Why are there so many SAS cables Rome is not built in a day, and a norm from the birth to the development of gradually mature is far from the day's work. In the IT industry in particular, any technology is evolving itself, as is the SAS (serial attached SCSI, serial SCSI) specification. As a successor to parallel SCSI, the SAS specification has been out of sight

1:where and if the most essential differences, as well as some small differences1.1:the WHERE statement examines what was in the input page buffer and selects observations before they was loaded in the P Rogram data vector, which results in a savings in CPU operations (where to filter from buffer and then read into PDV)The subsetting IF statement loads all observations sequentially to the program data vector. If The statement finds a match and the statement are true, then the data is processed a

Understanding SAS hard drive

What is SAS? SAS is a new generation of SCSI technology, and the popular Serial ATA (SATA)Hard DiskSimilarly, serial technology is used to achieve higher transmission speeds and improve internal space by shortening the connection lines. SAS is a new interface developed after the parallel SCSI interface. This interface is designed to improve the efficiency, avail

The difference between a SAS hard drive and a SATA hard drive

SAS hard Drive, is a serial connection to the next generation of SCSI technology, the use of serial technology to achieve higher transmission speed, and by shortening the connection line to improve the internal space. SAS is a parallel SCSI interface that develops a new interface. Improves storage system performance, availability, and scalability, and provides compatibility with SATA hard drives. Character

HP d2x00 SAS Storage usage

The most recent project to do Blade server is to use HP D2600 SAS storage. Although it is very simple storage, but because the price is much lower than the P4x00 series SAN storage, it should be said that the scope of use is relatively broad. Of course, some people say this is not comparable, for large enterprises, I fully agree. But for ordinary small and medium-sized enterprises, P4X00 series is a standard SAN, the price is indeed a little expensive
