PRODUCT COMPARISON
Compare fanless edge servers by deployment requirements
Server-grade features for demanding edge deployments
Every platform combines essential server capabilities for edge computing, including error-correcting memory, high-speed networking and hardware-level management and security provisions.

ECC memory
Error-correcting memory helps detect and correct memory errors to support data integrity and system stability.

10GbE networking
High-speed Ethernet connectivity for bandwidth-intensive workloads and data transfer.

Out-of-band management
Dedicated management connectivity enables remote administration independently of the primary data network.

TPM header
A motherboard TPM header provides a connection for a compatible Trusted Platform Module, subject to configuration.

Route to contract
Buy direct, or through frameworks you already use
2CRSi Edge supplies direct as standard. Where a framework route is needed, it works with partners who hold the routes government buyers use, including CCS TePAS RM6098 (Lots 1–4) and Technology Products 2 RM6147. The frameworks are held by those partners, not by 2CRSi Edge, so buyers already on them do not need to onboard a new supplier. 2CRSi Edge stays responsible for the solution and its lifecycle.

Failed drives
Data retention for failed media:
Defective media retention can be arranged through Tranquil Services, helping organisations maintain control of failed storage devices.

Build assurance
Verified builds before deployment:
Secure build processes, software bills of materials (SBOMs) and acceptance testing can be provided within applicable quality procedures.

Firmware
Controlled firmware and configuration:
Firmware and configuration records support traceability and controlled change throughout the system's service life.
Does your edge server need hardware modifications for deployment?
Most deployment requirements can be addressed through system configuration and software integration. Changes to the physical hardware require a separate engineering assessment.
STANDARD CONFIGURATION
Software configured. Hardware unchanged.
Tranquil Services prepares the server for deployment while retaining the standard hardware design and approved configuration.
Operating system and hypervisor installation
Application and software image deployment
Firmware and system configuration
Asset labelling, branding and identification
ENGINEERING MODIFICATION
Hardware adaptation and integration
Where the deployment requires changes to the physical platform, Tranquil Studio assesses the engineering requirements, technical feasibility and implications before work is agreed.
I/O interfaces and connector layouts
Mounting, brackets and mechanical integration
Power input and delivery requirements
Enclosure modifications and ingress protection
Edge Server FAQs
Technical guidance on compatibility, power, operating conditions, mounting and warranty.
Which edge servers support VMware ESXi?
The FSM-EP4S-50 lists VMware ESXi 7.0 U3g and 8.0 U2b. The FRS-XD2-50 lists VMware ESXi and Microsoft Hyper-V Server. Confirm supported versions and configurations against the relevant product documentation.
What power input do the edge servers require?
All platforms use a 12 V input. The FSM-EP4S-50 uses a DC jack, while the FS-EP3S-50 and FRS-XD2-50 use Phoenix connectors.
Are redundant power supply options available?
The FS-EP3S-50 supports an optional second power supply. The FRS-XD2-50 datasheet describes redundant power and shows two power inputs, but does not list a second supply as an accessory. Contact our engineering team to confirm the available configuration.
What are the operating temperature ranges?
The FSM-EP4S-50 and FS-EP3S-50 are specified for operation from −10°C to 50°C. The FRS-XD2-50 is specified for operation from 0°C to 60°C.
What mounting options are available?
The FSM-EP4S-50 supports optional rack, wall and anti-vibration mounts. The FRS-XD2-50 is designed for full-width rack installation. Contact our engineering team to discuss mounting requirements for other installations.
What warranty and compliance markings apply?
The edge servers carry a three-year warranty and list CE, UKCA, RoHS, FCC and WEEE markings. Confirm any additional compliance requirements relevant to your application before deployment.
How do we buy edge servers for a defence programme?
2CRSi Edge supplies direct as standard. Where a framework route is needed, you can buy through partner-held frameworks. Whichever route you use, 2CRSi Edge stays responsible for the solution and its lifecycle.
Which procurement frameworks can we use?
Our partners’ frameworks include CCS TePAS RM6098 (Lots 1–4) and Technology Products 2 RM6147. These frameworks are held by our partners, not by 2CRSi Edge.
What support is available for procurement and compliance?
The Secure Deployment Package covers deployment, secure build, software bill of materials (SBOM), build records and acceptance testing. Tranquil Services also provides compliance documentation, governance support and procurement and framework support through partners. Ask our team which documents your programme needs.
Size the server to the workload.
Specify the applications, virtualisation requirements, memory, storage, network interfaces and available installation space. Our engineering team will recommend a suitable edge server and configuration based on your workload, connectivity and deployment requirements.
