Customers can order Fibre Channel (FC) host bus adaptors (HBA) with their VxRail for external storage. FC storage can be configured to complement local VxRail cluster storage. Common use cases for external storage are customer’s desire to continue to use their existing storage array as a secondary storage to VxRail, or they are looking for a method to migrate data from their FC storage to VxRail vSAN datastores. VxRail does not provide lifecycle management to the FC HBA. Customers will need to manage it via vCenter Server.
Using a FC HBA, customer can connect to storage arrays that is supported by the HBA card and validated by VMware. However, Dell EMC will only provide support for connection of the HBA to a Dell EMC storage array (i.e. Dell Compellent, Clariion/VNX/Unity, Symmetrix DMX, Symmetrix VMAX/PowerMAX, and XtremIO) that is qualified by eLab.
When configuring external storage via the FC HBA, customer is allowed to install VM/VIB/drivers to operationalize the use of the external storage as required. The customer is responsible for maintaining and updating it. Customers can install multiple HBAs if there are slots available on the PCIe bus.
