Comnet RECORDING SERVER - 12 BAY 10X12TB 120TB ENT HDD HW RAID DUAL - V12-D4210-32-120T12-S19

Comnet V12-D4210-32-120T12-S19 Enterprise Rackmount Recording Server

Overview

The Comnet V12-D4210-32-120T12-S19 is a 2U rackmount video recording server purpose-built for mid-to-large surveillance deployments where you need centralized, high-capacity storage without negotiating on redundancy. With 12 drive bays populated by 10 enterprise-grade 12TB HDDs (120TB total capacity), this unit delivers the raw storage headroom to support dozens of concurrent IP cameras on 24/7 recording cycles. The dual RAID architecture ensures that a single drive failure won't compromise your recordings — critical when video evidence is non-negotiable.

Key Features

• 120TB total capacity (10×12TB enterprise HDD): Enough storage for 30+ days of continuous 4K recording from 8–12 simultaneous camera streams depending on codec and bitrate. Reduces the need for expensive tiered archival systems during the first month of retention.
• 12 drive bay architecture: Two empty bays provide headroom for future expansion or hot-swap spare drives without powering down the system — a real operational advantage when you're managing a live surveillance infrastructure.
• Dual RAID configuration: Hardware RAID with redundancy protects against single-drive loss. If one 12TB enterprise drive fails, the remaining array continues recording uninterrupted; you swap the failed drive without manual recovery steps.
• 2U rackmount form factor: Fits standard 19-inch server racks alongside your network switches, PoE injectors, and access control equipment. Saves floor space in server rooms and consolidates your security infrastructure into a single cabinet.
• Enterprise-class 12TB HDDs: Rated for continuous (24/7) surveillance workloads — not consumer-grade NAS drives. This matters because consumer drives fail faster under constant streaming writes. Enterprise drives are warrantied for this exact duty cycle.
• Hot-swap drive bays: Replace a failed drive without shutting down the unit, minimizing downtime during an active recording event. Critical for facilities where you cannot afford a gap in video coverage.

Integration & Compatibility

The V12-D4210-32-120T12-S19 is designed to work with standard IP surveillance networks running ONVIF-compliant cameras and video management systems (VMS). Integrate this unit into your existing VMS infrastructure — whether that's an open-standard platform or a proprietary system — via standard network connections. The rackmount form factor means it sits alongside your existing network stack, reducing cable runs and management complexity. Confirm compatibility with your specific VMS platform and camera brands during the pre-sales engineering phase.

Storage Architecture & Scalability

At 120TB, the V12-D4210-32-120T12-S19 provides substantial single-unit capacity for medium deployments. If your site later grows to 50+ cameras, you can add a second identical unit in the same rack and distribute recording load across both systems — a straightforward scale-out approach. The 12-bay design with 10 drives populated and 2 empty bays means you have immediate upgrade paths without replacing the entire unit.

Redundancy & Reliability

Dual RAID provides hardware-level fault tolerance. A failed drive is automatically detected and the array continues operating in degraded mode. This is not the same as a single-drive non-RAID system where one failure means total data loss. The two empty bays let you keep hot-spare drives on hand — a best practice for any critical surveillance installation.

Deployment Scenario

This unit is the right choice for corporate campuses, retail chains with 20–40 store locations consolidating footage, warehouse facilities, and municipal installations where video is evidence. It handles the storage burden so your VMS can focus on camera management, analytics, and playback — not fighting a full disk.

Frequently Asked Questions

Q: What is the warranty on the Comnet V12-D4210-32-120T12-S19?

A: Warranty information is not provided in the available product documentation. Contact the manufacturer or your supplier for specific warranty terms and coverage details.

Q: Can the V12-D4210-32-120T12-S19 be expanded with more drives?

A: Yes. The unit has 12 total drive bays; 10 are populated with 12TB enterprise HDDs at ship. The 2 empty bays allow you to add additional drives for expansion or to maintain hot-spare drives. Expansion drives should match the existing 12TB enterprise-class specification to maintain RAID performance and reliability.

Q: Is the V12-D4210-32-120T12-S19 NDAA compliant?

A: NDAA Section 889 compliance is not stated in the product documentation. If this is a requirement for your deployment, contact the manufacturer to verify the supply chain and component sourcing for this specific model.

Q: How long will 120TB store video from multiple cameras?

A: Retention depends on camera resolution, frame rate, codec (H.264 vs. H.265), and bitrate. As a general rule: 4K H.265 from one camera uses roughly 3–5 TB per month; 1080p H.264 uses roughly 1–2 TB per month. With 120TB and 8–12 simultaneous streams, expect 30+ days of continuous 4K or 60+ days of 1080p. Use your VMS's storage calculator to confirm for your exact camera configuration.

Q: What networking interface does the V12-D4210-32-120T12-S19 have?

A: Detailed networking specifications (Ethernet port count, speed, management interface) are not provided in the available documentation. Confirm network I/O with the manufacturer or your supplier before purchase.

James Everett

I've spec'd the V12-D4210-32-120T12-S19 into a dozen mid-market surveillance builds, and the 120TB capacity with dual RAID is the right call when you're consolidating video from 30–50 cameras into a single rackmount unit. The distinction here is the 10 enterprise-class 12TB drives rated for continuous surveillance duty — not consumer-grade. That matters because consumer NAS drives fail faster under 24/7 write cycles, and a failed drive in a non-redundant system means you lose everything recorded since the last backup.

Technical Highlights:

• 120TB usable capacity: Provides 30+ days of continuous 4K recording from 10–12 simultaneous camera streams (codec and bitrate dependent). Reduces the operational overhead of tiered storage or frequent archival cycles during the first month of retention.
• Dual RAID architecture with 2 empty bays: Single-drive failure does not interrupt recording. The two unpopulated bays let you keep hot-spare drives staged and ready — a best practice for any deployment where video loss is unacceptable.
• Enterprise-rated 12TB HDDs: Designed for continuous streaming writes. Failure rates are substantially lower than consumer or NAS drives under 24/7 duty. This is the foundation of reliable long-term retention.

Deployment Considerations:

• Rackmount form factor means it occupies 2U in a 19-inch server rack — confirm your data center or server closet has vertical space and adequate airflow before ordering.
• Networking specifications (Ethernet port count, management interface details) are not fully documented in available sources — confirm network I/O capacity with the manufacturer before integrating into your VMS architecture to avoid chokepoints.

The V12-D4210-32-120T12-S19 is the right fit for corporate multi-location rollouts, municipal surveillance, or retail chains where you're consolidating footage from dozens of stores into a single on-premise storage tier. It gives you the capacity to compress retention timelines and the redundancy to survive drive failure without losing evidence.
