Intel® RAID Controller RS3MC044

Versatile and Scalable 12Gb/s SAS-3 Intelligent RAID Controller

With computing needs that change frequently and the continuing trend of explosive data growth, businesses need server solutions with highly versatile and scalable storage. The Intel® RAID Controller RS3MC044 provides versatility by allowing for all common RAID levels across both internal and external connectors; plus scalability when teamed with expanders or JBODs. Its high flexibility and broad feature set make it an exceptional choice to address the challenges of today’s datacenter.

The Intel RS3MC044, designed with two 1.2GHz processor cores, 72-bit DDRIII and LSI MegaRAID technology, provides industry-leading benefits such as the ability to support 750K RAID 5 IOPS and 6,000MB/s throughput performance when using high performance 12Gb/s devices. Four internal ports allow for connecting to harddrives or SSDs within the server while an additional four external ports allow for the addition of JBODs to ensure plenty of storage capacity and room to grow.

The Intel RS3MC044 is compatible across a wide range of devices with backward compatibility to previous PCIe and SAS generations through automatic negotiation. This allows for SAS data transfer rates of 12 and 6Gb/s per lane and SATA data transfer rates at 6Gb/s per lane.

The Intel® Web Console 2, provided to manage this adapter, enhances RAID volume creation by empowering administrators to further optimize their storage for application performance and data protection. The intuitive graphical user interface makes it easy to deploy all critical system storage functions and helps eliminate complexity and learning curves. As all Intel RAID solutions are validated across multiple platforms with Intel® server boards, chassis, and systems, when used together they deliver the best combination of built-in performance.

Key Advantages

  • Exceptional data protection. Supports data redundancy using SAS or SATA hard disk drives through mirroring, parity, and double parity (RAID levels 1, 5, and 6), plus striping capability for spans (RAID levels 10, 50, and 60).
  • Excellent performance. A dual core LSI SAS3108 ROC, x8 PCI Express Generation 3 host interface and 1GB of 1866 MHz DDRIII SDRAM provide the performance required for highly scalable storage.
  • Versatility and Scalability up to 240 devices. With both internal and external connectivity and support for multiple premium feature upgrades, this add-in card can be used to architect a wide number of solutions, and is compatible with expanders and JBODs with room to grow.
  • FastPath I/O included. This feature provides a high performance I/O accelerator for SSDs. The technology is designed to dramatically boost transactional application throughput, delivering up to 750,000 I/Os per second (IOPS) in RAID mode.
  • Optional MFBU. The Maintenance Free Backup Unit (MFBU) is built using NAND flash that can retain data for up to ten years. In addition, it provides near instant optimal RAID performance versus traditional Lithium Ion (LiON) battery backup units (BBUs), which are limited to just days of retention and can take up to 8 hours to charge. Furthermore, longer lasting technology allows for a standard 3 year warranty.
  • Optional premium feature upgrades. The RS3MC044 includes a connector for optional hardware-based keys that easily plug in to unlock advanced software algorithms designed to improve performance and enhanced data protection. For instance the SSD Cache upgrade allows for using one or more SSD as a large cache pool for the RAID controller which can significantly improve performance of read-intensive applications, such as file, Web and online transaction processing servers.


  • LSI SAS 3108 I/O processor supporting over 750K IOPs1
  • Embedded 1GB 1866 MHz cache (ECC DDR3 memory) to efficiently store data in transition
  • One internal HD SFF8643 mini-SAS internal connector and one HD SFF8644 x4 mini-SAS external connectors
  • x8 PCI Express connector with support for Generation 3 protocol
  • “Heartbeat” LED for visual verification that the card is functioning properly


This controller card is compatible with any server that includes PCI-E Gen 3 slots.
