Chapter 2 Installing Cisco MDS NX-OS and Fabric Manager Cisco MDS 9000 Switch Management Send documentation comments to [email protected] Of these five layers of storage network management, Cisco Fabric Manager provides tools for device (element) management and fabric management. In general, the Device Manager is most useful for device management (a single switch), while Fabric Manager is more efficient for performing fabric management operations involving multiple switches. Tools for upper-layer management tasks can be provided by Cisco or by third-party storage and network management applications. The following summarizes the goals and function of each layer of storage network management: • Device management provides tools to configure and manage a device within a system or a fabric. You use device management tools to perform tasks on one device at a time, such as initial device configuration, setting and monitoring thresholds, and managing device system images or firmware. • Fabric management provides a view of an entire fabric and its devices. Fabric management applications provide fabric discovery, fabric monitoring, reporting, and fabric configuration. • Resource management provides tools for managing resources such as fabric bandwidth, connected paths, disks, I/O operations per second (IOPS), CPU, and memory. You can use Fabric Manager to perform some of these tasks. • Data management provides tools for ensuring the integrity, availability, and performance of data. Data management services include redundant array of independent disks (RAID) schemes, data replication practices, backup or recovery requirements, and data migration. Data management capabilities are provided by third-party tools. • Application management provides tools for managing the overall system consisting of devices, fabric, resources, and data from the application. Application management integrates all these components with the applications that use the storage network. Application management capabilities are provided by third-party tools. In-Band Management and Out-of-Band Management Cisco Fabric Manager requires an out-of-band (Ethernet) connection to at least one Cisco MDS 9000 Family switch. You need either mgmt0 or IP over Fibre Channel (IPFC) to manage the fabric. mgmt0 The out-of-band management connection is a 10/100 Mbps Ethernet interface on the supervisor module, labeled mgmt0. The mgmt0 interface can be connected to a management network to access the switch through IP over Ethernet. You must connect to at least one Cisco MDS 9000 Family switch in the fabric through its Ethernet management port. You can then use this connection to manage the other switches using in-band (Fibre Channel) connectivity. Otherwise, you need to connect the mgmt0 port on each switch to your Ethernet network. Each supervisor module has its own Ethernet connection; however, the two Ethernet connections in a redundant supervisor system operate in active or standby mode. The active supervisor module also hosts the active mgmt0 connection. When a failover event occurs to the standby supervisor module, the IP address and media access control (MAC) address of the active Ethernet connection are moved to the standby Ethernet connection. IPFC You can also manage switches on a Fibre Channel network using an in-band IP connection. The Cisco MDS 9000 Family supports RFC 2625 IP over Fibre Channel, which defines an encapsulation method to transport IP over a Fibre Channel network.
