Pros & Cons
👍 Pros
- Genuine Lenovo FRU ensures exact dimensional compatibility with the hot-swap backplane connector and bay latch mechanism on RD-series servers.
- Hot-swap design allows drive installation and replacement without powering down the server, minimizing service interruption.
- Tool-free latch mechanism speeds up drive swaps during maintenance windows when multiple bays need servicing.
- Accepts both SAS and SATA 3.5" drives, maintaining flexibility for different storage tiers within the same chassis.
👎 Cons
- Compatibility is limited to four Lenovo ThinkServer RD models — this caddy will not fit other Lenovo server lines or third-party chassis.
- Does not accommodate 2.5" drives natively, requiring a separate adapter bracket that may introduce fitment inconsistencies.
- As a single-caddy purchase, populating an entire server chassis becomes expensive compared to aftermarket multi-packs.
- The plastic latch component is the most failure-prone element and cannot be sourced or replaced independently.
Frequently Asked Questions
Which Lenovo servers does this caddy fit?
It is compatible with the Lenovo ThinkServer RD650, RD550, RD450, and RD350 — specifically the chassis configurations with 3.5" hot-swap drive bays. It will not fit servers configured with 2.5" bays, even within these same model lines.
Can I use a 2.5" drive in this caddy with a bracket adapter?
The caddy is dimensioned for 3.5" drives. While some users install 2.5" drives using third-party 2.5-to-3.5" adapters, this is not the intended configuration and may not align with the screw mounting points. For 2.5" drives, Lenovo offers dedicated 2.5" caddies for these servers.
Is this an OEM Lenovo part or a third-party compatible?
This is a genuine Lenovo part with FRU number 03T8898 and part number SM10A43752. It matches the original caddy shipped with the RD-series servers, ensuring correct fit, latch engagement, and backplane alignment.
Does the caddy include screws for mounting the drive?
Yes, caddy trays of this type typically include the mounting screws needed to secure a 3.5" hard drive to the tray. Verify screw count upon receipt to ensure nothing was missed in packaging.
Will this work with SSDs or only mechanical hard drives?
It accepts any 3.5" form factor drive — both mechanical HDDs and 3.5" SATA or SAS SSDs. The caddy is a physical carrier and does not affect drive interface compatibility, which is determined by the server's backplane.
