Ultrastar 9LZX and 18ZX hard disk drives
Superior performance, reliability, and capacity for workstation, subsystem, and PC and enterprise server applications
PDF version
Highlights
Ultrastar 9LZX 3.5-inch 9.1 GB high-performance disk drive
|
Rotational speeds of up to 10,020 RPM and average seek times as fast as 5.3 ms provide exceptional performance.
The IBM Drive-Temperature Indicator Processor (Drive-TIP*) feature automatically monitors disk drive temperature and alerts the SCSI
drive controller when the recommended temperature is exceeded.
Industry-leading server drive areal densities of 2024 Mbits/sq. in. result in lighter weight drives with improved environmentals.
A buffer size of 4.0 MB provides outstanding performance, especially for data-intensive applications that access data sequentially.
Proven drive technology
The newest members of the Ultrastar* family of disk drives provide excellent reliability and performance for servers. Migration to the 9LZX and 18ZX drives is simplified by the use of
magnetoresistive extended (MRX) advanced head technology, No-ID* sector formatting, a powerful custom controller with hardware assist functions, a proven PRML data channel, and the
field-proven design, electronics, and mechanics of previous generations of the award-winning Ultrastar family.
Featuring 9.1 GB (low profile) and 18.2 GB, the Ultrastar 9LZX and 18ZX provide exceptional performance. These drives combine a rotational speed of 10,020 RPM and seek times as fast as 5.3
ms with the IBM custom controller that incorporates command queuing and a large programmable multisegmented cache up to 4.0 MB. Hardware automation further reduces SCSI command overhead and
cache accessing time.
Reliability leadership
Ultrastar 18ZX 3.5-inch 18.2 GB high-performance disk drive
|
The new Ultrastar disk drives support the failure prediction capabilities of S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology), IBM Predictive Failure Analysis* (PFA), and the
IBM-exclusive Drive-TIP. These features help ensure the maximum possible protection for end user data.
Support for advanced applications
Improvements in data throughput are increasingly important in advanced applications. Online transaction and analytical processing (OLTP, OLAP) and other data-intensive applications -- along
with Internet servers and storage area network servers -- can all achieve the maximum benefit from the advanced technology of these Ultrastar disk drives.
Advanced interfaces
IBM offers a comprehensive set of parallel and serial host interfaces, including Ultra2 SCSI LVD (fast, wide, SCA II), Serial Storage Architecture (SSA), and Fibre Channel Arbitrated Loop
(FCAL).
