6Gbps SAS drives for G6 servers

With double the data rate of traditional 3Gb/s SAS drives, the new 6Gb/s SAS drives bring you an opportunity to break through the system bottlenecks of the past.  Ramping up to 6Gb/s means greater system bandwidth than before. 


 


Speaking of data rate, let's quickly dispel the confusion between 'data rate' and 'RPM.'  Data rate or line rate is the speed at which data travels from the disk to the HBA or storage controller; while RPM is the rotational speed of the drive platters (in rotations per minute).  One more thing - data transfer speed is not influenced by access time or latency.


 


On March 30, HP introduced the 146/300GB 6G SAS 10K 2.5in DP ENT drives (the first two 6G SAS drives) to the portfolio.  If you have HP DL360 G6, DL380 G5, or BL460c G6 servers in your environment, it's easy to take full advantage of these high-performing, dual port 6Gb/s SAS drives.


 


Note that for a storage subsystem to truly operate at 6Gb/s, the drive, the HBA or storage controller, and the server backplane must have 6Gb/s data transfer rates, or the system will negotiate down to an acceptable level for all components.  Refer to teh server and HBA/controller technical specifications for transfer rate details.
