The company, every day have more consideration to contingency solutions that might allow the recovery of a server which fails. The automatic geographic cluster, is one solution integrates with remote hardware copy cluster environment so that the disaster failover process is fully automatic. In this case, would be a solution designed for a high service criticality would require the implementation of an extended SAN network, as well as the third copies mechanisms necessary for the restoration of data logical disaster in tending to zero times. The cluster will be distributed between a main centre and another alternative, with a node access to each storage system. A node accesses the main disks and the other has the possibility of accessing the remote copy. Disaster remote disks on the second node of the cluster are prepared automatically during the failover process and from this service is lifted.

Since the process is automatic and does not require manual intervention, the switching time is quite small, about 5 or 10 minutes depending on the applications that are running. With this solution and in a situation of total loss of communications between the two centres there is the risk of Split Brain, i.e. that both cluster nodes continue to operate independently and the information is corrupted. To avoid this possibility, consider leaving the failover in manual mode where all communications, servers and storage systems are lost. Via this solution is achieved be tolerant physical disaster, those applications that have data, with close to zero response thresholds. Disaster logical, remote copy unusable, since as this type synchronous, all changes are replicated to the remote Center, including the corruptions of databases or deletion of information. These one of the different alternatives of the numerous recovery strategies. From Audea want to remind you that the best way to prevent a penalty or damage to our information systems, is to comply with all technical and legal requirements of the security of the information.

Appropriate Dryer

When the user purchasing the drying equipment (dryer machine), it is necessary to select them, the following is the several details need to pay attention in the selecting process of dryer (dryer machine): First, corporate site visits We should first examine the drying equipment manufacturers, observed the attitude of the Factory, on this basis, we can get a preliminary understanding and the productive capacity of the plant environment. Learn whether this plant have equipments or not, whether Han materials laboratory experimental data or not, the experimental results of materials. We should seriously listen to the phenomena of the factory report, understand its manufacturing capacity, whether the drying equipment manufacturers meet the requirements means processing, listen to the processing method type statement of the drying equipment manufacturers. Then, see whether the enterprise have an existing production site or not Level of drying equipment manufacturers depends to some extent on the performance of its work, under normal circumstances, the more work equipment manufacturing capacity, the stronger performance their equipment manufacturing abilities, because the manufacturing equipment technology can make the equipments more excellent. If the manufacturer is the first manufacturer of this model, then the user must be cautious, the serious argument to its technology maturity is necessary.

As to the credibility of the enterprise, we can also get from its customers. Nowadays, the society after-sales service is an important indicator to measure products. The drying equipments are required to regularly maintenance, in the process of operating the machine, some problems that are different to solve may sometimes appear, whether some wearing parts have generality or not, whether the plant can provide users with permanent technology consultation, removals or not, these are all questions need to take into account when selecting the dryer machine manufacturers. We need to inquire the dryer machine manufacturers and their users to learn the enterprise credit and their current after – sale situation, thus can avoid the unnecessary economic loss efficient. Finally, examine the drying effect of the same or similar materials, if the further investigation are carried out, it is best that the drying equipment manufacturers can provide the same material drying experience, so that the credibility of this project can be efficiently increaser. It is proved that carry out the situ experiments, the situ testing equipments are important basis to increase the confidence of customers purchasing. We hope the above suggestions are helpful.
