The Cisco UCS C-Series Rack Mount servers are designed to operate in both; as part of Cisco Unified Computing System or in standalone environments. When used as part of UCS these C-Series Rack servers function the same as the B-Series Blade servers; i.e. they are configured and managed using UCS Manager and service profiles are applied to them. When used in standalone environments, C-Series Rack servers can be used with Cisco Nexus switches which support features like Cisco VN-Link technology or can be used with other Cisco or third party switches. This gives the organization a greater flexibility in deploying the UCS C-Series Rack servers.The other advantage or Rack servers is that it enables the organization to deploy systems on time that best meet their growth and budget.
C-Series Rack server Overview

Cisco Integrated Management Controller (CIMC) is used for management/monitoring of C-Series Rack servers. CIMC provides options like WebGUI, CLI and IPMI for management/monitoring tasks. CIMC runs on a separate chip on the C-Series servers and thus is able to provide services in case of any major hardware failure or system crash. CIMC also does user management tasks and supports user access levels of Admin (Full access), User/Operator (can change host features but not CIMC) and Read Only (can only see information). CIMC uses IPMI to monitor thermal and voltage sensors in the servers. CIMC is useful for initial configuration of the server and troubleshooting any problems in server operation; however CIMC can not be used for tasks like deploying an OS, deploying software patches, install software applications and manage external storage on SAN or NAS.
Recently, I have tried to deploy APIC-dk126.96.36.199e on vCenter but after initial configuration, the system does not accept the user and password, plus the Web interface is not reachable! Moreover, I waited hours thinking that maybe the services need time to ...
Hello, while checking an ACI fabric from a customer I noticed there are no interface policy groups assigned to the required interfaces. Also there is no VMM integration. The hosts are classical connected to the fabric. The interfaces are up...
Experts,I'm totally confused by the (rather pathetic) HyperFlex M6 LFF Specifications.I'm particularly confused about this (taken from the Overview)The server accommodates up to 12 front facing SAS-only LFF drives, up to 4 mid-plane SAS-only LFF drives, a...
Hi All, Can some one please explain me what is the use of different VTEP Pool (IP) in each multipod site.as i know leaf and spine get tep IP addresses in each pod from Seed pod (Primary POD) then what is the use of different TEP pool in all multipod ...
Hello,I've received a microsegmentation requirement. It appears we're to take a base EPG and create distinct groups of hosts. The hosts are in the same IP subnet and same BD. I intend to create three micro-EPGs and utilize the IP Address attributes, for e...
