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 medical-site.info format, click here.

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. X IPv4 address of the default gateway : X. X Cluster IPv4 address : X. X Configure the default domain name? Once again, you will be presented with the following menu items: Enter the configuration method. This Fabric interconnect will be added to the cluster. For instance, in the drawing displayed earlier each IOM had four connections to its associated Fabric Interconnect. This policy is essentially just specifying how many connections need to be present for a chassis to be discovered. If one source fails which causes a loss of power to one or two power supplies , the surviving power supplies on the other power circuit continue to provide power to the chassis.

For instance, in the drawing displayed earlier each IOM had four connections to its associated Fabric Interconnect. This policy is essentially just specifying how many connections need to be present for a chassis to be discovered.

If one source fails which causes a loss of power to one or two power supplies , the surviving power supplies on the other power circuit continue to provide power to the chassis. Both grids in a power redundant system should have the same number of power supplies. Slots 1 and 2 are assigned to grid 1 and slots 3 and 4 are assigned to grid 2.

Then give the port channel a name and select the appropriate ports and select finish: Select the SAN port channel and ensure that it is enabled and set for the appropriate speed: Updating Firmware What follows are instructions for manually updating firmware to the 2.

Systems that are currently in production will follow a slightly different set of steps e.

After the 2. This is accomplished by using the concept of Service profiles; which is like software definition of a server. The concept of stateless computing facilitates much greater scalability and can be used in conjunction with virtualization to achieve maximum data center utilization.

One of the labs during the week showcased the Stateless Model in action , so what better way to help explain this feature then to walk through it again for all to understand?

When your service profile moves from one blade to the next, you will be booting the exact same SAN based OS. No configuration outside of UCS will ever be required at this time. The following overview is of the UCSM configurations performed in the lab. Select multiple UCS blades to be in a pool. Almost is if the hardware was like non persistent virtual desktops and UCSM was the user, Service Profiles will be able to move between the hardware in a pool allowing OS and application to run on any pool member without any further setup.

SAN ports and initiators are also to be grouped as pools. When server profiles move to another blade your FC fabric and storage see no change. No remapping will be required. For multipathing 2 triplets can be specified in the boot order.

Remember that the mezzanine cards do not provide multipathing, but the operating system is instead responsible. Create a MAC Pool for networking. Network interfaces are pooled as well.

This is matched to the configuration on the Northbound switches already created by the network administrator. Create Service Profiles to use Pools.

In the UCSM the service profile can be right-clicked where the administrator can choose to create a clone. 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.

Thus, hardware mobility is enabled through pools. Pooling servers that will be dedicated to similar functions, like ESX hosts for example, allows for workload mobility across reserved hardware.

Cisco called this hardware availability, and stressed this is not the same concept as high availability. If you recall from the previous posts that moving server workloads is a manual process that requires OS shutdown, then it makes sense that virtualization is needed for the true high availability scenarios.

In a non virtualization example, consider a database run on a UCS blade pool.
