SAN Administration Guide

  • Deciding whether to use the SAN Administration Guide
    This guide describes basic SAN host provisioning. It shows you how to configure and manage LUNs, igroups, and targets using the iSCSI and FC protocols, and namespaces and subsystems using the NVMe/FC protocol.
  • Setting up and managing LUNs for FC and iSCSI
    The FC protocol and iSCSI protocol both provision storage through the use of LUNs. After you have setup your LUNs, you can perform various management tasks, such as increasing or decreasing the size of a LUN.
  • Setting up namespaces for NVMe
    To set up the NVMe protocol in your SAN environment, you must configure an SVM for NVMe, create namespaces and subsystems, configure an FC-NVMe LIF, and then map the namespaces to the subsystems.
  • SAN protocol management
    You can manage your specific SAN protocol in various ways.
  • Managing LIFs for all SAN protocols
    LIFs can be removed from port sets, moved to different nodes within a storage virtual machine (SVM), and deleted.
  • Data protection methods in SAN environments
    You can protect your data by making copies of it so that it is available for restoration in the event of accidental deletion, application crashes, data corruption, or disaster. Depending on your data protection and backup needs, ONTAP offers a variety of methods that enable you to protect your data.
  • Considerations for SAN configurations in a MetroCluster environment
    You must be aware of certain considerations when using SAN configurations in a MetroCluster environment.
  • SAN Concepts
    In iSCSI networks and FC fabrics, storage systems are targets that have storage target devices. For iSCSI and FC, the storage target devices are referred to as LUNs (logical units). For Non-Volatile Memory Express (NVMe) over Fibre Channel, the storage target devices are referred to as namespaces. You configure storage by creating LUNs for iSCSI and FC or by creating namespaces for NVMe. The LUNs or namespaces are then accessed by hosts.
