Description:
| Cheetah 9LP drives combine magnetoresistive (MR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a wide Ultra2 SCSI interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.

Features:
- Integrated Ultra/Ultra2 SCSI controller
- Multimode SCSI drivers and receivers—single-ended (SE) and low voltage differential (LVD)
- 16 bit I/O data bus
- Asynchronous and synchronous data transfer protocol
- Firmware downloadable via SCSI interface
- Selectable even byte sector sizes from 180 to 4,096 bytes/sector
- Programmable sector reallocation scheme
- Flawed sector reallocation at format time
- Programmable auto write and read reallocation
- Reallocation of defects on command (post format)
- Enhanced ECC correction capability up to 185 bits
- Sealed head and disc assembly
- No preventative maintenance or adjustment required
- Dedicated head landing zone
- Embedded servo design
- Self diagnostics performed when power is applied to the drive
- 1:1 Interleave
- Zoned bit recording (ZBR)
- Vertical, horizontal, or top down mounting
- Dynamic spindle brake
- 1,024 kbyte data buffer (or 4,096 kbyte option)
- Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for “LC” model drives
- SCAM (SCSI Configured AutoMagically) plug-n-play level 2 compliant, factory set to level 1
