• 24 internal SAS/SATA ports: A dense 24-port configuration enables direct connections to backplanes or hot-swap drive enclosures, delivering expansive storage capacity within a single low-profile card for space-constrained server trays and blade systems.
• 12 Gbps SAS/SATA performance: Each port leverages the high-speed 12 Gbps signaling to support fast data transfer rates, reducing bottlenecks in RAID arrays and enabling smoother streaming, backups, and virtualization workloads.
• PCIe Gen3 x8 interface: The controller communicates with the host system through a wide x8 PCIe Gen3 bus, providing ample bandwidth for RAID processing, metadata management, and sustained I/O bursts under mixed read/write scenarios.
• MD2 low-profile form factor: Designed for dense server environments, the MD2 form factor fits into compact chassis and blade servers without sacrificing performance or expandability, helping to maximize rack space and energy efficiency.
• Smart Storage stack for reliability and performance: Microchip’s integrated storage software suite delivers heatmaps, health checks, predictive analytics, and streamlined RAID management, enabling robust data protection across RAID levels while optimizing cache behavior and rebuild times.

How to install Microchip Adaptec SmartRAID 3154-24i

• Power down the server and disconnect all power sources before handling components to prevent electrostatic discharge and equipment damage.
• Open the chassis and identify a suitable PCIe x8 slot that aligns with the card’s interface and your motherboard’s I/O layout. Remove any adjacent slot covers if necessary to ensure proper airflow and bracket alignment.
• Insert the 3154-24i into the PCIe slot with gentle, even pressure until the card seats firmly. Secure the card to the chassis with a screw in the bracket to prevent movement during operation.
• Connect the internal SAS/SATA cables from the backplane or drive bays to the ports on the controller, ensuring proper cable routing to avoid obstructing fans or airflow. Use appropriate cables and ensure that drives are recognized when the system powers on.
• Power on the server and boot into the operating system. Install or update the Adaptec Storage Manager (ASM) or the compatible storage management software provided by Microchip to initialize the controller, configure RAID arrays, and monitor health, rebuild status, and cache behavior.
