[signal]

[I/O]

[Description]

DIOR–

I

DIOR– is the strobe signal asserted by the host to read device

 

 

registers or the data port.

HDMARDY–

I

HDMARDY– is a flow control signal for Ultra DMA data in

 

 

bursts. This signal is asserted by the host to indicate to the device

 

 

that the host is ready to receive Ultra DMA data in bursts.

 

 

The host may negate HDMARDY- to pause an Ultra DMA data in

 

 

burst.

HSTROBE

I

HSTROBE is the data out strobe signal from the host for an Ultra

 

 

DMA data out burst. Both the rising and falling edge of

 

 

HSTROBE latch the data from DATA 0-15 into the device. The

 

 

host may stop generating HSTROBE edges to pause an Ultra

 

 

DMA data out burst.

INTRQ

O

Interrupt signal to the host.

 

 

This signal is negated in the following cases:

 

 

– assertion of RESET– signal

 

 

– Reset by SRST of the Device Control register

 

 

– Write to the command register by the host

 

 

– Read of the status register by the host

 

 

– Completion of sector data transfer

 

 

(without reading the Status register)

 

 

When the device is not selected or interrupt is disabled, the

 

 

INTRQ

 

 

Signal shall be in a high impedance state.

CS0–

I

Chip select signal decoded from the host address bus. This signal

 

 

is used by the host to select the command block registers.

CS1–

I

Chip select signal decoded from the host address bus. This signal

 

 

is used by the host to select the control block registers.

DA 0-2

I

Binary decoded address signals asserted by the host to access task

 

 

file registers.

KEY

–

Key pin for prevention of erroneous connector insertion

PIDAG–

I/O

This signal is an input mode for the master device and an output

 

 

mode for the slave device in a daisy chain configuration. This

 

 

signal indicates that the slave device has been completed self

 

 

diagnostics.

 

 

This signal is pulled up to +5 V through 10 kΩ resistor at each device.

CBLID–

I/O

This signal is used to detect the cable type (80 or 40-conductor

 

 

cable) installed in the system. This signal is pulled up to +5 V

 

 

through 10 kΩ resistor at each device.

DASP–

I/O

This is a time-multiplexed signal that indicates that the device is

 

 

active and a slave device is present.

 

 

This signal is pulled up to +5 V through 10 kΩ resistor at each device.

MPE3XXXAT specifications

The Fujitsu MPE3XXXAT series is a robust line of hard disk drives (HDDs) known for their reliability, performance, and advanced technology. Designed primarily for enterprise storage solutions, these drives cater to high-demand environments such as data centers, servers, and workstations. With capacities ranging from hundreds of gigabytes to several terabytes, the MPE3XXXAT series offers scalable storage options to accommodate a variety of applications.

One of the standout features of the MPE3XXXAT series is its high rotational speed. With most models operating at 7200 RPM, these drives ensure faster data access and improved read/write performance. This speed makes them ideal for applications requiring quick data retrieval, such as database management and data-intensive workloads. Furthermore, the series utilizes a Serial ATA (SATA) interface, which facilitates seamless connectivity and compatibility with a wide range of systems.

The Fujitsu MPE3XXXAT series is built with advanced technologies that enhance durability and longevity. Notably, the drives incorporate advanced error correction algorithms and vibration resistance features, which are crucial for maintaining data integrity over time. This is particularly important in multi-drive environments where vibrations from one drive can affect the performance of others. The drives are also designed with low power consumption in mind, contributing to energy savings without compromising performance.

In terms of data security, the MPE3XXXAT series supports various security features that protect against unauthorized access. These include ATA security features that enable password protection and robust encryption to safeguard sensitive information from potential breaches. This aspect is particularly significant for enterprises that handle confidential data and require stringent security measures.

The operational temperature range of the MPE3XXXAT drives is optimized for demanding environments, allowing them to function effectively in a variety of conditions. Their reliability is backed by an impressive Mean Time Between Failures (MTBF), which signifies their resilience and the manufacturer's commitment to quality.

Overall, the Fujitsu MPE3XXXAT series stands out as a reliable choice for enterprise storage needs. With its blend of high speed, capacity, durability, and security features, it addresses the challenges faced by modern data centers and businesses that require efficient data management solutions. Whether for backup, archival, or active data storage, the MPE3XXXAT series is designed to deliver consistent performance and peace of mind for users.
