Requirements for shared SAN configurations

Shared SAN configurations are defined as hosts that are attached to both ONTAP storage systems and other vendors' storage systems. Accessing ONTAP storage systems and other vendors' storage systems from a single host is supported as long as several requirements are met.

For all of the host operating systems, it is a best practice to use separate adapters to connect to each vendor's storage systems. Using separate adapters reduces the chances of conflicting drivers and settings. For connections to an ONTAP storage system, the adapter model, BIOS, firmware, and driver must be listed as supported in the Lenovo Storage Interoperation Center (LSIC).

You should set the required or recommended timeout values and other storage parameters for the host. You must always install the Lenovo software or apply the Lenovo settings last.

  • For ESX, you should apply host settings by using Virtual Storage Console for VMware vSphere.

  • For Linux, you should apply the values from the Linux Host Utilities version that is listed in the Lenovo Storage Interoperation Center (LSIC) for your configuration.

  • For Windows, you should install either the Data ONTAP DSM for Windows MPIO or the Windows Host Utilities version that is listed in the Lenovo Storage Interoperation Center (LSIC) for your configuration.
