(1)Interface (SCSI bus) test

The operations of the SCSI bus and data buffer on the IDD are checked with the WRITE BUFFER and READ BUFFER commands.

(2)Basic operation test

The basic operations of the IDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1).

(3)Random/sequential read test

The positioning (seek) operation and read operation are tested in random access and sequential access modes with the READ, READ EXTENDED, or VERIFY command.

(4)Write/read test

By using a data block in the internal test space, the write/read test can be executed with an arbitrary pattern for a disk drive in which user data is stored.

6.2Maintenance Information

6.2.1Maintenance requirements

(1)Preventive maintenance

Preventive maintenance such as replacing air filters is not required.

CAUTION

Damage

Do not open the DE in the field because it is completely sealed.

(2)Service life

The service life under suitable conditions and treatment is as follows. The service life is depending on the environment temperature. Therefore, the user must design the system cabinet so that the average DE surface temperature is as possible as low.

∙

DE surface temperature: 45°C or less

5 years

∙

DE surface temperature: 46°C to 50°C

4 years

∙

DE surface temperature: 51°C to 55°C

3 years

∙

DE surface temperature: 56°C and more

strengthen cooling power so that DE

 

 

surface temperature is 55°C or less.

Even if the IDD is used intermittently, the longest service life is 5 years.

This drive utilizes advanced technology designs, such as a fluid dynamic bearing spindle motor, which enhances reliability and reduces noise levels. Its SCSI interface allows for multiple device connections, making it ideal for enterprise-level applications where performance is critical.

The MAE3091LC, on the other hand, also features a 10,000 RPM spindle speed but caters to a slightly lower capacity of 9.1 GB. Its Ultra SCSI interface ensures swift data throughput, making it suitable for data-intensive applications. The drive’s robust construction is designed to withstand the rigors of continuous operation, offering an MTBF (Mean Time Between Failures) rating that speaks to its reliability and endurance in demanding environments.

Moving on to the MAF3364LP, this model offers similar capacity to the MAF3364LC but operates at a lower power consumption rating, making it an eco-friendly choice for users who are conscious of energy usage. It retains the same high-speed performance capabilities, thanks to its efficient design and technology integrations.

The MAG3182LC is known for its high-capacity support and performance balance, with 18.2 GB of storage and a spindle speed of 10,000 RPM. It boasts enhanced data integrity features and advanced error correction technologies that allow for high data accuracy and reliability, ensuring that enterprises can depend on their stored information.

Lastly, the MAE3182LC offers a mix of performance and capacity, with its 18.2 GB storage. Utilizing a SCSI interface and maintaining a robust build, this drive is particularly suited for server environments that demand long continuous running times without compromising reliability.

In summary, these Fujitsu drives encompass advanced technologies, robust designs, and high-speed performance, catering to various needs from enterprise storage to high-demand applications. Their characteristics ensure that users receive not only adequate capacity but also reliability and efficiency, solidifying Fujitsu's reputation in the storage solutions market.
