Built on the proven 5th generation SmartROC 3200 storage controller, this PCIe Gen 4 RAID adapter delivers tri-mode SAS/SATA/NVMe functionality that empowers server OEMs, storage system integrators, and enterprise deployments to consolidate workloads with a single, powerful host adapter. Whether you’re optimizing a dense server chassis, expanding back-end storage, or provisioning a mission-critical array, the Adaptec 3204-8i gives you the bandwidth, features, and management capabilities to meet today’s demanding IO profiles while accommodating future growth.

• Tri-mode flexibility: Seamlessly connect SAS, SATA, and NVMe drives on a single adapter, enabling mixed storage environments and future-ready upgrade paths without swapping hardware. This tri-mode capability simplifies cabling, backplane design, and storage topology while keeping performance consistently high across drive types.
• PCIe Gen 4 x8 host interface: Harness the full power of PCIe Gen 4 with an x8 host connection, delivering higher aggregate bandwidth and lower latency to support virtualization, databases, AI workloads, and other IO-intensive applications in modern data centers.
• Eight internal ports (8i) for dense arrays: Eight internal ports provide scalable connectivity to backplanes or JBOD enclosures, enabling compact server configurations or larger, multi-disk RAID arrays while maintaining streamlined cabling and straightforward RAID management.
• SmartRAID 3204-8i controller core: Powered by Microchip’s robust SmartROC 3200 family, the controller combines a high-performance RAID engine with proactive error detection, fast rebuilds, and resilient data protection to minimize downtime and maximize data integrity during drive failures or rebuild operations.
• Enterprise-grade features and management: Supports a comprehensive set of RAID levels (0, 1, 5, 6, 10, 50, 60), write-back caching, and fast rebuilds, with centralized monitoring, firmware updates, and configuration via Adaptec Storage Manager. Designed for reliability in 24/7 data center workloads and OEM deployments.

How to install Microchip Adaptec 24G SAS/SATA/NVMe PCIe Gen 4 RAID Adapter

• Power down the host server and disconnect all power sources to ensure safe handling of components.
• Open the chassis and identify an available PCIe Gen 4 x8 slot that meets the server’s expansion guidelines.
• Remove the slot cover as needed and insert the Adaptec 3204-8i RAID adapter firmly into the PCIe slot. Ensure the card seats completely and screw it to the chassis bracket for stability.
• Connect the appropriate drive backplanes or SAS/SATA/NVMe cabling to the eight internal ports on the RAID adapter, following the server’s backplane wiring plan and the enclosure’s documentation to prevent misalignment.
• Reinstall the chassis cover, reconnect power, and boot the server. Enter the system BIOS/UEFI if required to verify the card is detected and the port mappings are correct.
• Install or update the Adaptec Storage Manager software and drivers from Microchip’s official resources. Use ASM to initialize the card, configure RAID arrays, and apply the recommended cache settings for your workload.
• Configure the desired RAID levels, stripe sizes, write caches, and hot-spare policies. Run a verification or consistency check on newly created arrays to ensure data integrity before placing them into production use.
• Plan a firmware update strategy. Keep the adapter’s firmware current to ensure compatibility with NVMe drives, backplanes, and newer OS versions. Document the configuration for future reference and disaster recovery planning.

Frequently asked questions

• Q: What types of drives does the Adaptec 3204-8i support in tri-mode?
  A: It supports SAS, SATA, and NVMe drives through compatible backplanes and enclosures, enabling mixed-drive configurations in a single RAID solution.
