Data loss

2-5

 

For MAP series, Reed Solomon codes are applied for their ECC.

 

 

The sector-data is divided into 6 interleaving sectors, and ECC is

 

 

performed in each sector where the maximum number of errors

 

 

(up to 5 byte) can be corrected. [Total maximum byte: 5 byte ⋅ 6

 

 

( interleave) = 30 byte]

 

 

If the error of read sector keeps allowable error byte number,

 

 

correction is performed.

 

 

However, if error byte exceeds its allowable number, correction

 

 

may not be performed properly.

 

 

Hot temperature

 

 

To prevent injury, do not handle the drive until after the device has

5-1

 

cooled sufficiently after turning off the power. The DE and LSI

 

 

become hot during operation and remain hot immediately after

 

 

turning off the power.

 

 

Data loss

 

 

1. The user must not change the setting of terminals not described

5-5

 

in this section. Do not change setting status set at factory

 

 

shipment.

 

 

2. Do not change the setting of terminals except following setting

 

 

pins during the power is turned on.

 

 

• Write protect: CN2 9-10 (NP model only)

 

 

3. To short the setting terminal, use the short plug attached when

 

 

the device is shipped from the factory.

 

Damage

5-11

1.Make sure that system power is off before connecting or disconnecting cables.

2.Do not connect or disconnect cables when power is on.(except NC model)

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.
