CCIE Data Center 350-080 V1.0 WRITTEN EXAM ESSENTIALS – Cisco UCS Components and Architecture

Exam Questions

 

In a series of blog posts, I will go over each of the Cisco’s official blueprint sections for CCIE DC 350-080 V1.0 written exam and call out the very essential topics and knowledge base that are must-know for passing the exam. Please note that all of our CCIE Written Exam Cert Study Guides include similar exam essentials at the end of each chapter to reinforce key concepts for our readers.

I hope that you find them useful!

  • Cisco UCS provides XML API, CLI, SNMP, SMASH CLP and CIM-XML as standard interfaces to integrate it with industry standard management tools
  • 16GB DIMMs are only supported on two B-class chassis i.e. B200 and B440. B250 doesn’t support 16GB DIMMs and is a discontinued product at this time
  • If you use 1333-MHz DIMMs with an E5620 CPU (which can support up to 1066-MHz DIMMs), the DIMMS will be clocked at the lower speed of 1066 MHz
  • UCS C260 supports memory extension technology, which is a Cisco’s patented technology that enables up to 384 GB of memory on a single serve
  • Each CPU in a Cisco UCS B250 blade server supports 2 logical DIMMs (up to 8 physical DIMMs) and 3 channels.
  • Power capping is the capability to limit the power consumption of a system, be it a blade server or a rack server, to some threshold that is less than or equal to the system’s maximum rated power.
  • Power capping can help reduce data center cooling costs
  • Cisco UCS fabric failover is an important feature because it reduces the complexity of defining NIC teaming software for failover on the host. It does this transparently in the fabric based on the network property that is defined in the service profile.
  • Scrub policy determines what happens to local data (disk) and to the BIOS settings on a server during the discovery process and when the server is disassociated from a service profile.
  • You can integrate Cisco UCS C-Series Rack-Mount Servers with Cisco UCS Manager in either one of the following setup:
    • Cluster setup: Using two fabric extenders (FEXes) to connect the C-Series Rack-Mount Server with two fabric interconnects.
    • Non-cluster setup: Connecting the C-Series Rack-Mount Server with one FEX and one FI.
  • Fault suppression allows you to suppress SNMP trap and Call Home notifications during a planned maintenance time. You can create a fault suppression task to prevent notifications from being sent whenever a transient fault is raised or cleared.
  • These policies define which causes and types of faults you want to suppress. Only one policy can be assigned to a task. The following policies are defined by Cisco UCS Manager:
    • default-chassis-all-maint—Suppresses faults for the chassis and all components installed into the chassis, including all blade servers, power supplies, fan modules, and IOMs.
    • This policy applies only to chassis.
    • default-chassis-phys-maint—Suppresses faults for the chassis and all fan modules and power supplies installed into the chassis.
    • This policy applies only to chassis.
    • default-fex-all-maint—Suppresses faults for the FEX and all power supplies, fan modules, and IOMs in the FEX.
    • This policy applies only to FEXes.
    • default-fex-phys-maint—Suppresses faults for the FEX and all fan modules and power supplies in the FEX.
    • This policy applies only to FEXes.
    • default-server-maint—Suppresses faults for blade servers and/or rack servers.
  • Each adapter in Cisco UCS is a dual-port adapter that connects to both fabrics (A and B). The two fabrics in Cisco UCS provide failover protection in the event of planned or unplanned component downtime in one of the fabrics. Typically, host software-such as NIC teaming for Ethernet and EMC PowerPath or multipath I/O (MPIO) for Fibre Channel-provides failover across the two fabrics
