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-todate list, see the Compatibility section under the link for this Intel® RAID Expander Card at http://www.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 2 Intel® RAID Expander Card RES2SV240 Hardware User's Guide
