Broadcom 9440-8i PCIe 8 Port SAS SATA RAID Controller

Broadcom 9440-8i MegaRAID Tri-Mode Storage Adapter is an 8-port PCIe RAID controller that enables high‑performance storage arrays for SAS, SATA, and NVMe drives in a single card. Built around the SAS3408 ROC, it delivers 12 Gb/s per port across eight internal SAS/SATA channels via SFF-8643 connections and supports NVMe, SAS, and SATA devices through Tri‑Mode SerDes, allowing NVMe PCIe SSDs to participate in a MegaRAID array alongside SAS/SATA disks. The card is a PCIe Gen 3.1 x8 device and is commonly sold as Dell part 0YW3J6 (also known as 9440-8i), making it suitable for Dell servers and other platforms that require scalable internal storage expansion. It supports up to 32 virtual drives and up to 63 SAS/SATA devices (with up to 2 NVMe devices), features a 64 KB stripe size for most arrays, and includes MegaRAID data‑protection capabilities such as online capacity expansion and online RAID level migration where supported. Compatible with major operating systems—including Windows, VMware vSphere/ESXi, and popular Linux distributions—the Broadcom 9440‑8i is positioned for dense, reliability‑driven storage implementations in data centers, server blades, and enterprise workloads.
