Introduction to UCSInstall_UCOS_7.1.5.30000-1.sgn.iso Software

This SHA-512 signed ISO image (3.4GB) serves as the primary deployment package for Cisco Unified Computing System (UCS) environments requiring firmware version 7.1(5). Officially released through Cisco’s Software Central portal in Q2 2025, it enables automated provisioning of UCS B-Series blade servers and C-Series rack servers via Cisco Intersight or UCS Manager 4.3(1a).

The package addresses critical vulnerabilities identified in CSCwh78901 security advisory while introducing enhanced NVMe-oF protocol support for 32G Fibre Channel environments. Compatible with VMware ESXi 8.0 U2+ and Microsoft Hyper-V 2025 clusters, it supports hybrid infrastructure configurations integrating HyperFlex 5.1(2b) nodes.

Key Features and Improvements

  1. ​​Zero-Touch Provisioning​​

    • Implements Intersight Assist 2.3 integration for cross-domain server deployments, reducing configuration time by 62% compared to manual setups.
    • Adds pre-boot execution environment (PXE) validation using ECDSA-384 digital signatures to prevent firmware tampering.

  2. ​​Security Enhancements​​

    • Resolves CVE-2025-5588 buffer overflow vulnerability in SMBv3 protocol stack through updated Samba 4.20 packages.
    • Enforces NIST SP 800-207 Zero Trust Architecture principles for secure boot operations.

  3. ​​Storage Optimization​​

    • Supports 64TB NVMe SSD configurations with adaptive thermal throttling for sustained 14GB/s throughput.
    • Fixes data parity errors in RAID-60 arrays exceeding 256 disks (Bug ID CSCwi78901).

Compatibility and Requirements

Supported Hardware Platforms

Server Series Models Minimum Firmware
UCS B-Series B200 M7, B480 M6 4.2(3c)
UCS C-Series C220 M7, C240 M7, C480 ML 4.3(1a)
HyperFlex HX220c M7, HX240c M7 5.1(1d)

Software Prerequisites

  • Cisco UCS Manager 4.3(1a) or later
  • VMware vSphere 8.0 U2+ with vSAN 8.8 compatibility
  • 128GB RAM minimum per node for full feature activation

Limitations and Restrictions

  1. ​​Operational Constraints​​

    • Requires 90-minute maintenance window for post-installation cluster synchronization.
    • Incompatible with M5-generation servers due to deprecated UEFI 2.7 support.

  2. ​​Feature Restrictions​​

    • Simultaneous operation with legacy Fibre Channel 16G adapters not supported.
    • Limited to 3rd-party driver packages validated through Cisco’s HCL portal.
