How does the data centre manage real-time intellectual routing
Generally speaking, as to the comprehensive wiring system of the intelligent building, we think ” the intelligent management system work of comprehensive wiring is on the physical layer “, and the intersection of network management and software work in network layer usually, it can tell network management person trouble of logical link, but the position of the physical fault of the persons who can’t tell the network management, this is one of the functions of the intellectual routing system exactly, the intersection of offering and routing system whose intellectual routing system is can real-time accurate convenient carry Link connection to reach end, and real-time monitor its state, and automatic updating, all information files of record are reached in the database, operate complexity sparingly, improve and manage efficiency. ”
More data centres:
Remarkable cabinet management application
Diversified data centres
To the understanding substantially as having, perhaps readers will have doubt, perhaps these functions might not be useful in the data centre, if really like this, why does the data centre adopt the intellectual routing supervising system then? Answer this question, should be to understanding that does a analysis as above, should say this understands it is not overall first, because of the real-time intellectual routing supervising system, its main idea is: “Visual Knowledge Control ” . How to understand this idea? ” visual ” Namely combine the routing system and set up the visual basic framework supervising system through the software and hardware, ” knowledge ” It is namely can ocular see whether can if you can’t help by administrative staff, set up by global concepts of framework basic, ” control ” Because of have intact basic concept of framework, pass operation of procedure then, avoid the artificial fault, thus improve and manage efficiency greatly and offer the high-quality service to forward end user, meet the target of reducing and managing the running cost finally.
In sum, one that is to data centre intelligent to manage, there are many kinds of relevant software systems at the market at present, but generally all regarding many manufacturer apparatus platforms of the data centre, including the server, network equipment,etc., so as to transport and link the administrative staff and carry on audit, ensure security,etc.. And ” real-time intelligent supervising system ” The master difference is: It is the setting-up in the platform of software and hardware of intelligent distribution frame of group at first, the system secondly through the software and hardware one has offered the visual management tool of infrastructure of a set of real time physical layers alternately, set up one the intersection of physical layer and basic the intersection of facility management and procedure on the basis of the above-mentioned bipunctate finally ‘ The electron working single system On Yu Qi. This is basic difference of a real-time intelligent supervising system.
Such as the table below, select from ” routing system design and white paper of construction technique of data centre “, this form has summarized pure software and difference functionally of management of the software and hardware platform.
Routing management Pure Software intelligence electronic routing supervising system
Hardware
It set up system data last craft craft input Systematic automatic recognition
Conductor arrangement connects and changes the record to record real-time automatic recognition by hand afterwards
There is not failure recognition yes
The data are not automatic after systematic fault recovery

The procedure of the job note turns into and record producing by hand and record by hand
The graphic interface is that yes
There are the related floor flat graphs
Must compare, it is likewise the procedure of job note through this table, though set up by hand through the software, but because intelligent supervising system have the intersection of hardware and cooperation of platform, make electronic execution operation of job note, can be navigated by the operation of the intelligent hardware platform, and there are the records of intact plan and non- project operation, this makes integration based on that the tube of the electronic job note can be very good get in the management of procedure, this can’t be realized by pure software system.
The whole attack strategy that the apparatus of density of hyperpyrexia of data centre dispels the heat
For many years, because of increasing the density of the server and magnitude of reducing its volume, density of server become more and more high, with in addition Virtual , cloud calculate employ technical wide application, data centre produce more heat day by day. So, the wattage which produce heat of each square foot is rising constantly, the increase of this kind of power density is threatening the stable operation of the data centre seriously. Show according to relevant research reports: The density exceeds 5kW / cabinet to generate heat, adopt and refrigerate the form of blowing under the most high air conditioner floor of computer lab of efficiency, also will produce some focus on the crest of the cabinet, it is apt to lead to the fact the apparatus is overheat protective.
With popularization of the full-fledged computer, the utilization rate of equipment of the data centre is raised, a large amount of application of the blade server, the density that and generate heat to high power density, cabinet inner power supply, heat-dissipating problem become the key of development of data centre. Problem of refrigerating that the apparatus of density of hyperpyrexia of data centre dispels the heat in order to solve, roughly there are areas of density of hyperpyrexia that solve the way, some focus and solve ways such as the way, cabinet of density of specialized hyperpyrexia,etc. at present.
Regional solution of the density of hyperpyrexia
The area of density of hyperpyrexia solves the way, concentrate on decorating the apparatus of density of hyperpyrexia in the computer lab, form the area of density of hyperpyrexia, adopt the way of refrigerating of the corresponding density of hyperpyrexia in this area. For example: Close the relevant cabinet, isolate the cold, thermal current, prevent cold thermal current from mixing and reducing the efficiency of refrigerating. The conventional method is, close the cold wind passway space of the cabinet.
This method can guarantee in the computer lab, the cold, thermal current is totally isolated, but cold, thermal current is not being mixed, the cold wind that the air conditioner of the computer lab is sent is all used in the apparatus and refrigerate, has extended the static pressure case to the space of front of the cabinet, have fully utilized refrigerating output of the air conditioner of the computer lab, has raised cooling efficiency, has solved the heat-dissipating problem of density of hyperpyrexia of the apparatus. This way needs to concentrate on fixing up the apparatus of density of hyperpyrexia, concentrate unitary refrigeration, power supply,etc. on managing. So, require that does a good job of planning, separates apparatus of density of hyperpyrexia from ordinary heat-generating equipment on data centre design phase, concentrate on fixing up, managing. Industry have the close method of space behind of cabinet too, in order to operate and maintain against the apparatus in the cabinet.
The close area of density of hyperpyrexia of passway space of cold wind solves the way, easy, but the inner apparatus of the cabinet of density of a hyperpyrexia dispels the heat and works, can realize than more high refrigeration efficiency of the way of blowing of air conditioner of general computer lab at the same time normally. Limited to computer lab air conditioner blow refrigerating output, way’s and settlement’s the intersection of heat and as some other kinds of the intersection of enhancement and refrigerating the intersection of hyperpyrexia and the intersection of density and way of refrigerating density this. It has it through closing the cabinet that in the industry, close the cold wind the method of the space of front in the cabinet, this method can compress the space of the cold air channel, but refrigerating capacity is lower in the cabinet.
Time the intersection of edge and network from the intersection of 100 Mbps and staging to giga Ethernet?
Hope for the garden LAN LAN correctly Edge last the ones newer network engineer face not choosing basically each: Fast Ethernet or staging that still uses 100 Mbps get to giga Ethernet GbE . Undoubted, supply with the association of dealers to recommend engineers staging to more expensive GbE, but the network engineer must decide which kind of basic frameworks business to you is appropriate by oneself.
More Ethernet:
Safe happy communication moves and passes back and increases intelligence, Ethernet and capacity for intelligence
10Gb Ethernet optimizes and can’t only depend on the hardware
10Gb Ethernet – -Future of the data centre
Though enterprises are changing the server, tabletop and notebook computer constantly, but often there is one to expand course on edge of the garden LAN. Edge of your next LAN is upgraded and can still be used from 5 to 7, so you must consider carefully between fast Ethernet and GbE.
The teacher Michael McNamara of technological consultation located in Main Line Health of Philadelphia shows, “though has cancelled the new data centre or construction of new fictitious basic framework, but is still wearing out in the basic framework of the marginal network constantly, in some cases can not already far employ the requirement. ”
McNamara says, in 2007, LAN edge of Main Line Health begins to change from Ethernet fast into GbE. The company installs one giga of switchboards in all new construction or transfermation project of the garden LAN. McNamara estimates, it is GbE that he has 35,000 35% of the edge ports which carry the oral network altogether.
The price is not the only obstacle of staging of giga Ethernet
Though GbE is comparatively ripe, it is still much higher than 100 Mbps in price. According to data of IDC, one GbE it carries the oral price to be might be 4 times higher than one fast Ethernet. Fast Ethernet and GbE may whether great majority consider staging the intersection of network and engineer of network consider a factor most in wide gap in price between the switchboard. However, the question is far from so simple.
It is not merely a switchboard changed to migrate from 100Mbps to GbE in the Distribution cabinet. VoIP telephone model of much medium-sized scale has offered one and 10/100 of the Ethernet to transmit, it allows the telephone to share a network link with desk-top PC. Migrate this tabletop to that VoIP telephone that needs one Gb too of GbE, or need to connect user’s tabletop with another network, these two kinds of methods will both increase the expenses of project. GbE staging take to all earlier stages standard Power over Ethernet PoE too And CAT3 routing leaving over is paid and changed.
McNamara says, ” we are dealing with a nearest one to purchase, meanwhile, we find that there is much physical wiring device that adopted the swift connection, this is a problem to be solved at present. I still see a lot of people ignore and despise the wiring device of them, but they often need to inject capital into in this respect finally. ”
Finally, the network engineer must put a basic problem in order first before the staging gets to giga Ethernet: Do you need so large bandwidth? Under many circumstances, the final user’s utility program will not be consumed fast with all bandwidth too on net, it seems like this that GbE extra capacity seems to be a pointless investment. Devoted to the collinear network engineer of group of the network performancing will possibly explain 100 trillion networks have already offered the sufficient capacity for their edge network.
However, the network administrator must compare the present bandwidth demand for their LAN with project network demand of the following 5 years. Most enterprise migrate VoIP and telephone service to already with too online, thus lead to the fact the bandwidth demand is increased sharply. With the desk-top video conference and arrangement in a lot of enterprises of the whole camera of IP video, the video will be that the next kind cause media form in which bandwidth demand increases. More widely use wireless devices to increase the flowrate of the wireless LAN basic framework too, including notebook computer, intellectual mobile phone and dull and stereotyped computer, it influence collinear backward stroke network that this will be reversed. The network capacity is planned must consider all these integration gets by different systems too on net and whole growth of the organization.
Banking industry utilizes the cloud to calculate to meet the convalescent demand of the disaster
A lot of banks are beginning to use the cloud to calculate to serve to meet a very key, very responsive respect in their technical requirements: The disaster resumes.
Rely on cloud assumed bank can in rent the space at the server of management by third party, but not the hardware of the management server inside the organization. It is expected to save the fund, shorten recover time for the bank that the cloud calculates to serve, but up till now, has not been adopted even after stalling for a long time, the smaller bank is serving as the pioneer.
John O’Brien is health Gary state bank Congaree State Bank of Colombia of South Carolina Executive vice president in charge of information technology, he says: “Our IT cost related to resuming in disaster is expected to cut down half, recover time is expected to be shortened to 1/3 too. ” He says, ” will have several hours only, but not present several days recover time. ”
Gary state bank of the health is divided into two branches, has assets of 122 million dollars. It began with the security system company Safe Systems Inc. of the market of Al and Falley tower in the state of Georgia in 2006 Cooperation, use the trusteeship E-mail service that the latter offers. This bank plans before midyear of this year the trusteeship disaster which implements the security system company resumes the service: Continuum.
Subsequently, Gary state bank of the health will resume planning the disaster to use the redundant server of a place among this bank originally, turn into a server of strange land which uses the security system company.
O’Brien says: “This can utilize resources effectively, can also help us to meet and supervise demanding, fulfilling the shareholder’s obligation, namely one resumes the plan, in order to let system recovery run as soon as possible. ” Face the intersection of disaster and convalescent cloud, serve not only all right stored data, still can make mirror images to the whole network. The mirror image system usually includes software application, disposition, mechanism and its his respect facing storing and middleware.
In case meet the disaster, ” you need to construct the whole computing environment again, ” The chief executive officer Bernard Golden of HyperStratus Company says, this is that a cloud located in holy Carlos in California calculates the advisory company.
Then, the bank can use the data link connected to the cloud service provider, from remote to continue, run own system. Once the bank builds up physical site again, the provider can send the mirror image system of the bank to the site built up again subsequently.
Long-range some top manufacturers which resume the trade include Computer Associates International Inc. Company, International Business Machines Corporation IBM And SunGard data system company, in addition there are some less providers such as i365 Company, BlueLock Company and Doyenz Company of Seagate scientific
