Comnet MGMT SERVER - 4 BAY 4X480GB SSD XEON E-2276G 32GB 2X240GB M.2 O - M4-E2276G-32-D1920G480N-S19

Comnet M4-E2276G-32-D1920G480N-S19 Xeon Surveillance Management Server

Overview

The Comnet M4-E2276G-32-D1920G480N-S19 is a 4-bay SSD-based management server purpose-built for mid-to-large surveillance deployments and edge VMS workloads. Paired with an Intel Xeon E-2276G processor, 32GB of system memory, and 1.92TB of hot-swap SSD capacity (4×480GB), this server handles continuous video ingest, transcoding, and playback across dozens of networked cameras. Windows Server 2019 Standard arrives pre-installed, eliminating OS configuration delay. The dual 10GbE SFP+ interfaces separate management traffic from video streams, while redundant 350W power supplies ensure uptime if a PSU fails.

Key Features

• Intel Xeon E-2276G Processor: Six-core hyperthreading delivers sustained multi-stream video processing—real benefit is avoiding CPU bottlenecks on simultaneous recording and playback. Counts when you're running both live view transcoding and archive retrieval at the same time.
• 1.92TB Hot-Swap SSD Storage (4×480GB): SSD-based storage eliminates the I/O ceiling of spinning disk—write latency stays under 5ms even under peak load. For 24/7 multi-camera recording, this means no dropped frames during high-bitrate ingest bursts. Each bay supports individual drive replacement without shutdown.
• 2×240GB M.2 NVMe OS Drives: Mirrored OS boot drives prevent single-point-of-failure on the system partition. If one M.2 fails, Windows Server continues running from the mirror; you swap the failed drive at your next service window.
• Dual 10GbE SFP+ + Dual 1GbE RJ45 Network: 10GbE lanes handle uncompressed or lightly compressed video feeds from core switches without saturation. The 1GbE ports isolate management traffic (SSH, web UI, NTP) from video planes. Critical when a single misconfigured camera shouldn't starve your entire recording appliance.
• Redundant 350W Power Supplies: Hot-swappable PSU design means you can replace a failed supply without powering down the server. In a 24/7 surveillance mission, this eliminates the need for scheduled maintenance windows just to swap power hardware.
• Windows Server 2019 Standard Pre-Installed: Licensing and image already baked in—deploy to your VMS software immediately. No license key hunting, no imaging delays. Reduces time-to-recording by days in large integrations.

Integration & Compatibility

The M4-E2276G-32-D1920G480N-S19 runs any ONVIF-compliant VMS platform—Milestone XProtect, Genetec SecurityCenter, Bosch Divar, Hikvision iVMS—as long as the VMS supports Windows Server 2019 Standard as a host OS. The dual 10GbE SFP+ ports integrate directly into core network switches; many Comnet deployments pair this server with Comnet-branded PoE switches to create a complete in-building video backbone. The server's four SSD bays and OS drive redundancy make it suitable for both primary recording (main site) and failover/archive roles in distributed architectures. Confirm your VMS licensing model covers Windows Server 2019 Standard before purchase.

Storage and Scalability Notes

Total usable storage is 1.92TB (4 bays × 480GB) plus OS mirroring on the M.2 drives. For retention math: at 8 Mbps per camera (H.264 1080p 30fps), one 480GB bay holds roughly 13 hours of single-camera footage; the four-bay stack holds ~52 hours per camera. In a 16-camera system at 8 Mbps per stream (128 Mbps aggregate), the full 1.92TB retention drops to ~3.2 hours. For longer retention, external SAN or NAS attachment via the 10GbE ports extends capacity without internal redesign.

Power and Environmental

The dual 350W PSUs deliver enough headroom to support the full CPU, memory, and four-bay SSD load simultaneously. Operating environment is a standard commercial server range (typically 10°C–40°C ambient). In hot climates or dense server racks, ensure adequate airflow across the front intake; the redundant PSU design implies internal cooling also supports failover operation.

Frequently Asked Questions

Q: What's the warranty on the M4-E2276G-32-D1920G480N-S19?

A: 5-year manufacturer warranty covering parts and labor on the server hardware. Confirm Windows Server 2019 Standard licensing terms separately with your VMS vendor or Microsoft.

Q: Can the M4-E2276G-32-D1920G480N-S19 handle 32 camera streams simultaneously?

A: Depends on resolution, bitrate, and codec. At 1080p H.264 ~8 Mbps per stream, the Xeon E-2276G and 10GbE pipes handle 32+ streams comfortably (aggregate ~256 Mbps). At 4K per camera, expect 12–16 streams before CPU or network saturation; test your exact codec/resolution mix in your VMS before deployment.

Q: Is the M4-E2276G-32-D1920G480N-S19 suitable for failover or archive-only roles?

A: Yes. The redundant PSU, mirrored OS drives, and four-bay SSD capacity make it equally suitable for secondary recording (failover) or centralized archive. Pair it with a replication strategy in your VMS to copy video from the primary server to this unit's storage.

Q: How do I connect the 10GbE SFP+ ports?

A: The two SFP+ ports use small-form-factor transceivers (not included). Order compatible SFP+ modules (e.g., SR, LR, or DAC based on cable distance to your core switch). Most core switches support 10GbE SFP+ line-rate throughput; confirm your switch's SFP+ port licensing before purchase.

Q: Can I upgrade the RAM or swap the Xeon processor?

A: The 32GB RAM is factory-installed; upgrading requires opening the chassis and is not a field-swap procedure. The Xeon E-2276G is soldered or socket-locked; processor replacement is not supported. Plan storage and processing capacity during the purchase phase.

The Comnet M4-E2276G-32-D1920G480N-S19 is built for integrators running mid-scale surveillance backends—think 20–50 camera deployments where frame drops or transcoding delays kill your SLA. The dual 10GbE SFP+ ports are the real win here; you separate video ingest from management traffic, and a single misconfigured camera doesn't starve your entire recording appliance.

Technical Highlights:

• Intel Xeon E-2276G (6-core HT): Delivers 50–100 fps sustained H.264 transcoding per core under load—meaningful when you're running live view + archive retrieval simultaneously. The 32GB RAM keeps your VMS application, OS, and buffer caches happy without disk swaps.
• 1.92TB Hot-Swap SSD (4×480GB): SSD write latency under 5ms means zero frame drops on burst ingest. Spinning disk would hit 10–20ms latency under peak load; SSD eliminates that bottleneck. For 32 cameras at 8 Mbps each (256 Mbps aggregate), this is non-negotiable.
• Redundant 350W PSUs + Mirrored M.2 OS Drives: Both power supplies fail independently; if one dies, the server keeps running. Both M.2 drives mirror the Windows Server OS; if one fails, boot continues from the mirror. In 24/7 surveillance, downtime costs money—this design cuts planned maintenance to zero unless hardware actually breaks.
• Dual 10GbE SFP+ + Dual 1GbE RJ45: 10GbE lanes handle ~1.25GB/sec throughput—enough for 150+ simultaneous 8 Mbps streams. The 1GbE ports carry SSH, web UI, syslog, and NTP traffic, isolated from video planes. Prevents management protocol storms from impacting recording.

Deployment Considerations:

• SFP+ modules (transceivers) are not included—order them separately based on your core switch and cable distance. Budget $100–$300 per transceiver depending on distance and type (SR, LR, DAC).
• Storage math: at 8 Mbps per camera, the full 1.92TB holds ~52 hours per single camera. In a 16-camera system, retention drops to ~3 hours. Plan NAS or SAN extension immediately if you need retention beyond 4 hours across dozens of cameras.
• Windows Server 2019 Standard is end-of-support in January 2027—plan a migration to Windows Server 2022 Standard or newer in the 5–6 year window if you need extended lifecycle support.

This server excels in private facility deployments (universities, corporate campuses, distribution centers) where network bandwidth is controlled and uptime SLAs are tight. Skip it if you need cloud-first architecture or if your camera count exceeds 60 streams at high resolution—consider scaling horizontally with multiple smaller appliances instead.
