Cisco UCS is designed to be programmable and self-

integrating. A server’s entire hardware stack, ranging from the

server firmware and settings to network profiles, is configured through model-based management. With Cisco

VICs, even the number and type of I/O interfaces is programmed dynamically, making every server ready to power

any workload at any time.

With model-based management, administrators manipulate a model of a desired system configuration and
associate the model’s service profile with hardware resources, and the system configures itself to match the model.

This automation accelerates provisioning and workload migration with accurate and rapid scalability. The result is

increased IT staff productivity, improved compliance, and reduced risk of failures due to inconsistent

configurations.

Cisco UCS Service Profiles

Traditional Provisioning Approach

A server’s identity is made up of numerous properties, such as UUID, boot order, Intelligent Platform Management

Interface (IPMI) settings, BIOS firmware, BIOS settings, RAID settings, disk scrub settings, number of NICs, NIC

speed, NIC firmware, MAC and IP addresses, number of HBAs, HBA WWNs, HBA firmware, FC fabric

assignments, QoS settings, VLAN assignments, and remote keyboard/video/monitor. The extensive list of

properties means multiple points of configuration that give a server its identity and make it unique within the data

center. Some of these parameters are linked to the hardware of the server itself (such as the BIOS firmware

version, BIOS settings, boot order, FC boot settings, etc.), while some settings are linked to the network and

storage switches (such as VLAN assignments, FC fabric assignments, QoS settings, and access control lists

[ACLs]). Figure 10 shows the traditional provisioning approach employed in the data center.
