HP iSCSI solutions brief

Performance, throughput and compatibility of HP 6-Gb/s SAS drives

HP introduced Serial Attached SCSI (SAS) hard disk drives with a 6-Gigabit-per-second (6-Gb/s) interface in the first half of

2009. In conjunction with the newly introduced drive controllers, these drives (Figure 3-1) are the next step in the evolution of

the SCSI standard. As this transition begins, it is important to understand the performance, throughput, and compatibility of this

new technology in relation to the existing 3-Gb/s SAS drives and controllers.

Figure 3-1.HP 6-Gb/s SAS hard disk drive

Throughput and performance for 6-Gb/s SAS drives

The new 6-Gb/s SAS interface doubles the raw communication bandwidth for each point-to-point link between individual SAS

drives and the array controller. As with the previous 3-Gb/s standard, data is sent across the link using 8b/10b encoding for

maximum reliability. The link has a maximum theoretical data throughput of 600 MB/s, although its practical maximum is 10%

less. This compares to a maximum throughput of 300 MB/s for the older 3-Gb/s SAS interface.

In addition to the speed of the interface between the drives and the controller, overall storage subsystem performance is

determined by many factors. The most current SAS drives, including those with the new 6-Gb/s interface, have a maximum

sustained disk I/O of about 160 MB/s. This is the maximum rate at which data can be continuously read off of the drive, and it

is significantly less than the 600-MB/s data bandwidth of a 6-Gb/s SAS interface. It is also less than the 300-MB/s bandwidth
