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. Located in the path: C: "Books" Learning under the text file MyData.txt, its data to open, the form is as follows:M 50 68 155F 23 60 101M 65 72 220F 35 65 133M 15 71 166The code to read into the SAS is as follows:Data demographics;InFile ' C: "Books" Learning "MyData.txt";Input Gender $ age Height Weight;RunThe symbol $ indicates that the variable gender is a one-character variable. To check that the read-in file is correct, you can view its observ

compatible with the PATA device by using a multi-purpose chipset or serial-parallel converter. Because SATA and PATA can use the same drive, you do not need to upgrade the operating system or perform other changes. 5. You do not need to set the jumper of the Master/Slave disk for Sata. The BIOS will number it in the order of 1, 2, and 3. This depends on the SATA connector to which the drive is connected (easy to install ). However, the IDE hard disk must be configured with a jumper to set the

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

SAS interface technology can be backward-compatible with SATA. Specifically, the compatibility of the two is mainly embodied in the physical layer and the protocol layer compatibility. In the physical layer, the SAS interface and SATA interface are fully compatible, SATA hard disk can be directly used in the SAS environment, from the interface standard, SATA is a

Intel S5000VSA (SAS) motherboard setup RAID stepsI recently personally installed a server, with the Intel S5000VSA 4DIMM motherboard, because in the installation process did not notice some details, so in the installation encountered some problems, and then after everyone's research and discussion, finally successfully solved these problems, in order to accumulate experience, Also in order to allow other colleagues to avoid the network, save time, spe

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

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

CPUTime: The amount of theProcessing Unit (CPU) uses to perform requested tasks such a s calculations, reading and writing data, conditional logic, and iterative logic. CPU time was measured when data must was processed in the program data vector.I/o:A measurement of the read and write operations that is performed as data and programs are Copied from a storage device to memory (input) or from memory to a storage or display device (output).1: Use SAS

Disk back panel: Eclectic In the tower server where the rack server or the hard drive slot is higher, the SAS Hba/raid card is generally not connected to the hard drive directly with the SAS cable, but through the disk backplane to facilitate the hard drive Plug and unplug. Disk Backplane is also a typical internal connection application, one side of the hard drive, the other side even Hba/raid card. Drive

Recently, the SAS code of the old system in the calculation process, there are less data, I passed a few times to check the code, or did not find the problem. Finally, with the help of a senior colleague, I found the cause of the problem, but in retrospect I still feel that I am not careful enough and how to debug the SAS code is not proficient, description as follows: The code is mainly the following code

In general, we will use Excel to statistical test results, in addition to Excel, there are SAS and other software, but also can be statistical test results, I am also a beginner of SAS, now I would like to introduce you to the simple use of SAS, with my constant learning statistics knowledge, 　　 I would also like to delve into the features of these statistics sof
