Cisco UCS potentially changed my mind about the GUI!

The past two weeks of work have been pretty busy; filled with Nexus labs, everyday miscellaneous tasks, and now learning Cisco UCS. Basically, at least the way I understand it, the Unified Computing System is Cisco’s way of bringing your network, storage, and servers of your data center together. I might add that it does an awesome job at that too!

In our rack we have two 6248UPs that connect down to the UCS blade server via FCOE (4 10Gb links to each 6248UP for a total of 8 links). We then have the 6248UP connecting up to the Nexus 7010 via fiber Ethernet (4 10GB links, 2 from each 6248UP). Lastly, we have 4 FC links going from each 6248UP to our MDS SAN. Pheww!! you do not want me to tell you how long it took me to wrap my head around all this lol. The 6248UP is an awesome switch that can speak ethernet, fiber channel, and fiber channel over ethernet which makes it very useful in data center environments. Oh and one more thing, the 6248UPs are also connected to each other through their L1 and L2 ports. These ports need to be connected in order to have the two 6248s run in cluster mode. Also management ports were connected. Okay that’s it I’m done lol. I am posting a picture below of the basic topology of what I described above. The only difference is that our equipment and links are slightly better then what the topology shows.

So yesterday I decided to go ahead and start on the initial configurations of getting this all connected. First I cabled everything up as described above. Next I consoled into the 6248UPs and configured them in cluster mode. The whole setup is very intuitive. All I had to do was enter some basic IP address information on each of the switches and say that I want to run them in cluster mode. I also had to enter a Virtual IP that the switches would share. After all that was done I could then open up my web browser and browse to the virtual IP address. This took me to the UCS manager interface. All I can say is this interface is awesome! it gives you information on the entire UCS system on just about anything you would ever want to know. You can also configure the ports by right clicking them. The only configuration I did was changed the 8 links we have going down to the UCS to server ports. Hopefully today I will have time to go back in and play around a little more. Oh and I forgot to mention the UCS manager even builds you a graphical network topology of what it detects connected to it! :)
