This document covers the Procedure for Dumping CUCM Fresh Install Logs - Virtualization Problem Description In order to dump install logs on a virtual UC installation, it is necessary to use a virtual serial port on the virtual machine. Also always ensure a DRS backup of the Cisco Collaboration applications is available in case there are issues with the replicated VMs. The Cisco DocWiki platform was retired on January 25, 2019. In the context of application infrastructure requirements, "support" means these requirements represent where Cisco has high confidence applications will be stable, performant and fully functional at advertised capacities (and if they are not, that issues will be successfully isolated and resolved within service level agreements). VMware.com comparison of vSphere editions (available on this web page at time of this writing: General-purpose licenses may be customer-provided instead of purchased from Cisco. Certain other virtualization features may mandate vCenter based on VMwares license editions. Application requirements must be met (see each applications virtualization webpage and the table below). See the documentation for the UC application software or UC appliance software to see what is supported. VMware vSphere 5.0+ only offers the ESXi architecture option. VM placement and derivation of required hardware specs. Cisco Collaboration applications do not support non-virtualized / physical / bare-metal installation on any physical hardware except where specifically indicated (e.g. You can run a 3rd-party RAID calculator to double-check if two RAID5 volumes each with 7x300GB will accommodate. Required VM count for software redundancy will fit on pair of blade servers.
For "complex" issues isolated to VMware/hardware layers, without vCenter historical data, root cause analysis may not be possible. vSphere Storage Appliance (VSA)
Software upgrades of the UC application will preserve the version of VMware Tools currently running. VMsafe
Minimum required memory is ~114GB, but well align with BE7000H (M5) and spec 192GB. BE6000M (M5) appliance uses Intel Xeon 4114 CPU (10C/2.2GHz), so select that (all applications' small capacity point will support Xeon with base frequency 2.20 GHz). VMware Fault Tolerance
5.0 U3 on UCS C220 M3 SFF, check the UCS interop matrix to see if any updates required before U3 will work on that hardware. 5.1 U1) if required by its guest OS or for hardware compatibility. Virtual Appliance Packaging of UC apps
Any on-premises hybrid extensions of 3rd-party public cloud infrastructure (e.g. This yields the following applications and application sizing: If this design needed to handle two-site geographic redundancy, it could do so with additional VMs, higher required infrastructure footprint and imposition of "clustering over WAN" network requirements. must show as supported on the VMware Compatibility Guide for the UCM ESXi version. E.g. The vmv represents the version of virtual hardware. VMware Tools
CUCM Class of Service. Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client.
File Deploy OVF Template, eg: \OVA-ISO\cucm_10.5_vmv8_v1.8.ova; Right click virtual machine, EDIT virtual machine settings, and insert a Boot CD!
To remove the VMware Tools tar file, perform the following substeps. To migrate from bare-metal servers (e.g.
Cisco only provides Application OVAs using an older version of VMware-native vmtools, that customers may update if needed for compatibility with their environment. C220 M5SX chassis will be used for up to 10 hard disk slots, which allows lower-cost HDD to be used (vs. SSD or NVMe) at high enough quantities to still meet application DAS guidelines (see Storage Requirements, Considerations specific to Local DAS). Other features from vSphere Standard Edition. Specifically for Cisco Unified Attendant Consoles, this means the CUxAC VM must not be doing any Hot Swap or taking any active calls, with no active Directory Synchronization in progress. The following applies to any use of vMotion with UC apps: UCM, IMP and CUC have caveated support (see
Cisco Collaboration Infrastructure Requirements Introduction General This page summarizes Hardware requirements and Virtualization Software requirements for Cisco Collaboration applications. Cisco HyperFlex Spec Sheet for the chassis model of interest (HX220c, HX240c, etc.). UCM cluster nodes require fixed capacity points with fixed-configuration VMs in the Cisco-provided OVA for UCM.
Plan for dual RAID5 volumes. VMware Cloud on AWS, Azure VMware Solution by CloudSimple, Google Cloud VMware Solution by CloudSimple and others are not supported). Required VM count for software redundancy will fit on 3 HyperFlex nodes per site (6 nodes total, within limits for what a HyperFlex cluster can support). VMware Hot Add
Here are some example questions: Will Cisco support this?
Like the BE7000H (M5), we will also spec dual quad-port 1GbE NICs to provide extra links and accommodate typical needs for NIC teaming and/or VLAN trunking. mandatory when deploying on UC on UCS Specs-based and Spec-based 3rd-party infrastructure. New ESXi versions may increase the latest vmv version, but new ESXi versions support older vmv versions (see vmware.com for information on compability of old vmv versions with new ESXi versions, such as this vmware.com KB article for compatibility for ESXi version with vmv version). See the Install and Upgrade guide for Cisco Unified Intelligence Center 11.0 and later for more details.) Each HyperFlex node will require a HyperFlex Data Platform (HXDP) storage controller VM of 8vcpu, in addition to the application VMs. ESXi 6.7 U2, vmfs6, vmv15, vmtools 10.3.10). All apps and ESXi will boot from this volume. The only supported scenario is a manual move to a different server, e.g. VMware Consolidated Backup (VCB)
Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. Cisco does not produce OVA files for newer vmv versions, or test newer vmv versions since VMware indicates these are backwards compatible. 2 or 3
If VMware tools status does not show "OK" from the viClient, the VMware Tools must be upgraded. License Comparison - Install Base
Under the Advanced section, check the Check and upgrade Tools during power cycling option. Was only sold as 5.x. It is important to understand that the UC application is not tied to the version of ESXi it is running on. Cisco physical / virtual networking infrastructure is presumed transparent to Collaboration workloads. Disable LRO if on ESX 4.1 and app version < 8.6. vCenter Statistics Level 4 logging is mandatory so that Cisco TAC is able to provide effective support. Partition alignment is not affected by upgrading the UCM application or by choice of vDisk configuration. See vMotion for what is supported. Cisco 7800 Series Media Convergence Server) to UC on UCS, the supported procedure is:
P2V tools are not supported. Cisco Collaboration apps do not prescribe or proscribe individual ESXi patches and updates. mandatory when deploying on Tested Reference Configurations of Cisco HyperFlex (because HyperFlex management requires vCenter). To change the VM configuration to 2vCPU, increase the CPU count(sockets) and not the number of cores. VMware vShield
For most Collaboration deployments, RAID5 has been the best tradeoff among competing factors of maximizing usable space, IO performance, fault tolerance, and ease of failed disk replacement while minimizing total storage system price and complexity. Collaboration apps are mission-critical, resource-intensive and latency-sensitive. Not supported. E.g. May only be done during a maintenance window with UC VMs shut down. Hardware components, models and product IDs may have changed since the time of this writing. Step 4 When the system is back up, the tools status is updated to OK from the vCenter Summary tab for the virtual machine that you upgraded. VMware Data Recovery
See vMotion for what is supported.Long Distance vMotion is a joint Cisco and VMware validated architecture for using the vMotion feature across data centers. Note: The 2,500 user VM configuration with one vCPU may exhibit performance issues during CPU/IO-intensive operations (such as installs, upgrades, backups and CDR writes, significant usage of CTI), or if your deployment has certain characteristics such as a large quantity of TFTP files. Step 2 Choose the automatic tools update and press OK. The only supported scenario is a manual move to a different server, e.g.
You can run a 3rd-party RAID calculator to double-check if 6x300GB in a single RAID5 will accommodate. For older ESXi releases, the VMFS is transparent to Cisco Collaboration apps, but recommend using the latest version offered for the major/minor version of VMware vSphere ESXi you are deploying on. HCL, latencies, application VM capacity and performance needs). Cisco supports only VMWare ESXi virtualisation which makes sense!
1, 2 or 3
Note that Cisco Unified Communications applications upgrades, patches and updates can not be delivered through VMware Update Manager. This is because during the vMotion cutover, the system is paused, which for real-time UC apps creates service interruption which degrade voice quality after the migration for calls in progress. 1, 2 or 3
If the UC app is listed as "Partial" support, then support is "maintenance mode only" as described below:
larger VMs, more virtual HW options, etc.). Minimum required memory is ~50GB. Customers who wish to add additional vcpu and/or additional vram beyond this minimum to improve performance may do so, but note the following: IOPS and Storage System Performance Requirements. Not supported. Installed base version upgrades until end of support.
This will occur automatically. Otherwise, unless indicated NOT to by a Cisco Collaboration app, customers are free to manually upgrade the vmv to a newer vmv supported by the ESXi version. Prior to copying, the VM must first be shutdown (which will shut down the virtual server, the UC OS and the UC application). Cisco physical / virtual networking infrastructure is presumed transparent to Collaboration workloads.
Required VM count for software redundancy will fit on pair of rack servers. Also always ensure a DRS backup of the Cisco Collaboration applications is available in case there are issues with the replicated VMs. click to download OVA file, Supported Hardware (Latest)
See documentation of those applications for details. See vMotion for what is supported.Long Distance vMotion is a joint Cisco and VMware validated architecture for using the vMotion feature across data centers. To configure a trunk, proceed to Connectivity -> Trunks. Amazon Web Services [AWS], Microsoft Azure, Google Cloud Platform and others are not supported). VMware Snapshots
Any on-premises hybrid extensions of 3rd-party public cloud infrastructure (e.g. NOTE: support varies by app and version.
This is because during the vMotion cutover, the system is paused, which for real-time UC apps creates service interruption which degrade voice quality after the migration for calls in progress. Another alternative is manual Virtual Machine shutdown and migration. Upgrades from 8.x VMs with 2x80 GB vDisk to 9.1 or higher are not required to change the vDisk. All apps and ESXi will boot from this volume. Assume campus network already exists (Catalyst and ISR based, with PSTN, WAN and Internet connections) and passes VOIP readiness assessment. Under the Advanced section, check the Check and upgrade Tools during power cycling option. Minimum required memory is 30GB. vSphere Data Protection (VDP)
HQ site has high-profile users who require WAN survivability. If the UC app is listed as "Supported with Caveats", then support is as described below:
The Cisco VoIP/CCME section aims to provide a solid VOIP configuration reference guide to the VoIP community. Not supported. The following applies to any use of vMotion with UC apps:
This feature automatically restarts a Virtual Machine (VM) on the same physical server or a different physical server. NOTE: support varies by app and version. So we will align with BE7000H (M5) and instead spec 192 GB. NOTE: support varies by app and version. This page has been updated to reflect compatibility with the latest M5 hardware. IOPS and Storage System Performance Requirements. In fact you can use the simplest virtualization tool from the whole VMware outfit and nowadays you can install CUCM even on VMware Player. Advanced features not included (HA, vMotion, DRS, etc.). See the documentation for the UC application software or UC appliance software to see what is supported. If the UC app is listed as "Partial" support, then support is "maintenance mode only" as described below:
Not supported for other applications. All hardware/software for collaboration must be redundant. Not supported. vCPU/vRAM increases alone do not increase supported capacity, max density per cluster node or max scale per cluster. via Distributed Resource Scheduler [DRS]), a few applications have caveated support (see here for details); otherwise it is not supported. Logical Cores do not increase the number of physical cores available to apps. LoM: 2x10GE Cu LoM LAN + 1x1GE CIMC (RJ45).
