Lenovo ThinkSystem RAID 5350-8i PCIe 12Gb Adapter

The Lenovo 4Y37A72482 is a RAID adapter made for administrators who want straightforward, reliable storage management in a ThinkSystem server. By fitting into a PCIe 3.0 x8 slot, it delivers the bandwidth required to keep up with modern workloads while avoiding the cost and complexity of add-on cache. The card connects through a Mini SAS HD SFF-8643 interface, letting you run either high-speed 12 Gb/s SAS drives or more economical 6 Gbps SATA drives without changing hardware.

Supported RAID levels include 0, 1, 10, and 5, so you can prioritize raw performance, mirroring, or parity protection based on each project. This flexibility makes the adapter useful in a range of environments: a small business that needs simple file redundancy, a branch office running virtual machines on VMware, or a lab that wants to stripe drives for maximum throughput under Linux. Because Lenovo validates the card with Windows Server, popular Linux distributions, and VMware, you can move between operating systems or run mixed-OS estates with confidence.

The cacheless design keeps costs down and removes battery maintenance from your to-do list, which is helpful for organizations that prefer a set-and-forget approach. Its compact circuit board, measuring about 2.5 inches by 6.6 inches, leaves room for additional adapters in dense chassis. Installation is as simple as seating the card, attaching your internal SAS cables, and configuring the desired RAID level through Lenovo XClarity or the server’s UEFI BIOS.

If you need an affordable path to RAID on a ThinkSystem platform without sacrificing compatibility or everyday performance, this adapter fits neatly into that role.
