  • Page 17: Chapter 1 Svc Product Overview

    The combined SVC storage software along with the Cisco MDS 9000 Series CSM is delivered as a feature of the Cisco MDS 9000 Family. The SVC software runs on a clustered pair of CSMs within the switch. Based on virtualization technology, this solution is designed to support a virtualized pool of storage from the storage subsystems attached to a SAN.

    Provides simple migration of storage. Provides a single set of copy services. • SVC Features This section explains the features provided by the combined SVC storage software and the Cisco MDS 9000 Series CSM solution. A central point for volume management control •...
  • Page 19 • High availability Like all other Cisco MDS 9000 Family modules, the CSM is hot-swappable and fully integrates into the Cisco MDS 9000 high availability architecture. The Cisco MDS 9000 SAN-OS software architecture offers an unparalleled level of availability including automatic restart of failed supervisor processes and fabric level availability via Cisco PortChannel capability which allows 16 physical links to be aggregated into one logical interface.

For users who prefer a common interface for both SAN and Volume management, the Cisco SAN-OS CLI includes the full suite of capabilities necessary to manage your virtual storage environment from the SAN-OS command line.

  • Page 21: Getting Started

    The chapter explains the tasks required to set up and configure each building block of your system to run SVC for Switches. You will be performing these tasks using one or more Cisco MDS 9000 Family switches for setup and configuration. You may wish to have your Cisco and IBM documentation handy for reference to more detailed procedures.

    In order for SVC to virtualize the back-end storage to hosts, you must ensure that the hosts do not directly access the storage. You can separate hosts or disks using the concept of VSANs. The VSAN feature is specific to Cisco MDS 9000 Family switches. Alternatively, you can also use zones to separate hosts or disks.

    Virtualization is the process of creating a pool of storage that can be split into VDisks. VDisks are visible to the host systems that use them and provide a common way to manage SAN storage. VDisks in the Cisco MDS 9000 Family use one of three virtualization policies: striped, sequential, or image. Striped When a VDisk is created using a striped policy its extents are allocated from the specified ordered list of MDisks.

  • Page 82: Prerequisites To Replacing A Csm

    Replacing a CSM in the Same Slot If a CSM is replaced by another CSM in the same slot in any switch in the Cisco MDS 9500 Series or in a Cisco MDS 9216 Switch, the same nWWNs and pWWNs are automatically assigned for both interfaces on the new CSM.

  • Page 83: Replacing A Csm In A Different Slot

    The old nWWNs and pWWNs will be lost from the system and never reassigned for any purpose in that chassis. Replace the new CSM in the same slot as directed in the Cisco MDS 9216 Switch or the Cisco MDS 9500 Step 3 Series Hardware Installation Guide.

    The Node ID of the replacement node is different from the node ID of the replaced node. Use the SDD management tool on the host systems to verify that all paths are online. Step 4 Cisco MDS 9000 Family SAN Volume Controller Configuration Guide 8-12 78-16119-01, Cisco MDS SAN-OS Release 1.3...

    Caching Services Module (CSM) module. The SPAN feature is specific to switches in the Cisco MDS 9000 Family. It monitors network traffic though a interface. Traffic through any SVC interface can be replicated to a special port called the SPAN destination port (SD port).

    All SVC nodes must be able to use the same preferred target controller port for a given Mdisk. In a redundant, dual fabric configuration, the Cisco MDS Inter-VSAN Routing (IVR) feature must be used in order to satisfy these basic SVC requirements. IVR provides the same benefit of keeping the two fabrics separate while providing the connectivity required to implement SVC.
