Lenovo Avago 430-8E 12Gb/s SATA/SAS PCI Express x8 Host Bus Adapter (HBA) with 2x SFF-8644 External Ports and High-Profile Bracket. P/N: 01KN502.

This is a genuine Lenovo Avago 430-8E 12Gb/s SATA/SAS PCI Express x8 Host Bus Adapter (HBA) (Lenovo P/N: 01KN502; Avago/Broadcom P/N: 03-50013-08003, 50013). Designed to provide high-performance, direct connectivity to external storage, this HBA features two external SFF-8644 ports, each supporting up to four SAS or SATA drives at a blistering 12Gb/s per lane. Its PCIe Gen3 x8 interface ensures ample bandwidth for demanding I/O operations, making it an ideal solution for connecting external SAS/SATA JBODs (Just a Bunch Of Disks), tape drives, or other storage devices to compatible Lenovo servers and workstations. As an HBA, it operates in a non-RAID, "pass-through" mode, allowing the operating system or host software to manage the drives directly, which is crucial for software-defined storage (SDS) and virtualization environments.
