Abstract

The invention provides a hard disk backboard and a control panel, and the hard disk backboard comprises a hard disk connection port which is connected with at least one hard disk; the integrated circuit bus communication interface is used for being connected with a main board; one end of the control chip is connected with the main board through an integrated circuit bus communication line insertedinto the integrated circuit bus communication interface, the other end of the control chip is connected with the hard disk connection port, communication transmission signals are received from the main board, and corresponding hard disk signal lamps are controlled according to the communication transmission signals; wherein the communication transmission signal is generated by analyzing the mainboard according to the received serial universal input / output signal. According to the invention, a CPLD (Complex Programmable Logic Device) on the HDD back plate is removed, and only one control chip(PCA9555) is added, so that the design is simplified, the materials are reduced, the cost is reduced, the occupied area of a PCB (Printed Circuit Board) is reduced, and particularly, the problem of wiring of the back plate is fundamentally solved through the 1HDD back plate and the 2HDD back plate.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to the technical field of server backplanes, specifically a hard disk backplane and a control board. Background technique [0002] HDD, the abbreviation of Hard Disk Drive, is the English name of the hard disk drive. The most basic computer memory, the computer hard disk C disk and D disk that we often say in our computers are disk partitions, all of which belong to the hard disk drive. At present, the common disk capacities of hard drives are 80G, 128G, 160G, 256G, 320G, 500G, 750G, 1TB, 2TB and so on. Hard drives can be divided into 3.5 inches, 2.5 inches, 1.8 inches, etc. according to volume; 5400rpm / 7200rpm / 10000rpm according to rotation speed; PATA, SATA, SCSI, etc. according to interface. PATA and SATA are generally desktop applications with large capacity and relatively low price, suitable for home use; while SCSI is generally high-end applications such as servers and works...
