The Cisco Unified Communications IM&P server uses the same virtualization approach that is used by CUCM or Cisco Unity Connection. Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. Latency values over time are expected to fluctuate. Later, a CLI command was created to make the upgrades easier. If VSA is desired to be used as shared storage for a virtualized Cisco Collaboration deployment, it must meet the storage requirements for UC on UCS Specs-based or 3rd-party Server Specs-based (e.g. This feature provides integration with 3rd-party backup utilities so that they can non-disruptively backup the OS and application in a Virtual Machine (VM). Assume Xeon 6132 which will support required applications' "medium" capacity point and VM configurations. 1 active Collaboration Flex subscription or Software Support Service contract on perpetual licenses that include UCM). Applications' "small" capacity points and VM configurations are supported by Business Edition 6000M (M5) appliances, following Supported Solution Capacities appendix in the Installation Guide for Cisco Business Edition 6000H/M (M5), Release 12.5. 7.x of UC apps with VMware vSphere on limited 3rd-party servers), see the following links: Cisco requirements are to prevent these types of issues from impacting application availability to end-users. Virtualization Jungle . Redundant power supplies are recommended. Customers can use these multiple NICs for VM network traffic, VMware console access, or management "back-doors" for administrative access, backups, software updates or other traffic that is desired to be segregated from the VM network traffic. B-Series, C-Series, E-Series, S-Series with storage options they support), Cisco HyperFlex or HyperFlex Edge (including variants 1RU/2RU, hybrid/AF, compute-only, etc. b. Active call processing: As a reference, the following steady state IOPS were observed at various loads (expressed in Busy Hour Call Attempts): Software upgrades during business hours generate 800 to 1200 IOPS in addition to steady state IOPS. C220 M5 SFF, C240 M5 SFF, HX220c M5, B200 M5, etc.). Cisco TAC will isolate Collaboration app issues to the app or infrastructure. NOTE: support varies by app and version. For "complex" issues isolated to VMware/hardware layers, without vCenter historical data, root cause analysis may not be possible. 7.x of UC apps with VMware vSphere on limited 3rd-party servers), see the following links: The vmv represents the version of virtual hardware. Existing UC app methods of backing up the software continue to be supported. VMware vCenter Converter Any 3rd-party public cloud offers that dont use VMware technology (e.g. Caveated Support for VMware CPU Reservations and Distributed Resource Scheduler). Fast manual server moves, e.g. (Usually, the VMware Tools tar file is called linux.iso). Cisco Unified Communications IM&P consists of up to six servers, including one server that is designated as a publisher. Configuring CUCM - Virtual Machine deployment 4,566 views Aug 18, 2015 26 Dislike Share Go CodeGuru 1.05K subscribers Welcome to the Cisco Unified Call Manager Series. a. Right-click the virtual machine that you are upgrading, and choose Guest > Install/Upgrade VMware Tools. See vMotion for what is supported. See vMotion for what is supported. Cisco UCS servers use "soft media" such as ISO or FLP (virtual floppy) for procedures that require external media (such as installation and upgrade). In QuoteCollab tool, model VM placement and note tallied hardware requirements for each hardware node. . See Resize Virtual Machine instead. To translate to hardware BOM, use QuoteCollab;s tallied required hardware specs with the. E.g. Updates are performed automatically. VMware Data Recovery Not supported. This is a minimal VM configuration for use with Cisco Hosted Collaboration Solution. NOTE: support varies by app and version. Log into the ESXi host or its vCenter with vSphere Client. See vMotion for what is supported. E.g. USA-based, so requires compliance with US FCC Kari's Law / Ray Baum's Act. Example uses VIC 1440 mLOM. "Rogger"). The 1,000 user VM configurations generates about 60 IOPS during steady-state. Requirements on this page only apply to these software release combinations: Choose Device Type as Client Device. To date, Cisco has not discovered any issues with Collaboration apps due to a newer vmv version. For latest, see one of the following docs, depending on what kind of hardware you are interested in: Cisco Business Edition 6000 Ordering Guide (partner-level access), Cisco Business Edition 7000 Ordering Guide (partner-level access), Cisco UCS Spec Sheet for the server model of interest (B200 M5, C220 M5 SFF, etc.). 3 If purchased from and supported by Cisco (e.g. License Comparison - Install Base HyperFlex Edge is permitted, but only with 10GE deployment models. Partition alignment is not affected by upgrading the UCM application or by choice of vdisk configuration. Not supported. To remove the VMware Tools tar file, perform the following substeps. Follow Business Edition 6000 ordering guide for quoting instructions (toplevel product ID BE6M-M5-K9). If later we find we need more links, faster links or different interconnect type, we can always add additional NICs or Cisco VICs later. Cisco recommendation is to use the latest Maintenance release supported by the hardware vendor. Not supported. This content has been moved to Cisco Collaboration Infrastructure Requirements: Cisco Collaboration apps will explicitly indicate which Major/Minor versions they support (e.g. VMware High Availability (HA) Step 5 After installation of the new version of VMware Tools is complete, remove the VMware Tools tar file from the virtual CD/DVD drive. VMware Tools are specialized drivers for virtual hardware that is installed in the UC applications when they are running virtualized. upgrade to 8.x software version on the bare-metal server Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. Required VM count for software redundancy will fit on pair of BE6000M (M5) appliances. Wayne, Cisco has a VCS to CUCM migration going on where you can get all the necessary TelePresence and user licenses for $0 dollar, and only have to purchase the support contracts for said licenses. a. Right-click the virtual machine that you are upgrading, and choose VM > Edit Settings > CD/DVD drive. General-purpose licenses can be either purchased from and supported by Cisco, or purchased from and supported by a 3rd-party (VMware or other vendor). Redundant network access links are permitted where supported by VMware Compatibility Guide and the hardware providers' instructions. VMsafe See vMotion for what is supported. 5.1 U1) if required by its guest OS or for hardware compatibility. The "storage system" is defined as all hardware and software end-to-end required for the UCM virtual machine's vdisk to be available to the application. 100% work from home + mobile roaming support. Performance is dependent on many factors including deployment specifics, so vCPU/vRAM increases may or may not improve performance. Applications' "large" capacity points ("medium" for Expressway) and VM configurations are supported by Business Edition 7000H (M5) appliances. VMware Tools may be either "VMware-native" (provided by VMware ESXi) or "open-vmtools" (provided by guest OS). NOTE: support varies by app and version. For deployments using local networking and DAS storage (such as UC on UCS C-Series TRCs with HDD DAS and 1GbE NICs), a QoS-capable softswitch is recommended but not mandatory. However, using this feature to patch and update the guest OS is only supported by some applications and some versions, this is what is shown on this page when referring to VUM support. Migration of UC VMs that are live and processing live traffic is supported, but note that Cisco testing cannot cover every possible operational scenario. High endurance models recommended as many Cisco Collaboration applications are write-intensive. If you are migrating from a physical server with more than 80 GB of storage space to a virtual machine with a user deployment size of either 500 or 2,000, see the Disaster Recovery System Administration Guide for more information. New installs of 9.1 and above must use 1x110 GB vDisk. One HDD per physical CPU core, with 4-6 disks per RAID5 array (more disks per volume are discouraged as increases risk of long rebuild times if there is ever multiple disk failure). Introduction to Cisco Unified Communication Manager. NOTE: support varies by app and version. Basic understanding of CUCM , IM&P & Cisco unity connection version (N-1). The only supported scenario is a manual move to a different server, e.g. VMware Boot from SAN There is no need to manage compatibility / updates of open-vmtools. 2 Adding vNIC is not supported unless the UC app supports multiple network connections with different IP addresses. Values consistently greater than 20-30ms are frequently performance problems for typical applications. Which method to use: Early versions of the Collaboration applications required a COP file in order to upgrade the VMware Tools. Was only sold as 5.x. Click here for VMware's direction to transition from ESX to ESXi. Note: Feature support for Cisco Unified Contact Center Enterprise varies by component (e.g. If the UC app is listed as "Supported with Caveats", then support is as described below: Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. E.g. Cisco Collaboration Virtualization Click on an application name to view its virtualization support. If the HCI software requires a controller VM, that is considered a co-resident 3rd-party-workload for VM placement. Step 2 To mount the correct version of the VMware Tools software in the Guest virtual CD/DVD drive, perform the following sub-steps. UCM cluster nodes require fixed capacity points with fixed-configuration VMs in the Cisco-provided OVA for UCM. VMware Fault Tolerance VMware Fault Tolerance NOTE: support varies by app and version. VSA is not really a "feature" but rather a storage product from VMware. We also have a written guide which. Please note the following caveats: Logical Cores do not increase the number of physical cores available to apps. Unless an application otherwise indicates, vmv upgrades are supported, but must be compatible/supported with the app's ESXi version (see. Application Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. If you use vCenter, then unless otherwise indicated, Cisco applications do not require their own dedicated vCenter. Plan to have 2+ hardware nodes for redundancy. Assume campus network already exists (Catalyst and ISR based, with PSTN, WAN and Internet connections) and passes VOIP readiness assessment. This example will use a minimum build of 3x SAS 1.2 TB. VMware Update Manager (VUM) VMware Site Recovery Manager (SRM) VMware Boot from SAN VMware vShield 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. For real-time load-balancing of live UC VMs (e.g. 1R/2RU, hybrid storage vs. all-flash are all permitted. Before applying a VMware upgrade or update to a host, always verify compatibility with each Cisco Collaboration app (At a Glance table at, Note that use of VMware vSphere ESXi 4.1 requires disabling the "LRO" setting (. See VMware High Availability for what is supported. Not supported. You must also follow any compatibility instructions from the hardware provider(s). then Cisco will provide support for ESXi. Used to preserve the state of a VM without copying or creating additional VMs, effectively as a backup/restore or reversion technique. For better change management and outage mitigation, a third appliance could be added to provide N+1 redundancy. Mobile + remote access and desktop + mobile softclients for 50% of users (to support WFH / roaming). Like the BE7000M (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. take a software backup Not supported. It is the sum of two other latency values (GAVG = KAVG + DAVG): "KAVG/cmd" (VM Kernel Average Latency per command) - an indicator of CPU resources/performance. Not supported for other applications. VMware Snapshots 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. Installing a Cisco Unified Communications Manager (CUCM) Server, Version 12.0Get Kevin's FREE Collaboration Mini-Coursehttp://kwtrain.com/6coresys=====. Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. By default, a serial port is not present when deploying from the Cisco provided OVA. With a particular supported major/minor version (such as ESXi 5.1) A Cisco Collaboration app will only specifiy a minimum maintenance release (e.g. When deployed on a BE6000S server, minimum supported version is 10.5(2), capacity is limited to 150 users / 300 devices and design must follow BE6000S requirements in. Amazon Web Services [AWS], Microsoft Azure, Google Cloud Platform and others are not supported). If the server is Cisco UCS, you may need to use a UCS-specific image for U3 on vmware.com. Destination physical server must not end up with over-subscribed hardware after the migration. Minimum required memory is ~122GB. 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. Server Vendor's hardware compatiblity information for the vSphere ESXi Major/Minor version required by Cisco Collaboration. Applications are sized with redundant VMs. Enabling CAR continuous loading results in around 300 IOPS average on the system. This feature provides an automated disaster recovery solution that works on a "site to site" basis, where a "site" comprises physical servers, VMware and SAN storage. Follow HX DIMM population rules for 8x16GB=128GB. Requirements on this page only apply to these software release combinations: Some applications may have application-specific rules that are different. See the Install and Upgrade guide for Cisco Unified Intelligence Center 11.0 and later for more details.) 2 or 3 When deployment on a BE6000S server and version is 11.0 or higher, capacity is limited to 150 users/ 300 devices and design must follow BE6000S requirements in, vCPU/vRAM increases alone do not increase supported capacity, max density per cluster node or max scale per cluster. Not supported. VMware vCenter Converter The only supported scenario is a manual move to a different server, e.g. Moving a shut down VM during a maintenance window, i.e. The Cisco VoIP/CCME section aims to provide a solid VOIP configuration reference guide to the VoIP community. This feature provides an automated disaster recovery solution that works on a "site to site" basis, where a "site" comprises physical servers, VMware and SAN storage. Ephemeral spikes above application's indicated maximum with tiny duration and tiny frequency are expected, but spikes above the application's indicated maximum that are frequent, sustained and/or high-magnitude indicate a potential problem and are likely contributors to application symptoms. Not supported. However, if Storage vMotion must be used, it is only under the following conditions: Plan for a C240 M5 rack-mount server that emulates the specs of Business Edition 7000H (M5) appliance. Assume Xeon 6126 which will support required applications' "medium" capacity point and VM configurations. Cisco recommends to power off the VMs before the SAN replication occurs. This feature provides an automated disaster recovery solution that works on a "site to site" basis, where a "site" comprises physical servers, VMware and SAN storage. Cisco Unity Virtualization Design Guide If HyperFlex or 3rd-party shared storage (HCI, FCoE/iSCSI/NFS-attached), remember the same network links carry VM vnic and vdisk traffic, so factor both traffic types into capacity and QoS planning. Unified CCX It can be used to supplement software redundancy as a means of fast, automated Failed-server recovery when a VM (but not the application) is hung or if there is a fault with the physical host server or VMware software. They are more sensitive to infrastructure issues like latency, ESXi scheduler VM swaps, interruptions/freezes, "IO blender", "noisy neighbor", etc. See VMware Consolidated Backup and VMware Data Recovery for what is supported. A Cisco Collaboration app will only specifiy a minimum maintenance release (e.g. E.g. You can run a 3rd-party RAID calculator to double-check if 6x300GB in a single RAID5 will accommodate. For example, initial deployment of the OVA and UC application may have been done on ESXi 4.0 update 1. UCM 12.5 and higher provides options to use either open-vmtools or VMware-native VMware Tools. VMware vSphere ESXi is mandatory for all virtualized deployments of Cisco Collaboration applications, and is the only supported hypervisor. Not supported. Older versions used 2x80 GB or other configurations as shown in tables above. NOTE: support varies by app and version. Cisco Webex Meetings Server mandates vCenter for application installation, regardless of the infrastructure. 9.0 and later One IM&Presence 1000 user VM either/or one Paging Server 1000 user VM, Cisco Collaboration applications do not support, Cisco Collaboration applications do not support any, Any 3rd-party public cloud offers based on. 3rd-Party VM-based Deployment Tools E.g. Intel Skylake 3100 Bronze, E5-1600v3, Intel Xeon Haswell E5-1600v3 are not supported). Before reading the best practices below, verify support at Supported Editions and Features of VMware vSphere ESXi, VMware vCenter and VMware vSphere Client. VMware Snapshots Always verify with server vendor if a hardware-vendor-specific ESXi image is required. Reminder that for applications to be supported on a storage system, it must meet application requirements for compatibility, latency, usable space and IOPS capacity.
