About the 4Y37A09724
The Lenovo 4Y37A09724 is a high-bandwidth 16-port external 12Gb SAS/SATA Host Bus Adapter designed for modern PCIe Gen4 platforms. Powered by the Broadcom SAS3816 IOC and operating across a PCIe 4.0 x8 host bus interface, it delivers direct non-RAID host connectivity to massive external storage shelves such as the Lenovo Storage D3284 and D1224. It effectively doubles host-side PCIe bandwidth compared to legacy Gen3 HBAs.
Compatibility
Compatible with Lenovo ThinkSystem SR650 V2, SR630 V2, SR650 V3, SR630 V3, SR645, and SR665 systems. It features four external Mini-SAS HD (SFF-8644) ports mounted on its rear bracket. It operates strictly in non-RAID IT mode and is optimized for Software-Defined Storage, database backups, and high-density tape automation environments.
How to identify a genuine unit
Recognizable by the Lenovo manufacturing label listing option code 4Y37A09724, FRU part number 01PE812, and feature code B8MH. Four external SFF-8644 ports with secure metal latching mechanisms populate the rear I/O plate. Management consoles identify the board as ThinkSystem 440-16e SAS/SATA PCIe Gen4 12Gb HBA.
Buying used
When evaluating a pre-owned 440-16e adapter, inspect all four external SFF-8644 connectors for debris or misaligned pins. Verify that the PCIe bracket matches your target rack server chassis height. Ensure the board is recognized cleanly in system UEFI and initializes with native Broadcom mpt3sas device drivers under Linux or Windows Server.
