Lenovo 7M27A03915 Thinksystem SATA Hdd/ssd Backplane for SN550

Lenovo 7M27A03915 ThinkSystem SATA HDD/SSD Backplane for SN550

Overview

The Lenovo 7M27A03915 is a SATA HDD/SSD backplane designed specifically for the ThinkSystem SN550 blade server. If you are expanding or replacing storage connectivity in an SN550 chassis, this is the purpose-built backplane that slots into Lenovo's blade infrastructure — no adapter improvisation, no compatibility guesswork. At 0.40 lb and measuring 9.50 x 6.00 x 2.25 in, it is compact enough to fit within the blade's dense form factor without adding meaningful weight to your chassis load. Manufactured in Mexico, it ships as a factory-new, genuine Lenovo component sourced through US distribution channels.

Key Features

• SATA Interface: SATA connectivity means compatibility with a wide range of enterprise HDDs and SSDs available for the SN550 platform — giving you flexibility in storage selection without needing SAS-only drives, which often carry a cost premium for equivalent capacity.
• SN550-Specific Design: This backplane is engineered for the ThinkSystem SN550 blade server. Installing a backplane that is not platform-matched risks mechanical misalignment or electrical incompatibility; the 7M27A03915 removes that risk entirely for SN550 deployments.
• Compact Form Factor (9.50 x 6.00 x 2.25 in): The backplane's dimensions are matched to the SN550 blade envelope. There is no cutting or bracket modification required — it is a direct mechanical fit for the target platform.
• Low Component Weight (0.40 lb): At under half a pound, this backplane contributes negligible incremental weight to your blade chassis, which matters when you are managing per-chassis weight limits in high-density rack installations.
• Factory-New Genuine Component: Sourced directly through US authorized distribution — no grey-market risk, no parallel-import uncertainty. For warranty and support continuity on production blade infrastructure, provenance matters.

Integration and Compatibility

The 7M27A03915 is confirmed for use with the Lenovo ThinkSystem SN550 blade server platform. If you are building out or servicing SN550 nodes in a multi-chassis data center infrastructure, this backplane is the correct field-replacement or expansion component. Confirm your SN550 firmware and chassis revision against Lenovo's compatibility matrix before ordering if your SN550 units are running non-current firmware — backplane compatibility is typically stable across SN550 revisions, but verifying against your server component service documentation eliminates risk on production systems. Pair with appropriate SATA storage drives validated for the SN550 platform to complete your storage sub-assembly.

Frequently Asked Questions

Q: What server platform is the 7M27A03915 designed for?

A: The 7M27A03915 is designed specifically for the Lenovo ThinkSystem SN550 blade server. It is not a universal backplane and should only be installed in SN550 nodes.

Q: What storage interface does the 7M27A03915 support?

A: The backplane uses a SATA interface, supporting SATA HDDs and SSDs compatible with the SN550 platform.

Q: What are the physical dimensions and weight of this backplane?

A: The 7M27A03915 measures 9.50 x 6.00 x 2.25 inches and weighs 0.40 lb.

Q: Where is the 7M27A03915 manufactured?

A: It is manufactured in Mexico and sold as a factory-new, genuine Lenovo component through US distribution.

Q: Can this backplane be used with SAS drives?

A: No. The 7M27A03915 uses a SATA interface. SAS drives are not compatible with this backplane. Use SATA HDDs or SSDs validated for the SN550 platform.

Eden Phillips

When you are servicing or expanding storage in an SN550 blade node, the 7M27A03915 is the correct platform-specific SATA backplane — not a workaround, not an adapted part. Its 9.50 x 6.00 x 2.25 in footprint is matched to the SN550 blade envelope, which means installation is a direct mechanical fit rather than a bracket-and-hope exercise you sometimes encounter with generic aftermarket components.

Technical Highlights:

• SATA Interface: SATA gives you access to a broader range of cost-effective enterprise drives compared to SAS-only backplanes — relevant if you are balancing storage density against per-node budget in a multi-blade deployment.
• Platform-Matched Dimensions (9.50 x 6.00 x 2.25 in): Designed to fit the SN550 chassis without modification — reduces installation time and eliminates mechanical risk during field replacement.
• 0.40 lb Component Weight: Negligible chassis weight impact, which matters when you are near blade chassis weight limits in high-density rack configurations.

Deployment Considerations:

• Verify your SN550 firmware revision against Lenovo's compatibility documentation before installing — while backplane compatibility is generally stable across SN550 revisions, confirming against current service documentation is standard practice on production blades.
• This backplane supports SATA only — do not attempt to install SAS drives. If your workload requires SAS performance characteristics, you will need a different backplane option for the SN550 platform.

The 7M27A03915 is the right call for SN550 infrastructure teams replacing a failed backplane or adding SATA storage capacity in a blade environment where platform-matched, genuine components are non-negotiable for support continuity.
