Introduction to cucm_im_p_11.0_vmv8_v1.1.ova

The ​​cucm_im_p_11.0_vmv8_v1.1.ova​​ is a preconfigured virtual appliance for deploying Cisco Unified Communications Manager IM & Presence (IM&P) 11.0 on VMware vSphere environments. Designed for enterprises requiring real-time messaging and presence services, this Open Virtualization Format (OVA) template streamlines deployment of Cisco’s collaboration infrastructure while maintaining compatibility with legacy communication systems.

As part of Cisco’s virtualization strategy for collaboration suites, this image supports integration with Unified Communications Manager 11.x clusters, enabling administrators to consolidate instant messaging, SIP-based presence, and chat room services on VMware ESXi 6.7+ platforms. The ​​vmv8_v1.1​​ designation indicates optimizations for 8th-generation vSphere virtual hardware, including enhanced vCPU allocation and memory ballooning controls.

Key Features and Improvements

  1. ​​Virtualization-Optimized Architecture​​
    Implements VMware paravirtualized SCSI controllers and VMXNET3 network adapters to reduce I/O latency by 22% compared to previous OVA templates. Supports hot-add memory configurations for dynamic resource scaling during peak usage.

  2. ​​Security Compliance​​
    Pre-hardened configuration aligns with CIS Benchmark Level 2 standards, disabling unnecessary services like XMPP file transfer protocols by default. Includes TLS 1.2 cipher suite prioritization for secure inter-node communication.

  3. ​​Legacy System Integration​​
    Maintains backward compatibility with Cisco Unified Contact Center Express (UCCX) 10.6+ through SIP presence APIs, enabling hybrid deployments during migration phases.

  4. ​​Resource Efficiency​​
    Reduces baseline memory consumption to 16GB through kernel-level optimizations, supporting deployments on mid-range UCS C220 M5 servers.

Compatibility and Requirements

Supported Platforms

​​Category​​ ​​Supported Systems​​ ​​Minimum Version​​
Virtualization VMware ESXi 6.7 U3, 7.0 U2 ESXi 6.7 Update 3
Collaboration Core CUCM 11.0(1)SU2, CUC 11.0(1)SU1 11.0(1)aSU1
Hardware Cisco UCS C220/C240 M5 servers BIOS 4.1(3c)

Compatibility Notes

  • ​​Unsupported Hypervisors​​: Incompatible with Microsoft Hyper-V/KVM due to VMware-specific drivers
  • ​​Storage Limitations​​: Requires thick-provisioned eager-zeroed disks for optimal performance
