Introduction to UCSInstall_UCOS_14.0.1.13900-155.sha512.iso

This cryptographic hash-verified ISO image provides the complete operating environment for Cisco UCS B-Series and C-Series servers running Unified Computing System (UCOS) 14.0.1.13900. Certified under Cisco’s Secure Boot Validation Framework (SBVF), the image integrates firmware updates for 23 hardware components including VIC adapters, CIMC controllers, and RAID modules.

Officially released on April 28, 2025, the ISO supports bulk deployment of 64-bit server clusters through Cisco Intersight automation. Mandatory for US federal agencies under FIPS 140-3 compliance requirements, it includes security patches addressing 17 CVEs identified in previous UCOS versions.

Core Technical Specifications

​​1. Security Enhancements​​

  • Implements post-quantum cryptography algorithms for SSHv2 connections
  • Adds certificate pinning for firmware update packages
  • Enforces TPM 2.0-based attestation for boot integrity

​​2. Performance Optimizations​​

  • 38% faster RAID array rebuild times with LSI 9500 controllers
  • 25% reduction in vSwitch packet processing latency
  • Adaptive power management for C480 ML servers

​​3. Protocol Support​​

  • NVMe/TCP end-to-end encryption (RFC 9086 compliance)
  • TLS 1.3 with X25519 key exchange optimization
  • iSCSI CHAP authentication improvements

Compatibility Matrix

Cisco Hardware Series Minimum Firmware Supported OS Versions
UCS B200 M6 Blade Servers 4.1(3a) RHEL 8.4, SLES 15 SP3
UCS C220 M6 Rack Servers 4.0(4d) ESXi 8.0, Ubuntu 22.04 LTS
UCS X-Series Modular System 4.2(1c) Windows Server 2025, CentOS Stream 9

​​Critical Constraints​​:

  • Requires 64GB RAM for full feature activation
  • Incompatible with 3rd-party NVMe storage controllers
  • Mandatory BIOS 2.9.3.17+ for TPM 2.0 functionality

Technical Limitations

  1. Does not support legacy HBA firmware below 8.07.00.00
  2. Limited to UEFI boot mode configurations
  3. Requires 120GB free disk space for installation
  4. Network installation requires 10Gbps+ connectivity

Verified Distribution Channels

This operating image is available through:

  1. ​​Cisco Software Center​​ (Enterprise License Agreement holders)
  2. ​​IOSHub Certified Mirror​​ (https://www.ioshub.net/cisco-ucs-os) with SHA512 validation

Third-party redistribution requires Cisco’s Hardware Compatibility Office authorization. The image undergoes hourly integrity checks against Cisco’s Cryptographic Registry (CCR) during distribution windows.

Technical Support

Cisco TAC provides:

  • 24/7 critical incident support with 1-hour SLA
  • Pre-built Ansible playbooks for cluster deployments
  • Hardware compatibility validation tools

System administrators must reference Cisco UCS 14.0.1 Implementation Guide when upgrading from versions below 13.2. The ISO includes automated health checks that validate 89 system parameters before installation.

This release underwent 6,200 hours of compatibility testing across 42 server configurations. The SHA512 hash verification ensures end-to-end file integrity from download to deployment, utilizing 80-round cryptographic operations compliant with FIPS 180-4 standards.
