Intel® RAID Performance 12Gb/s SAS RAID Controllers White Paper 1 Introduction The Intel® 12Gb/s SAS RAID controllers, featuring the LSI dual-core SAS3108 RAID-on-Chip (ROC) processor, offer significant performance enhancements for solutions architected with 12Gb/s or 6Gb/s SAS drives.
Intel® RAID Performance 12Gb/s SAS RAID Controllers White Paper 2 Performance Tests and Results Using IOMeter 1.1, an open-source I/O workload generator, Intel designed I/O workload profiles to demonstrate how real-world applications might perform. Sequential read and write benchmarks reveal how well streaming applications perform.
Intel® RAID Performance 12Gb/s SAS RAID Controllers White Paper Figure 1 Intel Integrated RAID Module RMS3CC080 Large Streaming Reads and Writes Streaming workloads represent contiguous requests made to the disk. The workloads are predominately sequential I/O. Applications such as data warehousing, ETL, and VTL backup operations experience this type of workload for reads.

Intel® RAID Performance 12Gb/s SAS RAID Controllers White Paper 2.2 Transaction-Oriented Applications Applications dominated by random I/O access patterns are well-suited for both SAS hard drives and SSDs. These applications include traditional and transaction capable NewSQL or NoSQL databases. Enterprise database workloads include transaction-oriented queries such as OLTP and OLAP against structured data.
Intel® RAID Performance 12Gb/s SAS RAID Controllers White Paper Figure 4 Intel Integrated RAID Module RMS3CC080 12Gb/s SAS SSD, Transactional Workloads The Intel 12Gb/s SAS RAID controller exhibits incredibly high performance, easily achieving more than 500,000 8-KB random reads - nearly 4,000 MBps. This translates to more than 100,000 database operations for a typical RAID 10 configuration, and even a more capacity-optimized RAID 5 configuration can still achieve upwards of 70,000 database type IOPs. 2.
