Send document comments to [email protected] . This preface describes the organization and conventions of the Cisco UCS Server Configuration. My NetApp From the Ground Up series of posts have proven to be quite popular. Though I still have quite a lot of posts left to write in that series. Cisco UCS Installation and Basic Config. Below you'll find This is a pretty lengthy blog post, so if you'd like it musicmarkup.info format, click here.

Gain an overview of the main components of Cisco UCS: unified fabric, unified management, and unified computing resources. Cisco UCS Manager Getting Started Guide Overview 3. Cisco UCS Manager User Documentation 4. Fundamentals of Cisco Unified Computing. Gain an overview of Cisco UCS Manager fundamentals and best practices and learn the most direct path to working in a stateless-server SAN-boot environment.
I wanted to post this as a general guideline for those new to UCS who may be setting up their first lab or production environments. Based on how your environment is set up and the type of connectivity you require, the cabling could be much different than what is pictured above. Each switch is then connected to each storage processor. You will then be presented with the following menu items in bold , with input in green:. Enter the configuration method.
Ensure your filter is set to ALL and you should have a backup option, as shown in Figure 4. Refer to Cisco documentation for more information on backing up and restoring the UCS configuration.
Better safe than sorry! Tintri recommends you change the default maintenance policy to User Ack, shown in Figure 5. This option will prompt you to confirm each server is safe to reboot in advance.
Each VMstore will be connected directly to the FI. You will need four ports per VMstore being configured: two ports to connect to the A fabric and two ports to connect to the B fabric for each controller in a VMstore.
Instructions provided within this document all imply that End-Host Mode.
Choose two unused Ethernet Ports from the list. Selecting more than one VLAN provides greater flexibility for future configuration needs. Tintri recommends not doing so. Complete the same steps shown above for the second port on Fabric A. It is not necessary to create the VLAN. It will already exist in the VLANs list as a result of creating it in the prior step.
Switch to Fabric B and repeat the process for the two ports on Fabric B. If possible, use the same port numbers as used on Fabric A.
After several discussions with Cisco support, and validation in our own lab, we learned there is no maximum limit of appliance ports. The only limitation is the number of physical FI ports and FI port licenses you have available.
We had 4 VMstores configured as appliance ports in our lab 10 total ports per fabric. While you can add as many appliance ports as you like, beyond several VMstores, you may want to consider dedicated IP Storage switches to connect your VMstores to.
Each pin Group should be configured to designate the port-channel that is used to uplink to the upstream switch. What this will do is mark the vNIC exposed to the host as down in the event the FI is isolated from the rest of the network.
This can be done by configuring the ports the FIs are uplinked to as Trunk ports. Refer to Cisco documentation for full configuration details and best practices.
See the Jumbo Frames section in the Appendix for more information and the design rationale. A hard copy of the guide should be included in your VMstore packaging, but keep in mind that newer versions may be available. The critical thing to note is that one port from each VMstore controller is connected to Fabric A and the other port is connected to Fabric B as illustrated in Figure 8.
We did not cover these in detail in class so I am still a little fuzzy on templates. I plan to address the questions I outlined in my first UCS for Dummies post and explain some of my final thoughts on how, where, and why UCS fits in the datacenter.

Gestalt — noun an organized whole that is perceived as more than the sum of its parts. Create Service Profiles to use Pools The steps from the lab explain the use of the pools created. Associate your service profile by choosing the blade server pool, rather than a specific blade.
Summary Matching the assigned configurations from the storage and network administrators is crucial, but once in place the UCS server admins handle all inbound connectivity set up.

About Gestalt IT. Unlike the VMware Workstation software, ESX and ESXi run directly on the system hardware without the need for any other software called Bare Metal , and provide the necessary hypervisor functions to host several guest operating systems such as Windows or Linux on the physical server.
Cisco currently produces the following series. Virtual machines can be moved from one physical chassis to another, applications may be moved between virtual machines, and management may even be conducted remotely from an iPhone using SiMU — Simple iPhone Management of UCS.
A key benefit is the concept of Stateless Computing. Each compute node has no set configuration. This allows for consistent configuration and ease of re-purposing. A new profile can be applied within a matter of minutes. As they say, a picture is worth a thousand words.
The diagram below from this Define the Cloud post illustrates the information contained in this post. Never fear though, this series of posts will leave you feeling like a UCS expert: As always, if you have any questions or have a topic that you would like me to discuss, please feel free to post a comment at the bottom of this blog entry, e-mail at will oznetnerd.
