XYCOM XVME-957 VMEBUS Mass Storage Subsystem No Hard Disk

Product overview

XVME-957 Mass Storage Sub-system

Provides a high-capacity IDE hard disk drive and a 1.44 Mbyte 3.5" floppy disk drive in a single VMEbus slot. Designed to be compatible with Xycom's VME PC/AT processors. Form Factor: 6U (Double)

The XYCOM XVME-957 VMEBUS Mass Storage Subsystem (without hard drives) is designed to meet the demand for large capacity, high-speed data storage in industrial environments. It abandons traditional hard disk storage media and adopts more advanced storage technologies, such as flash memory storage, solid-state storage arrays, etc., to achieve efficient storage and fast reading of data. This subsystem is connected and communicates with other devices (such as industrial computers, controllers, etc.) through the VMEBUS bus, and can quickly and stably transmit data. It can be widely used in data recording of industrial automation production lines, video storage of industrial monitoring systems, data acquisition and storage of scientific research, and other scenarios, providing users with efficient and reliable data storage services.

Core Features

（1） Advantages of No Hard Disk Storage Technology

High reliability: The design without a hard drive avoids the risk of failure caused by mechanical components such as magnetic heads and motors in traditional hard drives, such as wear and tear on the hard drive read/write heads and scratches on the disk, greatly reducing the probability of hardware failure. Flash storage or solid-state storage arrays, which have no mechanical structure, have the characteristics of earthquake resistance and impact resistance. Even in industrial sites with large vibrations and harsh environments, they can ensure the stability and integrity of data storage, effectively reduce the risk of data loss caused by storage device failures, and improve the reliability of industrial system operation.

High speed data read and write: Using advanced storage chips and optimized storage algorithms, the data read and write speed far exceeds traditional hard drives. The sequential read speed can reach several hundred MB per second, and the sequential write speed can also reach a high level, such as 100MB/s or more, which can quickly store and read large amounts of data. In industrial automation production lines, various types of data related to equipment operation, such as high-frequency data collected by sensors, can be recorded in real time and quickly; In video surveillance systems, high-definition video images can be stored smoothly to ensure the integrity and continuity of monitoring data.

Low power consumption and long lifespan: Compared to traditional hard drives, non hard drive storage has lower power consumption, which can reduce overall system energy consumption and lower operating costs. At the same time, flash storage and other media have a long service life and can withstand tens of thousands or even more erase and write operations, effectively extending the service life of the storage subsystem, reducing equipment replacement frequency, and lowering maintenance costs.

（2） Characteristics of VMEBUS bus

High speed data transmission: The VMEBUS bus has high-speed data transmission capability, with a maximum data transmission rate of up to 40MB/s, which can meet the requirements of a large number of storage subsystems for data transmission speed. In industrial environments, the collected data can be quickly transmitted to the storage subsystem for storage, or read from the storage subsystem and transmitted to other devices for processing, ensuring efficient circulation of data within the system.

Stable and reliable communication: The communication protocol based on the VMEBUS bus has high stability and reliability, and can maintain stable data transmission in complex industrial electromagnetic interference environments, reducing data transmission errors and losses. Through the electrical isolation and signal conditioning technology of the bus, the anti-interference ability of the system is effectively enhanced, ensuring the accuracy and stability of communication between the storage subsystem and other devices.

Good scalability: The VMEBUS bus architecture supports modular design, and the XVME-957 storage subsystem can be easily combined and expanded with other VMEBUS bus modules. Users can add storage capacity modules, data processing modules, etc. according to their actual needs, and flexibly build industrial storage systems that meet different scales and functional requirements.

（3） Large capacity storage capability

Despite adopting a diskless design, the XVME-957 still has powerful storage capacity expansion capabilities for a large number of storage subsystems. By integrating multiple storage chips or adopting storage array technology, storage capacity configurations ranging from tens of GB to several TB or even higher can be achieved, meeting the diverse needs of data storage capacity in different industrial application scenarios. Whether it's small-scale industrial data recording or large-scale video surveillance data storage, it can be easily handled.
