Recording Storage Architecture and Capacity Planning Solution

📅Apr 8, 2026

Brief：The Recording Storage Architecture and Capacity Planning Solution deploys highly reliable recording services, automatically recording and centrally storing all internal/external line calls, VHF communications, and conference calls, supporting standard formats such as WAV/MP3, ensuring online query for no less than 6 months and supporting long-term archiving. (1) Recording Architecture: Recording collection service (horizontally scalable) → Recording files stored in object storage/file storage → Metadata entry into database (call ID, position, timestamp, calling/called party, VHF channel, etc.) → Full-text search/playback by time point. (2) Tiered Storage and Archiving: Online tier ensures ≥6 months of high-frequency query; archive tier for longer-term retention for future reference. Supports policy-based automatic archiving, verification, and recovery to meet audit and investigation evidence needs. (3) Capacity Planning Method: Calculated based on "concurrent channels × average daily call duration × bitrate × retention days × redundancy factor (≥1.3)"; provides expansion thresholds, expansion procedures, and non-disruptive expansion solutions (adding storage nodes/buckets/disk arrays).
