Intel 8 Port SAS Controller

The Intel RS25GB008 is a host bus adapter that brings eight external SAS or SATA ports to any server, storage enclosure, or high-end workstation that relies on fast, direct connections to multiple drives. By linking through a PCIe x8 Gen3 slot and allowing up to 6 Gb/s on every port, it helps large databases, virtualization clusters, or media workflows move data without becoming the bottleneck.

Expansion is straightforward. With support for as many as 1,024 devices when used with SAS expanders, the card can sit at the heart of a growing JBOD shelf or a complete software-defined storage pool. Each drive remains visible to the operating system, so administrators using ZFS, Windows Storage Spaces, or similar tools get the disk-level access they need.

At its core is the LSI2308 IO processor, a chipset trusted in enterprise environments for steady throughput and low CPU overhead. Because the card handles basic bus management, host resources stay free for the workloads that actually matter.

Installation is simple. Intel includes full-height and low-profile brackets in the box, so the adapter fits 1U, 2U, or tower cases with equal ease. A quick start guide walks through slot placement and driver installation. You supply standard mini-SAS cables, pick the operating system of choice—Windows, Linux, Nexenta, or VMware—and power up.

Whether you are expanding a data center with new disk shelves, building a lab cluster that needs individual drive control, or outfitting a post-production suite with high-capacity JBOD arrays, the RS25GB008 delivers clean, reliable connectivity that scales with your storage plan.
