![]() ![]() from a pool of resource configured inside UCS Manager. Service Profile Which Overrides Server Identity: This type of service profile exhibits the true nature of stateless computing as it uses identity parameters like MAC addresses, WWPN, BIOS version, Disk Configuration, Firmware maintenance, etc. These types of service profiles cannot be moved from one server to another as they would require changes to be in certain parameters at the time of porting. Since we use burned-in values of the servers, it pretty much justifies that this type of service profile is more suitable for 1:1 mapping configuration. Service Profile Which Inherits Server Identity: These type of service profiles uses the burned-in factory settings and values like MAC address, WWPN, BIOS version, etc. The configuration constructs are totally independent of the underlying hardware. You can mix and match servers of different generations/models in a UCS environment. The Service Profiles are stored in the Fabric Interconnects and then pushed to the servers in a UCS domain. You can abstract all these key identifiers and play around by packaging them in one profile and moving this pre-packaged identity from one blade server to another, this is called stateless computing. A server’s identity is all about its MAC Addresses for vNICs, WWPN for vHBAs, UUID, etc. UCS Manager helps us achieve stateless computing with one of its key components – Service Profiles. A single UCS domain can grow up to as many as 20 blade chassis. The number of blade chassis that can be managed by an instance of UCS Manager, draws the boundary of the UCS domain. The UCS Manager software which happens to be the brain of Cisco’s SDDC solution sits inside these Fabric Interconnects. What exactly is a UCS domain? – Fabric Interconnects which is our TOR switch for blade chassis, defines the UCS domain. UCS Manager allows you to configure/manage your blade chassis, blade servers, rack servers, etc. Cisco’s UCS Manager is a Software-Defined Data Center (SDDC) solution that provides us a single pane of glass to provide simplified management of our servers and chassis. ![]()
