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.
The first half of the year, to respond to the complex economic situation building materials machinery industry took its efforts to accelerate the pace of industry restructuring. The industry has maintained a rapid development whole. It reveals the following characteristics: 1. Production and marketing of high-speed growth: Building material machinery industry in the first half had an increase of more than 30% of the total industrial output value and sales value. 2 Unequal development of the sub-sectors: Building materials machinery sub-sector, the rapid development in the first half of the concrete machinery products, has contributed to the rapid development of the industry. Wall materials machinery, ceramic machinery and stone machinery are still in a rather optimistic situation and situation is relatively good industry, cement and the glass machinery are face with downward pressure.
Some basic knowledge of cement grinding will be mentioned here. Cement grinding is not only the last process in the cement equipmentmanufacturing process but also the most power consumption process. Its main function is to grind cement clinker(gelling agent, performance) pipes tuning) to appropriate particle size (fineness, surface area), form a certain particle size distribution, increase the hydration area and accelerate the hydration rate to meet the requirements of cement slurry condensation and sclerosis. 3 Export delivery value of the sharp rebound: The first half of the year, enterprises increase to explore the international market, accelerate the pace of going out. The industry exports have resumed its growth, and export delivery value of year-on-year increase of 100%.
4 High receivables to be gain: From January to May, the industry trade receivables up to 10.6 billion yuan, a year-on-year growth of 45% increase compared to the same period last year increased by 8 percentage points. The pressure of building materials and machinery enterprise funds advance loan recovery difficult. In addition, the financial costs of rapid growth, 1-year-on-year increase of 20.1% in May, including interest expense year-on-year increase of 30.9%. Development vitality of stronger during the first half of the state-owned enterprises, state-owned holding enterprises in building material machinery industry output value up 67.2% year-on-year, showed strong development vitality.

Advanced crusher helps transform coal Coal industry Governor a major position in China s energy structure; It determines the building ideas toward the development of large coal mines, so construct large opencast coal mine will be the focus of China s energy construction projects. The state s supporting to mining resources bring a good market opportunity for the major mining machinery enterprises, so many domestic crusher equipment manufacturers are striving to get a cake in the mine construction, Hongxing Mining Equipment Co., Ltd. and come to the fore with the salts relying on its excellent products, such as mobile crushing station. The level of mechanization of coal mining enterprises in the southern region is relatively low, but from the overall point of view, the large-scale mechanized mining equipment mining machinery will be more widely used. Enhance the level of technical equipment of mining machinery will promote China s coal mine enterprises to continuously improve the level of modernization, merger and reorganization, as well as continue to strengthen production safety. The crusher equipment re-take the peak will make China s coal resources be more market-oriented, rather than confined in the provinces, which is more conducive to the merger and reorganization of coal enterprises to achieve greater development. as the leader in the mining equipment industry, Hongixng through technological innovation first complete the implementation of energy-saving and emission reduction, provide high performance and low power consumption crusher equipment to promote the production and environmental protection of the coal enterprises. Expert analysis, not only the international financial market vicissitudes, the domestic market is also facing pressure on monetary tightening, the economic situation at home and abroad directamente impact on the import and export of goods.
In accordance with the trend of the traditional market, the construction machinery industry market sales for November and December will decline, but the rate will not be too large, it still continues to push up overall sales for 10 years. Hongxing Mining Equipment Co., Ltd. believe, if we fully applied high technology to our own machinery manufacturing and upgrading, we will catch up with the pace of merger and reorganization of coal enterprises and provide solid backing for mining machinery industry and mine construction transformation.
