## Long description

Microsemi SmartRAID 3151-4i is a hardware RAID controller designed for servers and workstations that require high-throughput, low-latency storage. The card uses a PCI Express x8 Gen3 host interface and supports drive data rates up to 12 Gbit/s for SAS and SATA III devices. It implements RAID levels 0, 1, 1 ADM, 5, 6, 10, 50 and 60, and is delivered in an MD2 half-height PCIe form factor (167 × 64 mm). The adapter includes integrated flash-based cache protection and supports SSD caching and write-back/read caching to accelerate transactional and database workloads.
Advantages
The SmartRAID 3151-4i provides high I/O performance and caching features that increase read/write bandwidth and IOPS when used with 12 Gbit/s drives. Integrated flash-based cache protection eliminates the need for battery backup while ensuring cached data is protected during power loss. The adapter supports mixed-mode operation to handle RAID arrays and HBA devices simultaneously and includes power management features to reduce overall adapter power consumption.
Suitable for
 Database servers requiring high transactional IOPS and low latency
 Virtualization hosts where multiple VMs demand sustained storage performance
 Storage arrays combining SAS/SATA drives and SSD caching for mixed workloads
 Server or workstation upgrades that need reliable RAID migration and management
Key specifications
 Host interface: PCI Express x8 Gen3
 Drive interface/data rate: SAS and SATA III up to 12 Gbit/s
 Supported RAID levels: 0, 1, 1 ADM, 5, 6, 10, 50, 60
 Form factor: MD2, half-height PCIe card (167 × 64 mm)
 Integrated flash-based cache protection with capacitor-backed mechanism
 Supports SSD caching with read and write-back caching modes
 Compatibility: Windows 7/8/10 and Windows Server 2008/2012/2016 x64
How to use
Install the SmartRAID 3151-4i into a free PCIe x8 (or x16) slot in a compatible server or workstation following the system manufacturer's guidelines. Connect SAS/SATA drives to the adapter using appropriate cables or backplane connectors. Configure RAID arrays and caching policies using Microsemi's management tools; the adapter supports the maxView HTML5-based interface for local and remote configuration and monitoring. Ensure the adapter's flash-based cache protection module is properly seated and monitored through firmware utilities so cached data can be backed up to flash in case of power loss.
Usage recommendations
For best performance, pair the controller with 12 Gbit/s SSDs when low latency and high IOPS are required, and enable SSD caching (read and write-back) for transactional workloads. Keep firmware and management software updated and monitor cache protection status regularly. When migrating arrays or replacing drives, use the adapter's migration and data management features to minimize downtime and preserve data integrity.
