Lenovo ThinkSystem 1U 4x3.5" SAS/SATA Backplane Option

The Lenovo 4XH7A09907 is a backplane option for ThinkSystem servers that installs in a 1U bay and gives you four drive slots ready for 3.5 inch SAS or SATA media. By adding this kit, you can grow local storage without changing the server footprint or adding extra enclosures.

Because the backplane was engineered for Lenovo hardware, it drops straight into compatible ThinkSystem models, including part numbers 7D2XA019EA and 7D2XA01DEA. Cabling lines up, power connections are already in place, and firmware recognizes the new drives immediately, so administrators can spend more time on workload planning and less time on physical integration.

This option is a practical upgrade for virtualization hosts that need added capacity for virtual machine images, for file and print servers that have started to outgrow their initial disks, or for branch offices that want on-premise storage without expanding the rack. The 1U form factor frees valuable rack space for networking gear or additional compute nodes, which helps data centers and small IT rooms stay organized and efficient.

Whether you run a growing small business or manage a larger environment with several ThinkSystem nodes, this backplane delivers straightforward scalability. It supports both performance-focused SAS drives and cost-effective SATA drives, so you can tailor each slot to the workload and budget. The result is faster provisioning, reduced operational costs, and a server that keeps pace with changing storage demands.
