Lenovo 7M17A04000 Thinksystem D2 10GB 8-PORT Eiom SFP+

Lenovo 7M17A04000 ThinkSystem D2 10GbE 8-Port SFP+ EIOM

The Lenovo 7M17A04000 is an Ethernet expansion I/O module (EIOM) designed for the Lenovo ThinkSystem D2 chassis, delivering eight 10GbE SFP+ ports to increase north-south bandwidth in blade server environments without adding external switching hardware. If your D2 chassis is running short on fabric bandwidth or you need to segment workloads onto dedicated 10G uplinks, this is the module to reach for.

Key Features

• 8x SFP+ Ports (10GbE): Eight dedicated 10 Gigabit Ethernet ports via SFP+ transceivers — each blade gets high-throughput connectivity without contention from shared mid-plane bandwidth, which matters when running storage-intensive or latency-sensitive workloads across the chassis.
• SFP+ Interface: SFP+ supports both copper (Twinax DAC) and fiber optic connections, so you can reach top-of-rack switches with short DAC cables at low cost or extend to fiber uplinks for longer runs — no re-cabling when your rack layout changes.
• Chassis-Native Expansion (EIOM Form Factor): As an I/O expansion module, this installs directly into the D2 chassis I/O bay, eliminating the need for external pass-through modules or additional rack-mount switches and keeping your cable count clean.
• 10GbE Throughput: 10 Gigabit per port is sufficient for most enterprise compute and high-bandwidth video recording workloads. If your environment demands 25GbE or 40GbE fabric, evaluate higher-speed EIOM options in the ThinkSystem family.
• Manufactured in Mexico (Country of Origin: MX): MX origin is relevant for TAA-sensitive procurement contexts — verify TAA compliance with your Lenovo account team for specific contract requirements before purchase.

Integration and Compatibility

The 7M17A04000 is engineered for the ThinkSystem D2 chassis platform. Verify chassis firmware revision and supported EIOM slot compatibility against the Lenovo ThinkSystem compatibility matrix before ordering — not every D2 configuration supports all EIOM variants. SFP+ transceiver selection (DAC, SR, LR) is separate and must match your switch port type and cable plant. Weight is 2.75 lb; installed dimensions are 18.50 x 13.20 x 4.30 in — confirm I/O bay clearance before deployment.

Frequently Asked Questions

Q: What chassis does the 7M17A04000 support?

A: The 7M17A04000 is designed for the Lenovo ThinkSystem D2 blade chassis. Verify slot compatibility and firmware requirements with the Lenovo ThinkSystem compatibility matrix before ordering.

Q: What transceiver types are compatible with the SFP+ ports?

A: SFP+ ports support both Direct Attach Copper (DAC/Twinax) cables and fiber optic transceivers (SR, LR, etc.). Transceiver selection depends on your switch infrastructure and cable plant — transceivers are purchased separately.

Q: Is the 7M17A04000 TAA compliant?

A: Country of origin is Mexico (MX). TAA compliance status for specific government contract vehicles should be confirmed directly with Lenovo prior to purchase, as TAA eligibility can vary by contract type.

Q: What is the port speed per SFP+ port?

A: Each of the eight ports runs at 10 Gigabit Ethernet (10GbE) via the SFP+ interface.

Q: What are the physical dimensions of the module?

A: The module weighs 2.75 lb and measures 18.50 x 13.20 x 4.30 inches (L x W x H).

Marty Allison

The 7M17A04000 addresses a specific gap in D2 chassis deployments: when your blade workloads outgrow the default fabric bandwidth and you need dedicated 10GbE SFP+ uplinks without bolting external switches onto the rack. Eight ports in a single EIOM bay is a clean solution if the D2 is your chassis of choice.

Technical Highlights:

• 8-Port SFP+ Density: Eight 10GbE ports in one chassis bay keeps your rack footprint tight — particularly useful in high-density compute rows where switch ports and rack space are both constrained.
• SFP+ Flexibility: The SFP+ standard supports DAC Twinax at short distances (cost-effective for top-of-rack reach under 10m) and optical transceivers for longer structured cabling runs — one module, two deployment patterns.
• Physical Specs: At 2.75 lb and 18.50 x 13.20 x 4.30 in, plan the I/O bay slot allocation before rack build-out — EIOM modules occupy dedicated slots and are not hot-swap interchangeable with other module types in all configurations.

Deployment Considerations:

• Confirm D2 chassis firmware supports this EIOM revision before ordering — Lenovo chassis modules can have firmware dependencies that aren't obvious until installation.
• Transceivers are not included and must be sourced separately; budget and lead time for matched SFP+ optics before committing to this module in a project BOM.

Best fit for enterprise data center or high-density compute environments running ThinkSystem D2 chassis where per-blade 10GbE segmentation is a network architecture requirement — not a general-purpose switch replacement.
