​​Introduction to UCSInstall_UCOS_ES_6.1.3.3219-1.sgn.iso​​

This 4.7GB SHA512-signed ISO provides the complete installation environment for Cisco UCS Embedded Operating System (UCOS) Enterprise Security Edition 6.1(3), specifically designed for Cisco UCS C480 M7 and C220/C240 M6 rack servers. The “_sgn” suffix confirms FIPS 140-3 compliant digital signature verification through Cisco’s Cryptographic Object Signing process, making it suitable for defense and financial sectors requiring NIST SP 800-193 compliance.

Certified for deployment on VMware ESXi 7.0 U2+ and KVM 4.0+ hypervisors, this ISO integrates hardware-accelerated encryption modules for Cisco UCS VIC 1500 Series adapters. It resolves 12 critical CVEs identified in previous UCOS 6.0.x releases, including memory leakage vulnerabilities in TLS 1.3 session resumption (CVE-2025-19372-class).

​​Key Technical Enhancements​​

​​Security Architecture​​

  • Quantum-resistant key encapsulation using NIST PQC Round 4 finalists (CRYSTALS-Kyber/FrodoKEM)
  • Hardware Root of Trust implementation for Secure Boot with TPM 2.0 binding
  • Runtime memory protection against buffer overflow attacks via Intel CET technology

​​Performance Optimization​​

  • 40% faster NVMeoF throughput through VIC 1500 Series RDMA optimizations
  • Adaptive power management reducing idle consumption by 18% on C480 M7 chassis
  • Real-time telemetry collection with 10μs timestamp precision for AIOps integration

​​Protocol Support​​

  • SR-IOV 3.1 implementation supporting 512 virtual functions per adapter
  • NVMe/TCP acceleration with TLS 1.3 encrypted storage traffic
  • Precision Time Protocol (PTP) Grandmaster Class C compliance

​​Verification & Acquisition​​

Validate cryptographic integrity using:

bash复制
openssl sha512 UCSInstall_UCOS_ES_6.1.3.3219-1.sgn.iso


Cisco partners with active service contracts can download through Cisco Software Central. Verified copies are available via authorized distributors including IOSHub.net, which maintains original SHA512 hashes and Cisco digital signatures.
