Data Storage
Every EQ deployment needs local storage for waveform and metrics data. Optional remote storage provides long-term retention and cross-site access. EQ Coherence is storage-agnostic; choose the media and architecture that fits your facility.
Local Storage
Local storage is required for all deployments. It buffers incoming data and provides near-term access through EQ Sight. Larger media extends local retention and reduces write wear.
| Media | Interface | Available On | Typical Capacity |
|---|---|---|---|
| microSD card | USB adapter | Compulab IOT-GATE / IOT-DIN | Up to 1.5 TB |
| microSD card | Direct slot | Toradex-based gateways (planned) | Up to 1.5 TB |
| USB SSD | USB 3.0 | Any gateway with USB 3.0 port | Up to 4 TB |
| NVMe SSD | M.2 / PCIe | AGX Orin, Thor | Up to 4 TB |
CPOW data generates approximately 30 GB per day for a typical 3-phase deployment (losslessly compressed int32 waveform data; lighter configurations use less). Industrial gateways ship with 1.5 TB storage, providing approximately 7 weeks of retention. Lab gateways ship with 1 TB, providing over 5 weeks.
See Storage Media for capacity planning, recommended hardware, formatting, and swap procedures.
Remote Storage
Remote storage replicates data from EQ Coherence to a remote server for long-term retention, backup, and cross-site access (typical sync latency ~1 min). It is optional for all deployments except EQ-hosted AI, which requires it. Contact us for details on remote storage options.
| Option | Where | Best For |
|---|---|---|
| EQ-hosted | Dedicated EQ server | Long-term archival, cross-site analytics, EQ-hosted AI |
| Customer-hosted | Customer NAS or data center | Data residency requirements, integration with existing IT infrastructure |
When remote storage is enabled, EQ Coherence retains local data for near-term access while the server handles archival. Both copies are accessible through EQ Sight.
