Abstract
The invention discloses a port state monitoring method for a fiber channel switch. According to the port state monitoring method, all port states of the fiber channel switch are independently monitored, after the port state is collected for each port, the collected port states are compared with previous port states, and different levels of alarms are transmitted according to comparison results. In the process of monitoring all the port states, as the threshold values and collecting frequencies of all the port states are adjusted in real time according to change conditions of the port states, it is guaranteed that all the port states are effectively monitored, and network resources are saved to the maximum degree. The working states of the fiber ports serve as monitoring correspondences, and therefore the existing problem of monitoring blind spots is effectively solved.
Description
Technical field
The present invention relates to storage area network technical field, relate in particular to a kind of port status method for supervising of fibre channel media.
Background technology
Along with scientific and technological development, the increase of amount of information, it is more and more huger that External memory equipment becomes, and people are also more and more higher with the requirement of reading speed to data storage.Particularly in recent years, along with the frequent degree of continuous increase and the network application of enterprise network data, increasing enterprise starts to build own vulgar network and meets the needs that growing data are stored property.
Storage area network (Storage Area Network, SAN) is a kind of simple storage application and network technology new technology of having combined, and its appearance has met people's requirement with reading speed to data storage.SAN is the special optic fibre channel network that connects memory device and server, by supporting that server, optical channel card (network interface card), fibre channel media (or hub) and the optical-fibre channel storage device of optical-fibre channel are formed.Technologically speaking, most important three parts of SAN network are exactly: equipment interface (as small computer system interface, optical-fibre channel, management system connection etc.), connection device (switch, gateway, router etc.) and communication control processor (as IP agreement and SCSI agreement etc.).These three assemblies are added additional memory device and server (comprising a network management server), form a SAN system.
Adopt fibre channel media that storage system is connected with server, high speed data transfer and data sharing, LAN data backup and storage can be provided.Fibre channel media (Fiber Channel switch, FC switch) is the core of SAN, and its running status is directly connected to the running status of whole SAN.In order to improve the reliability of SAN, the port status of can Adoption Network management server monitoring in real time fibre channel media, according to every port status of fibre channel media, thereby send various alarms, thereby realize the fault pre-alarming of storage area network and fault locating analysis.
In existing fibre channel media method for supervising, the general state information that all gathers fibre channel media by each certain time interval of snmp protocol, is analyzed and is obtained the early warning information of fibre channel media and send alarm by SNMP trap according to flow information.The method can realize the monitoring to the running status of fibre channel media to a certain extent.But conventionally gather the acquisition strategies underaction of the state information of fibre channel media, adaptive ability is poor, the alarm signal that just remains unchanged (unadjustable) after setting sample frequency (time interval of collection) and send is single, and in practical application, situation is complicated and changeable.
Summary of the invention
Deficiency for the method for supervising of existing fibre channel media, the invention provides a kind of port status method for supervising of fibre channel media, this method for supervising can self adaptation practical situations, adjusts in real time frequency acquisition and metrics-thresholds, completes alarm.
A port status method for supervising for fibre channel media, comprising:
(1) by one day, be divided into several time periods, and set the frequency acquisition of the port status of each port in each time period;
(2) for any one port, according to the frequency acquisition of setting, gather the state of fibre channel media, and a upper port status of the port status of each port collecting and this port is compared, and send corresponding alarm according to comparative result.
Alarm of the present invention can be voice reminder, also can point out for message box, and can be also sound and light signal prompting etc.
In the port status method for supervising of fibre channel media of the present invention, monitor several port statuss of optical fiber switch, and the monitoring of each port status is independently carried out, first according to practical application request, set respectively frequency acquisition and the metrics-thresholds of each port status, data acquisition server independently gathers each port status according to the frequency acquisition of each port status, and compare with corresponding metrics-thresholds, according to comparison result, send corresponding alarm.Wherein, data acquisition server gathers the state information of fibre channel media by snmp protocol.
The port status once collecting before a upper port status of each port status refers to.In practical application, need each port that initial port state is set.For the port status collecting for the first time, the initial port state of setting is a upper port status of this port status.
Described port status comprises No. WWN, the equipment (World Wide Name) of transmission speed, operating state and the connection of fiber port.
Described operating state is for having light state or without light state.
Have light state to refer to that this fiber port has optical signal transmission, this fiber port of unglazed state representation is without optical signal transmission.When without optical signal transmission, may be due to outside without connection device or this fiber port and external connection apparatus without optical communication.For optical fiber switch itself, fiber port has light or the unglazed normal condition that all belongs to, and therefore, when external connection apparatus breaks down or be connection external equipment, self detects and can not give a warning, thereby occurs monitoring blind spot.In the present invention, by the operating state of fiber port (have light state and without light state) is added in monitoring, effectively overcome this monitoring blind spot.
The frequency acquisition of the port status of the different port in described step (1) is also not quite similar with the difference of time period in one day.
The frequency acquisition of the port status of the same port in described step (1) is also not quite similar with the difference of time period in one day.
Under practical situations, different fiber port (port) is in the accessed frequency difference of crossing operation of different time periods, and the identical frequency acquisition of unified employing, easily causes the wasting of resources.Therefore according to application demand, when frequent operation, the frequency acquisition of setting is relatively high, operates when relatively less, and the frequency acquisition of setting is relatively low.Accordingly, when data acquisition server gathers the state information of optical fiber switch in described step (2), first determine the time period under the time point of this collection, using the frequency acquisition of frequency acquisition corresponding to described time period as this collection.
As preferably, for each port, at the same time section in, if the continuous several times of the port status collecting are constant, adjusting corresponding frequency acquisition is 1/3～1/2 of former frequency acquisition.
As preferably, for each port, in section at the same time, if the port status collecting changes several times continuously, adjust corresponding frequency acquisition and be former frequency acquisition 2～3 times.
In a period of time, the frequency acquisition that the constant or continuous variation of the continuous several times of port status illustrates setting is unreasonable, need to adjust, after adjustment, at the same time section in, with the frequency acquisition after adjusting, gather this port status, and continue to adjust frequency acquisition according to the situation of change of port status simultaneously.Conventionally setting is for 3～6 times adjustment cycle, if 3～6 times continuous constant, can think that current frequency acquisition is relatively high, forms network resources waste, therefore reduces frequency acquisition; If port status changes 3～6 times continuously, think that current frequency acquisition is too low, need further to improve frequency acquisition.
The port status method for supervising that a kind of fibre channel media is provided of the present invention, in this method for supervising, independently each port status of fibre channel media is monitored, in the monitor procedure of each port status, according to the situation of change of port status, adjust in real time threshold value and the frequency acquisition of each port status, guarantee each port status of effective monitoring and can farthest save Internet resources, and the operating state of fiber port is corresponding as monitoring, effectively overcome existing monitoring blind spot.
