RAID will become obsolete

Once upon a time, RAID has great appeal to the user, the user is useful, but that does not mean that it is the user needs, and now users need better technology.

Disk capacity is no longer expensive

RAID can improve disk performance and, more importantly, in the case of disk failure, data protection, and ensure system reliability. However, since the invention of RAID technology, the world has undergone fundamental changes. Some storage systems are now on the RAID technology to minimize the use of, even some systems have completely abandoned the RAID.

When the initial development in the RAID, disk capacity is very expensive, is to be considered first, management simplicity and scalability of the importance of the fall in the second. Today, the management of hundreds of TB, or PB of data is a very commonplace thing, therefore, managing complex storage environments based on RAID technology is becoming difficult to accept. Now, the disk capacity is cheap, difficult to manage as a more important question, for RAID, we should change our understanding and practice. Long as they can significantly simplify storage management, in order to protect the data, we can expand more storage capacity.

RAID is quite complex

Why no RAID technology? It is too complex and require too much manual configuration, adjustment, analysis, and site management. It also sacrificing performance. If the reason was not sufficient, RAID reconstruction will always spend hours or even days. Since the emergence of self-RAID technology, RAID level RAID 0,1,3,5,10,30,50, and currently has JOBD etc., in addition to RAID 6,7,5 E, 5EE, DP, ADG, and many other proprietary standard RAID levels . Different RAID level, the combination of different hard drives, disk arrays to provide users with the performance and safety performance are also different. Range of levels of standards have been dazzling, management costs can be imagined.

What technology will replace the RAID technology? Who cares! In order to protect data from loss, storage systems should provide the availability and continuity of the normal working hours, the user should not be forced to care about RAID levels, or any other technology will replace it. In other words, users really need is to completely put into logical storage pools and virtual stripe of data storage systems. Then, when the number of drive failure, the original data should be able to back up the logical pool integrity preserved. All these operations should be transparent, and never need RAID reconstruction. When a new disk drive to the logic of the pool, the online and transparent process as the original data and backup data should be able to automatic load balancing to a new space. This is a simple and clear way. Perhaps this approach sounds a lot like RAID technology, but on the contrary, the current RAID is quite complex and confusing.

Goal is to reduce management stress

For all these reasons, from the consumer to high-end market, RAID must die. A "Fortune" 50 head of enterprise systems has said he needs is an enterprise-level performance, but managed like a consumer-level storage systems. If this is the user's goal, companies need to change the inherent understanding. Elimination of RAID technology is crazy to think of it, but if not, storage systems will never reach the necessary level of ease of use.

The rise in recent years a number of techniques to enable the industry to see some hope. Have businesses clustered storage modular architecture, each node including the intelligent control and the disk in two parts. When a user writes a file a certain cluster storage system, a node, this node will automatically split the file into several parts, reasonable storage to the system all the nodes. Clustered storage systems integrate all the devices to a virtual storage pool, the formation of a transparent global file system, not only improves the existing disk resource utilization, in turn relieves the pressure on storage management.

Beginning in 2007, solid-state hard disk access speed for its small size, easy to carry, and low energy consumption gradually been welcomed by many manufacturers and users, EMC has just announced their high-speed cache to DRAM as the center of the DMX Series storage system installed on flash-based solid state disk. Traditional disk and RAID technology dependent on it, are subject to a solid state hard drive challenges.

Some of the next generation of enterprise storage systems are simplified or removed RAID, this exciting, big companies should be the same the cards. The reason is simple: large companies have to promote market forces, to give way to promote RAID technology. High-availability storage systems no longer need RAID, the need for new technology to meet today's challenges.

Parameter
Preserve

When changing an existing one-dimensional array of the size of the final to retain the data.

varname

Variable name, follow the standard variable naming conventions.

subscripts

Dimension of the array variable, up to 60-dimensional array declaration. subscripts parameter syntax is as follows:

upper [,upper] . . .


The lower bound of the array is always zero.

Common JSP Title 8: JSP's basic concepts

Element Union and day encounter in the rubber of the Kingdom of thinking

I believe we are no strangers to the rubber, our lives and work are inseparable from the rubber products, such as the common automobile tires, remote control button and the phone keypad, computer keyboard keys and so on. From natural to synthetic, our living and working space is full of rubber products, we seem to live in the rubber of the kingdom. Have such a variety of rubber products, rubber will have numerous manufacturers, Rubber Products Co., Ltd. Shenzhen Yuan Union is one of them, it has been since 1992 the Kingdom of travel in the rubber 14 years. Recently, because of some inevitable reasons, so that element Union and Zhuhai days thinking software group met together here.

Element Union Rubber Products Co., Ltd. is located in Longgang District, with convenient traffic, is an earlier development, production and conductive rubber button one of professional manufacturers, the existing plant area of 8000 square meters, flat vulcanizing machine and ancillary equipment 50, through the years development, now has become a product design, mold manufacturing and product development of one-stop services to medium-sized professional producers. Currently has a mobile phone key, P + R, remote control buttons, silicone rubber parts and other products. Element Union has passed the IS9001: 2000 international quality management system certification, and "customer first, sincere service; quality-oriented and progressive" as the guideline, establish a perfect quality assurance system. Technology innovation is the element carrying the dismay League goal, this element alliance with the Hainan Rubber Research Institute have jointly established a technology R & D team.

Element Union is steadily growing rubber in the kingdom, but with age, element Union all have varying degrees of development, growing up to do business, more and more orders, and orders increased, and changes frequent, so that more and more products, more and more complex types of materials, giving the management element Union posed a great difficulty, requires a lot of manpower and time management can all work a little order smooth point, which sometimes affects the progress of production and company profits. Anyway, per league will not be such a thing at this time stumped for. "宸ユ鍠勫叾浜嬪繀鍏堝埄鍏跺櫒" element Union decided to use modern information management tools to improve the company's management.

Rubber in the vast kingdom in alliance for rubber element is so familiar, but now is not looking for rubber products, but a management tool, which before had any contact for information management tools for the meta-League a bit confused, just like to find a huge crowd, only know that facial features, but there is no other more detailed information on the people, it is very difficult. Emperor it pays off in dollars alliance management tools and trouble to find the time, day thinking alliance partners to find the dollars for yuan AU detailed description of the day thinking managers ERP in manufacturing, and professional advantages, so that element Union understand the many days of thinking ERP company in the successful implementation of the case. Element Union will also be days thinking manager ERP and other software manufacturers at home and abroad to conduct detailed comparison of management tools and found that day thinking more complete ERP functional and has great stability and flexibility, can adapt the production per AU model, but also to see the sky thinking element Union partners services can play a day thinking more perfect ERP manager. Based on this detailed comparison and analysis, per league managers selected days thinking ERP, per league encounter with the days of thinking this way together.

Recently, the days of thinking the implementation of ERP staff have formally launched a related work, Yuan AU and days thinking the Kingdom of the encounter in the rubber element will lead the development of higher level league.

Fully compatible with and support the collection of Thunder Win7 new trial

With more than 5.8 Thunder 5.9 upgrade, but we regret that there are some 5.8 features are still not a smooth transition to the 5.9 up. Meanwhile, the popular trend in Windows 7, today intensified, Thunder must be achieved "with Windows 7-compatible", and then developed with the corresponding features. In addition, for many browsers, it should also provide a better Thunder "native support." Fortunately, with the release of new version of Thunder 5.9, these features have already been resolved. A fully compatible with Windows 7

Security light, performance, digital home, multi-touch, unified hardware, network and opening up, virtual operation, the file library and other features, enough to make Windows 7 captured the hearts of many users. As a good download tool, Thunder must be provided with compatible features. The release of the new Thunder did not let us down.

In the first install and run the Thunder, it will pop up the window shown in Figure 1, requires us to set the default download folder, and prompt us to "build the library in Windows 7 Thunder download." After the opening shown in Figure 2 as long as the "library", you can see the "Thunder download" folder. So that we can use the Windows 7 in the library functions to manage, search for Thunder download the relevant information.

Tips

If the first does not create a database in Windows 7 Thunder download, you can also select "Tools" 鈫?"Configuration", click on the left of the "task default properties" tab, you can see on the right "to establish the library in Windows 7 Thunder download "check box, select the can.

In addition, the new version of Thunder 5.9 also fully supports Windows 7 Toolbar JumpList function (Figure 2), as long as the Thunder right-click the toolbar window can, in addition to access to the most recent three new tasks, you can also use the Thunder most common features, easier to use.

Second, the new collection features

Although search engine is easy, but very often, we hope that our resources can be downloaded at any time for us to use. Thunder to provide similar services, you can download the resources for the preservation of our online, to use at any time to download.

Thunder 5.9 also adds new "Favorites" feature, we can right-click the downloaded resources, select "Add" command or simply click "Add" button (Figure 4), you can save their favorite content to the network , ready to download and share with others.

Third, to strengthen and "offline Download" Integration

Offline download, also known as offline download, is a network of alternative high-definition era. I believe we have to understand offline download, it can solve the energy waste, electromagnetic pollution and other issues, easy high-speed download. Thunder is a new version 5.9 has been enhanced with the "off-line to download" The integration (Figure 5), this operation can be better off to download.

Quick question

4, New Boss Key

Recently, the "boss key" word has become popular. Boss Key is used against the boss (or boss, parent, girlfriend or other person) as long as the press of a button, can make their own ongoing do not want to be seen any of the content disappeared in an instant without film without leaving a trace, protecting your privacy. Now the software is also very intelligent, have provided the boss key feature. Thunder 5, also provides similar functionality, so you can at any time for our "quick Disembarrassing."

Select "Tools" 鈫?"Configuration", click on the left of the "Common Settings" tab, you can see on the right "to enable the boss key" check box, then press the appropriate button to set the boss button (if not recommended with the default Alt + D).

Note that the boss key is to open the key, press a hidden, press again will resume. So do not use the default Alt + D key, which is more easily discovered by the boss.

5, support for more browsers

I am sure the Microsoft monopoly case must be heard, but also let us know more browsers. Thunder the previous version 5.9 is not able to "native support" outside the browser in addition to IE, is very much a regret. Thunder is a new version 5.9 solved the problem, in addition to support for IE, but also support Maxthon, Firefox and Opera browsers. We can choose the "Tools" 鈫?"browser support" command from the row selection (Figure 7), so you can let us do not change the browser and change the browsing habits of the premise, enjoy high-speed download Thunder 5.9.

Overall, the new Thunder 5.9 has achieved Windows 7's fully compatible with, and provide Windows 7 features, while also increasing the collection of new features, support for the boss key, and also to support more browsers, worth downloading update and try. I believe the download will become a weapon!

Auto Attendant computer operator

1. Introduction:

High efficiency, fast-paced today, telephone is an important tool for information transmission, the level of its services. Quality directly affects a Hotel up, commercial buildings, the company's reputation and image. The traditional attendant console manual calls received by the switch can not meet the needs of social development. The face of growing traffic, how to faster, more accurate to take turn every call; the face of a large number of phone messages, check request, how to accurately record, notification and rapid response; the face of the attendant console has less load manual call forwarding and backward way, how to improve and update! To keep up with the pace of information delivery has become an urgent task manager! In response to these circumstances, Guangzhou Tsui Sing Yuen Technology Co., Ltd. developed intelligent voice system, the computer operator with the unique combination of voice mail, then switch to manual and computer integration in two ways, the work of the current switchboard injected new vitality the same time improve the telephone service grade!
