You can use your Unitrends appliance to back up and recover Cisco UCS service profiles and related configuration objects. In the event of a disaster, you can use this feature to quickly recover your service profiles, greatly reducing the recovery time objective (RTO) of reconfiguring your network and servers.
The Cisco UCS environment provides a “virtual chassis” that enables you to create and assign hardware profiles to individual logical servers. You can then bring up the logical server on dedicated hardware that you can easily migrate to another server in the case of hardware failure, or migrate between servers that do not require 24/7 up-time for efficient hardware reuse.
For UCS B-Series blade servers and C-Series rack-mount servers, allocation of UCS resources and hardware is managed at the domain level by the Cisco UCS manager. Each server in the UCS is a “logical server” that utilizes various resources as defined in the server’s service profile, and there is a one-to-one relationship between a service profile and a physical server. The service profile references hardware requirements, such as hardware identifiers, firmware, state, configuration, connectivity and behavior, but is completely separate from the physical UCS environment. Once a service profile is instantiated and associated with a given blade, rack-mount server, or server in a server pool, you configure a PXE server or map a bootable ISO image to the virtual-media CDROM drive to install the desired hypervisor or operating system (OS). See the Cisco document Cisco UCS Manager Configuration Common Practices and Quick Start Guide for details.
A service profile may be associated with a template and various policies. A service profile template can be used to quickly create additional service profiles. Policies can be used to enforce rules to help ensure consistency. For example, a boot policy defines how a server boots, including boot devices, methods, and boot order.
Because service profiles are essential to managing the servers in your Cisco UCS environment, it is important that you protect these configurations. Unitrends leverages native Cisco UCS data protection for profile backup and recovery, utilizing the Cisco XML API. Unitrends UCS profile backups capture all supported profiles, templates, pools, and policies in your UCS environment. For a description of each supported object that may be included in the UCS profile backup, see Identifying files in UCS service profile backups. Once you have a UCS profile backup, you can easily recover these items to quickly spin up your Cisco UCS environment in the event of a disaster, greatly reducing RTO.

The following objects are not included in Unitrends UCS profile backups: BIOS defaults, IPMI access policies, management firmware policies (deprecated, replaced by host firmware packages), and iSCSI authentication profiles. |

UCS profile backups capture only service profiles, templates, pools, and policies. To protect UCS servers themselves, add them as assets to the Unitrends appliance and schedule file-level backups. |
