Youdo not need to configure these hardware components directly.
Server Identity Management through Service Profiles
Youcan use the network and device identities burned into the server hardware at manufacture or you can use
identitiesthat you specifyin theassociated service profileeither directly or through identity pools, such as
MAC,WWN, and UUID.
Thefollowing areexamples of configurationinformation that you caninclude in aservice profile:
• Profile name and description
• Unique server identity (UUID)
• LAN connectivity attributes, such as the MAC address
• SAN connectivity attributes, such as the WWN
Operational Aspects configured by Service Profiles
Youcan configure some of the operational functions for a server in a service profile, such as the following:
• Firmware packages and versions
• Operating system boot order and configuration
• IPMI and KVM access
vNIC Configuration by Service Profiles
AvNIC is a virtualized network interface that is configured on a physical network adapter and appears to be
aphysical NIC to the operating system of the server. The type of adapter in the system determines how many
vNICsyou can create. For example, a converged network adapter has two NICs, which means you can create
amaximum of two vNICs for each adapter.
AvNIC communicates over Ethernet and handles LAN traffic. At a minimum, each vNIC must be configured
witha name and with fabric and network connectivity.
vHBA Configuration by Service Profiles
AvHBA is a virtualized host bus adapter that is configured on a physical network adapter and appears to be
aphysical HBA to the operating system of the server. The type of adapter in the system determines how many
vHBAsyou can create. For example, a converged network adapter has two HBAs, which means you can
createa maximum of two vHBAs for each of those adapters. In contrast, a network interface card does not
haveany HBAs, which means you cannot create any vHBAs for those adapters.
AvHBA communicates over FCoE and handles SAN traffic. At a minimum, each vHBA must be configured
witha name and fabric connectivity.
Service Profiles that Override Server Identity
Thistype of service profile provides the maximum amount of flexibility and control. This profile allows you
tooverride the identity values that are on the server at the time of association and use the resource pools and
policiesset up in Cisco UCS Manager to automate some administration tasks.
Youcan disassociate this service profile from one server and then associate it with another server. This
re-associationcan be done either manually or through an automated server pool policy. The burned-in settings,
