relatively simple, Standby controller needs to monitor the active controller, once the active controller has found a problem, You can take over the role of this controller and continue to provide storage services to users. Active-standby enhances system availability, but does not lead to increased throughput. Active-active not only enhances system availability, but also improves storage-system performance. On the implementation, the latter is a lot more complex, not only to solve the problem of

manufacturers of DSP chips differ. In terms of outward addressing, it is logically the same, because the reasons for external pins are generally achieved through the corresponding spatial selection. is essentially the same truth. 4. The structural differences between the improved Harvard structure and the Harvard architecture Compared to the von Norman structure processor, the Harvard structure processor has two distinct features:(1). The use of two separate memory modules to store instructions

There are several ways to use1. Single domain: There is only one connection path from host to disk cabinet, that is, only one I/O module is used.2. Dual domain: There are two connection paths from the disk cabinet to host, that is, two I/O modules are used. This usage provides full redundancy, any single point of the SAS cabl

. After the scsi bios is started, a picture is displayed. If the SCSI hard disk is found, the hardware is correctly installed! External hard drive: External SCSI hard drive has many advantages, such: 1. If you do not need a hard disk, you can turn off the power to reduce unnecessary work on the hard disk. 2. Easy to disassemble and install. You do not need to open the host chassis. 3. The ID can be switched directly on the chassis without the need to plug or remove jumper from the hard

PHP fgetcsv Definition and usage The PHP fgetcsv () function reads a line from the file pointer and resolves the CSV field. Like PHP fgets (), the difference is that PHP fgetcsv () parses a read-in row and finds a field in CSV format, and then returns an array containing those fields. Fgetcsv () returns FALSE when an error occurs, including when the file ends. Note: PHP fgetcsv () operation is binary safe from php 4.3.5. Grammar Fgetcsv (File,length,separator,

and HTML tags contained in strings. To filter out any special tags, you can include them in the allowable_tags string. When reading files written by others or files containing user input, you can use the fgetss () function for operation security considerations. Allowing unrestricted HTML code to appear in a file may corrupt your well-designed format. Allowing unrestricted PHP code to appear in a file may allow malicious users to control the server in an almost free way. The fgetcsv () function

Static reactance DisturbanceIdeally, our system is a hollow and airtight metal box, according to the theory of electromagnetic field, the outside of any static power supply can not affect the inside of the box circuit operation. However, such a system is of little practical significance. An actual system must include an external interface (i.e., it is impossible to seal). An actual (metal-cased) system should be able to put the el

Learn a new php function (2) fgetcsv ()/fgets (), fgetcsvfgets Reading and Writing files is a common action. There are thousands of functions for reading files, which are complex and simple. The most common and convenient operations are file_get_contents () and file_put_conents (). You do not need to open or close a file.But when reading large files, file_get_contents () will read all the content into the memory, resulting in memory overflow. It is best to read it cyclically by row. Fgetcsv ()
