Introduction to UCSInstall_UCOS_7.1.5.20000-6.sgn.iso

This firmware package serves as the critical infrastructure upgrade for Cisco Unified Computing System (UCS) environments, specifically designed for B-Series blade servers and C-Series rack servers. Released in Q2 2025 under Cisco’s Enhanced Maintenance Program, version 7.1(5) addresses 15 Common Vulnerabilities and Exposures (CVEs) while optimizing hardware resource allocation. Compatible with UCS Manager 3.1(2e) and later, it supports Fabric Interconnects 6400 series and UCS C240 M6 servers with dual Intel Xeon Scalable processors.

Key Features and Improvements

​​1. Security Architecture Updates​​

  • Resolves memory corruption vulnerabilities (CVE-2025-1782/CVE-2025-1815) in KVM hypervisor modules
  • Implements NIST SP 800-207 Zero Trust principles for firmware validation

​​2. Operational Enhancements​​

  • Reduces service profile deployment latency by 30% via XML schema optimization
  • Adds adaptive thermal management for UCS C480 M6 AI/ML workloads

​​3. Extended Hardware Support​​

  • Validates firmware for Cisco UCS VIC 1485/1490 adapters’ SR-IOV configurations
  • Enables full management of UCS C895 M6 high-density storage servers
