An ultra SCSI device refers to a type of peripheral device that utilizes the Small Computer System Interface (SCSI) technology, which facilitates data transfer between a computer and the device at a higher speed and efficiency than the earlier versions of SCSI. With its enhanced capabilities, an ultra SCSI device allows for faster data transmission, greater data throughput, and increased device support.
The term "ultra" in ultra SCSI signifies an advancement over previous SCSI technologies, employing a significantly faster data transfer rate. The ultra SCSI standards include variations like Ultra SCSI-2, Ultra Wide SCSI, and Ultra2 SCSI, each offering different features and capabilities. These devices are commonly used in high-performance computing environments, such as servers and workstations, where efficient data transfer and processing are critical.
Compared to older SCSI devices, ultra SCSI offers faster data transfer rates, typically ranging from 20 to 40 megabytes per second (MB/s), depending on the specific variant and device configuration. It also supports a larger number of devices on a single SCSI bus, which enables the connection of multiple peripherals simultaneously.
Ultra SCSI devices use a parallel interface that employs a wider cable and connector to transmit data with higher efficiency. They can be used to connect various peripherals, including hard disk drives, tape drives, optical drives, and high-speed scanners. Additionally, ultra SCSI devices can be backward compatible with earlier SCSI standards, allowing them to work with older SCSI devices and systems.
In summary, an ultra SCSI device is a peripheral device that utilizes advanced SCSI technology to achieve higher data transfer rates, increased throughput, and improved device compatibility. It is an essential component of high-performance computing systems that require efficient data handling and can connect to various peripheral devices.
