Abstract
The invention provides a dual-control storage switching control method for SAS and SATA signals by detecting heart beat. The method comprises the steps that an SAS controller 1, an SAS controller 2 and a CPLD chip are arranged in dual-control storage; the working states of the two controller are mutually judged by detecting the heart beat of each other; the two controllers are respectively connected with more than 8 SATA disks; each disk switches the SAS and SATA signals by a multiplexer AAMUX chip; the CPLD chip is connected with and controls more than 16 SATA disks and switches the signals timely by detecting the heart beat of the two controllers via control signals; and the management of the disk arrays that are managed by a host controller out of order is taken over by a host controller that works normally, thus ensuring that the equipment works and runs continuously.
Description
Technical field
The invention provides a kind of Computer Applied Technology, specifically a kind of SAS and SATA signal method for handover control can realize that the hard disk of SAS and SATA signal switching controls and two control storage is taken over switching.
Background technology
SAS has very remarkable advantages in the disk array storage, because the compatible SATA of SAS interface protocol allows to adopt SAS and two kinds of drivers of SATA so the advantage of SAS maximum is its back plate design and protocol interface in same system.Because the SATA hard disk more has the popularity and the price advantage of application, can use the SATA drive that price advantage is arranged in the SAS array stores, even mix and the needed different driving device of coupling related application type, this is a kind of advantage to the user.
Summary of the invention
The present invention is exactly in conjunction with above aspect, realizes SAS and SATA signal switching controls, SAS control can be managed use the SATA hard disk; Provide a kind of hard disk of two control storages to take over the solution of switching simultaneously, utilize two initiatively multiplexers, two console controllers all can be by single SAS of SAS interface independent access or SATA memory device separately, and the hard disks of realizing two control storages are taken over and switched.
Method of the present invention realizes in the following manner, in two control storages, SAS controller 1 is set, SAS controller 2, CPLD chip and AAMUX multiplexer, judge the other side's duty between two controllers mutually by heartbeat detection, two controllers have the SAS interface more than 8 respectively, each SAS interface of controller respectively connects an AAMUX multiplexer, and by a corresponding SATA hard disk of this AAMUX multiplexer connection, the CPLD chip detects the heartbeat of two controllers in real time, by the switching of AAMUX multiplexer control SAS and SATA signal, it is as follows to detect controlled step in good time:
1) when SATA hard disk duty just often, two control softwares can be sent out control signal corresponding and give CPLD, CPLD control AAMUX chip carries out the switching of SAS and SATA signal, two control softwares send the multiplexer AAMUX chip that control signal corresponding administers for SAS controller 1, SAS controller 2 separately, and multiplexer AAMUX chip switches two controllers and administers being connected of hard disk separately;
2) when the dual controller heartbeat detection is found side's operation irregularity, two control softwares transmit control signal to CPLD, close being connected of unusual controller and multiplexer AAMUX chip its administration, and being connected of that open normal controller and multiplexer AAMUX chip unusual controller administration, make normal controller be connected to the multiplexer AAMUX chip of unusual controller administration, hard disk is worked on.
The invention has the beneficial effects as follows: in two control storages, owing to failure and other reasons causes a console controller can't operate as normal, thereby the disk that causes its management can't continue to use, adopt method of the present invention can realize the hard disk adapter switching of two control storages, the hard disk array of out of order host computer control management switched to the console controller of operate as normal manage, just can guarantee equipment non-stop run and operation.
Description of drawings
Fig. 1 carries out the structural representation of two control method for handover control by detecting heartbeat to SAS and SATA signal.
Embodiment
By detecting heartbeat SAS and SATA signal are carried out the following detailed explanation of two control method for handover control do to of the present invention with reference to accompanying drawing.
SAS has very remarkable advantages in the disk array storage, the SATA hard disk has the popularity and the price advantage of application, and the present invention is exactly in conjunction with both advantages, realizes SAS and SATA signal switching controls, the SAS controller can be managed use the SATA hard disk.
As shown in Figure 1, in two control storages, two SAS controllers are arranged, judge the other side's duty between 2, two controllers of controller 1 and controller by heartbeat detection mutually.Be connected to 16 SATA hard disks altogether in two control storages, each hard disk is received on two controllers by an AAMUX chip (multiplexer can carry out the switching of SAS and SATA signal).Have a CPLD chip to connect these 16 of controls, and CPLD there is a control signal to receive the heartbeat detection of two controllers.
If when connecing the SATA hard disk, two control softwares can be sent out control signal corresponding and give CPLD, and CPLD control AAMUX chip carries out the switching of SAS and SATA signal.
Embodiment
For better realizing two control storages, increase work efficiency, during normal operating conditions, 8 hard disks of each controller management, (as controller 1 management hard disk 1-8, controller 2 management hard disks 9-15), two control softwares are sent out control signal corresponding AAMUX chip, then AAMUX chip 1-8 is turned off controller 2 and they be connected, and AAMUX chip 9-15 is turned off controller 1 and they be connected.
When the dual controller heartbeat detection is found side's operation irregularity, as controller 1 operate as normal, when finding controller 2 operation irregularities, two control softwares transmit control signal to CPLD, turn off being connected of controller 2 and AAMUX chip 9-15, and open being connected of controller 1 and AAMUX chip 9-15, make controller 1 take over hard disk 9-15, work on.
Claims (1)
1. one kind is carried out two control bank switching control methods to SAS with the SATA signal by detecting heartbeat, it is characterized in that in two control storages, SAS controller 1 being set, SAS controller 2, CPLD chip and AAMUX multiplexer, judge the other side's duty between two controllers mutually by heartbeat detection, two controllers have the SAS interface more than 8 respectively, each SAS interface of controller respectively connects an AAMUX multiplexer, and by a corresponding SATA hard disk of this AAMUX multiplexer connection, the CPLD chip detects the heartbeat of two controllers in real time, by the switching of AAMUX multiplexer control SAS and SATA signal, it is as follows to detect controlled step in good time:
1) when SATA hard disk duty just often, two control softwares can be sent out control signal corresponding and give CPLD, CPLD control AAMUX chip carries out the switching of SAS and SATA signal, two control softwares send the multiplexer AAMUX chip that control signal corresponding administers for SAS controller 1, SAS controller 2 separately, and multiplexer AAMUX chip switches two controllers and administers being connected of hard disk separately;
