Intel RAID Controller RS2SG244

24-port internal and 4-port external SAS-2 RAID controller for scalable performance applications

Intel® RAID Controller RS2SG244

Key features

  • LSI SAS2108* ROC controller providing SAS 2.0 compliance, including 6-Gb/s data transfer
  • Embedded 512-MB 800 MHz cache (ECC DDR2 memory) to efficiently store data in transition
  • 24 internal ports with 6 SFF8087 (Mini-SAS) connectors
  • Four external ports with a single SFF8088 connector
  • Speaker to deliver audible alerts
  • x8 PCI Express* Gen 2 interface for fast communication with the server board
  • Six internal cables with SFF8087 connectors on each end
  • Optional: Intel® RAID Smart Battery AXXRSBBU7 for up to 72 hours of cache data retention

Scalable and affordable solution for growing storage requirements

The Intel® RAID Controller RS2SG244, powered by LSI MegaRAID* Technology, has 24 internal and 4 external ports and supports both internal drive storage and external JBOD expansion for up to 240 SATA or SAS drives. With a large number of internal ports, the Intel RAID Controller RS2SG244 connects up to 24 drives inside the server via direct connection or passive backplane. Using the external SAS ports, multiple JBODs can be connected to a server, providing a scalable and affordable solution for growing storage requirements. The RS2SG244 supports data transer rates of up to 6-Gb/s per port, and brings new featues and improved perfomance regardless of whether the storage solution utilizes 3-Gb/s or 6-Gb/s SAS or SATA drives.

Target applications

Scalable 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, Highly scalable

LSI* SAS2108 ROC technology, x8 PCI Express* 2 host interface, and 800-MHz cache enhances the performance of mainstream applications. Capable of connecting up to 28 drives directly or up to 240 using SAS expanders.

Easy to use management utility

The Intel® RAID Web Console provides the essential software interface to efficiently manage Intel® RAID products, whether deployed in an enterprise or small business. Intel also offers a collection of applications and tools including a pre-boot setup utility and a full spectrum of online Intel RAID management utilities.

Outstanding availability

Delivers proactive drive monitoring and automatic error correction. An optional battery backup maintains the integrity of data in transit to drives in the event of a power interruption.

Support for premium feature upgrades

Includes a connector for optional hardware-based keys that easily plugs in to unlock advanced software algorithms designed to improve performance and enhanced data protection. For instance, the Intel® Solid-State Drive (Intel® SSD) Cache with FastPath* I/O upgrade allows for using one or more Intel® SSD as enhanced cache for the Intel® RAID Controller, which can significantly improve performance of read-intensive applications, such as file, Web, and online transaction processing servers.
