Hardware requirements for using disks in a MetroCluster configuration with V-Series systems

Starting in Data ONTAP 8.2, a MetroCluster configuration with V-Series systems can include native disks only, array LUNs on storage arrays only, or both. There are specific hardware requirements to set up a MetroCluster with V-Series systems with native disks.

Hardware requirements if you are using FibreBridge 6500N bridges

The following hardware is required for using native disks in a MetroCluster configuration with V-Series systems:

  • A pair of V-Series systems
  • FibreBridge 6500N bridges (Data ONTAP 8.2 and later) or, for stretch MetroCluster configurations only, SAS optical cables (Data ONTAP 8.2.1 and later)
    Note: For V-Series systems, support for SAS optical cables does not start until Data ONTAP 8.2.1.

Prior to Data ONTAP 8.2, MetroCluster configurations with V-Series systems could not include V-Series systems that used disks. In Data ONTAP 8.2, for a MetroCluster configuration to include both disks and array LUNs, all systems in the configuration must be V-Series systems. Platforms released in 8.2.1 and later can include both array LUNs and disks in a MetroCluster configuration. However, no MetroCluster configurations can include both V-Series systems and FAS systems.

The following hardware is required for using native disks in a MetroCluster configuration with V-Series systems:

  • Four FibreBridge 6500N bridges: two FibreBridge 6500N bridges per stack of disk shelves, distributed across two sites

    The disk shelves in the MetroCluster configuration are those supported by the FibreBridge 6500N bridges.

  • Supported firmware for the FibreBridge 6500N bridges, as shown in the Interoperability Matrix at support.netapp.com
  • For a fabric-attached MetroCluster configuration, four switches

    The switches must be designated in the Interoperability Matrix at support.netapp.com as being supported for a MetroCluster configuration.

    Note: If the fabric-attached MetroCluster configuration also accesses LUNs on the storage arrays, these same switches are used for array LUN access as well. A stretch MetroCluster configuration that also uses array LUNs would use four switches to access the array LUNs, but the switches would not be used to access the disks.

See the Configuring a MetroCluster system with SAS disk shelves and FibreBridge 6500N bridges for information about how to connect the FibreBridge 6500N and the disk shelves.

Required types of connections between a V-Series system and a FibreBridge 6500N bridge

Fabric-attached Switches
Stretch Direct FC connections

Hardware requirements if you are using SAS optical cables

SAS optical cables can be used to cable SAS disk shelves in a stretch MetroCluster system to achieve greater connectivity over distance than is possible with SAS copper cables. SAS optical cables can be used in a new system installation or in an existing system in which you want to replace the SAS copper cables and FibreBridge 6500N bridges. SAS optical cables are supported for use with V-Series systems starting in Data ONTAP 8.2.1.

See Configuring a stretch MetroCluster system with SAS disk shelves and SAS optical cables on the NetApp Support Site at support.netapp.com for hardware requirements and procedures for installing a new system with SAS optical cables or replacing FibreBridge 6500N bridges with SAS optical cables.
