An amplifier world, share NEC
- Your business data safe?
Into the 21st century, corporate business and information technology more closely connected, information has become the core competitiveness an important part. For example, according to Qualix Group's statistics, the loss of the securities industry, down 45 per million, communications, banking and other industries each downtime and 27, respectively 350 000 million. An important feature of these industries is very strong degree of information technology, the dependence of the entire information system is also very strong. In a sense, business dependence on information systems stronger, then the information loss caused by system failure is greater. Information important in the enterprise to raise the degree, but also more and more emphasis on the enterprise server in the enterprise application reliability.
On the other hand, the development of information technology, data followed the collapse of the threat of downtime will be growing. According to the National Computer Security Association, 20MB each lost critical data, sales / marketing department will lose 17 thousand U.S. dollars, the financial sector will lose 19,000 U.S. dollars, engineering department will lose 98 thousand U.S. dollars. Even third-party statistics that the loss of business critical data for more than 80% of enterprises are bankrupt eventually. Therefore, in this sense, the enterprise data storage also requires a very safe environment.
For companies in these two needs, NEC Corporation in 2005 September 16 to October 28, in Beijing, Shanghai, Shenzhen and other 11 cities, followed by start the theme of "Generosity security world, share the NEC "large-scale server and storage customers nationwide tour activities, through practical application shows users and partners to introduce NEC servers and storage products, features, and they are the perfect integration solution.
In the event, NEC server specialist will be fully introduced the latest NEC server products and technologies, including the latest upgrade of fault-tolerant servers, and storage experts will thoroughly explain the NEC's storage strategy. Participants will also invite users to the implementation stage of the three simulation experiments to show that NEC products and solutions with high reliability and high availability. NEC servers and storage technologies perfect match, will provide a strong adaptability of Chinese enterprises IT platform to help Chinese enterprises in the fierce market environment for rapid growth.
The first experiment is to verify the fault tolerance fault-tolerant servers. Removal of fault-tolerant server, the user can any of these components to simulate the server computing system failure - we can see, the server monitoring equipment to detect anomalies and administrators as the police, but the practical application of front running are not affected.
Can be said that application security is not a new topic, in order to address the application of downtime may lead to disruption of the losses, the industry already has a very long "hot standby" solution, the program is still in many applications place widely. However, as "hot standby" mode technology to provide system redundancy still exists more than 10 seconds of application switching time, a number of real-time data may be lost, while the system has only achieved 99.5% availability. This means that for has a 365 脳 7 脳 24 job demand enterprises, 43.8 hours per year are forced downtime.
Fault-tolerant servers in the fundamental solution to this problem, the server which are mirror images of the system 1 and System 2 to run the same program. And fully synchronized in order to achieve the continuous operation of the maintenance, and provides an efficient exchange of maintenance mode module. In the fault-tolerant servers to achieve fault-tolerant hardware component availability, the system all the hardware module (CPU module and PCI modules) are designed with redundant and equipped with ASIC circuits for data processing results to the continued synchronous cross-verification; so that the failure of these modules will be automatically detected, the module also fails immediately and the system can be separated.
Domestically, the market hot standby system reliability essential in 99.9%, while the fault-tolerant system has been able to achieve 99.999% reliability. That is, application fault-tolerant servers, the company can be the down time throughout the year from 8 hours a day down to 5 minutes. In troubleshooting, traditional hot standby failover is when the host fails, the Standby machine to restart all applications. In other words, the client will terminate the ongoing operation, carried out by the business needs to start from scratch, this will inevitably lead to the loss of the user's current task. And because all applications need to re-start, switching time over at least 1 minute. In contrast, fault-tolerant system, the more obvious advantages. When a failure, because Cache, memory and hard disk data is fully synchronized, and two systems to work simultaneously, so just need to switch the output from the fault section can be transferred to a normal part of. The current task without end, completely seamless switch in the past, almost no switching time (applications that do not feel them).
The second experiment is the NEC's highly reliable storage device experiments. NEC's storage device to provide a redundant RAID 6 technology that allows the storage array damage any two hard drives simultaneously. In the field simulation, the user can from the system random device among them two hard drives, then the user still maintains the integrity of the data, no data loss.
The development of enterprise information so that enterprises in the explosive growth of data, this also means that as the basis of enterprises in hard disk storage unit number is increasing. When companies increase the number of hard drives, hard drive also means increased risk of damage. Traditional RAID 5 redundancy mode allows only damage a hard drive, in which case the data can rebuild.
However, in the user's data center practice, sometimes there may be damage to the hard disk to happen without warning. Therefore, two hard drives to ensure data security can still damage the RAID 6 technology for providing a square level of reliability. NEC's implementation of RAID 6 technology independently developed by LSI (logic) to hardware implementation, fully able to meet the needs of the user's IOPS. NEC said that if the combination of RAID 6 and NEC's dynamic pool of storage technology, 1 TB of data reconstruction can be completed in 2 hours. In the Tour presentation live, the data reconstruction only takes a few minutes, and can dynamically increase storage capacity. In contrast, many storage devices to add storage capacity, still need to break applications.
Be noted that, NEC's RAID 6 technology is evenly distributed in all the data on your hard disk. Therefore, in this tour, NEC is removed which allows the user to any two hard drives. In the early stage of RAID 6 technology which, for data redundancy check code is mainly distributed in two hard disk, two hard drives which can only be allowed to damage the piece, otherwise the data will be lost. Although this is higher than before the raid 5 in redundancy level must be high, but not ideal for RAID 6.
NEC's S2400 family of storage products also provide the Phoenix (Phoenix) technology, when the hard drive or temporary 澶辫触 response delay when the time is detected, Ta immediately for the shortest temporal isolation and back-Zhen Duan, and Zuochu rapid processing, the temporary failure if yes, the system automatically after the repair bay. Thus without loss of data can be achieved under the premise of 1 / 3 to 1 / 2 to save hard disk replacement. Not only saves money for enterprises, but also reduced the staff time and other maintenance costs.
The third experiment is zero risk of online expansion demo. In the last experiment two simultaneous drive failures, based on the data line into the hard disk to restore the system on-site users at the same time, please create trouble, unplug the power lead to system failures, power supply connected to continue to run after the system restarts, the data is not lost, to complete the whole process of online expansion. NEC said that it is the combination of RAID 6 and dynamic pool of technology, sufficient to prove that the IOPS performance RAID 6 system has been able to meet customer demand on the transmission performance.
NEC is the world's fifth-largest server brand, product line complete, including traditional tower, rack, blade, and fault-tolerant servers, water-cooled servers to industry-leading high-performance, high reliability and manageability for customers with the most excellent standard solutions to provide customers a wider choice and value. NEC servers and storage technologies perfect match, will provide a strong adaptability of Chinese enterprises IT platform to help Chinese enterprises in the fierce market environment, to achieve dynamic growth.
The exhibition is the NEC server and storage market in 2005 the main activities will NEC's server and storage products provide a good opportunity for promotion and sales, but also will better support the channel partners. Can see that with customers, partners, close contacts and exchanges, NEC servers and storage will be broader and more in-depth application.
