Introduction to CUCSRSV_11.5_500_user_v1.2.ova

This Cisco-certified virtual appliance provides disaster recovery capabilities for Unified Communications Manager 11.5 deployments supporting up to 500 users. Designed as a preconfigured Open Virtual Appliance (OVA), it enables rapid restoration of critical collaboration services during system failures or data corruption events. The package contains optimized configurations for VMware ESXi 6.7+ environments and integrates with Cisco’s Security Operations Framework for encrypted backup restoration.

Certified for use with Cisco UCS C-Series rack servers and HyperFlex hyperconverged infrastructure, this recovery solution maintains compatibility with IM & Presence Service 11.5(1) and Emergency Responder 11.5 systems. The “v1.2” revision includes updated cryptographic modules compliant with FIPS 140-3 standards, released on May 10, 2025.
