Also listed as: 01GU572, 01GU573, 7Y37A01091-01, Broadcom SAS3416, 430-16e, AUNM · made by Broadcom
The Lenovo ThinkSystem 430-16e SAS/SATA 12Gb HBA is a high-density external storage controller card based on the Broadcom SAS3416 I/O controller chip. Delivering 16 lanes of external 12Gb/s SAS and 6Gb/s SATA connectivity through four Mini-SAS HD (SFF-8644) ports on a PCIe 3.0 x8 host bus, it connects ThinkSystem servers directly to external SAS JBOD expansion enclosures (such as the D1212 and D1224) and external LTO tape autoloaders. In the secondary hardware market, it is popular for software-defined storage architectures like TrueNAS Core, Ceph, and Windows Storage Spaces. Used buyers should ensure the card carries Lenovo OEM firmware for UEFI management integration and includes the correct PCIe bracket height.

About the 7Y37A01091
7Y37A01091 is an enhanced variant of Lenovo's 8-port internal 12Gb/s SAS/SATA hardware RAID controller for ThinkSystem servers, powered by the Broadcom SAS3108 RoC. Upgraded with 2GB of onboard cache and integrated flash-backed write cache protection, it supports RAID 0, 1, 5, 6, 10, 50, and 60. It filled an important role in Lenovo's V1 generation by providing enterprise RAID 6 protection and zero-maintenance cache preservation at a lower price point than the RAID 930 series.
Compatibility
The adapter is compatible with ThinkSystem V1 server models including SR650, SR630, SR550, SR590, and ST550. It installs into a PCIe 3.0 x8 slot and uses two internal Mini-SAS HD (SFF-8643) ports for drive cage cabling. It does not support SlimSAS backplane cabling or NVMe drives. Unlike the 1GB version, the 2GB flash model supports RAID 6 dual-parity arrays and maintains write-back caching securely during abrupt power loss.
How to identify a genuine unit
Genuine Lenovo boards feature a label indicating option part number 7Y37A01091, FRU part number 01KN503 or 01KN504, and feature code AUNR. In the UEFI human interface infrastructure (HII) and XClarity Controller, the card reports as ThinkSystem RAID 730-8i 2GB Flash. Unofficial LSI clones will lack Lenovo subsystem identification.
Buying used
Confirm that the integrated flash backup module is present on the board and reports healthy status in StorCLI. Inspect the two Mini-SAS HD ports and the PCIe edge card for wear or corrosion. Ensure the card is supplied with the correct PCIe bracket height for your server chassis. Verify that the controller accepts standard Lenovo firmware updates.
