Mounting Installation

Damage

5-5

 

 

 

1. When dismounting the drive which is mounted on the system

 

 

while power is supplied to it.

 

 

The drive to be dismounted must be separated from the

 

 

loop. Dismounting the drive which is not separated from

 

 

the loop may cause an unexpected error.

 

 

If the drive is not separated from the loop, issue an LPB to

 

 

the drive from the initiator in a primitive sequence of the

 

 

order set.

 

 

It is recommended to stop the spindle motor prior to this

 

 

loop separation operation. The spindle motor can be

 

 

stopped by a START/STOP command. It takes about 30

 

 

seconds for the spindle motor to stop completely.

 

 

Then, dismount the drive using the drive

 

 

mounting/dismounting mechanism, etc. of the system. If

 

 

the drive is dismounted while the spindle motor is running,

 

 

special care is required to avoid excessive vibration or

 

 

shock to the drive. It is recommended to stop the operation

 

 

once the SCA connector breaks off contact and wait until

 

 

the spindle motor stops (about 30 seconds) before dismount

 

 

the drive.

 

 

When storing or transporting the drive, put it in an

 

 

antistatic bag. (Shown in Section 5.1).

 

 

2. When dismounting the drive which is mounted on the system

 

 

while power is not supplied to it.

 

 

Do not move the drive until the drive stops completely

 

 

(about 30 seconds if the spindle motor was stopped by a

 

 

START/STOP UNIT command, and about 30 seconds after

 

 

powering-off when the power was simply turned off).

 

 

Then, dismount the drive using the drive

 

 

mounting/dismounting mechanism, etc. of the system.

 

 

When storing or transporting the drive, put it in an

 

 

antistatic bag. (Shown in Section 5.1).

 

 

Data loss

6-4

 

When the SEND DIAGNOSTIC command terminates with the

 

 

CHECK CONDITION status, the INIT must collect the error

 

 

information using the REQUEST SENSE command. The RECEIVE

 

 

DIAGNOSTIC RESULTS command cannot read out the error

 

 

information detected in the self-diagnostics.

 

 

Caution

6-5

 

1. To avoid injury, do not touch the mechanical assembly during

 

 

disk drive operation.

 

 

2. Do not use solvents to clean the disk drive.

Fujitsu MAP3147FC, MAP3735FC manual Important Alert Items

MAP3735FC, MAP3147FC specifications

Fujitsu has been a prominent player in the hard disk drive market, with its MAP3147FC and MAP3735FC models standing out in terms of performance and reliability. These drives are engineered to meet the growing demands of enterprise applications, providing robust solutions for data storage in critical environments.

The Fujitsu MAP3147FC, with a capacity of 147 GB, is optimized for high-speed data access and storage efficiency. This 3.5-inch SCSI drive operates at a rotational speed of 15,000 RPM, ensuring rapid data retrieval and minimized latency, making it ideal for applications requiring quick transaction processing. It features a 4 Gbps Fibre Channel interface, which enhances connectivity and system integration, promoting seamless communication between devices in storage area networks.

On the other hand, the MAP3735FC model offers a higher capacity of 300 GB. It shares similar specifications with its counterpart, including the 15,000 RPM speed, which guarantees top-notch performance for mission-critical applications. The MAP3735FC, like the MAP3147FC, incorporates advanced technologies such as Command Queuing, which optimizes the execution of multiple read and write commands in a queue. This feature is particularly beneficial in environments with high I/O demands, improving overall system throughput and efficiency.

Both drives utilize sophisticated error correction techniques, ensuring data integrity and reliability. They are equipped with features like S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology), which continuously monitors the health of the drives and helps predict potential failures, allowing for proactive maintenance and data protection.

In terms of physical characteristics, both models are designed to withstand the rigors of continuous operation. They are built with a rugged casing to protect against vibration and shock, making them suitable for use in enterprise-level servers and storage systems. Their design also allows for efficient heat dissipation, which is critical for maintaining optimal performance during extended use.

In summary, Fujitsu's MAP3147FC and MAP3735FC hard drives embody a combination of high speed, reliability, and advanced features tailored for enterprise environments. Their robust performance, large storage capacities, and reliable error correction technologies make them an excellent choice for businesses looking to optimize their data storage solutions and ensure seamless operation in demanding applications. With Fujitsu's commitment to quality and innovation, these models continue to meet the evolving needs of the data storage industry.
