interface, its electrical signal is defined by the interface specification, and the quantity depends on the design of the control chip (Controller IC, also including ROC). But the interface or port, all must rely on an entity's manifestation--mainly pin and connectors, can play the role of the connection, and then constitute the data path. As a result, there are interface connectors that are always used in pairs: on one side of the hard drive, HBA, RAID card, or backplane, "bite" with the other

the other hand, the two interfaces can be installed together more firmly.Ii. Understanding detailed installation process of CPU power supply interface Diagram To provide higher and more stable voltage to the CPU, the Main Board currently provides an interface for separate CPU power supply (Four, six, and eight), such: 12 V four-pin power supply interface provided on the motherboard for separate CPU power supply 4-pin, 6-pin, and 8-pin interfaces for CPU power supply The installation method

Or, how many gigabytes of data do we write before we encounter a 1byte read error?Read this article:http://lenciel.cn/docs/scsi-sata-reliability/For different types of hard disks (formerly Enterprise, server, data center-level hard disk with scsi/fiber, commercial, civil level is the IDE, now corresponds to the sas/

PS: The final Exam is finally over, and I finally have time to start running my blog. Some of the lessons in this semester are really very useful, I feel a lot of courses can be written in a very fine technical blog, such as pipeline technology, database of some technology, the examination in the University of the content of "perfunctory" really valuable content to avoid the test, but chasing a lot of the concept is very chicken. No matter how, this summer to myself left a lot of official techni

1.IDE (Integrated drive Electronics, electronic integrated drives), more common. The IDE hard drive has the following three types of transmission modes: PIO (programmed I/O) mode, DMA (driect Memory Access) mode, Ultra DMA (short UDMA) mode.2.SCSI (Small computer system Interface, small computer system interface), is a completely different interface with the IDE (ATA), the IDE interface is the standard interface of the ordinary PC, and SCSI is not specifically designed for the hard disk interfac

The storage design leveraged by the host server architecture has a significant impact on host and guest performance. Storage performance is a complex mix of drives, interfaces, controllers, caches, protocols, Sans, HBAs, drivers, and operating system considerations. Typically, the overall performance of a storage architecture is measured by maximum throughput, maximum IO operations per second (IOPS), and latency or response time. Although these three factors are important, IOPS and latency are m

Iops(Input/output per second) is the input output per second (or read/write count), which is one of the main indicators to measure disk performance. Iops refers to the number of I/O requests that the system can process per second, i/O requests are generally read or write data operation requests. For applications with frequent random reads and writes, such as OLTP (online transaction processing), iops is a key indicator. Another important indicator isData throughput(Throughput) refers to the amou

-control circuit. The front circuit controls the signal induced by the head, the speed regulation of the spindle motor, the head drive and the servo positioning. Because the signal read by the head is weak, sealing the amplification circuit in the cavity can reduce external signal interference, improve the accuracy of operation commands.Disk selection during Enterprise Production The current server market is dominated by SAS, SATA, and SSD disks.Enter

right, here I go. BIOS settings Guide, before you overclock to explain to everyone what is called overclocking and overclocking principle, so that you can better enter the next step of the BIOS setup overclocking!CPU overclocking, its main purpose is to improve the CPU operating frequency, that is, the CPU clock. The CPU frequency is the product of FSB (FSB) and octave (Multiplier Factor). For example, a CPU FSB is 200MHz, the

The topic here is the constrained optimization method, the Lagrange multiplier method (Lagrange Multiplier) and the KKT condition are very important for solving the constrained optimization problem, and the Lagrange multiplier method can be used to find the optimal value for the optimization problem of equality constraint. If there is an inequality constraint, th
