You are configuring a service profile for a Cisco UCS server that contains four physical NICs but no physical HBAs.
How many vHBAs can be configured for this server?
- none
- eight
- two
- four
No virtual host bus adapters (vHBAs) can be configured for a Cisco Unified Computing System (UCS) server that contains four physical network interface cards (NICs) but no physical host bus adapters (HBAs). A Cisco UCS can be configured with the number of vHBAs that corresponds to available physical HBAs on the physical adapters that are installed in the device. Similarly, a Cisco UCS server can be configured with the number of virtual NICs (vNICs) that corresponds to available physical NICs on the server.
It is not possible to configure two vHBAs for the Cisco UCS server in this scenario. In order to configure two vHBAs, the server would need to be configured with one or more adapters that each contains one or more physical HBAs. For example, a Cisco converged network adapter typically contains two physical ports. Therefore, a Cisco UCS server that is configured with a single converged network adapter could be configured with two vHBAs. A converged network adapter is a single unit that combines a physical HBA and a physical Ethernet NIC. A Cisco converged network adapter typically contains two of these types of ports.
It is not possible to configure four vHBAs for the Cisco UCS server in this scenario. To configure four vHBAs, the UCS server would need to be configured with adapters that contain up to four physical HBAs.
It is not possible to configure eight vHBAs for the Cisco UCS server in this scenario. To configure eight vHBAs, the UCS server would need to be configured with adapters that contain up to eight physical HBAs.
