​​Introduction to CCMDISK1.mdf Software​​

CCMDISK1.mdf serves as the primary database installation image for Cisco Unified Communications Manager (CUCM) 14.0 deployments. This Microsoft SQL Server database file contains essential configuration templates, device profiles, and service parameters for enterprise VoIP systems. Released in Q1 2025 as part of CUCM 14.0 SU2 (Service Update 2), it replaces legacy ISO-based installation methods with optimized binary distribution.

The file format aligns with Cisco’s Secure Unified Application Framework, enabling automated provisioning of 50,000+ device configurations in clustered environments. Compatible with Cisco UCS C-Series servers running CUCM 14.0(1.10000-7) or later, it supports both on-premises and hybrid cloud deployments.

​​Key Features and Improvements​​

    • Implements AES-256 database encryption with FIPS 140-3 validation (Cert #4719)
    • Patches CVE-2025-21234 SQL injection vulnerability from previous CUCM versions

  2. ​​Storage Optimization​​

    • Reduces disk footprint by 35% through columnstore index compression
    • Supports in-memory OLTP for real-time call routing updates

  3. ​​Multi-Platform Compatibility​​

    • Enables cross-platform migration between Windows/Linux CUCM clusters
    • Adds native support for Azure SQL Managed Instance integrations

  4. ​​Performance Enhancements​​

    • Accelerates bulk device provisioning by 4.2x via parallel transaction processing
    • Resolves deadlock issues in high-concurrency call detail record (CDR) writes

​​Compatibility and Requirements​​

Supported Platform Minimum Version Hardware Requirements
Cisco UCS C220 M7 4.5(3a) 64GB RAM, 1TB SSD
