IBM Flex System FC3171 8Gb SAN Switch and

Pass-thru

IBM Redbooks Product Guide

The IBM Flex System™ FC3171 8Gb SAN Switch is a full-fabric Fibre Channel component with expanded

functionality. The SAN switch supports high speed traffic processing for IBM Flex System configurations,

and offers scalability in external SAN size and complexity, and enhanced systems management

capabilities. The IBM Flex System FC3171 8Gb Pass-thru supports a fully interoperable solution for

seamless integration of the Fibre Channel initiators to an existing fabric. The pass-thru module uses

industry-standard N_Port ID virtualization (NPIV) technology to provide a cost-effective connectivity

solution for the IBM Flex System chassis.

Figure 1 shows the switch module.

Did you know?

These switch modules are licensed to operate in either full-fabric mode or intelligent pass-thru

mode.These modules allow IBM Flex System integration with any open-standards-based SAN, whether

the module has enterprise open-system fabric functionality using the full-fabric mode, or the module has

transparent switching functionality using the intelligent pass-thru mode.

IBM Flex System, a new category of computing and the next generation of Smarter Computing, offers

intelligent workload deployment and management for maximum business agility. This chassis delivers

high-speed performance complete with integrated servers, storage, and networking for multi-chassis

management in datacenter compute environments. Furthermore, its flexible design can meet the needs of

varying workloads with independently scalable IT resource pools for higher utilization and lower cost per

workload. While increased security and resiliency protect vital information and promote maximum uptime,

the integrated, easy-to-use management system reduces setup time and complexity, providing a quicker

path to ROI.

Benefits The switch offers the following key benefits:  Easy to install and manage On-board GUI — no software to load. Just point a web browser at any switch and manage the entire fabric from that location. No matter what your level of expertise, the web-based QuickTools interface has all you need for basic fabric management.  Fast, reliable performance The switch provides uncontested “wire speed” bandwidth at every port — a total of 320 Gbps per switch with less than 4 ms fabric latency.

The connections between the adapters installed in the compute nodes to the switch bays in the chassis are shown diagrammatically in the following figure. The figure shows both half-wide servers, such as the x240 with two adapters, and full-wide servers, such as the p460 with four adapters. Figure 3. Logical layout of the interconnects between I/O adapters and I/O modules The IBM Flex System FC3171 8Gb SAN Switch and Pass-thru can be installed in bays 1, 2, 3, and 4 of the Enterprise chassis.

The adapters are installed in slots in each compute node. The following figure shows the locations of the slots in the x240 Compute Node. The positions of the adapters in the other supported servers are similar. Figure 4.

Popular configurations The following figure shows use of the IBM Flex System FC3171 8Gb SAN Switch to route two ports on the adapter card installed in slot 2 of the compute node. Each compute node has two 8 Gb FC ports, and two FC3171 switches are installed in bays 3 and 4 of the Enterprise Chassis. The connections between the adapter card and the switches are internal to the chassis. No cabling is needed. Figure 5.
