Implementing Cisco UCS Solutions

Overview of this book

Cisco Unified Computing System(UCS) provides unique features for the contemporary data centres. Cisco UCS is a unified solution that consolidates computing, network and storage connectivity components along-with centralized management. Cisco UCS reduces TCO and improves scalability and flexibility. Stateless computing blade server's design simplifies the troubleshooting, and Cisco-patented extended memory technology provides higher virtualized servers consolidation results. A hands-on guide to take you through deployment in Cisco UCS. With real-world examples for configuring and deploying Cisco UCS components, this book will prepare you for the practical deployments of Cisco UCS data centre solutions. If you want to learn and enhance your hands-on skills with Cisco UCS solutions, this book is certainly for you. Starting with the description of Cisco UCS equipment options, this hands-on guide then introduces Cisco UCS Emulator which is an excellent resource to practically learn Cisco UCS components' deployment. You will also be introduced to all areas of UCS solutions with practical configuration examples. You will also discover the Cisco UCS Manager, which is the centralized management interface for Cisco UCS. Once you get to know UCS Manager, the book dives deeper into configuring LAN, SAN, identity pools, resource pools, and service profiles for the servers. The book also presents other administration topics including Backup, Restore, user's roles, and high availability cluster configuration. Finally, you will learn about virtualized networking, 3rd party integration tools and testing failure scenarios. You will learn everything you need to know for the rapidly growing Cisco UCS deployments in the real-world.

Learning to create a WWNN pool


WWNN is a 64-bit address assigned to Fiber Channel (FC) devices. In UCS, WWNN is assigned to the mezzanine card installed in a blade server because a mezzanine card can have more than one port (vHBA). Each port (vHBA) created from the mezzanine card acquires a unique World Wide Port Number (WWPN). (WWPN has been described in the next section.)

Following are the steps to create WWNN address pools:

  1. Log in to the UCSM screen.

  2. Click on the SAN tab in the navigation pane.

  3. Click on the Pools tab and expand root.

  4. Right-click on WWNN Pools and click on Create WWNN Pool as shown in the following screenshot:

  5. In the pop-up window, assign the Name and Description values to the WWNN pool.

  6. The selection of Default as the Assignment Order value is random. Select Sequential to assign the WWNNs sequentially.

  7. Click on Next as shown in the following screenshot:

  8. Click on Add in the next screen.

  9. In the pop-up window, change Size to create the desired number of WWNN addresses.

  10. Click on OK...
