Ready to excel in the most demanding server-class environments
Highlights:
- Rotational speed of 10,000 rpm and average seek times as low as 4.7 ms provide outstanding performance
- Capacities of 146, 73, 36, and 18GB from a single server drive family for unrivaled configuration flexibility and ease of integration
- First ever server-class drive to implement antiferromagnetically-coupled (AFC) media, combined with advanced head/disk design, resulting in high reliability for today�fs critical server-class environments
- Enhanced servo technology (Rotational Vibration Safeguard) nullifies the effect of rotational vibration in multi-drive cabinets, overcoming an industry hurdle to optimal server performance
Advanced drive technology
Introducing the sixth generation of Ultrastar 10,000 rpm disk drives. The Hitachi Ultrastar 146 Z10 drive family offers high quality and superior performance. These drives feature more powerful processors and read/write channels to excel in server-class environments.
To achieve maximum I/O performance, the drives combine fast seek times, large 8 MB multi-segmented buffers, a sophisticated command queuing algorithm, hardware automation, and superior data rates (825 Mbps). Ultrastar 146 Z10 drives include new servo technology (Rotational Vibration Safeguard "RVS"), employed to counteract the effects of rotational vibration that commonly occur in multi-drive cabinets. They also employ fifth-generation giant magnetoresistive (GMR) head technology to double areal density from previous generation drives (26.3 Gbits/sq. in.) and boost performance. In addition, highly efficient No-ID* sector formatting enables more data to be stored per disk.
Reliability features
The Ultrastar 146 Z10 family of server-class drives is the first of its class to incorporate our storage breakthrough technology antiferromagnetically-coupled (AFC) media. Informally known as �gpixie dust�h, this technology sandwiches a three-atom thick layer of ruthenium, a precious metal, between two magnetic layers on a disk. AFC technology provides greater stability of the recording media, enhancing reliability.
Drive Fitness Test enables drive self-testing and analysis for more robust system management. To help ensure data protection, Hitachi Ultrastar drives include exclusive reporting tools, such as Predictive Failure Analysis* (to signal potential drive problems) and Drive-TIP* (to monitor the drive temperature and avoid malfunctions).
In addition, load/unload technology and glass substrate disks increase reliability of Ultrastar drives by providing a more robust solution at high rotational speeds.
Outstanding environmentals
Hitachi Ultrastar drives provide extremely quiet operation. The tri-laminate drive cover reduces both idle and seek acoustics while an enhanced spindle motor driver enables smoother commutation for less noise. Moreover, the Ultrastar 146Z10 delivers an outstanding power efficient design.
Support for advanced applications and interfaces
Hitachi Ultrastar drives provide high data throughput for data-intensive applications with a choice of 2 Gbit Fibre Channel and Ultra320 SCSI (backward-compatible) interfaces. The Ultra320 SCSI adds greater speed, reduced overhead, improved diagnostic capabilities and data protection.
Compatibility
This drive is compatible with any of our SCSI hotswap trays/caddies. |
