RackSwitch G8264CS
Product Guide
Many clients successfully use Ethernet and Fibre Channel connectivity from their servers to their LAN and SAN.
These clients are seeking ways to reduce the cost and complexity of these environments by using the capabilities of
Ethernet and Fibre Channel convergence.
The RackSwitch™ G8264CS top-of-rack switch (shown in Figure 1) offers the benefits of a converged infrastructure.
As part of its forward thinking design, this switch has flexibility for future growth and expansion. This switch is ideal
for clients who are looking to connect to existing SANs and clients who want native Fibre Channel connectivity, in
addition to support for such protocols as Ethernet, Fibre Channel over Ethernet (FCoE), and iSCSI.
The RackSwitch G8264CS includes the following highlights:
Lossless Ethernet, Fibre Channel, and FCoE in one switch
36 SFP+ ports supporting 1 Gb or 10 Gb Ethernet
Flexibility with 12 Omni Ports that support 10 Gb Ethernet or 4/8 Gb Fibre Channel connections
Ideal for clients looking to aggregate FC or FCoE traffic with the ability to connect to existing SANs
Future-proofed with four 40 Gb QSFP+ ports
Low cost, low complexity, and simpler deployment and management

Did you know?
The RackSwitch G8264CS simplifies deployment with its innovative and flexible Omni Port technology. The 12 Omni
Ports on the G8264CS give clients the flexibility to choose a 10 Gb Ethernet, 4/8 Gb Fibre Channel, or both for
upstream connections. In FC mode, Omni Ports provide convenient access to FC storage. The Omni Port technology
that is provided on the G8264CS helps consolidate enterprise storage, networking, data, and management onto a
simple-to-manage, efficient, and cost-effective single fabric. Also, the G8264CS can be used to create 252-node
PODs or clusters with Flex System Interconnect Fabric.

    Note: Power cables are not included and must be ordered separately (see Table 2 for details). The G8264CS switch supports up to two redundant hot-swap 550 W AC power supplies for front-to-rear air flow or 750 W AC power supplies for rear-to-front air flow (two power supplies come standard with the switch) and up to four redundant hot-swap fan assemblies (four fan assemblies come standard with the switch).

    G8264CS (front-to-rear airflow) switch also supports 4-post iDataPlex® rack kit (90Y3535) which is used when the switch is installed in the iDataPlex Rack. The G8264CS switch ships standard without any AC power cables. Table 2 lists the part numbers and feature codes to order the power cables (two power cables are required per switch).

    To increase the number of available 10 GbE ports, clients can split out four 10 GbE ports for each 40 GbE port using QSFP+ DAC Breakout Cables for distances up to 5 meters. For distances up to 100 m, optical MTP-to- LC break-out cables can be used with the 40GBASE-SR4 transceiver, but Lenovo does not supply these optical breakout cables.

    The RackSwitch G8264CS is considered particularly suited for these clients: Clients 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 breaking out FC traffic for the native Fibre Channel SAN connectivity.

    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.

    Leveraging an existing LAN Figure 4 shows how a client with existing SAN switches can use the G8264CS to simplify its rack environments by deploying 10 Gb Ethernet in the rack between the System x or ThinkServer® servers, and the G8264CS. The client can leverage Ethernet in the rack while breaking out the FC connections at the top of the rack, to connect to the existing SAN switches, and then on to the client's storage devices.

Next, Ethernet can break out the FC connections at the top of the rack to connect to the existing SAN switches, and finally it can go on to the client's storage devices.

    Leveraging a Flex System environment: FCoE end-to-end Figure 9 shows an example of how a client can use the G8264CS for convergence in a Flex System environment to connect directly into their storage using FCoE. This approach can help clients significantly reduce costs inside the chassis by removing the need for FC SAN switches between the G8264CS and the storage.
