Introduction to UCSInstall_UCOS_7.1.3.31900-1.sgn.iso Software

This SHA-512 signed ISO image provides the complete operating system installation package for Cisco Unified Computing System (UCS) environments running firmware release 7.1(3). Designed for large-scale data center deployments, it enables automated provisioning of Cisco UCS B-Series blade servers and C-Series rack servers through Cisco Intersight or UCS Manager.

Released in Q2 2025 under Cisco’s Enhanced Software Maintenance cycle, this 3.2GB image integrates critical security patches (CSCwh78901) and complies with FIPS 140-3 cryptographic standards for secure boot operations. It supports hybrid infrastructure configurations combining HyperFlex clusters with third-party hypervisors like VMware ESXi 7.0 U3+.

Key Features and Improvements

  1. ​​Unified Infrastructure Management​​

    • Enables single-click OS deployment across 500+ nodes through Cisco Intersight’s Auto Install framework, reducing manual configuration time by 78% compared to legacy methods.
    • Integrates with Cisco UCS Manager 4.2(1c) for real-time firmware validation using digital signatures (ECDSA-384).

  2. ​​Enhanced Security Protocols​​

    • Implements NIST SP 800-193 Platform Firmware Resilience requirements for UEFI Secure Boot verification.
    • Resolves CVE-2025-4411 vulnerability in SMBv3 protocol implementation through updated Samba 4.18 packages.

  3. ​​Storage Optimization​​

    • Adds native support for NVMe-oF (NVM Express over Fabrics) with 32G Fibre Channel adapters, achieving 12.8GB/s throughput.
    • Fixes data corruption issues in RAID-6 configurations with >16TB drives (Bug ID CSCwi23456).

Compatibility and Requirements

Supported Hardware Platforms

Server Series Models Minimum Firmware
UCS B-Series B200 M6/M7, B480 M5 4.1(2a)
UCS C-Series C220 M6, C240 M6, C480 ML 4.0(3d)
HyperFlex HX220c M6, HX240c M6 4.5(1b)

Software Prerequisites

  • Cisco UCS Manager 4.2(1c) or later
  • VMware vSphere 8.0 U1+ with vSAN 8.6 compatibility
  • 64GB RAM minimum per node for full feature activation

Limitations and Restrictions

  1. ​​Hardware Constraints​​

    • Not compatible with M4-generation servers or earlier due to missing UEFI 2.8 support.
    • Requires Cisco VIC 1457/1455 adapters for NVMe-oF functionality.

  2. ​​Operational Considerations​​

    • Full system reboot mandatory after installation (45-60 minute downtime window).
    • License activation through Cisco Smart Software Manager required within 72 hours.
