Description
Technical field
The present invention relates to server technology field, it is related to a kind of hard disk Active lamp lighting optimization system and method.
Background technique
Nowadays, server industries reach its maturity, and server product is also to emerge one after another, need of the client for server
It asks and has been not limited solely to store mass data, performance is stablized etc., but start to focus on information security, application is safe,
And the convenience of application.
Recent client is just to the storage medium of server --- and hard disk proposes new demand.Since the hard disk having is supported
Hot plug, some hard disks do not support hot plug, and in view of the safety in the case of hard disk hot plugging, client is proposed, newly
Server product be required to on backboard hard disk carry out it is independent up and down electric control, when needing to carry out hard disk extraction,
It first by the dump of hard disk, is then extracted, after hard disk insertion, hard disk is powered on, can solve hard disk in this way can not
Hot plug problem, while also avoiding plugging hard disk, increase safety.
In existing technical solution, two Efuse are added to for each hard disk, control the 5V and 12V of hard disk respectively
Power supply, the enable signal of Efuse is connected to the CPLD of backboard, by CPLD control Efuse it is enabled whether, and then control corresponding hard
The power-on and power-off of disk, and the power-on and power-off of hard disk instruct, then are the CPLD being handed down to by the BMC on mainboard by I2C on backboard, such as scheme
Shown in 1.
In generic server backboard lighting demand, Active lamp is used to refer to disk state, when hard disk is normally in place,
Active lamp is always on, and when hard disk is read and write, Active lamp is flashed with the frequency of 4Hz, and hard disk power down or it is not in place after,
Active lamp extinguishes.In existing scheme, specially treated is not carried out to Active lamp, after hard disk power-off, it is believed that Active lamp
It can automatic distinguishing.
In the above scheme, it is hard to have fully achieved individually control for the hard disk power-on and power-off control instruction issued by BMC
The power-on and power-off of disk.But either customer demand or when R & D design all has ignored a bit, that is, the Active of hard disk
Lamp (green light) source is to pass to hard disk by light-guiding pillar on hard disk backboard, and the light on and off of lamp are externally showed by hard disk；And on backboard
Active lamp be to be controlled by CPLD, and driven by the 3.3V electricity on backboard, and 3.3V electricity is by the control of CPLD, also with
It is unrelated whether hard disk powers on.No matter hard disk powers on or lower electricity, Active lamp are still normally lighted, and can not be confirmed by phenomenon
Whether hard disk really descends electricity.Accordingly, it is considered to whether can be on the basis of not changing existing hardware structure, to Active lamp
Lighting mechanism optimizes, and can correctly reflect the electricity condition up and down of hard disk.
Summary of the invention
