Nobody knows its real meaning to just a is propagandized again every several years. Storing the circle, store Virtual And information life cycle manage information lifecycle management – ILM It is two real examples, they receive the supplier’s maximal concern, claim to reduce cost and complexity of storing the basic framework, but never really accomplished. Store by the cloud in the latest and greatest technology of frying line top of composing music.

These round propagation that the cloud stores and float in the excuse this pun Long-range objective bring to data storage supplier any advantage, but it seems not to take ILM and and store the virtual old road. Not as ILM and primary 2001- Among 2002 It is virtual to store, using the cloud can bring the genuine advantage immediately while storing level:

All right inscription operation cost, on the basis of the service that is subscribed.

Reduce disposable and future and capacity.

Close to perfect economy, the user pays only for the capacity that uses

Reduce the operation cost, because the can manage the basic framework more high-efficiently, because of their all right multi-user shared resource, and it is outward and expanded and virtual to use and store the platform.

The business flexibility improved, include meeting the provisional capacity demand briefly.

There are these advantages, why do not users have arms which join in the cloud? In fact, still some various doubts about inner of cloud, and store some formed to the cloud puzzledly. IT manager leaves to enterprise’s information anything a bit bigoted will take place in the sphere of influence of enterprises IT, it is a good personality for IT manager. However, if you keep an eye on carefully, will find the cloud stores and already used in some organizations the data to file layer, and it has offered the advantage of saving the expenses for a long time.

File level in valid data

The cloud stores the access mode, very suitable to delaying the insensible data needing to keep to those for a long time, share among a plurality of users, need to be simple, this digitized medical treatment and the demands of medical records exactly influences. These require it, and then consider explosive half a structured data that increases of medical trade from case history and can produce meticulous content of picture, collect progress of apparatus, drive of electronization ,It is very clear that the cloud stores the reason to file level as the medical trade applicable data.

In a lot of cases, the regional medical system shares the central digital image to file to store the picture from similar CT scanning and X-ray machine. Filing that share these can think it is private cloud that store, filing of here serve, offer into medical the intersection of network and member, regarded as a low-cost way to pass IP network stored image and medical records. Dispose the cloud and store and file the worry that can avoid the safety in a private memory cloud, because the store service has not shared with the medical network.

Not the machine format high growth of the structuring is not only the problem that the medical treatment industry faces. ESG estimates the data that are not the structuring will take the overwhelming majority in the commercial data of data centre in 2012, this will influence big and small companies of all trades and professions. With the intersection of Web2.0 and applied appearance, until how store data and how long ‘s increase of regulation does it store, and the increase that the multimedia used, the merchandising concern will see there is a speed that has increased in the past in unstructured data. Most unstructured datas are only often visited during two weeks establishing at first; Visit capacity drops even stops gradually subsequently, but because of business or reason supervised, it still needs keeping for a long time. Data these it has to be may short-term data greatly, can transfer to COMMON filing layer based on cloud in being from expensive 1 layer or 2 layer to establish it.

Technology has already possessed, but you should be careful. The feeler of Internet spreads all over each corner of the world, in fact has set up one tabular world network, it is only very few if really having Connectivity barrier. Wide area network WAN The network link that is accelerated and seen everywhere makes the business run in any place. In the forward position of the platform, expand outwards, offer the platform based on commercial system of augmentability of magnanimity, data transmission and scale economics keep the ease of use and very managerial at the same time run side by side Have already existed. And can tolerate the long-range stored data the delayed procedure attribute caused is understood better by everybody. The cloud stores the persistent data that can work as the layered model of now to keep. And finally, the association of dealers of supply spends the stage when is propagandized to transfer to discuss and can be offered now something.

Use the technical pluses and minuses of virtual storage in the fictitious tabletop

May 20, 2011 by · Leave a Comment
Filed under: Chip Road 

The fictitious tabletop arrangement cost high, whether meanwhile will you please offer the sufficient characteristic become even to challenge. Store the framework with the because of these and is closely related with, the problem solving through using the virtual memory technique to come of some controllers.

Now, we will tell that apply the technical pluses and minuses of virtual storage in fictitious desk-top environment. However, before at the beginning, should pay attention to some at first: Virtual storage is not that only one kind of product or technology can be realized. A lot of memory suppliers offer their own difference schemes. In this text, I am to storing the virtual definition: Lie in fictitious tabletop or hypervisor And between physics store, offer a of the abstraction layer.

Store the virtual advantage used for VDI

In fact the result that can reach should depend on different technology used. Most common some includes: Reduce the , raise the characteristic and simplifies and manage. Certainly, these advantages are on the basis of the realization of each products, routes to reach are different too.

It is to repeat the data and delete technology to reduce one of the methods that the stores the demand. Heavy technology is very suitable for VDI system to go, because even there may be a plurality of VHD minidisk inside a company ,But the fictitious disk file that each uses is identical on the whole.

Have, go in weight product while being many kinds of at the market, though they can realize the is saved, but the majority is not used for improving memory performance.

A company named Atlantis Computing Inc. receives a lot of demands for its Atlantis product.

ILIO based on software implementation to go in weight product, directed primarily to the fictitious desk-top environment. Layer of this software locates between hypervisor and storing layer, repeat the data and delete movements in the real time and place before the load IO is sent to the magnetic disc.

It is Virsto VDI that another one VDI environment stores the products that the demand is designed. Similar to AtlantisILIO, Virsto VDI can improve the memory performance of the virtual environment too, but methods to realize are totally different.

Virsto VDI has used the special VHD form, but not VHD framework of hypervisor acquiescence. The final result is a expanded minidisk characteristic of the trends, according to the difference of the company, a certain degree of the meeting is superior to the solid condition VHD magnetic disc. The promotion of this characteristic is realized by that the trade type store the mechanism.

Because there is very strong random property in write operation in VDI environment, Virsto VDI realizes the unified management of the load I/O through the mode of using the trade type daily record, then the phased load is stored to physics. The final result is that I/O operation goes on in a manner to flow, thus realize memory performance is optimized.

Store the virtual shortcoming

Though can realize a lot of advantages through storing virtually, bring some shortcomings at the same time. First of all, though most suppliers declare their products can reduce the , but it needs to be original to be put into to store the virtual products, including the cost of long-term maintenance support. The cost may offset the income losing the and saving to bring finally.

Another potential shortcoming is, stored virtual technology, added one layer in storing the framework after using, have increased the complexity. This makes failure diagnosis after going wrong more difficult. In addition, perhaps you will also find the producer of hypervisor unwilling in order to store environmental the virtual one and carry on technical support. For example, Virsto VDI has used totally different VHD file formats. Though has not met the situation that a certain hypervisor supplier refuses to offer technical support to Virsto VDI customer truly at present, but such a potential risk certainly exists.

Finally, it may cause physical resources to go beyond and use to store virtually. Simplify and dispose the minidisk that technology establishes automatically, the original space is pygmy, can expand dynamically as the space demand increase. Crossing mixing technology of memory resource, so as to need to increase and store while increasing the fictitious secret degree, but if the fictitious hard disk file increases very quick, may result in storing the demand and going beyond the actual physical of .

So, if you are considering as VDI environment and increasing virtual memory technique, the very important point is to weigh the gain and loss among them. Though the result is that incomes are far greater than potential losses under most situations, the factor of contemplating two respects is always right.

We face: Severe situation, and cut down the pressure of the cost. I run into the customers, will all hear such sighing with deep feeling each time.

But the problem solving method is not to just choose the cheapest data . No matter you enterprise, little company or personal domestic consumer, if you care data of you –And if you have read this article, your certain to care about your data –Then you need to consider technology and reliability in are weighed and chosen. The is not merely the price cost of the hardware or software, it also includes operation and –And lose the spoiled cost of data in data.

When I begin to help the customer to understand technology weighs, the first thing that I do is to understand their requirement. Sometimes, the other side meets and looks at me blankly, then tell me that onlies want problem solving, sometimes, the other side will tell me his requirement is to obtain the cheapest memory. Can really understand there are few people of one’s own demand, and can really know less how to employ people of them.

SATA, SAS and tape

Let’s see an example chosen in different typological and tape drive. You may say these drivers can pass RAID independent redundant array Come to protect, but you also need to consider some important things. I think even if the person that calculates most does not hope either you let the data of the company in dangerous state.

The question of maximum is a technical hard error ratio. Any or tape drive all have a hard error ratio, this hard error ratio shows with average bits number. It may be a load too that the hard error is probably read, if this kind of mistake happens, return first false signal claim apparatus to be unable to visit. There are many kinds of reasons such as media mistake, the mistake of the magnetic head in hard Improper emergence, or media trouble. No matter what the reason is, you should consider it is that such Improper probability happen in an apparatus.

If you have one RAID-5 LUN logical unit number Take place hard error is then the the intersection of LUN and necessary rebuild, but if you happen once again hard error in rebuild, then the data will be lost. If you have RAID-6, then another hard error will not be fatal, because you have two check-up apparatuses.

The following is the hard error ratio data of and tape which driver manufacturers provide.

Filed under: Chip Road 

The innovator that stored as the automatic zoning, Compellent in the industry and only offers the advanced intelligence of integration to stratify the function and advanced in SAN Virtual Manufacturer of the function. Not long ago, Dell claimed to finish the purchase of Compellent formally, this indicates too Dell has joining of a new member of those who actually have strength and hold power to store the family.

This purchase is Dell’s newest strategic investment, in order to expand its enterprise layer that repeatly obtains the special honours to store the solution association, have already included EqualLogic and PowerVault before this association. Bind Compellent technology with Dell’s present memory solution, has expanded Dell’s enterprise layer service strategy prominently, contribute to the growth of administrative data, reducing better of the customer, and simplified the management of the basic framework of information system greatly.

The management of intelligence is ready to appear


Division’s solution and service general manager Li Hui of Dell large- in district

Dell the intersection of and the intersection of district and the intersection of large- and the intersection of Division and solution and Li Hui, general manager of service, introduce, enterprise’s constantly changeable business state makes the complicated, less effective have no place nowadays. Saturation of , utilization factor are lower, the data are confused,etc. a series of thorny problem is emerging constantly, the of intelligence is ready to appear. Intellectual has been the memory idea that Dell has advocated all the time, but after Compellent join Dell formally, this idea has been poured into ” The data of flowing ” Fluid Data Fresh blood.

Compellent most captivating , are called by it ” The data of flowing ” Data stratify technology. Have data lasted static behavior much memory products, and find Compellent data are simple ” Store ” ,And the management of intelligence but need to take the initiative, so just there is Compellent ” The data of flowing ” Birth of the idea. The floating data technology of Compellent, has combined a set of strong data migration engine, intellectual software and modularized hardware, can lower costs 80% highest.

Li Hui shows: It is agreed with very much that Compellent original automation, machine format flow, IDM of the virtual idea and Dell are strategic, the joining of Compellent will enrich Dell’s intellectual IDM greatly The idea, further consolidate it and is regarded as ” High-efficient enterprises Efficient Enterprise ” The strategy core makes up the partial status, help Dell to further realize from the cloud, data centre and store the ability that the environment extends to the end point.

Let” The data of flowing ” Intelligence

In the era of exploding of the data, has already become an important link of enterprise’s key competitiveness, and it is great that Compellent is that Dell hands over to intellectual , promote and store efficiency ” The edge toll ” .

The executive director Brian Bell introduces that Dell Compellent the whole world sells: Until traditional in data generation, manage and file way managed to go on different each stage, the intellectual supervisor mode of Compellent embodies in with the whole procedure for eye spot ” The data of flowing ” At the time of the traction efficiency that the framework is here, lower costs and strengthen the flexibility and elasticity.

The key technology of the framework of the data is that the automation is stored hierarchically if Compellent flows. It is introduced, the automatic zoning technology of Compellent carried on management in the block level of the data, and classify and migrate to the optimum storing layer dynamically according to visiting the frequency count. It can stratify between SSD and so different storage mediums of hard disk, can stratify among hard disk of different rotational speed too, can also move the data between different RAID ways. Can let users lower costs and improve the characteristic greatly through the technical solution of Compellent automatic zoning.

Brian Bell shows, Dell Compellent has accomplished the particle size very careful degree, it is the level that the rival has not reached yet at present, in addition users can also follow users’ particle size of automatic definition of actual application. Dell Compellent continues being based on Compellent technology in the future, the ones that especially succeeds in at present simplify the development on disposition, automatic zoning, Storage Center, the next step of Compellent can plan, estimate the intersection of improvement and the intersection of automatic zoning and technical particle size further, offer smaller particle size to raise efficiency and characteristic of the products.

How does the network storage system realize the intelligent system management

March 1, 2011 by · Leave a Comment
Filed under: Chip Road 

The tradition stores the network framework ‘ Such as storage area network and Deficiency,last supplier productses with them, in order to let their products become more intelligent. Nowadays, IT manager is seeking to contribute to realizing many suppliers’ interoperability, protection data, shared information and solution of simplifying management constantly.

However, because such new thought will introduce the similar function in the whole apparatus which store the network is made up, so increase the complexity of management, make those enterprises that has already invested a huge sum of money in storing the network equipment hang back at the same time.

Store the trend of the framework: Develop towards NAS and SAN from DAS

For many years, traditional DAS directly connect is stored The model has been deciding enterprise’s computing environment all the time, but already in the backout mainstream at present. In recent years, Internet application and intensive application of other data have caused and increased the unable predicted fact of the demand in storing, this has not only fully exposed the deficiency of DAS model but also influenced protection, sharing and to information. In DAS framework, the server will be ” monopolized ” . Including the information that different servers are being stored in the set is being difficult to sharing, and once the server exhausts one’s own , it will be unable to utilize any other .

IT controller must manage the distributed one by one, extraordinary holding time of such a task. Need going on the backup of each server separately too. When needing high capacity, will be meaning needing to buy more storage equipments. If the company has a dozen servers or more than one hundred servers, the may become maximum expenditure in IT budget.

NAS and SAN store the appearance of the network framework, the hope of this kind of current situation that bring energetical improvement. NAS does not distribute the to each server, but offer the storage function of the file for LAN directly, in order to be used as network application and user. SAN is a kind of specialized memory network independent of LAN, it, through using optical fiber channel or Internet agreement switchboard to offer the storage function of the batch for server and work station. Unfortunately, NAS and SAN have used different typological storage equipments and network, thus has caused the awkward choice in the .

Store the advantage of the network

From DAS to store the transition of the network, great amplitude enhancement information management level. The main commercial value that can realize after summarizing and adopting and storing the network as follows:

Reduce idle hour

After using the network to separate the with the server, can change the disposition on condition that influence other business. Storing the network reduces normal and abnormal idle hour.

It has no restriction to expand the characteristic that on-line

Store network, get rid of physical constraint of augmentability, and server independent at present. Increase information capacity or handling capacity, will only need to add the new or application server. In addition, only need to add the switchboard and expand the scale of the network at will.

Simplify and manage

Reach and store integration of DAS information in the network, can reduce the required memory management task greatly, and reduce and store the handling cost directly.

Support the server to troop

Compared with server of the single, critical application uses the server to troop and can realize more high reliability and characteristic. Can visit the information stored continuously with the share mode while trooping the technical requirement server, so it will be indispensable to store the network.
