-
*Span-based Silent Monitoring on UCS B-series chassis. For support on UCS C-series, please consult the VMware Community/Knowledge Base regarding the use of promiscuous mode to receive the monitored traffic from Span port; also consult the [http://www.cisco.com/en/US/products/sw/custcosw/ps14/prod_installation_guides_list.html CTI OS System Manager Guide for Cisco Unified ICM/Contact Center Enterprise and Hosted.]
 
-
*Cisco Unified CRM Connector.
 
-
*IPsec. UCS does not support IPsec off-board processing; therefore, IPsec is not supported in virtualization.

== Virtual Servers Deployment Model ==
 
-
 
-
Release 10.0(1) supports only virtual deployments.

-
 
-
The following additional software requirements apply specifically to Unified Contact Center Enterprise:
 
-
 
-
:*If you are upgrading ESXi software, see [http://docwiki.cisco.com/wiki/Ongoing_Virtualization_Operations_and_Maintenance Upgrade ESXi] and the [http://www.cisco.com/en/US/products/sw/custcosw/ps1844/prod_installation_guides_list.html Cisco Unified Contact Center Enterprise Installation and Upgrade Guide.]
 
-
:*For more information about Microsoft Windows Server, Microsoft SQL Server, and other third-party software requirements for virtualized Unified CCE applications, see the [http://docwiki.cisco.com/wiki/Compatibility_Matrix_for_Unified_CCE Compatibility Matrix for UCCE.]The Windows, SQL, and other third-party software requirements for the Unified CCE applications in the ESXi/UCS platform are the same as in the physical server.
 
-
 
-
=== ESXi 5.0 and 5.1 Software Requirements  ===
 
-
 
-
When Cisco Unified CCE is running on ESXi 5.0 and 5.1, you must install or upgrade VMware Tools for ESXi to match the running version on each of the VMs and use all of the VMware Tools default settings. You must do this every time the ESXi version is upgraded. For more information, see [http://docwiki-dev.cisco.com/wiki/Alpha_1_Temporary_Virtualization_for_Unified_CCE_Release_10#Installing_VMware_Tools Installing VMware Tools.] 
 
-
 
-
Disabling the LRO in ESXi 5.0 (and later) is no longer a requirement.

-
= Unified CCE Component Capacities and VM Configuration Requirements  =
 
-
 
-
For supported Unified CCE&nbsp;component capacities and VM computing resource requirements, see the [http://docwiki.cisco.com/wiki/Unified_Communications_Virtualization_Downloads_%28including_OVA/OVF_Templates%29#Unified_Contact_Center_Enterprise List of Unified CCE OVA Templates.]

-
 
-
Note that the implementation of specific features reduces the scalability of certain components below the capacity (of the respective OVA) that is stated in  [http://docwiki.cisco.com/wiki/Unified_Communications_Virtualization_Downloads_%28including_OVA/OVF_Templates%29#Unified Unified Communications Virtualization Downloads (including OVA/OVF Templates).] For more details, see the [http://www.cisco.com/en/US/products/sw/custcosw/ps1844/products_implementation_design_guides_list.html Unified Contact Center Enterprise Design Guide.]  <br>

-
 
-
For any single Direct Attached Storage (DAS) array, you cannot have two or more of the following on any single array: Logger, Rogger, HDS, or CVP Reporting Server.
 
-
 
-
For more information about sample Unified CCE deployments, refer to the [http://tools.cisco.com/ucs Collaboration Virtual Machine Placement Tool.] This tool is currently in beta and does not enforce co-residency. As mentioned above, refer to the Unified CCE Component Coresidency and Sample Deployments page for more information.

-
 
-
 
-
 
-
== Creating Virtual Machines by Deploying the OVA Templates  ==
 
-
 
-
In the vSphere client, perform the following steps to deploy the virtual machines:
 
-
 
-
#Highlight the host or cluster to which you want the VM to be deployed.
 
-
#Select '''File''' &gt; '''Deploy OVF Template'''.
 
-
#Click '''Deploy from File''' and specify the name and location of the file you downloaded in the previous section '''OR '''click '''Deploy from URL''' and specify the complete URL in the field, then click '''Next'''.
 
-
#Verify the details of the template, and click '''Next'''.
 
-
#Give the VM you are about to create a name, and choose an inventory location on your host, then click '''Next'''.
 
-
#Choose the datastore on which you would like the VM to reside. Be sure that there is sufficient free space to accommodate the new VM, then click '''Next'''.
 
-
#Choose a virtual network for the VM, then click '''Next'''.
 
-
#Verify the deployment settings, then click '''Finish'''.
 
-
 
-
== Notes  ==
 
-
 
-
:*VM CPU affinity is not supported. You may not set CPU affinity for Unified CCE application VMs on vSphere.
 
-
:*VM Resource Reservation is set appropriately when the VM is deployed from the OVA for CCE 10.0.
 
-
:*You must not change the computing resource configuration of your VM at any time, unless explicitly directed to do so when performing a common-ground virtual upgrade. Computing resource reservation requirements can change from one Unified CCE version to another, and manual adjustments will be necessary during the upgrade process.
 
-
:*ESXi Server hyperthreading is enabled by default.
 
-
:*VM vDisks must be deployed as either Thick Eager-Zeroed or Thick Lazy-Zeroed; thin provisioning of Unified CCE VM vDisks is '''not''' supported. Use Eager-Zeroed for best performance of application VMs on initial writes. For more information, see [http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware UC Virtualization Supported Hardware.]
 
-
 
-
<br>
 
-
 
-
== Preparing for Windows Installation  ==
 
-
 
-
In the vSphere client, perform the following steps to prepare for operating system installation.
 
-
 
-
#Right-click on the virtual machine you want to edit, and select '''Edit Settings'''. A '''Virtual Machine Properties''' dialog appears.
 
-
#On the '''Hardware''' tab, select '''CD/DVD Drive 1'''. Under Device Type, select '''Datastore ISO File''',  and enter the location of the operating system ISO.
 
-
#Click '''OK''' to save setting changes.
 
-
#Power up your VM and continue with operating system installation.

= Remote Control of the Virtual Machines  =
 
-
 
-
For administrative tasks, you can use either Windows Remote Desktop or the VMware Infrastructure Client for remote control. The contact center supervisor can access the ClientAW VM using Windows Remote Desktop.
 
-
 
-
You can also use the Cisco Integrated Management Controller (CIMC) to manage and monitor C-Series Rack servers and the Cisco Unified Computing System (UCS) Manager to manage resources for virtual machines. For more information, see [http://www.cisco.com/en/US/products/ps10493/products_configuration_example09186a0080b10d66.shtml Set up CIMC for UCS C-Series Server] and [http://www.cisco.com/en/US/products/ps10281 Cisco UCS Manager.]

-
<br>
 
-
 
-
= Installing VMware Tools  =
 
-
 
-
The VMware Tools must be installed on each of the VMs and all of the VMware Tools default settings must be used. Please refer to VMware documentation for instructions on installing or upgrading VMware Tools on the VM with the Windows operating system.
 
-
 
-
<br>
 
-
 
-
= Timekeeping Best Practices for Windows  =
 
-
 
-
Follow the instructions provided in the VMware Knowledge Base article [http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1318 VMware KB: Timekeeping best practices for Windows].
 
-
 
-
*ESXi hosts and domain controllers must synchronize the time from the same NTP source.
 
-
*When Unified CCE virtual machines join the domain, they synchronize the time with the domain controller automatically using w32time.
 
-
*Be sure that '''Time synchronization between the virtual machine and the host operating system''' in the VMware Tools tool box GUI of the Windows Server 2008 R2 guest operating system remains deselected; this check box is deselected by default.

= System Performance Monitoring Using ESXi Counters  =
 
-
 
-
:*Make sure that you&nbsp;follow VMware's ESXi requirements and the SAN vendor's instructions for optimal system performance.&nbsp;
 
-
:*VMware provides a set of system monitoring tools for the ESXi platform and the VMs. These tools are accessible through the VMware Infrastructure Client or through VirtualCenter.
 
-
:*You can use Windows Performance Monitor to monitor the performance of the VMs. Be aware that the CPU counters may not reflect the physical CPU usage since the Windows Operating System has no direct access to the physical CPU.
 
-
:*You can use&nbsp;Unified CCE Serviceability Tools and&nbsp;Unified CCE reports to monitor the operation and performance of the&nbsp;Unified CCE system.
 
-
:*The ESXi Server and the virtual machines must operate within the limit of the following ESXi performance counters.
 
-
 
-
<br>
 
-
 
-
Use the following ESXi counters as performance indicators.
