IMPORTANT

When Write cache is enabled, you should ensure that the cashed data is surely flushed to the disk media before you turn off the drive's power. To ensure it, you should issue either the SYNCHRONIZE CASHE command or the STOP UNIT command with specifying “0” to the Immediate bit and then confirm that the command is surely terminated with the GOOD STATUS.

(9)Command queuing feature

The HDD can queue maximum 128 commands, and optimizes the issuing order of queued commands by the reordering function. This feature realizes the high speed processing.

(10)Reserve and release functions

The HDD can be accessed exclusively in the multi-host or multi-initiator environment by using the reserve and release functions.

(11)Error recovery

The HDD can try to recover from errors in SCSI bus or the disk drive using its powerful retry processing. If a recoverable data check occurs, error-free data can be transferred to the initiator after being corrected in the data buffer. The initiator software is released from the complicated error recover processing by these error recovery functions of the HDD.

(12)Automatic alternate block reassignment

If a defective data block is detected during read or write the HDD can automatically reassign its alternate data block.

(13)Programmable data block length

Data can be accessed in fixed-block length units. The data block length is programmable, and can be specified at initializing with a multiple of four within the range of 512 to 528 bytes.

IMPORTANT

Error rate increase

1.The drive format at factory shipment is generally 512 byte.

2.The Recoverable Error of the drive might increase when the format would be modified from 512 bytes to the following values: 516 bytes, 520 bytes, 524 bytes, and 528 bytes.

3.The Recoverable Error referred in 2) is sense data (1-13-xx).

MAW3147NC/NP, MAW3073NC/NP, MAW3300NC/NP specifications

Fujitsu has established itself as a key player in the world of hard disk drives, and their MAW3073NC/NP, MAW3300NC/NP, and MAW3147NC/NP models showcase exemplary engineering and innovative technology. These drives are designed primarily for enterprise applications, providing robust performance, reliability, and data integrity in demanding environments.

One of the standout features of the Fujitsu MAW series is its high storage capacity. The MAW3073NC/NP model comes with a generous 73 GB capacity, while the MAW3300NC/NP boasts 300 GB, and the MAW3147NC/NP offers 147 GB of storage. This range makes them suitable for various applications, from databases to data-intensive software.

The drives utilize the latest Serial Attached SCSI (SAS) interface, which ensures high speed and efficiency in data transfer. SAS technology provides better bandwidth and performance compared to older parallel SCSI interfaces, enabling faster access to data and improved overall system responsiveness. With rotational speeds of 10,000 RPM, these drives further enhance performance, enabling faster read and write times, which is critical for enterprise applications that require quick data retrieval.

Another noteworthy characteristic of the Fujitsu MAW series is their advanced error recovery and data integrity features. The drives are equipped with sophisticated error correction mechanisms and management systems that help maintain data integrity, ensuring that the data remains intact even in the event of power loss or system failure. This reliability is paramount for enterprise environments where data loss can result in significant operational disruptions.

In terms of physical design, these drives are built to endure the rigors of high-demand environments. They feature a robust construction that allows for efficient heat dissipation, minimizing the risks associated with overheating. Additionally, their form factor is designed for easy integration into various server and storage systems, making them versatile solutions for IT infrastructure.

Fujitsu's commitment to sustainability is also evident in the MAW series with their energy-efficient operation and reduced power consumption, contributing to decreased overall operational costs. With a combination of high performance, reliability, and sustainability, the Fujitsu MAW3073NC/NP, MAW3300NC/NP, and MAW3147NC/NP hard drives stand out as formidable choices for organizations looking to optimize their data storage solutions. They embody the cutting-edge technology and quality that Fujitsu is known for in the enterprise storage market.
