IBM BNT RackSwitch G8124
IBM System x at-a-glance guide
The IBM BNT RackSwitch G8124 delivers exceptional performance that is both lossless and low latency. In addition, the G8124 delivers excellent cost savings as you consider acquisition costs, energy costs, plus its feature-rich design with when it comes to virtualization, CEE/FCoE, high availability, and its enterprise class Layer 2 and Layer 3 functionality.

Did you know
Did you know that:
z
The G8124 switch is designed to support a number of separate types of configurations from a server or downstream switches: 1 Gb, 10 Gb, virtual NIC, Converged Enhanced Ethernet (CEE/FCoE), and iSCSI. This single switch can handle all these workloads and can connect to an upstream 1 Gb or 10 Gb infrastructure, or both.
z
The G8124 is designed to support data center bridging (DCB), which is the IEEE’s group of protocols that provide Lossless Ethernet and allows for clients to reduce the costs of implementing FCoE by leveraging port aggregation before connecting to more costly upstream gateway devices.
z
IBM Virtual Fabric helps clients reduce costs and complexity in environments where they need four or more NICs per server. A perfect example is virtualization, where clients often need as many as eight NICs per server.
z
IBM is a leader in helping clients reduce the complexity of managing VM’s and VM migration with their VMready product, which makes the network VM aware.

With the flexibility of the G8124 switch, clients can take advantage of the technologies that they require for multiple environments. For 10 Gb uplinks, they have a choice of either SFP+ transceivers (SR or LR) for longer distances or more cost-effective and lower-power-consuming options such as SFP+ direct-attached cables (DAC or Twinax cables), which can be 1 - 8.5 meters in length and are ideal for connecting chassis together, connecting to a Top of Rack switch, or even connecting to an adjacent rack.

IBM BNT RackSwitch G8124 3
Benefits
The IBM BNT RackSwitch G8124 offers the following benefits:
z
High performance: The 10G Low Latency (<700 nanoseconds) switch provides the best combination of extremely low latency, non-blocking line-rate switching and ease of management.
z
Lower power and better cooling: The G8124 uses as little power as two 60 W light bulbs, 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 G8124’s rear-to-front cooling design reduces data center air conditioning costs by having airflow match the servers in the rack. In addition, variable speed fans assist in automatically reducing power consumption.
z
Virtual Fabric can help customers address I/O requirements for multiple NIC’s while also helping reduce cost and complexity. Virtual Fabric for IBM allows for the carving up of a physical NIC into multiple virtual NICs (2 - 8 vNICs) and creates a virtual pipe between the adapter and the switch for improved performance, availability, and security while reducing cost and complexity. (Planned support for late 2010.)
z
VM aware Networking: VMready™ software on the switch helps reduce configuration complexity while significantly improving security levels in virtualized environments. VMready automatically detects virtual machine movement from one physical server to another, and instantly reconfigures each VM’s network policies 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, and Microsoft.
z
Layer 3 functionality: The switch includes Layer 3 functionality, which provides security and performance benefits as inter-VLAN traffic stays within the chassis. 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.
z
Active MultiPath (AMP) effectively doubles bandwidth by allowing all uplink ports to be active/active, eliminating cross-stack traffic and providing up to 900 Gbps aggregate bandwidth between servers. Built-in fault tolerance constant health checking ensures maximum availability.
z
Seamless Interoperability: IBM switches interoperate seamlessly with other vendors' upstream switches. Tolly Reports: Tolly Functionality and Certification: RackSwitch G8000 and G8124 and Cisco Catalyst Interoperability Evaluation.
z
Fault tolerance: These switches learn alternate 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, HotLink, Uplink Failure Detection (UFD), IGMP V3 snooping, and OSPF.
z
Converged fabric: The switch is designed to support CEE and connectivity to FCoE gateways. CEE helps enable clients to combine storage, messaging traffic, VoIP, video, and other data on a common data center Ethernet infrastructure. FCoE helps enable highly efficient block storage over Ethernet for consolidating server network connectivity. As a result, clients can deploy a single server interface for multiple data types, which can simplify both deployment and management of server network connectivity, while maintaining the high availability and robustness required for storage transactions.

Popular configurations
The following sections describe popular configurations.
Virtual Fabric configuration
Note that the support for x3550/x3650 M3 with Emulex adapters is planned for July 23, 2010 and for X5 models is targeted for 4Q 2010.
IBM Virtual Fabric for IBM System x is built using industry standards and is the ideal solution for customers that require more than two NICs per server. Over the past couple of years many clients have seen their I/O requirements per server increase anywhere from 4 to 6 to 8, or even more, NICs per server, especially with the adoption of virtualization. IBM Virtual Fabric allows clients the ability to leverage a virtual NIC approach leveraging 10G Ethernet technology to help reduce cost and complexity while also achieving better performance and more flexibility. For example:
1.
Reduce costs: (acquisition and operating) by using fewer adapters, cables, and upstream switch ports.
2.
Reduce complexity: fewer items to manage, based on industry standards making thing easier to manage with the addition of high availability and better security.
3.
Better performance: significantly more I/O bandwidth per server and lower latency than traditional 1G Ethernet.
4.
Flexibility: the ability to carve up a dual-port 10G adapter into 4 - 8 virtual NICs and create virtual pipes between the adapter and switch for higher availability and security. Not only can customers dynamically allocate I/O bandwidth to each virtual NIC, Virtual Fabric also provides the ability to change those allocations as needed. For example, a customer may have one configuration for workload during the day and another during the evenings. Virtual Fabric has the ability to make those changes on the fly without downtime.
IBM Virtual Fabric (Figure 2) is designed in partnership with BLADE Network Technologies and Emulex. The components needed for this solution are:
