The SCSI development technology has made a revolution in the way the devices communicate within computer systems. Over time, SCSI has evolved into various forms, with parallel SCSI being traditional technology and connected SCSI (SAS) that represents modern repetition.
While both criteria share a common basis, they differ greatly in terms of performance, expansion and design. Understanding the differences between parallel SCSI and SCSI Serial (SAS) companies and individuals make enlightened decisions regarding the appropriate storage solution for their needs.
Parallel SCSI basics
In essence, the parallel SCSI connects multiple devices to one bus through a parallel connection, allowing data to be transferred simultaneously through multiple wires. The ability to connect devices such as printers, scanners and external drives made SCSI parallel to a multi -use and reliable option for many computing environments during their time.
The parallel nature of this technology has increased restrictions that have become increasingly difficult, as it demanded a higher performance. Parallel SCSI is struggling with problems such as signal noise and limited cable lengths, which restrict device mode rates and data transfer rates. While these issues have improved with many improvements over the years, the ultimate appearance of SCSI made SCSI parallel to less competitive.
Submit SCSI The Series Series (SAS)
SCSI Series (SAS) was presented as a development of traditional SCSI standards, the treatment of many performance restrictions and expansion in its predecessor. SAS uses serial communication protocol from point to point.
This design choice greatly reduces signal overlap and facilitates data transmission speeds much higher than parallel SCSI. SAS supports up to 22.5 GB per second in its last generation, making it perfectly suitable for modern applications that are storage.
Another feature of SAS is the ability to expand. While the parallel SCSI supports a limited number of devices on a shared bus, SAS allows the connection of thousands of devices through their use of the expansion. This expansion is made of special value for institutions that require huge amounts of storage.
Performance and practical applications
One of the important discrimination between the parallel SCSI and SAS is its ability to perform it. SAS superior data transmission speeds and lower cumin make a better option for high -performance environments, such as data centers and server farms.
For example, SAS drives are usually used in institutions systems where rapid access to large data groups is required. On the other hand, the parallel SCSI, though largely old, is still being used for old systems that require compatibility with old equipment.
Choose the correct technology
For most modern applications, SAS is the clear option due to its advanced performance, expansion and reliability. Parallel SCSI, despite its historical importance, is primarily viable for use in old environments where the upgrade to the latest standards is not possible. In such cases, the SCSI adapter is a practical solution to connect old SCSI devices to modern systems, ensuring continuous functions without a complete repair process.
The selection between parallel SCSI and SCSI SES (SAS) allows companies to improve their storage solutions effectively. Consider your system requirements, as well as strengths and restrictions in each technology.
