Key features
The RackSwitch G8052 switch is considered particularly suited for the following customers:
Customers who want to use GbE in their infrastructure (servers and networking)
Customers who are implementing a virtualized environment and require multiple GbE ports
Customers who require investment protection for 10 GbE ports
Customers who want to reduce total cost of ownership (TCO) and improve performance while
maintaining high levels of availability and security
Customers who want to avoid or minimize oversubscription, which can result in congestion and
loss of performance
Customers wanting to simplify management by stacking up to eight switches and managing them
as a single entity
Customers who want to implement a converged infrastructure with NAS or iSCSI
The switch offers the following key features and benefits:
High performance
The RackSwitch G8052 provides up to 176 Gbps throughput and supports four SFP+ 10 Gb uplink
ports for a low oversubscription ratio and a low latency of 1.8 microseconds.
Lower power and better cooling
The RackSwitch G8052 typically uses only 130 W of power, a fraction of the power consumption of
most competitive offerings. 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 usage.
VM-aware network virtualization
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
hypervisors, such as VMware, Citrix Xen, Red Hat KVM, and Microsoft Hyper-V.
Layer 3 functionality
The RackSwitch G8052 includes Layer 3 functionality, which provides security and performance
benefits and 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 extra cost.
Stacking support
Supports up to eight switches that use a single switch image and configuration file that shares one
IP address and one management interface for simplified management.
Fault tolerance
These 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, Hot Links, IGMP V3 snooping, and OSPF.
OpenFlow enabled
The RackSwitch G8052 offers benefits of OpenFlow. OpenFlow is the 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 be used with any industry compliant OpenFlow controller.
Seamless interoperability
RackSwitch switches interoperate seamlessly with other vendors' upstream switches.
