5.6Confirming Operations after Installation and Preparation for use

5.6.1Confirming initial operations

This section describes the operation check procedures after power is turned on. Since the initial operation of the IDD depends on the setting of the motor start mode, check the initial operation by either of the following procedures.

(1)Initial operation in the case of setting so that motor starts at powering-on

a)When power is turned on, the LED blinks an instant and the IDD executes initial self- diagnosis.

b)If an error is detected in the initial self-diagnosis, the LED blinks periodically.

Remark:

The spindle motor may or may not start rotating in this stage.

c)When the IDD status is idle, the LED remains off (when the initiator accesses the IDD via the SCSI bus, the LED lights).

(2)Initial operation in the case of setting so that motor starts with START/STOP command

a)When power is turned on, the LED blinks an instant and the IDD executes initial self- diagnosis.

b)If an error is detected in the initial self-diagnosis, the LED blinks.

c)The spindle motor does not start rotating until the START/STOP UNIT command for the start is issued. The INIT needs to issue the START/STOP UNIT command to start the spindle motor by the procedure in Subsection 5.6.2.

d)The disk drive enters the READY status in 60 seconds after the START/STOP UNIT command is issued. At this time, the IDD reads "system information" from the system space on the disk.

e)The LED blinks during command execution.

(3)Check items at illegal operation

a)Check that cables are mounted correctly.

b)Check that power and voltages are supplied correctly (measure them with the IDD power connection position).

c)Check the setting of each setting terminal. Note that the initial operation depends on the setting of the motor start mode and LED display requirements.

MAP3735NC/NP, MAP3367NC/NP, MAP3147NC/NP specifications

Fujitsu's MAP3147NC/NP, MAP3367NC/NP, and MAP3735NC/NP hard disk drives represent a robust solution for businesses seeking reliable data storage options. These models are part of Fujitsu’s extensive line of high-performance hard drives that cater to various organizational needs, from servers to high-capacity data storage systems.

One of the standout features of these hard drives is their speed. The MAP3147NC/NP operates at a spindle speed of 10,000 RPM, ensuring rapid data access and retrieval. This speed is essential for environments requiring quick data transactions, making it suitable for enterprise-level databases and high-performance computing applications.

The capacity range across these models is designed to meet varying storage requirements. The MAP3147NC offers 147 GB, while the MAP3367NC provides 67 GB, and the MAP3735NC boasts a generous capacity of 35 GB. This diversity allows organizations to select the drive that best fits their data storage and performance needs while maintaining a scalable storage solution.

In terms of technology, the drives incorporate advanced features such as Serial Attached SCSI (SAS) interface, which enhances data throughput and reliability compared to traditional Parallel SCSI interfaces. SAS technology enables these drives to support multiple device connections while ensuring high-performance throughput, essential for modern enterprise environments.

The drives employ a 64 MB cache, providing a significant performance boost by allowing for quicker access to frequently used data. This capability improves overall system responsiveness, especially in applications requiring high input/output operations per second (IOPS).

Moreover, the MAP3147NC/NP, MAP3367NC/NP, and MAP3735NC/NP series are designed with data integrity in mind. They include features such as Error Correction Code (ECC) and background error scanning, which work together to maintain the integrity of stored data and minimize the risk of data loss.

In conclusion, Fujitsu’s MAP3147NC/NP, MAP3367NC/NP, and MAP3735NC/NP hard disk drives provide a blend of performance, capacity, and reliability. With their fast spindle speeds, robust data throughput via SAS technology, and enhanced cache memory, these drives are ideal for enterprises requiring durable and efficient data storage solutions in high-demand environments. As organization needs evolve, these drives offer scalability and reliability to support diverse applications and workloads.
