The Cheetah 36LP family has the following standard features:

Integrated Ultra160 SCSI controller
Multimode SCSI drivers and receiverssingle-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

Media characteristics

The media used on the drive has a diameter of approximately 3.3 inches (84 mm). The aluminum substrate is
coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability
and environmental protection.

Performance

Supports industry standard Ultra3 SCSI interface
Programmable multi-segmentable cache buffer (see Section 4.5)
10,033 RPM spindle. Average latency = 2.99 ms
Command queuing of up to 64 commands
Background processing of queue
Supports start and stop commands (spindle stops spinning)

Reliability

1,200,000 hour MTBF
LSI circuitry
Balanced low mass rotary voice coil actuator
Incorporates industry-standard Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.)

Compatibility

This drive is compatible with any of our SCSI controllers
