  • Page 511: Fibre Channel Connectivity

    11.5 Fibre Channel connectivity Fibre Channel (FC) is an open, technical standard for networking which incorporates the “channel transport” characteristics of an I/O bus, with the flexible connectivity and distance characteristics of a traditional network. Due to its channel-like qualities, hosts and applications see storage devices attached to the SAN as though they are locally attached storage.
  • Page 512: The Concept Of Layers

    Logically, a source and target node must use the same protocol, but each node can support several different protocols or data types. In the IBM Flex System Enterprise Chassis the compute nodes are the initiators with IBM Flex System V7000 Storage Node being the target.
  • Page 513 Physical and signaling layers The physical and signaling layers include the three lowest layers: FC-0, FC-1,and FC-2: Physical interface and media: FC-0 The lowest layer, FC-0, defines the physical link in the system, including the cabling, connectors, and electrical parameters for the system at a wide range of data rates. This level is designed for maximum flexibility, and allows the use of a large number of technologies to match the needs of the configuration.

    The point-to-point topology is used within the IBM Flex System Enterprise Chassis switch between the compute node and the I/O Module FC switch.

    For this reason, SAN zoning rules must be applied and the IBM Flex System FC3171 8Gb SAN Switch in each slot must be zoned, as follows: In each fabric, create a zone with just the four IBM Flex System V7000 Storage Node two from each node canister.
  • Page 517 2. When you connect internal switches to an external SAN, to optimize bandwidth and for the best high availability, use trunking (also known as port channel). 3.

It can connect to an external FC SAN fabric as shown in Figure 11-38 on page 495.
  • Page 528 The Transparent Mode option will only be considered when connecting the FC3171 8Gb SAN Switch to an external SAN fabric, as previously mentioned, it will be used for IBM Flex System V7000 Storage Node to connect and manage external storage controllers. Another option is to use the IBM Flex System FC3171 8Gb SAN Pass-thru switch which does not have full switch functionality and operates as a gateway device only using NPIV.
  • Page 529: Storage Area Network Summary

    Major determining factors in this choice of SAN include the external connectivity whether FC or type of Ethernet. We would favor FCoE and FC over iSCSI in the enclosed IBM Flex System Enterprise Chassis environment, as TCP/IP within the protocol layer is unnecessary in this environment.

    In this section, we describe the procedure to monitor the system status and the health. 13.3.1 Using FSM for status and health IBM Flex System Manager provides a set of tools that you can use to monitor and manage the status and health of resources in your environment from a single interface.
  • Page 605 You can display this information using one of the System Status and Health tasks, by navigating to a specific resource in IBM Flex System Manager, or by using the command-line interface. After the first discovery of the resources, IBM Flex System Manager automatically monitors the system and its resources, as shown in Figure 13-6.
  • Page 606: System Status And Health Tasks

    Specifically, the Health Summary task displays information about the resources that IBM Flex System Manager has discovered. You can customize the content that is displayed on the System Status and Health pages with information that is specific to your business processes and organizational structure.
  • Page 607 The Problems task lists only those elevated status set entries that are problem status set entries that have been reported to IBM Flex System Manager. The data listed here is a subset of what is listed on the Active Status page. From the Problems page, you can navigate to, display, and manage these status set entries.
