Key features

The traditional approach of segmenting storage and data traffic has certain advantages, such as traffic
isolation and independent administration. Nevertheless, it also poses several disadvantages, including
higher infrastructure costs, complexity of management, and under-utilization of resources. Customers must
invest in separate infrastructures for LAN, SAN, and inter-process communications (IPC) fabrics, including
host adapters, cables, switching, routers, and other device-specific equipment.

The RackSwitch G8264CS is considered particularly suited for the following customers:

Customers who want to implement a converged infrastructure with FCoE where the G8264CS acts
as a Full Fabric FC/FCoE switch for the end-to-end FCoE configurations or as a Fibre Channel
Forwarder (FCF) NPV Gateway that breaks out FC traffic for the native Fibre Channel SAN
connectivity.

Customers who are implementing a virtualized environment.

Customers who require investment protection for 40 GbE network connectivity.

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.

The RackSwitch G8264CS offers the following features and benefits:

Lowers the 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 Gb or 8 Gb Fibre Channel connections (or both) and four 40 Gb QSFP+ connections.
The G8264CS switch delivers full line rate performance on Ethernet ports, which makes 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 and 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 253 W of power, which is a fraction of the power consumption of
most competitive offerings. 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
(2 - 8 vNICs) and create a virtual pipe between the adapter and the switch for improved
performance, availability, and security. With support for FCoE, two vNICs can be configured as
CNAs, which realizes more cost savings through convergence.

Lenovo RackSwitch G8264CS 2

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 affecting performance. VMready works with all leading VM
providers, such as VMware vSphere, Citrix Xen, 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 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 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 that is invisible to the core, eliminates network administration concerns
of Spanning Tree Protocol configuration/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.
