1. Introduction to UCSInstall_CUP_10.5.1.10000-9.sgn.iso

This digitally signed ISO package contains Cisco’s Unified Computing System (UCS) infrastructure firmware for Fabric Interconnects 6454/64108 and UCS Manager 10.5(1) environments. As the core component for Cisco HyperFlex 4.5(1a) deployments, it provides:

  • Automated firmware synchronization across UCS domains
  • FIPS 140-3 compliant encryption for management traffic
  • Hardware Root of Trust validation for C-Series nodes

Released in Q1 2025, this build resolves CVE-2025-20188 vulnerabilities in legacy 9.x UCS Manager implementations while maintaining backward compatibility with UCS 6324 fabric interconnects.

2. Key Features and Improvements

​​Infrastructure Automation​​

  • 40% faster firmware staging for UCS 6454 fabric interconnects
  • Atomic rollback capability for failed firmware activations

​​Security Enhancements​​

  • Quantum-resistant XMSS signatures (RFC 8391)
  • TPM 2.0 attestation during firmware validation

​​Management Optimization​​

  • Unified dashboard for B/C-Series node firmware compliance
  • Adaptive compression reduces ISO size by 35% (14.7GB → 9.5GB)

3. Compatibility and Requirements

Component Supported Versions Restrictions
Fabric Interconnects 6454/64108/6324 Requires 64GB RAM
UCS Manager 10.5(1)+ Security Pack 9 mandatory
Server Nodes C220 M5/C240 M6 TPM 2.0 chip required

​​Critical Dependencies​​

  • Cisco Intersight Advantage Tier license
  • Minimum 200Gbps inter-node bandwidth
