Microchip Adaptec SmartRAID 3254-8i 4GB DDR4 3200MHz PCIe Gen4 x8 SAS/SATA controlador RAID (32548IXS)

Server storage bottlenecks can cripple performance, but the Microchip Adaptec SmartRAID 3254-8i eliminates them with 24 Gb/s SAS-4 throughput and a powerful SmartROC 3200 processor. This low-profile PCIe Gen4 x8 controller delivers enterprise-grade RAID for eight internal SAS/SATA drives, backed by 4GB of DDR4-3200 cache and flash-based protection to keep data safe during power loss.

Who is it for

IT administrators, system integrators, and data center operators who need reliable, high-speed RAID for virtualization, databases, or high-capacity storage servers. It fits standard and low-profile chassis, making it ideal for dense rackmount or tower servers where performance and data integrity are critical.

Main features

• PCIe Gen 4 x8 host interface for up to 16 GT/s per lane, doubling bandwidth over Gen3
• 8 internal ports via two Mini-SAS HD (SFF-8643) connectors, supporting SAS-4 and SATA III drives
• 4GB DDR4-3200 cache with flash-based protection (AFM-700 ready) to prevent data loss on power failure
• RAID levels 0, 1, 1E, 5, 6, 10, 50, 60, and JBOD for flexible storage configurations
• Dynamic Cache Pooling and maxCache 4.0 SSD caching to accelerate hot data
• Secure Boot and Self-Encrypting Drive (SED) support for enhanced security
• Management via Adaptec maxView Storage Manager for remote monitoring and configuration
