Lenovo 7M27A03918 Thinksystem RAID 530-4I 2 Drive Adapter KIT for SN550

Lenovo 7M27A03918 ThinkSystem RAID 530-4i 2-Drive Adapter Kit

Overview

The Lenovo 7M27A03918 is a factory-configured adapter kit that adds two additional drive bays to a Lenovo ThinkSystem SN550 blade server equipped with a RAID 530-4i controller. Rather than swapping the entire storage subsystem, this kit extends the drive count within the existing RAID 530-4i topology — a practical fit for deployments that need incremental storage expansion without a full hardware refresh or controller replacement. If you are running a RAID 530-4i in your SN550 and need two more drives attached to that controller, this is the direct path.

Compatibility

Designed specifically for the ThinkSystem SN550 blade server. Works in conjunction with the RAID 530-4i (4-port internal) controller already installed in that chassis. This kit does not apply to other SN-series blades, SR-series rack servers, or ST-series towers — the SN550's blade form factor and internal bay architecture are what drive the fit. Verify your SN550's current controller configuration before ordering: the RAID 530-4i must already be present; this adapter kit does not include or replace the controller itself.

Installation Notes

Packaged as a kit for field installation into the SN550 chassis. The unit ships at 0.85 lb and measures 6.00 × 10.00 × 4.00 in — sized to fit the SN550 internal bay envelope. Installation is performed at the blade level; the SN550 must be removed from the blade chassis before drive adapter work. Consult the ThinkSystem SN550 server maintenance manual for slot assignment and torque specifications. Country of origin is Mexico (MX); UNSPSC code 43201500 (computer storage devices and accessories).
