Disk media in the storage area is the most critical device, and all data and information is stored on disk media. The reading speed of the data is determined by the connection interface of the disk media. We used to do data storage through SCSI or SATA interfaces and hard drives. But in recent years a new technology has increasingly been favored by small and medium-sized enterprises and even large enterprises. Is the SAS technology and its correspondi

Opening remarks:
I personally think that the entire SAS protocol family is large, and there are many concepts that are hard to understand. I can only study the actual code at work while reading the protocol in detail. In this way, we can better understand the SAS protocol.
It is the best way to understand the protocol according to the code. Think about all the protocols for data transmission. The communicat
The main types of hard disk interfaces currently available are IDE, SATA, SCSI, SAS, FC, and so on. The IDE is commonly known as the port, SATA is commonly known as the serial port, both of the hard disk is the PC and low-end server common hard disk. SCSI is the abbreviation for "Small computer system dedicated interface", which is the hard disk with this interface. SAS is the SCSI interface of the serial p

Compared with the traditional parallel SCSI interface, SAS is not only significantly increased in interface speed (now the mainstream ultra-320mb/sec SCSI speed is the same, an

As you know, like ata, SCSI is a parallel technology that can connect multiple devices through their respective data channels. Like ata, SCSI is also evolving towards Serial technology, which is SAS (Serial Attached SCSI ).In short, SAS is a new generation of SCSI, which includes some improvements, such as higher transmission speed, better scalability and reliability. Some pe
In practical applications, we often convert wide data (one patient observation) into long data (one patient observation) or long data (one patient multiple observations) into wide data (one observation for a patient), and in R we can use the Reshape2 package. There are two implementations of the SAS: arrays and transpose. This blog post first explains the use of arrays to reconstruct SAS data, and the next

The return code fromCopyCommand is saved in the macro variable copyfile.
