Direct connect and fabric connect configurations

In a direct connect or fabric connect configuration, two host systems are each connected by two connections to both of the controllers in a storage array. SANtricity Storage Manager, including multipath driver support, is installed on each host.

Not every operating system supports this configuration. Consult the restrictions in the installation and support guide specific to your operating system for more information. Also, the host systems must be able to handle the multi-host configuration. Refer to the applicable hardware documentation.

In either a direct connect or fabric connect configuration, each host has visibility to both controllers, all data connections, and all configured volumes in a storage array.

The following conditions apply to these both direct connect and fabric connect configurations:

  1. Two Host Systems, Each with Two SAS, Fibre Channel, iSCSI, or InfiniBand Host Bus Adapters
  2. SAS, Fibre Channel, iSCSI, or InfiniBand Connections with Two Switches (Might Contain Different Switch Configurations)
  3. Storage Array with Two Controllers
