Description:
Cheetah 36LP drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood
(PRML) read channel electronics, embedded servo technology, and a wide Ultra160 SCSI interface to provide
high performance, high capacity data storage for a variety of systems including engineering workstations, network
servers, mainframes, and supercomputers.
Ultra160 SCSI uses negotiated transfer rates. These transfer rates will occur only if your host adapter supports
these data transfer rates and is compatible with the required hardware requirements of the I/O circuit type. This
drive also operates at SCSI-1 and SCSI-2 data transfer rates for backward compatibility with non-Ultra/Ultra2/
Ultra160 SCSI host adapters.

Features:
- Integrated Ultra160 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 (supports Ultra160 transfer rate)
- Firmware downloadable via SCSI interface
- Selectable even byte sector sizes from 512 to 2,064 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)
- ECC maximum burst correction length of 240 bits with a guaranteed burst correction length of 233 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
- Zoned bit recording (ZBR)
- Vertical, horizontal, or top down mounting
- Dynamic spindle brake
- 4,096 kbyte data buffer (16,384 kbytes on LWV and LCV models)
- Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for LC and LCV model drives
- Drive Self Test (DST)
- Supports SCSI bus fairness
