Key Benefits

🚀 High performance, power-efficient platform

Built on AMD EPYC 8004 “Siena”, the SIENAD8-2L2T is optimized for edge and scale-out workloads that demand strong performance per watt—perfect for virtualization, containers, SD-WAN, firewalls, and storage nodes.

🔌 Extreme I/O flexibility with PCIe 5.0 & CXL

With five PCIe 5.0 slots (including three CXL-ready x16), you get huge bandwidth for:

• High-speed NICs (25/40/100GbE and beyond)

• NVMe HBAs and RAID controllers

• GPUs, DPUs, AI accelerators, and FPGAs

You’re investing in a platform built for next-gen expansion.

📦 Dense, ultra-fast storage options

The combination of 2 × MCIO PCIe 5.0 x8 and 2 × M.2 PCIe 5.0 x4 makes this board ideal for:

• All-NVMe storage servers

• Cache-accelerated file or backup servers

• Hyperconverged infrastructure (HCI) nodes

Use M.2 for OS/cache and MCIO for NVMe backplanes to achieve extremely high IOPS and low latency.

🌐 Onboard 10GbE + 1GbE networking

Dual 10GbE plus dual 1GbE give you a flexible network setup out of the box:

• 10GbE for high-throughput data paths

• 1GbE for management, backup, or segregated traffic

No need for a basic add-in NIC just to deploy.

🧠 DDR5 RDIMM for bandwidth-heavy workloads

Eight DDR5 RDIMM slots let you build high-capacity, high-bandwidth memory configurations, ideal for:

• Virtualization hosts (VMware, Hyper-V, Proxmox, etc.)

• In-memory caching and databases

• Microservices and heavily parallel workloads

🛠 Enterprise-grade remote management

With integrated IPMI and ASPEED AST2600 BMC, you get:

• KVM over IP (remote console)

• Remote power on/off and resets

• Hardware sensor monitoring (temps, voltages, fans)

Perfect for remote sites and edge deployments where you can’t always be on-site.

Who Is the SIENAD8-2L2T For?

This motherboard is an excellent fit for:

• System integrators & OEMs building custom network/security/storage appliances

• SMBs and enterprises needing compact edge servers or micro–data center nodes

• Service providers / MSPs deploying virtualization or HCI clusters at customer sites

• Telco, ISP, and industrial environments that demand reliable, power-efficient EPYC platforms in a standard ATX chassis

If you want PCIe 5.0, onboard 10GbE, and a future-proof EPYC 8004 base in a familiar ATX form factor, this board hits the sweet spot.
