Purpose-built backplane for dense storage
The Dell JXR3K is a 24-bay 2.5-inch SAS/SATA backplane board designed specifically for PowerEdge R920 and R930 servers. It accepts up to 24 drives, letting administrators maximise capacity inside a supported chassis. The board targets IT teams that need to expand or repair storage in these exact Dell platforms without third-party adapters.
Passive thermal profile and power delivery
The backplane contains no active cooling components, so it adds no fan noise and draws negligible power beyond the drives themselves. Heat dissipation relies on the server’s existing airflow design, keeping acoustics unchanged during normal operation. Power distribution follows the host system’s backplane connectors, requiring no separate supply.
OEM construction with Mini-SAS HD links
Built as a genuine Dell OEM part, the board uses Mini-SAS HD connectors to link each drive bay to a compatible RAID controller. The 18 x 8 x 3 inch form factor matches the factory drive cage, ensuring screw holes and guide pins align without modification. At 3.2 lbs it seats securely in the rack, and the SAS/SATA interface supports both drive types for flexible deployment.

Questions about this item
How do I install the JXR3K 24-bay backplane into a PowerEdge R920 or R930, and which step is often missed?
Align the board with the chassis guide pins, press it firmly until the Mini-SAS HD connectors seat fully, then secure the retention screws; the step most often missed is verifying that all Mini-SAS HD cables click into place on both the backplane and the RAID controller.
What maintenance or replacement will the JXR3K backplane need during its service life?
The backplane itself has no moving parts and requires no scheduled replacement; plan to inspect Mini-SAS HD cable connections and drive carrier latches during routine server maintenance, and replace any drive that reports SMART errors.
What limit appears first when the JXR3K backplane runs all 24 bays under sustained heavy I/O?
The practical limit is the aggregate throughput of the Mini-SAS HD links to the RAID controller; once that bandwidth is saturated, drive latency rises even though the backplane supports 24 x 2.5" SAS or SATA drives.
