EC266D4-4L

High-Performance ATX Server Motherboard for Edge and Storage Nodes with the EC266D4-4L

The EC266D4-4L is an ATX server motherboard built on the Intel C266 platform for a single LGA1700 Xeon-class CPU, targeting branch compute, storage-centric appliances, and industrial systems that require deterministic I/O and remote management. The EC266D4-4L combines enterprise manageability via integrated IPMI/BMC with a balanced expansion layout suited to mixed networking, accelerator, and storage controller deployments.

With DDR5 ECC DIMM support across 4 slots (up to 128GB), the EC266D4-4L provides a memory architecture aligned to always-on services where data integrity and predictable latency matter. PCIe 5.0 expansion (x16 and x8) plus 2 additional PCIe 4.0 x4 links enables high-throughput add-in cards such as capture, NVMe HBA, or security accelerators without constraining lane bandwidth. For storage, 14 SATA ports and dual PCIe 4.0 x4 M.2 (M-Key) sockets allow SATA-dense arrays while retaining fast boot or cache tiers; RAID 0/1/5/10 support fits common resiliency profiles.

Why Choose the EC266D4-4L?

The EC266D4-4L is engineered for high I/O density per rack unit, making it suitable for compact enclosures where ports, lanes, and manageability must scale without adding complexity. Its 4x Intel I210 1GbE interfaces, AST2600 BMC, and TPM readiness provide an enterprise deployment logic focused on secure remote operation, consistent provisioning, and dependable lifecycle management across distributed sites.

ASRock Rack designs platforms with a server-first focus on signal integrity, validated firmware, and long-run availability, aligning with modern data centre standards for out-of-band management, ECC memory operation, and serviceable I/O layouts in edge and micro-datacentre environments.

Key Applications:

Edge and branch virtualization nodes
Network services and security appliances
SATA-dense NAS and backup servers
Industrial control and monitoring servers
Data acquisition and logging platforms

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your EC266D4-4L project requirements and an extended warranty option up to 6 years to secure long-term deployments in branch, industrial, and storage-focused environments.
