Lenovo RackSwitch G8264CS

Many customers successfully use Ethernet and Fibre Channel connectivity from their servers to their LAN and SAN. These customers want to reduce the cost and complexity of these environments by using the capabilities of Ethernet and Fibre Channel convergence.

The Lenovo RackSwitch™ G8264CS top-of-rack switch offers the benefits of a converged infrastructure. As part of its forward-thinking design, this switch has the flexibility for growth and expansion. This switch is ideal for clients who want to connect to 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 features:

• Lossless Ethernet, Fibre Channel, and FCoE in one switch
• A total of 36 SFP+ ports that support 1 Gb or 10 Gb Ethernet
• Flexibility with 12 Omni Ports that support 10 Gb Ethernet or 4/8 Gb Fibre Channel connections
• Can aggregate FC or FCoE traffic and connect to SANs
• Future-proofed with four 40 Gb QSFP+ ports
• Low cost, low complexity, and simpler deployment and management

The RackSwitch G8264CS is shown in the following figure.

Figure 1. Lenovo RackSwitch G8264CS

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.

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.

• 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.

• For 40 GbE to 40 GbE connectivity, customers can use the affordable QSFP+ to QSFP+ DAC cables for distances up to 7 meters or QSFP+ to QSFP+ active optical cables for distances up to 20 meters. These DAC cables and AOCs have QSFP+ connectors on each end, and they do not need separate transceivers.

  With multimode fiber LC cables, customers can use the 40GBASE QSFP+ bi-directional transceivers for distances up to 100 meters with OM3 or up to 150 meters with OM4 MMF LC cables.

  With multimode fiber MPO cables, customers can use the 40GBASE-SR4/iSR4 QSFP+ transceivers for distances up to 100 meters with OM3 or up to 150 meters with OM4 MMF MPO cables. For distances up to 300 meters, the 40GBASE-eSR4 QSFP+ transceiver can be used with OM3 or up to 400 meters with OM4 MMF MPO cables.

  For distances up to 10 kilometers, the 40GBASE-LR4 QSFP+ transceiver can be used with single mode fiber LC cables.

• For 8 Gb or 4 Gb FC links (supported on Omni Ports only), customers can use 8 Gb FC SFP+ SW optical transceivers for distances up to 150 meters (at 8 Gbps speed) or up to 380 m (at 4 Gbps speed) with 50 µ OM3 multimode fiber. For longer distances, the 8 Gb FC LW optical transceivers can support up to 10 kilometers on single-mode fiber. These transceivers can operate at 8 Gbps or 4 Gbps speeds.
