Morgan Stepp CCIE #12603 | [email protected]Page 1 of 17 Configuring Cisco UCS C-Series for Unified Communications Overview The Unified Computing System (UCS) is Cisco’s server virtualization offering. In the early days of Cisco Voice, an MCS server was needed for each application. When combined with VMware, a single UCS server can power several UC applications. The UCS C-Series is common for small to medium deployments and comes in multiple configurations.

Install Vmware ESXi on UCS Cisco UCS C-Series Servers VMware Installation Guide http://www.cisco.com/en/US/docs/unified_computing/ucs/c/sw/os/vmware/install/VMWARE-esxi-install.html 1. Download ESXi customized Cisco UCS ISO VMware ESXI 5.1 U1 Installable Cisco Customized ISO Image https://my.vmware.com/group/vmware/details?downloadGroup=CISCO-ESXI-5.1.0U1-MAY2013&productId=285#product_downloads
2. Boot UCS from ESXi ISO: Web into CIMC, launch KVM, create virtual drive mapping to ISO
3. Install ESXi on the logical drive created above and reboot. Ensure you are installing on LUN 0 or server will not boot. During logical drive selection, press F1 to determine the LUN ID. This should be set to 0 as we saw in WebBios.
Press Enter to Reboot. After the ESXI installation, and server reboot, the ESXI server will take 2-3 minutes to boot. During this time, the server screen will display PXE boot and other boot notification messages.
5. Install VMware Vsphere Management Console. The default password is the same as above, unless you have edited this field (User: root Pass: none). Download and install the Vmware Vsphere Client by accessing the IP of your ESXi host from a browser or by using the links below.
Configure ESXi Networking Configure Networking to support EtherChannel. This can be done in trunk mode or in access mode as shown below. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004048 1. Configure Load Balancing on ESX Host: Select Configuration > Networking > Properties. Select the virtual switch in the Ports tab and click Edit. Click the NIC
Teaming tab. From the Load Balancing dropdown, choose Route based on ip hash. Ensure that standby adapters are moved up into “Active Adapters” section. Repeat these steps for “Management” network as it does not inherit settings.
2. After ESXi Load balancing is complete, configure EtherChannel on your Cisco Switch. interface Port-channel1 switchport access vlan 100 switchport mode access ! interface GigabitEthernet1/1 switchport access vlan 100 switchport mode access channel-group 1 mode on
3. After installing the ESXi host, you may experience slow TCP performance on VM’s. You can address this situation by disabling Large Receive Offload (LRO) on the ESXi host.
a. Log into the ESXi host or its vCenter with vSphere Client. b. Select the host > Configuration > Software:Advanced Settings. c. Select Net and scroll down slightly more than half way. d. Set the following parameters from 1 to 0.
1. Upload the UC ISO’s to ESXi Datastore. From within the vSphere Client, select your ESXi Host and the configuration tab. Right-click the Datastore you wish to use for storage of UC ISO’s, and select Browse Datastore. Later we will mount these to appear as local DVD source media.
From within the Datastore Browser, we can create folders and upload files. Below we have created an ISO folder and uploaded a few ISO’s.
2. Download OVA and create Virtual Machine. From within the vSphere Client, select File > Deploy OVF Template. You will be prompted to browse for the OVF or OVA file.
2. Launch and test UC Virtual Machine. You can now launch your Virtual Machine by right-clicking the Virtual Machine and selecting Power > Power On. Next, select Open Console to have KVM access to your server. From here we follow the normal setup steps required to deploy a UC Server.
Install VMware Tools VMware Tools are specialized drivers for virtual hardware accessed by virtual servers. It is important that the Tools version be in sync with ESXi. If VMware tools status does not show "OK" from the viClient, the VMware Tools should be upgraded. 1. Mount the VMware Tools ISO
a. Launch the VSphere Client and locate the Virtual Machine on which you wish to upgrade VMware Tools. b. Right-click the Virtual Machine and choose Guest > Install/Upgrade VMware Tools. Next, choose Interactive Tools Upgrade.
2. Initiate the VMware Tools Install a. Login to the Virtual Machine Console. Enter the CLI command utils vmtools upgrade.
b. The system reboots twice. Monitor the virtual machine console from the vSphere Client to see the system status. c. When the system is back up, the tools status is updated to OK from the vCenter Summary tab.
3. Remove the VMware Tools ISO
a. Select and Right-click the virtual machine which you are upgrading. b. Choose VM > Edit Settings > CD/DVD drive. Choose Device Type as Client Device.
Automate Virtual Machine Startup and Shutdown Virtual Machines can be configured to start and stop automatically when powering an ESXi Server host on and off. 1. Access the Virtual Machine Startup and Shutdown settings:
a. Select the UCS Host in vSphere. b. Select the Configuration tab. c. Select Virtual Machine Startup / Shutdown under Software. d. Click Properties in the upper right hand side of the window.
2. Configure the desired Startup and Shutdown options:
a. In order to configure options, enable Allow virtual machines to start and stop automatically with the system. b. Enter a value for the Default Startup Delay, in order to delay the startup activity for a period of time after the boot process
completes. c. Enter a value for the Default Startup Delay, in order to delay the startup activity for a period of time after the boot process
completes. Select which Shutdown Action you want to occur:
o Guest Shutdown: shut down the guest gracefully. This requires up to date VMware Tools to be installed in the guest. o Power off: abruptly stops power to the virtual machine, like pulling the power cord on a physical machine o Suspend: pause the virtual machine at that moment in time, like hibernating a physical machine
d. To start up the virtual machines in a particular order, configure the three Startup Order categories:
o Automatic: This category allows you to choose the sequence, by moving machines into this category, then arranging
them in order. o Any order: In this category, the machines are started in whatever sequence the host prefers (more or less
randomized). o Manual: In this category, the default, the machines are not automatically restarted. You must power them on
