1.1Standard Features

(1)Compactness

Since the SCSI controller circuit is embedded in the standard 3.5 type fixed disk drive form factor, the IDD is extremely compact. The IDD can be connected directly to the SCSI bus of the host system.

(2)SCSI standard

The IDD provides not only SCSI basic functions but also the following features:

Arbitration

Disconnection/Reconnection

Data bus parity

The SCSI commands can manipulate data through logical block addressing regardless of the physical characteristics of the disk drive. This allows software to accommodate future expansion of system functions.

(3)8-bit SCSI/16-bit SCSI

The IDD has 16-bit data bus width (16-bit SCSI), which have the wide transfer function suitable for SCSI-2. 8-bit data bus is available only with NP model.

See subsection 5.3.2 for details of the bus width setting.

For the ultra SCSI model, number of connectable SCSI devices on the same SCSI bus is varied as follows.

8-bit SCSI:

8 drives max. (option for NP model)

16-bit SCSI:

16 drives max.

(4)High speed data transfer

Such a high data transfer rate on the SCSI bus can be useful with the large capacity buffer in the IDD.

8-bit SCSI:

The data transfer rate on the SCSI bus is 40 MB/s maximum at the

 

 

synchronous mode.

16-bit SCSI:

The data transfer rate on the SCSI bus is 320 MB/s maximum at the paced

 

 

transfer synchronous mode.

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.
