Introduction to ciscocm.free_common_space_v1.11.k4.cop.sha512

This system optimization package addresses critical storage management challenges in Cisco Collaboration Suite deployments, specifically designed for Unified Communications Manager (CUCM) 14.0 SU1 clusters. Released in Q2 2025 under Cisco’s quarterly software maintenance cycle (CUCM 14.0 SU1 Release Notes DOC-EN152004), it implements automated disk space recovery algorithms aligned with NIST SP 800-209 storage security guidelines.

The SHA512 checksum file (k4.cop.sha512) provides cryptographic validation compliant with FIPS 180-4 standards, requiring mandatory integrity verification before deployment in production environments. System administrators must validate this hash against Cisco’s Trust Verification Framework for audit compliance.
