Integrated RAID Module RMS25KB0x0 and
RMS25JB0x0
The Intel
®
Integrated RAID Module RMS25KB080, RMS25KB040, RMS25JB080 and
RMS25JB040 are intelligent RAID adapter based on the LSI*SAS2308 PCI* Express-
SAS/SATA I/O Processor chip, providing both a SAS controller and RAID engine. With
four independent ports (RMS25KB040 and RMS25JB040) or eight independent ports
(RMS25KB080 and RMS25JB080) supporting 6Gb/s and 3Gb/s SAS data transfers using
one or two SFF-8087 mini multi-lane connectors, the controllers support enterprise-class
SAS or SATA devices. Drives not configured as part of a RAID array can be configured as
“pass through” drives in Non-RAID mode.
Intel
®
Integrated RAID Module RMS25KB080 and RMS25KB040 are custom low-
profile RAID adapters and the PCI Express* connector fits into an x8 or x16 PCI
Express* slot capable of performance up to 8 Gb/s per lane.
Intel
®
Integrated RAID Module RMS25JB080 and RMS25JB040 are custom board-to-
board PCI Express* 3.0 compliant interface RAID adapters and the PCI Express*
connector fits into a 80 pin connector capable of performance up to 8 GT/s per lane.
The RAID modules are designed to fit various Intel
®
Server Boards and systems. For the

• SATA II Protocol to enable communication with other SATA II devices.
• SATA III Protocol to enable communication with other SATA III devices.
• Serial Management Protocol (SMP) to share topology management information
with expanders.
• Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.
