Product Features
Technical Overview
This adapter employs a 12Gb/s SAS controller that maximizes data transfer rates for both SAS and SATA drives. The PCIe 3.0 x8 host interface ensures minimal bottlenecking, allowing the card to fully utilize available bandwidth for storage operations. With 2GB of flash-backed cache, it provides non-volatile memory protection, safeguarding data in transit against unexpected power loss.
The card includes eight internal SAS ports via two SlimSAS x4 connectors (SFF-8654), enabling direct attachment to drive backplanes. It supports intermixing of 12Gb/s and 6Gb/s drives, though mixing SAS and SATA drives within the same array is not permitted. The plug-in card form factor measures 2.50" in height and 6.60" in length, conforming to standard PCIe slot dimensions for broad server compatibility.
Relevant factors for this section include Host Interface, Controller Type, RAID Supported, Cache Memory. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.

Deployment / Use Cases
This adapter is engineered for server storage expansion and data protection scenarios. It is ideal for IT departments upgrading existing servers with additional drive bays or implementing new storage arrays that require hardware RAID acceleration.
Common deployments include database servers needing RAID 10 for high I/O performance, file servers utilizing RAID 6 for capacity and dual-disk fault tolerance, and backup targets configured in JBOD mode for maximum storage utilization. The card's compatibility with both SAS and SATA drives allows cost-effective mixing of SSD and HDD technologies within the same system, though not within individual arrays.
Server Storage Expansion
Adds eight internal ports to servers with available PCIe 3.0 x8 slots, enabling connection to additional drive backplanes or direct-attach storage enclosures.
Hardware RAID Acceleration
Offloads RAID computations from the host CPU, improving system performance for demanding applications like virtualization, video editing, or scientific computing.
Physical Profile
The adapter is a plug-in card with a low-profile design that fits standard PCIe slots. Its dimensions of 2.50" (63.50 mm) in height and 6.60" (167.64 mm) in length ensure compatibility with most server chassis. The form factor is optimized for broad server integration without consuming excessive space.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 2.50" (63.50 mm). This helps confirm rack, shelf, desk, or cabinet fit before installation.
