Integrated RAID Controller SROMBSASMR
(AXXROMBSASMR) Technical Product Specification.
6.1 Product Overview
The Intel
®
Integrated RAID Controller SROMBSASMR supports both enterprise-class serial ATA
(SATA) and serial-attached SCSI (SAS) disk drives, which allows customized solutions for
performance, reliability, system expansion flexibility, and hard drive capacity. It provides such
flexibility and helps lower the total cost of ownership with a standardized server and storage
infrastructure.
This RAID controller is designed with four internal SAS/SATA ports through four individual
connectors and uses a custom board-to-board 50-pin connector to provide x4 PCI Express*
support.
