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.

Configuration Detail Configure UCS CIMC 1. Attach Local Keyboard / Monitor and Power on UCS. At Cisco splash screen, Press F8 to launch CIMC Config
2. Configure CIMC Network Information (No User / Pass). The Shared LAN On Motherboard (LOM) with Active-Active
redundancy allows both UCS NIC’s to connect into your Network Infrastructure and participate in options like
EtherChannel. We have enabled VLAN Tagging to place all CIMC frames into VLAN 10. If there are Virtual Servers
residing in different VLAN’s, enable this along with a trunk config on the switch. If all Virtual Servers are in the same
VLAN, tagging is not required. The settings for NIC mode “Dedicated” and Redundancy “None” allows EtherChannel for
vmware (mgmt and vmachines) across LOM and PCI card for card level redundancy (set via vSphere later on).
3. Web into IP above for CIMC Management Console (User: admin Pass: password)

Configure UCS RAID
1. Configure UCS Raid with WebBios. At the Drives Screen, press Ctrl+H to enter WebBios. Create Virtual
Drives and set Boot Order.
2. Create Virtual Drives and set Boot Drive. In 10 HDD system (ex c210-M2), it is recommended to have [2]
drives->raid1 for ESXi and [8] drives->raid5 for VM’s. This is the default configuration on C210M2-VCD2, but
always verify.
Raid 10 Configuration (recommended) – will use 4 physical drives to create 1 mirror set with striping,
resulting in a 1.8TB Virtual Drive. For business critical data, RAID 1+0 (or Raid 10) gives the best combination
of performance, availability and redundancy.
Morgan Stepp CCIE #12603 | [email protected] Page 6 of 17
Raid 1 Configuration (optional) – will use 4 physical drives to create 2 mirror sets, each 931GB in size

Configure UCS Boot Order
1. At the CIMC splash screen, Press F2 to enter BIOS. Under “Boot Options” tab, select the “PCI Raid Adapter” first.
2. Under the Advanced tab, go to Mass Storage Controller Configuration > SATA Mode to enable SW RAID. When done,
press F10 to save and reset.

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.
Morgan Stepp CCIE #12603 | [email protected] Page 13 of 17
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.
Net.Vmxnet2HwLRO Net.Vmxnet2SwLRO Net.Vmxnet3SwLRO Net.Vmxnet3HwLRO Net.VmxnetSwLROSL
Reboot the ESXi host to activate these changes.
Deploy Virtual Machines
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.
Morgan Stepp CCIE #12603 | [email protected] Page 14 of 17
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.

Once the Virtual Machine is created, right-click and select “Edit Settings”. Map the CD/DVD Drive to the ISO you uploaded
earlier. Ensure you select the “Connect at power on” option. The server will now boot from this ISO.
In some cases, the VMware BIOS is not set to boot from DVD. You may need to go under the options tab below and
select Boot Options. Check the “Force BIOS Setup” checkbox. After powering on server, change the BIOS boot order to
select the DVD first.

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
manually.
