Abstract
Features and technical details of the 9.1GB Wide Ultra2 SCSI hard disk drive
Content
At a glance
IBM continues to offer leading-edge hard disk technology by expanding its family of 7200 rpm drives with the 9.1GB Wide Ultra2 SCSI Hard Disk Drive (HDD). This drive offers outstanding performance and storage. It also features the Wide Ultra2 SCSI interface, which is capable of a maximum synchronous burst transfer rate of 80MB/sec. To ensure that this hard drive provides maximum quality, reliability, and performance, IBM performs extremely rigorous testing and qualification in a variety of environments.
This HDD has the industry standard Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) feature that can provide advanced warning of an impending drive failure when used with the appropriate software, for example, IBM's Netfinity Manager (TM). To protect customer investments in Predictive Failure Analysis (TM) server reliability software and hardware, S.M.A.R.T. implements a compatible failure reporting scheme. If during the warranty period this drive predicts imminent failure, the drive is immediately eligible for replacement.
The advanced design of the 9.1GB Wide Ultra2 SCSI HDDs provides high levels of reliability in a high-performance solution. Use of the latest technologies, such as magneto-resistive (MR) heads, provides the foundation for a more reliable design. Increasing platter densities results in fewer parts and higher reliability and performance.
The IBM 68-pin drive to 50-pin cable converter (01K1326) enables the use of these new drives in older systems. This converter allows these newer, faster Wide Ultra2 SCSI drives to be used in systems designed for older narrow (50-pin) devices. When a 68-pin hard drive is adapted for use on 50-pin cabling, its highest interface data transfer rate is reduced to be compatible with the existing cable and SCSI bus adapter.
Note: When referring to hard disk drive capacity MB = 1 million bytes; GB = 1000 million bytes. Actual capacities vary based on different operating environments.

Supported Operating Systems:
The 9.1GB HDD is supported in the following environments:
- Microsoft MS DOS 6.22
- PC DOS 7.0
- Windows 3.1
- Windows 95 Version A
- Windows 95 Version B
- Windows NT 4.0
- Windows NT 4.0 with Service Pack 3
- Windows 98
- Windows 98 with Service Pack 1 Version 1914
- OS/2 4.0 Warp
- NetWare 4.x
Compatibility:
This HDD adheres to the following American National Standards Institute (ANSI) standards:
- SCSI X3.131:1986 (SCSI-1)
- SCSI X3.131:1994 (SCSI-2)
- SCSI X3.253:1995 (SCSI-3 Parallel Interface)
- T10/1142D REV 14 SPI-2 (SCSI-3 Parallel Interface Version 2)
- Under DOS, the maximum partition size is approximately 2 GB. You may have to install multiple partitions to realize the full capacity of the drive.
- These drives perform as Wide Ultra SCSI devices supporting the slower burst data transfer rates when used in older systems that have Ultra (or other pre Ultra2) devices sharing the same cable.
- When using only Wide Ultra2 devices, up to 15 devices may be connected to the controller on a total bus length that cannot exceed 12 meters.
To achieve the drive's potential high reliability level, the system should provide sufficient air movement to maintain the drive surface temperature below 60 deg C.
