Compact midrange disk arrays, space S2500

In recent years, the end user's storage needs grow faster, both for capacity or performance, their request is not inferior to high-end users. Growth from the market situation, the growth rate of mid-market significantly larger than the high-end market. The end user needs in the end is what? Through in-depth analysis of user needs in China, NEC found the answer: high-performance, economical, but also high value-added.



Rack-mount disk array controller unit configuration


More optimal performance

With the rapid growth in data volume, and frequent visits, SAN network for data transmission bottlenecks are becoming evident. NEC fiber midrange disk array family, a new member - S2500 the first to break the deadlock in support of 4G interface technology, to generate a performance leap. S2500 S2400 not only have all the advantages, and standard maximum 400MB / s high-speed 4Gbps FC host interface, even connect multiple servers, it can achieve high speed response. As a result of RAID6 technology, S2500 in product reliability and availability are a significant upgrade. Increasing hard disk capacity increases, longer recovery time after failure, while the corrupted hard drive is no different from continuous worse. S2500 S2400 inherited the RAID 6 advanced technology, through the double parity, significantly increased the reliability and availability of storage devices. RAID 6 configuration during the user can use the NEC's unique Dynamic Pool function, easy to change the logical disk capacity. Without prejudice to other business situations, the user can smoothly and efficiently as needed to create logical disks.
In addition, S2500 also features mature NEC Phoenix patented technology, the slow response to the hard disk for temporary isolation, automatic implementation of the hard disk scan, such as scanning results showed that there is no fault or failure to change can be restored, then the return to the original hard disk in RAID , thus greatly reducing the replacement rate of the hard disk. Meanwhile, the use of Phoenix technology can slow the server to minimize the occurrence of the visit.

Expand accessibility

According to NEC-related technician, S2500 is a compact, scalable, powerful midrange storage products. With disk prices lower, SATA disk storage application in more and more common, give the user the most direct benefit is realized tiered storage, reducing the total cost of ownership, improved product performance and low cost. NEC S2500 can be achieved within the same array, FC / SATA disk mix interpolation functions that require uninterrupted business operations and high-performance applications, you can use FC drives; for backup applications, you can choose high-capacity, low price SATA hard disk, enabling different based on the nature of business, in an internal storage device to achieve a different division of labor, to help users reduce the cost of backup and archiving.
In addition, S2500 innovation to the controller and disk expansion units can be integrated to the existing structure of compression 6U double, reduced to 3U, significant savings in product placement space. This highly intensive design will not affect the S2500 disk scalability, the basic controller unit, up to 15 hard drives installed. Cascade in the disk of each matching cabinet unit, can be installed up to 15 hard drives, and allow up to 7 disk cabinet to the cascade. S2500 good scalability, enables users to under the business and growth in demand for easy storage expansion, the maximum expandable to 32.7TB of storage capacity and 8GB cache capacity.

Functional diversity

In addition to inheriting and carrying forward the RAID 6, Dynamic Pool, Phoenix NEC storage products such as the unique superiority, S2500 also has a variety of copy functions, in addition to the basic remote data replication, dynamic data replication, snapshots and other dynamic data replication capabilities also increased the dynamic data replication - the dynamic snapshot link function. Through a variety of data replication function in close collaboration, fully meet the low-cost high-speed backup and backup needs. In security terms, S2500 to set the logical unit of disk access, preventing illegal tampering of data. Through the period of protection and to the logical disk unit to write to set the limit to be protected from any server from the logical disk write operation, to ensure data integrity.
The face of fast growth companies changing needs, S2500 high-performance, cost-effective and high value-added outstanding performance in the midrange storage market unique.

Analysis of Taobao in 2008 to adjust the causes and effects of B2C strategy

Such a long time, Taobao's B2C strategy for a major adjustment was finally introduced in the 2008 Spring Festival, which should be to be happy about, but the results made me come out of adjustment conceal his disappointment.

Why Taobao B2C strategy there will be an adjustment? After adjustment for us, what brings buyers and sellers? Taobao B2C future prospects? I think this is of great concern to us all, now three issues to talk about my views.

Three reasons why the policy change Taobao B2C

1, high-level adjustment will inevitably bring about the adjustment of the overall marketing strategy;

By the end of December 2007, Taobao, Alibaba Group, officially announced, senior vice president, Paypal will transfer Taobao president Lu Zhaoxi president and current president of Sun Tongyu Taobao will learn from the cadres, holiday programs, resigned from the current position, enter the study and repair of . Sun Tongyu during employment, Taobao's transaction volume and number of users have been quick to upgrade, but the growth of B2C business is obviously not keep up with trends, warming up with China's B2C e-commerce, Taobao B2C strategy adjustment is inevitable.

2,07 Taobao B2C in the slow development, internal and external causes two knives to promote top of lumbar Taobao B2C in 2008 to seek change;

Back to top of the first knife: Taobao B2C scale of development did not reach expectations, internal pressure. In 2007, the Taobao continued strong growth trend, trading platform increased from from 16.9 billion yuan / year soared to 43.3 billion yuan / year, while

The number of registered users increased 53 million from 30 million. However in 2007 the slow development Taobao B2C and C2C serious imbalance in the ratio of increase. Ma B2C e-commerce business empire is an important part, but in 2007 in Taobao B2C in a relatively awkward position, internal pressure, the plan must change.

Back to top of the second knife, in 2007 the rapid development of China's B2C, B2C plump piece of cake for many businesses eyeing. Alibaba is the leader in e-commerce, however, is Ma B2C e-commerce empire, the most flimsy of a pillar. Expected in 2008 China's B2C e-commerce development will further speed, high-growth market for many companies and opportunities, how to grab a larger market 08 share, is most concerned about Alibaba, if not high-speed growth in China's B2C of spent enough market share, then e-commerce business empire Ma serious weak link. Taobao B2C strategy, therefore adjusted also be ruled out.

3 Taobao adjust the pressure within the business structure

Financial Times "Taobao B2C evolution:" International Trade "model how to get? "Mentioned in the article, Taobao C2C is a flea market in fact, true, but, that is, the" flea "market for Chinese Internet users has formed the habit of online shopping. Can be said Taobao B2C e-commerce development in China's training base, Taobao's transaction greatly promoted China's C2C online shopping transaction size, has cultivated a B2C e-commerce development to be of the first online shopping crowd. However, B2C and C2C completely different concept, the B2C and C2C business on the same platform would have a lot of problems, but also violated the fundamental rules of business so many years. Therefore, restructuring, or even completely stripped out of B2C business, building a new platform to operate Taobao B2C, is not impossible.

After adjustment for us, what brings buyers and sellers?

Alipay and sellers Taobao credit system is the two important factors for success. Similar to the certification system is also a member of Alibaba Ali brilliant achievements to be due. B2C Taobao Taobao C2C is the seller in addition to the introduction of more credit certification conditions, therefore, in terms of buyers, sellers Taobao B2C mall integrity should be higher.

High integrity allows buyers to buy the rest assured that better protect the interests of buyers. The seller must increase input costs, it is also time to get a platform to promote additional assistance, increased sales opportunities, sales costs and product prices have definitely upgrade.

This is the 2007 implementation of an Taobao B2C situation. From 2008 to adjust the strategic point of view Taobao, there are three salient points: first, Taobao B2C seller's access threshold increased; second Taobao B2C brand will be divided based on a single brand lock sellers ; third, to enhance the positioning Taobao B2C, C2C draw clear expectations and boundaries.

First not from the overall strategy is correct, the three points from the strategy view, either the buyer or seller can not do anything new strategy of tangible benefits.

From the buyers perspective, affordable, convenient, secure online shopping to achieve the purpose of B2C and C2C e-commerce is a fundamental value of expression. If the new emergence of Taobao B2C mall shopping for the cost of upgrading to the buyer, and that might make part of the buyer or any other B2C C2C mall to buy merchandise. Although the new B2C Taobao more effectively screen out the brand strength of more formal business, but prices and sincere service to make a decision in time, the market may make buyers choose, or choose low-cost alternative shopping channels. In addition, a point to mention is that, if the seller Taobao B2C locked into a single brand seller, who then in the end it appears in this platform? Brand distributor? Brands?

Considerable size of a single brand Taobao big seller? We consider the fact, that the conditions for a single card brand management are established to meet the conditions of access Taobao B2C mall's also willing to enter, few sellers.

From the seller perspective, operating costs are often directly linked to the price and product, but product prices and sales volume and profit has linked Taobao B2C increase barriers to entry allow many vendors to consider another path.

On the other hand, from the success of e-business models in the world seems to be a single brand management and most successful brands, and I said, success is integrated in the success of the brand + marketing, not just the sales platform . Seller

Map is profit, single brand management style is considerable. Suppose, if the achievements Taobao B2C businesses after a certain size, how to handle the brand of traditional channels of distribution channels and networks is the relationship between the manufacturers, distributors, agents can not tell between the endless number of complex relationships the.

Taobao B2C future prospects?

2007 Guangzhou Expo in commercial software when ProBIZ sfotware (probiz.cn) consulting analyst pointed out: With the constant expansion of online shopping, e-commerce entity + network marketing model will become the mainstream. That is in addition to many of our growth and fledgling C2C sellers, the number of traditional companies will cut into the B2C e-commerce, and through its own funds the rapid rise of scale advantages. Therefore, Taobao is much room for future development of B2C.

The future model Taobao B2C will happen? I expect that, stripping out the establishment of a dedicated business B2C trading platform is more suitable for B2C business model aggregation platform. The platform is a brand division of business or to sell the product key to type into the platform business is willing to type. In addition, the effect of traffic aggregation Taobao B2C platform is the core of the service and traffic if the two issues to find the best answer, then Taobao B2C platform will be a good development. And more large and medium enterprises may attempt to establish autonomous B2C e-commerce sales platform, this force will be the mainstream of the future development of B2C.
