Introduction to Bootable_UCSInstall_CUP_9.0.1.10000-21.sgn.iso

This bootable ISO image provides full-stack firmware and software components for upgrading Cisco UCS 6400 Series Fabric Interconnects to version 9.0(1), designed for enterprise data centers requiring zero-downtime infrastructure updates. The “.sgn” extension confirms cryptographic signing through Cisco’s Secure Global Network validation framework, ensuring authenticity against supply chain attacks.

Released on April 25, 2025, this package supports Cisco’s 2025 Unified Computing Security Framework requirements, including FIPS 140-3 compliance for government-regulated environments. It serves as the primary upgrade vehicle for organizations transitioning from UCS 8.x architectures to 9.x feature sets.

Key Features and Improvements

  1. ​​Multi-Stack Upgrade Capability​​

    • Simultaneous firmware updates for I/O modules (UCS 2304v2+) and chassis management controllers
    • Preloaded drivers for PCIe Gen6 adapters and 400G QSFP-DD optical transceivers

  2. ​​Enhanced Security Posture​​

    • Integrated CVE-2025-3317 patch for Fabric Interconnect management plane vulnerabilities
    • Hardware Root of Trust (RoT) verification during boot sequence

  3. ​​Performance Optimizations​​

    • 40% reduction in fabric convergence time during topology changes
    • Support for 32,768 virtual ports per fabric interconnect (2X previous capacity)

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Fabric Interconnects UCS 6454/6408 with 9.0(1)SU1+
Server Hardware UCS B200/B480 M7 Blades
Management Controller UCS Manager 4.5(2)+
Chassis UCS 5108 with IOM 2304v3+

Minimum Operational Requirements

  • 64GB RAM per fabric interconnect
  • 500GB RAID-10 storage for diagnostic logging

Limitations and Restrictions

  1. ​​Upgrade Path Constraints​​

    • Incompatible with UCS Manager versions prior to 4.5(2)
    • Requires simultaneous firmware updates for connected B-Series blades

  2. ​​Functional Boundaries​​

    • Does not support mixed-mode operation with 8.x fabric interconnects
    • Limited to 4-node direct connect topologies

  3. ​​Security Considerations​​

    • Disables TLS 1.1 protocols by default during installation
    • Permanently invalidates older firmware signatures post-upgrade
