Description
Technical field
This utility model relates to computer hardware technology field, particularly relates to a kind of storage extension cabinet.
Background technology
In recent years, fast development along with new techniques such as cloud computing, mobile, social networks and big data four main trend, either enterprise or individual are increasing to storage device platform requirement, the data needing storage gets more and more, the most increasing to the capacity requirement of storage server, then storage extension cabinet is arisen at the historic moment.Storage extension cabinet is connected with main cabinet storage by SAS, has both facilitated systematic unity to manage, again can be with relatively low cost increase memory capacity at double.
But current storage extension cabinet also has several drawback:
(1) storage extension cabinet internal connection high-speed cable connects, with high costs and trouble when assembling；
(2) every kind of different types of storage extension cabinet needs to use different panels and hard disk backboard, designs loaded down with trivial details and is unfavorable for that scale is disposed；
(3) connecting with cable inside storage extension cabinet, because the loss of cable long range propagation, general storage extension cabinet can only extend 3 grades just because signal attenuation cannot the most down extend.
Utility model content
For above technical problem, the utility model discloses a kind of storage extension cabinet, it is designed by a kind of new system architecture; both improve the reliability of system; allow again system more easily scale application can assemble simultaneously with cascade more stages extension cabinet, reduce cost.
To this, the technical solution of the utility model is:
A kind of storage extension cabinet, it includes cabinet, power module, hard disk backboard, Signals Transfer Board and Power conversion board it is provided with in described cabinet, described power module is connected with Power conversion board, described Power conversion board is connected by golden finger with hard disk backboard, and described Signals Transfer Board is connected by golden finger with hard disk backboard.
Using this technical scheme, all use PCB design to substitute high-speed cable and connect between extension storage cabinet inside, system assembles is convenient, has shock resistance, and the relatively high speed cable of cost is relatively low.Being connected by other keyset of golden finger by hard disk backboard, can support 2U/3U/4U extension cabinet by Signals Transfer Board and Power conversion board simultaneously, convenient purification scale is disposed.
As further improvement of the utility model, described hard disk backboard includes Expander chip.Use this technical scheme, Expander chip on hard disk backboard is storage and the higher management of whole extension cabinet, the SAS signal extension come from prime is gone out multiple hard disk signal and the SAS of next stage extension cabinet by it, it is responsible for monitoring the voltage/current/power of whole extension cabinet simultaneously, and controls rotation speed of the fan and other LED.This hard disk backboard both can be placed in main cabinet with cabinet storage of deciding, it is also possible to is used in extension cabinet.When being used in main cabinet, whole system controls to be responsible for by mainboard, and backboard Expander is only responsible for expanding hard disk；When being used in extension cabinet, system control information transmission then by hard disk backboard, on Expander be responsible for.
As further improvement of the utility model, described hard disk backboard is 2U, 3U or 4U hard disk backboard.Use this technical scheme, described Signals Transfer Board can be applied in combination with different hard disk backboards from Power conversion board, for any level 2U/3U/4U extension cabinet.
As further improvement of the utility model, described power module is positioned at the rear side of described cabinet, and described hard disk backboard is positioned at the middle part of described cabinet, and described Power conversion board is between described power module and described hard disk backboard.
As further improvement of the utility model, described Power conversion board includes the first connection limit being connected with described power module, and the second connection limit it is connected with described hard disk backboard, described first connects limit is connected the limit the 3rd connection limit connection formation by side with second, described first connects limit, the second connection limit and the 3rd connection skirt city U-shaped, and described first connects the thickness not less than fan module of the distance between limit, the second connection limit.Using this technical scheme so that structure is compacter, and achieve untethered, system assembles is convenient, has shock resistance, and the relatively high speed cable of cost is relatively low.
As further improvement of the utility model, described Signals Transfer Board includes Redriver chip, Mini SAS interface, serial ports, LED light and power knob.Wherein, Redriver chip, carry out the SAS signal come from upper level strengthening and drive and after signal postemphasises, pass to the Expander chip of hard disk backboard again, and this Redriver is controlled by I2C by Expander chip, significantly can improve signal quality according to the differently configured parameter of different system track lengths, the multi-tier cascade for extension cabinet provides key foundation.Use this technical scheme, by the way of increasing Redriver chip on Signals Transfer Board, increase the driving force of every grade of extension cabinet SAS signal, so that extension cabinet can expand to more than 5 grades.
As further improvement of the utility model, described Signals Transfer Board includes switching on and shutting down switch and system reset circuit.Because extension cabinet is without mainboard, the mode of d type flip flop is used to realize switch and reset.
As further improvement of the utility model, described Signals Transfer Board includes HW Monitor IC chip, and described HW Monitor IC chip is connected by I2C with Expander chip.Using this technical scheme, described HW Monitor IC chip is used for detecting voltage, fan, power etc., then by I2C, relevant information is given to Expander chip.
Compared with prior art, the beneficial effects of the utility model are:
First, use the technical solution of the utility model, both improve the reliability of system, allow again system more convenient can carry out scale application simultaneously assemble with cascade more stages extension cabinet.
Second; use the technical solution of the utility model, hard disk backboard is designed to compatible main cabinet and the mode of extension cabinet, and is connected with other keyset by golden finger; in extension cabinet, two pieces of keysets of new design can support 2U/3U/4U extension cabinet simultaneously, facilitates scale and disposes.
3rd, all use PCB design to substitute high-speed cable between extension storage cabinet inside and connect, system assembles facilitates shock resistance good, and the relatively high speed cable of cost is low；And the driving force of every grade of extension cabinet SAS signal can be increased, so that extension cabinet can expand to more than 5 grades by the way of increasing Redriver chip on PCB.
