The RackSwitch G8264CS offers the following features and benefits:

Lowers the total cost of ownership (TCO) with consolidation

By consolidating LAN and SAN networks and converging to a single fabric, clients can reduce the equipment

that is needed in their data centers. This benefit significantly reduces the costs that are associated with energy

and cooling, management and maintenance, and capital costs.

Improves performance and increases availability

The G8264CS is an enterprise-class and full-featured data center switch that offers high-bandwidth

performance with 36 1/10 Gb SFP+ connections, 12 Omni Ports that can be used for 10 Gb SFP+

connections, 4/8 Gb Fibre Channel connections, or both, plus four 40 Gb QSFP+ connections. The G8264CS

switch delivers full line rate performance on Ethernet ports, making it an ideal choice for managing dynamic

workloads across the network. This switch also provides a rich Layer 2 and Layer 3 feature set that is ideal for

many of today's data centers. Combined with redundant hot-swappable power and fans, along with

numerous high availability features, this switch comes fully equipped to handle the demands of business-

sensitive traffic.

High performance

The 10 Gb/40 Gb switch provides the best combination of low latency, non-blocking line-rate switching, and

ease of management. It has a throughput of up to 1.28 Tbps.

Lower power and better cooling

The G8264CS uses as little as 330 W of power, 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 front-to-rear or rear-to-front cooling design of the G8264CS switch reduces the costs of data

center air conditioning by having airflow match the servers in the rack. In addition, variable speed fans help to

automatically reduce power consumption.

Support for Virtual Fabric

The G8264CS can help customers address I/O requirements for multiple NICs while reducing cost and

complexity. By using Virtual Fabric, you can carve a physical dual-port NIC into multiple vNICs (between 2 - 8

vNICs) and to create a virtual pipe between the adapter and the switch for improved performance, availability,

and security. It is also important to know support for FCoE, as 2 vNIC cans be configured as CNAs to allow for

additional cost savings through convergence.

VM-aware networking

VMready software on the switch simplifies configuration and improves security in virtualized environments.

VMready automatically detects virtual machine movement between physical servers and instantly reconfigures

the network policies of each VM across VLANs to keep the network up and running without interrupting traffic

or impacting performance. VMready works with all leading VM providers, such as VMware vSphere, Citrix Xen,

IBM PowerVM, and Microsoft Hyper-V.

Layer 3 functionality

The G8264CS includes Layer 3 functionality, which provides security and performance benefits, because

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

The G8264CS switches perform seamlessly with other vendors' upstream switches.

Fault tolerance

The G8264CS switches learn alternative 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, and Hot Links.

Multicast support

These switches support IGMP Snooping v1, v2, and v3 with 2K IGMP groups. They also support Protocol

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

Transparent networking capability

With a simple configuration change to easy connect mode, the RackSwitch G8264CS becomes a transparent

network device, invisible to the core, eliminating network administration concerns of Spanning Tree Protocol
