there

is a link, switch, or power failure. The switch uses proven technologies, such as L2 trunk failover,

advanced VLAN-based failover, VRRP, and Hot Links.

Multicast

The G8264 supports IGMP Snooping v1, v2, and v3 with 2 K IGMP groups. It also supports

Protocol Independent Multicast (PIM), such as PIM Sparse Mode or PIM Dense Mode.

Converged fabric

The G8264 switch supports CEE and connectivity to FCoE gateways. CEE helps enable clients to

combine storage, messaging traffic, VoIP, video, and other data on a common data center Ethernet

infrastructure. FCoE helps enable highly efficient block storage over Ethernet for consolidating

server network connectivity. As a result, clients can deploy a single server interface for multiple data

types, which can simplify deployment and management of server network connectivity while

maintaining the high availability and robustness that is required for storage transactions.

OpenFlow enabled

The RackSwitch G8264 is the first 10 GbE switch to offer benefits of OpenFlow. OpenFlow is the

new open 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 G8264 is also the ideal switch to use with industry compliant OpenFlow controllers.

Transparent networking capability

With a simple configuration change to Easy Connect Mode, the RackSwitch G8264 becomes a

transparent network device that is invisible to the core and eliminates network administration

concerns of Spanning Tree Protocol configuration and interoperability and VLAN assignments and

avoids any possible loops.

By emulating a host NIC to the data center core, it accelerates the provisioning of VMs by

eliminating the need to configure the typical access switch parameters.
