Introduction to CUCSRSV_12.5_v1.0.ova

This critical virtualization package enables streamlined deployment of Cisco Unified Computing System (UCS) Central 1.3 management platform, designed for multi-domain orchestration in large-scale data centers. As an Open Virtual Appliance (OVA) template, it provides preconfigured resource allocation optimized for VMware ESXi 7.0+ environments, implementing Cisco’s validated design for centralized infrastructure management.

Certified for environments managing 50+ UCS domains, the package supports firmware lifecycle management across Cisco UCS B-Series Blade Servers and C-Series Rack Servers running UCS Manager 2.1(2a) or later. Released on April 25, 2025 (build 1.0), it incorporates critical security patches addressing CVE-2025-3281 vulnerabilities identified in previous UCS Central releases.
