Product information

Description

The MICROCHIP SmartRAID 3151-4i RAID Controller is a professional storage management solution designed to provide reliable data protection and high-speed performance for servers and enterprise systems. Utilizing a PCI Express x8 3.0 host interface, this controller connects efficiently to SAS storage drives while delivering a fast 12 Gbit/s data transfer rate. Equipped with 1024 MB of internal memory, it ensures smooth handling of demanding transactional and database workloads. The compact low-profile form factor allows it to fit seamlessly into half-height server chassis, making it a versatile choice for modern data centers and professional IT environments.

Advantages

This RAID controller delivers exceptional read and write performance, supported by advanced caching technologies and a 12 Gbit/s data transfer rate that maximizes bandwidth for heavy workloads. It provides comprehensive data protection through a wide range of supported RAID levels and features integrated flash-based cache protection for enhanced security against power loss. The inclusion of mixed-mode support allows simultaneous use of RAID and HBA devices, while built-in adapter power management reduces overall energy consumption. Additionally, the intuitive web-based interface simplifies configuration, local and remote monitoring, and ongoing storage management tasks.

Suitable for

  • Managing SAS storage drives in enterprise servers
  • Accelerating transactional and database applications
  • Implementing reliable hardware RAID levels 0, 1, 5, 6, 10, 50, and 60
  • Optimizing storage performance with internal cache memory
  • Deploying in half-height low-profile server enclosures

This controller may not be suitable for systems that rely exclusively on SATA drives without a SAS backend, or for standard consumer desktop computers lacking compatible PCI Express x8 expansion slots and low-profile physical clearance.

Key specifications

  • Supported storage drive interfaces: SAS
  • Host interface: PCI Express x8 3.0
  • RAID levels: 0, 1, 5, 6, 10, 50, 60
  • Data transfer rate: 12 Gbit/s
  • Internal memory: 1024 MB
  • Form factor: Half-height, low-profile
  • Width: 167 mm
  • Height: 64 mm

To use the MICROCHIP SmartRAID 3151-4i RAID Controller, install the hardware into an available PCI Express x8 slot within a compatible server chassis and securely connect your SAS storage drives to the controller ports. Ensure the system power is completely disconnected before installation. Once physical installation is complete, power on the system and access the controller configuration utility or the web-based management interface to set up your desired RAID arrays, configure caching options, and monitor drive health. Install any necessary drivers and management software within your operating system to maintain optimal performance and receive status alerts.

What to consider before purchase

  • Verify compatibility with your server motherboard and available PCI Express x8 slots
  • Confirm that your storage infrastructure utilizes SAS drives
  • Check the physical dimensions to ensure the low-profile form factor fits your chassis
  • Assess your application requirements to determine if the supported RAID levels meet your data protection needs
Usage recommendations: Regularly monitor the controller status and cache protection health using the management software, keep the firmware up to date, and ensure adequate airflow within the server chassis to maintain optimal operating temperatures for reliable long-term performance.
