1. Introduction to CmsSpacesEx.exe Software
CmsSpacesEx.exe is a critical component of Cisco Meeting Server (CMS) 3.6.2+ deployments, designed for automated disk space optimization in Windows Server environments. This command-line utility enables administrators to monitor/clear cache partitions and manage virtual meeting recordings stored in CMS clusters.
Developed for Cisco’s UC 14.5 collaboration suite, the tool resolves persistent storage overflow issues reported in CMS 3.3.3 deployments where manual cleanup caused service interruptions. Compatible with CMS clusters running on VMware vSphere 6.5/UCS C240 M5 servers, it ensures compliance with GDPR data retention policies through scheduled purging.
2. Key Features and Improvements
a. Intelligent Storage Management
- Auto-pruning of inactive meeting recordings after 30/90/365-day thresholds
- Real-time monitoring of /var/spool/cisco partitions via SNMP traps
- Multi-tenant isolation for service providers managing shared CMS clusters
b. Security Enhancements
- FIPS 140-2 validated AES-256 encryption for purge logs
- RBAC integration with Cisco Meeting Management 3.6+ consoles
- Digital signature verification for all modified system files
c. Performance Optimization
- Non-disruptive cleanup during low-utilization windows (01:00-04:00 local time)
- 40% faster metadata indexing vs. manual cleanup methods
- Resource throttling to limit CPU usage below 15% during operations
d. Diagnostic Capabilities
- Pre/post cleanup storage snapshots in .CSV format
- Integration with Cisco TAC Collector for RCA workflows
- SMART disk health monitoring with predictive failure alerts
