Introduction to UCSInstall_UCOS_14.0.1.13900-155.sha512.iso

The ​​UCSInstall_UCOS_14.0.1.13900-155.sha512.iso​​ is a critical deployment package for Cisco’s Unified Computing System (UCS) infrastructure, designed to streamline OS provisioning and firmware synchronization across C-Series rack servers. This SHA-512 verified ISO (released Q2 2025) integrates EN 303 645 cybersecurity standards for EU deployments and complies with NIST SP 800-193 resilience requirements for federal systems.

Certified for ​​Cisco UCS Manager 14.0(1)​​ and later, this build introduces automated driver injection for RHEL 9.3/SLES 15.4 and supports UEFI Secure Boot configurations with quantum-resistant cryptographic modules. It serves as the foundation for hyperconverged deployments using Nutanix AHV or VMware vSphere 8.0U2+.

Technical Enhancements & Functional Updates

Automated Provisioning Engine

  • Implements zero-touch OS deployment via Cisco Intersight Terraform templates
  • Reduces bare-metal provisioning time by 42% through parallel driver injection
  • Resolves 9 edge cases in RAID controller detection during SLES installations

Security Framework

  • Integrates FIPS 140-3 validated OpenSSL 3.1.2 modules
  • Patches CVE-2025-19382 (UEFI bootkit vulnerability)
  • Enables TPM 2.0-based attestation for GRUB2 bootloader

Hardware Optimization

  • Adds native support for Intel Sapphire Rapids CPUs with AVX-512 vector optimizations
  • Improves NVMe-oF performance by 33% through VIC 1500 series offloading
  • Implements adaptive power management for UCS C4800 M6 nodes

Compatibility Matrix

​​Component​​ ​​Supported Versions​​ ​​Minimum Requirements​​
Cisco UCS Hardware C220 M8, C240 M8, C4800 M6 BIOS 4.0(4d)+
Hypervisor Platforms ESXi 8.0U2+, RHEL 9.3+, SLES 15.4 64GB RAM
Management Systems UCS Manager 14.0(1)+, Intersight 3.2+ 10Gbps OOB
Storage Controllers Cisco 12G SAS Modular, NVMe 1.4c RAID 5/6/60/ADG

​​Critical Compatibility Notes​​:

  • Requires UCS VIC 1547 adapters for SR-IOV offloading
  • Incompatible with third-party InfiniBand HCA firmware < v7.2
  • Mandates NTP synchronization within ±2ms for cluster deployments

Deployment Limitations

  1. Does not support legacy UCS C460 M4 hardware
  2. Requires manual configuration for FCoE-based SAN boot scenarios
  3. Limited to 8 simultaneous OS provisioning sessions per UCS domain
