Support for Stateless Deployment

Stateless deployments are dependent on the Host Bus Adapter (HBA) cards available in Dell PowerEdge

servers. A server may have HBA cards manufactured by one or more vendors. Stateless deployments may

or may not be supported on a server depending on the HBA card vendor. The following table provides

information about the support for stateless deployment tasks based on the HBA card vendor.

NOTE: Before you preform stateless deployment, ensure that the HBA cards have the latest

firmware version installed.

NOTE: For the list of HBA card types that support stateless deployment, see “Supported cards for

I/O Identity Optimization” in the iDRAC User’s Guide at Delltechcenter.com/iDRAC.
