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.
Have you been waiting for higher capacities on your 2.5-inch small form factor (SFF) drives? HP will launch the 300GB 3G SAS 10K SFF Enterprise Drive shortly. With this drive you will get more for less:
- More storage capacity than any other SFF drive in the market
- 50% less power usage in 70% less space than 3.5-inch 15K drives.
This drive is an enterprise drive, ideally suited for those environments for servers and storage solutions running business critical, high I/O and heavy workload applications. They provide the high performance and maximum reliability (about 3.5 times that of Entry Drives) required by
- Near 24/7 operating environments
- Large databases
- High-transaction applications such as e-mail, ERP, and CRM
- Real-time customer facing environments
Being the leader in the industry when it comes to small form factor SAS drives, HP is known to ship more small form factor drives than any other OEM. With integrated HP technology, such as Systems Insight Manager, SmartStart and HP Flash utilities, you can take advantage of pre-failure alerts and avoid costly data loss and un-planned downtime. HP also provides a pre-failure warranty allowing you to replace a degrading drive before it actually fails. To further simplify support processes, HP drives are covered under the server CarePack.
