The 6GB/s LSI MegaRAID SATA+SAS controller cards, featuring the LSISAS2108 SAS RAID-on-Chip (ROC), are designed to double the data transfer rates of their 3Gb/s predecessors to deliver industry-leading performance of nearly 3GB/s for streaming read & write operations. This superior read/write performance makes them well suited for a broad range of application workloads, from compute-intensive data center applications such as email, OLTP, and database to storage and content applications such as streaming video, and data archival.
- Existing systems using SATA and SAS hard drives
- End-to-end 6Gb/s SAS ecosystems
- Solid-State Drive (SSD) environments
- Throughput-intensive streaming applications
- Transaction-oriented server and database applications
- Streaming read
Streaming read workloads represent contiguous read requests made to the disk. They are predominately sequential I/O and are typically seen in applications such as media servers or Virtual Tape Libraries (VTL).
- Streaming write
Streaming write workloads represent contiguous write requests made to the disk. They are predominately sequential I/O and are typically seen in applications such as media capture, VTL, and archival/backup.
- Web server
Web server workloads typically service multiple, predominately random simultaneous requests.
- OS drive
OS drive workloads represent the I/O activity of an operating system drive. They are handling random I/O with a read/write ratio of 70:30.
- File server
File server workloads represent a large number of users requesting access to unstructured reference data and files. They are handling random read/write requests with a ratio of 80:20.
- Email server
Email server workloads typically service multiple simultaneous requests to transport or store email. They are handling a fairly even mix of random reads and random writes.
OLTP workloads represent transaction processing and database query I/O requests that require a read of the original value, followed by an update, write and verify operation. They handle predominately random requests with two reads for every write.
