For a period of decades spanning, disk drive and the system is connected via a parallel bus interface. This provides many benefits for users of this technology, but also a large number of limitations. For companies looking for interfacing solutions, ideal options are not available.
However, with significant progress has been carried out in recent years, new interface technology has been available and has changed this domain landscape. These two famous examples are attachments of the Serial (SATA) advanced technology, and the attached SCSI series (SAS).
Many users can take advantage of this series of new solutions to fit their exact requirements, whether they are in business or need to use technology for other reasons. The benefits of the attached serial SAS are very impressive, but for a more complete description, it is useful to compare technology with its predecessor.
The earliest interface is a small computer system interface (SCSI). The development of this began in the late 1970s and the interface became completely available in the 1980s. It serves as a hard disk interface, and even after many revisions and improvements, still generally fulfill this function today.
In addition to its role as a hard-disk interface, SCSI is often used to connect various other peripheral devices, including printers, scanners, and CD drives. There are many advantages to this technology, which has many loyal users, but there are shortcomings that might mean that it is not an ideal solution for everyone.
One of the main negative factors that presents itself when it comes to this specific interface is that the parallel cable limits the length of the cable and data transfer speed. This can greatly influence efficiency and usability. However, this problem has been aimed at the appearance of SATA and SAS.
The first significant advantage of SAS Over SCSI is that it is fully compatible with SATA drives. SAS’s ability to support this device is a key factor in the use and application of this technology, and devices that offer this double function are increasingly mainstream. But yet, SCSI cannot be used this way.
SATA is an important factor because it uses a high-speed serial bus than a parallel bus low speed SCSI. SAS applies this technology to provide new and better technology standards, produce interfaces that are faster and more efficient.
The integration of these two free technologies can bring big profits for users. By implementing SAS infrastructure, it is claimed that users can save a large amount of money. Because it supports SATA, new drives can be added to existing infrastructure when needed, and the system scale can be easily adjusted according to the demand for capacity building.
This is different from other infrastructure that does not have this flexibility in terms of scalability. This can allow users to just ‘upscale’ when needed, without investing in a completely new system to meet their requirements. This can save not only at costs, but at the time and effort invested in integrating a completely new system.
The attached SCSI series also offers increased performance in other areas compared to its predecessor. The drive benefits from a point-to-point connection, which means there is no bandwidth sharing between several devices on the bus together. This contrasts with previous technology, where bandwidth is divided between the device.
Compared to SCSI, SAS can also claim data transfer speeds. It can range from 3 to 6 GB per second, which is much higher than before. This shows greater efficiency and can mean significant benefits for users.
When deciding which interface architecture is applied, various options are available on the market. The attached SCSI series is one of the options that offers many improvements in previous technology, and can offer better usability, C
