FCC Notice This equipment generates and uses radio frequency energy and, if not installed
and used properly; that is, in strict accordance with the manufacturer's
instructions, may cause interference to radio and television reception. It has
been type tested and found to comply with the limits for a Class B computing
device in accordance with the specifications in Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference in a
residential installation. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause interference
to radio or television reception, which can be determined by turning the
equipment on and off, you are encouraged to try to correct the interference by
one or more of the following measures:
• Reorient the receiving antenna.
• Relocate the computer with respect to the receiver.
• Move the computer into a different outlet so that the computer and receiver
are on different branch circuits.
If necessary, you should consult the dealer or an experienced radio/television
technician for additional suggestions. You may find the following booklet
prepared by the Federal Communications Commission helpful:
How to Identify and Resolve Radio-TV Interference Problems

Overview of the Drives

What are the Drives?
The CFP2107 series is a family of high performance 3.5-inch low-profile (1.0 inch
high) 2.1GB (formatted) disk drives. They all offer 8.5 millisecond average seek
time for Reading, 9.0 millisecond seek time for Writing, with an average latency
of only 4.17 ms. High capacity is achieved by utilizing a zone density recording
technique using 15 recording zones at an areal density of 317 Mbits per square
inch. These drives feature high performance while maintaining low power
consumption to reduce power supply current and system cooling requirements in
disk arrays.
They are designed to operate on the Small Computer System Interface (SCSI)
and are SCSI-2/3 command compatible. The mechanical and major electronic
components are identical between the models and differ only in the host
interface implementation:

The CFP2107WD drive is documented separately in the CFP2107WD SCSI Wide
Differential Intelligent Disk Drive Product Manual. The remainder of the
drives, which are documented in this manual, are referred to collectively in this
manual as “the drive” for simplicity.
Differences Between the Models
The three drive models differ only on the host interface implementation:
CFP2107E: SCSI 80-pin Wide Single Connector Attachment (SCA) interface
designed for applications such as Redundant Arrays in which the drives are
plugged directly into a backplane. The drive also implements a Wide SCSI
interface for high interface bandwidth.
CFP2107S: SCSI 50-pin standard interface designed for applications which
implement the standard SCSI-2 architecture.
CFP2107W: SCSI 68-pin Wide interface designed for applications which
require high interface bandwidth and the option of cabled interconnect. The
drive utilizes the Unitized Connector defined by the Small Form Factor
Committee (refer to SFF-8009). The Unitized Connector combines the SCSI-3 P-

connector Wide interface, the standard 4-pin power and a 2mm pin pitch
Auxiliary connector into a single molded assembly.
CFP2107WD: SCSI 68-pin wide differential interface designed for applications
which require high interface bandwidth and the option of cabled interconnect.
The drive utilizes the Unitized Connector defined by the Small Form Factor
Committee (refer to SFF-8009). The Unitized Connector combines the SCSI-3 P-
connector Wide interface, the standard 4-pin power and a 2mm pin pitch
Auxiliary connector into a single molded assembly. The wide SCSI differential
implementation conforms to the SCSI-3 Parallel Interface Specification 855D.
Features of the Drive
The drive provides the following features:
•Automatic Spindle Synchronization
•512 KB segmentable cache buffer with adaptive cache management
•Least Recently Used (LRU) Cache replacement
•Automatic on-the-fly data error correction utilizing a 96-bit Reed-Solomon
EDAC.
•Independent 48-bit CRC miscorrection detection.
•On the fly header error detection and correction.
•High performance rotary voice coil actuator with embedded servo system
•No thermal recalibration required to maintain performance levels
•High Shock resistance
•Automatic actuator latch against the inner stop upon power down with
dedicated landing zone
•Active Termination with removable Resistor Packs
•Active Negation output drivers for greater interface reliability
•SCSI-2/3 Compatibility
•Dual Microprocessor-controlled diagnostic routines that automatically
execute at start-up
•Sealed HDA
•Down-loadable Code through SCSI Interface
•1,7 run length limited code
•Programmable Block Size (512 or 1024)
•Tagged Command Queuing with Seek Re-ordering and Write/Read
