Transceivers are not included in the purchase of the switch, and all transceivers require the appropriate cables (see Table 2). Power cords are also not included and must be ordered separately (see Table 3).


Features and benefits

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. Clients must invest in separate infrastructures for LAN, SAN, and interprocess communications (IPC) fabrics, including host adapters, cables, switching, routers, and other device-specific equipment.

The IBM 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 thirty-six 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.

  • Optimizes network virtualization with innovative software

    With most IT organizations implementing virtualization, a need has increased to reduce the cost and complexity of their environments. IBM Virtual Fabric reduces cost and complexity while increasing performance. It also provides higher availability and security with isolation between virtual network interface cards (vNIC) by using the innovative IBM Networking OS design. In addition, delivering advanced virtualization awareness helps simplify management and automates virtual machine (VM) mobility by making the network VM aware with IBM VMready®, which works with all the major hypervisors.

  • 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 for IBM, 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, Citrix, Xen, IBM PowerVM®, and Microsoft.

  • 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

    IBM switches perform seamlessly with other vendors' upstream switches.

  • Fault tolerance

    These IBM 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 HotLink.

  • Multicast support

    These switches support IGMP Snooping v1, v2, and v3 with 2 K 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 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.

Leveraging an existing LAN

Figure 5 shows how a client with existing SAN switches can use the G8264CS to simplify its rack environments by introducing Ethernet in the rack between the IBM System x, or IBM Power Systems servers, and the G8264CS. The client can introduce Ethernet 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.

Leveraging Ethernet further in an existing data center

Figure 6 shows an example of how a client might further simplify its data center by using Ethernet more in its data center before connecting to its existing SAN switches. This example shows how clients can use the IBM RackSwitch G8124E to simplify its rack environments with Ethernet only. Ethernet can go down to the end of the row, or closer, to the client's storage where the client can install the G8264CS. 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 FCoE end to end in an existing data center

Figure 7 shows an example of how a client might further simplify their data center by further simplifying things and doing away with the FC SAN switching fabric and implementing and to end FCoE configuration. This example shows how clients can use the IBM RackSwitch G8264 to simplify their rack environments with Ethernet only. Ethernet can go down to the end of the row, or closer, to the client's storage where the client can install the G8264CS to connect directly upstream to an IBM Storwize V3700/V7000 using simpler Ethernet connectivity.

Leveraging an IBM BladeCenter environment

Figure 8 shows an example of how a client can use an IBM BladeCenter environment. The client reduces costs inside the chassis with a single adapter in the blade, with a 10-Gb Ethernet adapter only in the chassis. The client can use the G8264CS at the top of the rack or somewhere else in the data center, breaking out the FC connections and connecting to the existing SAN switches, and then to the storage devices.

Leveraging an IBM Flex or PureSystems environment: NPIV to FC SAN

Figure 9 shows an example of how a client can use the G8264CS for convergence in a Flex or PureSystem environment. This approach can help a client significantly reduces costs inside the chassis with a single adapter in the compute node using CNA functionality, with a 10Gb Ethernet module, such as the SI4093/EN4093/EN4093R, in the chassis (no FC adapter or switches necessary). The client can then use the G8264CS at the top of the rack or somewhere else in the data center, breaking out the FC connections and connecting to the existing Brocade or Cisco SAN switches, and then in to the storage devices.

Leveraging an IBM Flex or PureSystems environment: FCoE end-to-end

Figure 10 shows an example of how a client can use the G8264CS for convergence in a Flex or PureSystem 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. In the chassis, you simply have a single adapter in the compute node using CNA functionality, with a 10Gb Ethernet module, such as the SI4093/EN4093/EN4093R, in the chassis (no FC adapter or switches necessary). The client can then use the G8264CS at the top of the rack or elsewhere in the data center and then connect directly into the storage device.

Note: FLOGI is used to obtain a routable FCID for use in the FC frame exchange between the G8264CS and the Storwize V7000. The switch provides the FCID during a FLOGI exchange.
