You are configuring a service profile for a Cisco UCS server that has been configured with two converged network adapters.
What is the maximum number of vHBAs that can be configured on this server if no vNICs are configured?
- four
- six
- eight
- two
If no virtual network interface cards (vNICs) are configured on the Cisco Unified Computing System (UCS) server in this scenario, up to four virtual host bus adapters (vHBAs) could be configured. A converged network adapter is a single unit that combines a physical host bus adapter (HBA) and a physical Ethernet network interface card (NIC). A Cisco converged network adapter typically contains two of these types of ports. Therefore, if no vNICs are configured on the device, it is possible for the Cisco UCS server in this scenario to be configured with four vHBAs.
Although it is possible to configure two vHBAs on the Cisco UCS server in this scenario, it is possible to configure a maximum of four vHBAs because no vNICs have been configured. If two vNICs had been configured in this scenario, it would be possible to configure a maximum of two vHBAs.
It is not possible to configure six or eight vHBAs, because the Cisco UCS server in this scenario is not configured with more than two converged network adapters. In order to support a higher maximum number of vHBAs, the Cisco UCS server in this scenario would need to be configured with a greater number of physical HBAs or converged network adapters.
