Intel® RAID Expander Card RES2SV240

The SAS/SATA functionality for the Intel® RAID Expander Card RES2SV240 is contained within the LSI* LSISAS2x24 24-Port Serial Attached SCSI/SATA Expander chip. This expander card has twenty-four independent ports supporting 6Gb/s, 3 Gb/s, or 1.5Gb/s SAS and SATA data transfers using six SFF-8087 mini-SAS connectors. This controller supports 4 inputs and 20 outputs configuration, or 8 inputs and 16 outputs configuration. This expander card is powered either from its standard PCI Express* x4 connector (with only power pins) to get power from motherboard PCI Express slot, or from its RA 4-pin power connector for remote cable power.

The expander card is designed to be compatible with the following Intel® RAID Controllers and Modules:

Intel® Integrated RAID Module RMS2MH080

Intel® RAID Module RMS2AF080 and RMS2AF040

Intel® RAID Module RMS2LL080 and RMS2LL040

Intel® RAID Controller RS2BL080, RS2BL040, and RS2BL080DE

Intel® RAID Controller RS2MB044

Intel® RAID Controller RS2WC080 and RS2WC040

Intel® Integrated RAID Module SROMBSASMR

Note: Additional cable might need to be purchased for some of above adapters to connect.

Additional Intel® RAID Controllers and Modules may be supported. For the most up-to- date list, see the Compatibility section under the link for this Intel® RAID Expander Card at http://support.intel.com/support/motherboards/server/.

The expander card supports the SAS protocol as described in the Serial Attached SCSI Standard, Version 2.0. The card also supports the Serial ATA II (SATA II) protocol defined by the Serial ATA Specification, Version 1.0a and the Serial ATA II: Extension to the Serial ATA Specification, Version 1.1. SATA II is an extension to SATA 1.0a.

Protocol Support

Each port on the expander card supports SAS devices, SATA II devices, or both using SSP, SMP, STP, and SATA II as follows:

Serial SCSI Protocol (SSP) to enable communication with other SAS devices.

SATA II Protocol to enable communication with other SATA II devices.

Serial Management Protocol (SMP) to share topology management information with expanders.

Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.

SAS protocol, described in the Serial Attached SCSI (SAS) Standard, version 2.0

RES2SV240 specifications

The Intel RES2SV240 is a versatile and robust RAID (Redundant Array of Independent Disks) controller designed to enhance storage performance and reliability for enterprise environments. This controller is specifically engineered to support high-performance, high-capacity storage arrays, providing organizations with the means to manage vast amounts of data efficiently.

One of the standout features of the Intel RES2SV240 is its support for up to 24 SATA or SAS drives, offering substantial scalability for data-intensive applications. This capability is particularly beneficial for businesses that require a reliable system for large databases, data warehousing, or cloud storage solutions. The controller operates with the Intel IOP348 processor, ensuring high-speed data processing and low latency, crucial for demanding workloads.

The RES2SV240 supports various RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This flexibility allows IT administrators to choose the appropriate configuration based on their specific performance, redundancy, and data availability requirements. The ability to create diverse RAID configurations helps in optimizing storage management while ensuring critical data remains protected against disk failures.

Another notable characteristic of the Intel RES2SV240 is its advanced error-checking capabilities. The controller utilizes features such as CRC (Cyclic Redundancy Check) and ECC (Error-Correcting Code) to ensure data integrity, significantly reducing the risk of corruption during transactions. This reliability is essential in enterprise environments where data accuracy is paramount.

Additionally, the RES2SV240 supports hot-swappable drives, allowing users to replace failed drives without taking the system offline. This feature minimizes downtime and enhances overall system reliability. For further optimized performance, the controller includes a battery-backed write cache, which safeguards data in the event of power loss, ensuring that no transactions or information are lost.

The Intel RES2SV240 is compatible with various server operating systems, making it a flexible solution for different environments. Its management interface is user-friendly and comprehensive, providing detailed insight into storage health and performance metrics, allowing IT personnel to optimize operations effectively.

In summary, the Intel RES2SV240 RAID controller is a powerful tool for businesses seeking to enhance their data storage capabilities. With its support for a large number of drives, versatile RAID configurations, strong data protection mechanisms, and ease of management, it stands out as a reliable choice for enterprise-level storage solutions. Its robust performance characteristics make it a valuable addition to any data-driven organization.
