​​1. Introduction to Bootable_UCSInstall_CER_9.0.0.98700-9.sgn.iso​​

​​Bootable_UCSInstall_CER_9.0.0.98700-9.sgn.iso​​ is Cisco’s disaster recovery boot image for Unified Computing System (UCS) environments, designed to restore critical infrastructure components during catastrophic failures. Released in Q1 2025 as part of Cisco UCS Manager 9.0.0 updates, this ISO provides a self-contained recovery environment for fabric interconnects, I/O modules, and UCS Manager software restoration.

The software bundle integrates infrastructure firmware packages validated for Cisco UCS 6400/6500 Series Fabric Interconnects and 2200/2300 I/O Modules. It supports hybrid deployments by combining on-premises UCS restoration with cloud-based configuration backups from Webex Hybrid Cloud solutions.

​​2. Key Features and Improvements​​

​​Critical enhancements in version 9.0.0 include:​​

​​Disaster Recovery Architecture​​

  • ​​TLS 1.3 Secure Boot Verification​​: Ensures image integrity through cryptographic signature checks before initiating recovery.
  • ​​Multi-Component Restoration​​: Simultaneously recovers fabric interconnect firmware (v9.0.0b), I/O modules (v4.2.3e), and UCS Manager configurations.
  • ​​FIPS 140-3 Compliance​​: Meets U.S. federal standards for encrypted backup restoration workflows.

​​Operational Efficiency​​

  • ​​Smart Fabric Recovery​​: Auto-detects mismatched firmware versions across chassis and aligns them with golden configurations.
  • ​​Dual-Mode Restoration​​: Supports both USB-localized recovery and network-based deployments via PXE boot.
  • ​​Webex Cloud Sync​​: Restores UCS domain policies from Webex Hybrid Cloud backups created within 72 hours of failure.

​​Security Enhancements​​

  • ​​Certificate Transparency Logging​​: Validates TLS certificates against public logs during cloud backup retrieval.
  • ​​Hardware Root of Trust​​: Enforces Secure Boot on Cisco UCS S-Series servers using TPM 2.0 modules.

​​3. Compatibility and Requirements​​
