NAS and SAN have become the protagonist of the storage manufacturers who are not good for stories, almost all overnight. The storage market originally like the March of the spring, under the downturn of the trend, and got an early morning, the fascinated "Advanced Technology" is going forward, but if there is anything wrong again ...
Recently, the NetWork Appliance Vice President Patrick Rogers brings new technologies for "Open ILM". Like the storage mesh, storage virtualization, etc., another new concept of the storage industry is born. This company has a very high share of NAS market in North America. It is currently claiming to resolve the "storage integration, data center operation, business continuity and distributed enterprises" and expand its leading position in storage meshes. . "Open ILM" is a fully open infrastructure. In NetApp's architecture, such as NFS in the UNIX environment, different manufacturers can pass through the API ports through the API port in the Windows environment, and use the ILM server. The return of data is migrated to realize real ILM technology. Patrick Rogers said NetApp will fully promote this application. Information lifecycle management is ILM, is the popularity of the current storage industry, accurately, is "hot" that stores mainstream providers. Its initial proposal is STK, now EMC is in love. In February this year, EMC convened numerous integrators, distributors and industry users in Beijing. On the release of EMC Symmetrix DMX, CLARiION CX, Celerra and Centera Systems and Software New Version, how to deal with how EMC helps users use EMC's ILM management The model got the maximum value for the user, and then published the book "Information Life Same Management". ILM is a beautiful "technological idea" that is said that IBM has long been able to process ILM tasks. However, in the eyes of domestic customers, like memory mesh, smart storage, storage virtualization, etc., ILM is still a symbol, which is still unable to universal applications; even, their actual applications have begun to be quoted.
Storage requirements
In the domestic storage market, ILM has not been caught in the "public opinion" crisis, and NAS is being encountered in the "low-end network like PC" vortex. The so-called 何,, 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理 理. But how many customers will pay for those storage concepts that "look also beautiful"? Some people say that the concept is the trick used by the manufacturer, and the customer is also happy to follow the style. One is willing to fight, one is willing to swear. This is also the application reflected in the "storage network". The storage network environment for mixing applications is extremely common. In a bank office network in the north, the HP and IBM hosts will be added to the EMC disk array, which increases the 10K band library of ADIC due to the year-on year of business data. Moreover, in the huge IT system of enterprise-class users, there will be a variety of operating system platforms, such as bank data centers may be OS / 390, the provincial branch's large pre-system is IBM AIX or HP-UX, branch The system may be a Windows system. The customer's business system is multi-platform demand. The concept of "unified" storage is tonally. Si moves out of the current most popular SAN or NAS, appearing. Excellent Technology (China) Senior Storage Technology Engineer Liu Guoliang explained that storage network needs a certain amount of funding, mainly for purchase SAN fiber switches, network storage devices, and related management software. If the customer's system is very simple, there is no need to store networking modifications (that is, maintaining DAS original). If the customer IT system is more complicated, there are multiple servers, storage devices, etc., I hope to implement the integration of data and storage, that Using network storage techniques for transformation. Liu Guoliang is responsible for the storage solution planning of the project, including all SAN network planning, disaster recovery, data sets, etc., etc., etc. His analysis is the same as other storage professionals. The only difference is that the enthusiasm is a brand product of its own agent. For example, a distributor in Shenzhen is the regional agent of HP. When they recommend "the most appropriate front-end technology product" to the customer, the HP's products will be broad and degrade other brands. This is why the current storage agent or Si can not be released by the manufacturer. And the procurement criteria for major customers such as government, telecommunications, and finance are not the most "advanced technology". This is also one of the reasons why the storage market is in a germination period. When the agency talks about the "storage network" essential condition, they simply summarize them into three conditions: First, the customer must have money; second, customers should recognize the manufacturer's products; third, manufacturers have more publicity. There are no other secrets other than this. Technology is not equal to occupancy
For users, "concept" voices and applications always have a layer of yarns. Therefore, there is only the sales volume of domestic HP accounting for the first market style; the EMC of many patents and storage technology is the representative manufacturer of storage technology, but the market share is not boss. In the current storage brand market, Fang Hongbo, the technical director of Shenzhen Donghu Storage Technology Co., Ltd., is analyzed in hard disk technology, IBM is another technology provider, IBM and HP, the company, IBM and HP, how completely, The overall advantage is obvious; the advantage of EMC is in high-end disk arrays. If the product performance is as follows, all home is not up and down, thereby there is a fierce competition between the EMC DMX 8000 series, IBM F800, HP EVA5000, HP EVA3000 series. Dell and HP have had a huge marketing network, which has completely occupied the market through OEM advanced technology products. According to Changsha Tianchen Science and Technology Storage Technology Engineer Wang Wei analyzed: At present, high-end server manufacturers such as HP and IBM account for the advantage of the first, and old customers such as telecommunications and finance are also in their storage camp; they absorb all kinds of advanced technology majors The storage device manufacturers provide OEM, so-called one-stop service, the province has troubles and risks that customers have deal with different manufacturers; except for EMC, special storage business. Therefore, EMC changed a "joint brand" way, working with Dell. EMC China Market Director Du Guoqiang introduced that EMC & DELL combined brand promotion plans, the cooperation between the two sides will extend globally to 2008. In the interview, those professional storage technology salesperson with customers have played for many years, and the "storage mesh" or ILM propagated by the manufacturer is extremely indifferent. The root causes that they understand that users should consider, whether they need to spend more than one million yuan in an extension of a SAN. They will not be full of new technologies that manufacturers invisible. IP SAN era?
NAS is a system with "Plug and Play" style, has been very attractive, and therefore summoned a large number of server vendors into this field. It uses Mature Ethernet IP network technology in the LAN, which means that files can be shared between more servers. The emergence of NAS once makes domestic server vendors found new "propositions" - providing users with a unified storage system. Now, SANRAD from Israel claims that it is necessary to break this so-called storage application to deliver truly simple IP SANs for domestic customers. This company began to enter China in July 2002, is currently actively interested in many domestic storage equipment and has taken a step by one by one. It is said that SANRAD may provide OEM for the world's largest SAN. Huang Daozhen, director of Sanrad China, revealed that he had experienced a series of training with many companies in China, including Lenovo, Founder, and Wave. Prior to this, they also had certain storage technology with 50 such as Daxheng, Tsinghua Histle, and the latter strength, and its storage business is like a chicken ribs. After that, all disk arrays, which are all doing disk arrays, have made technical tests on Sanrad products. According to Huang, the price of ISCSI SANs in SANRAD band management and 1TB disk arrays is only 200,000 yuan, or even as low as 150,000 to 80,000 yuan. Such a seductive architecture allows those enterprises that think to build SAN spend 2 million yuan, can you not be? With yellow view, currently, people's investment in storage systems is difficult to benefit from technology, and the so-called object cannot be used. It should be said that all storage work is expanded based on the DAS-based computing architecture; file applications are completely removed from the storage architecture, and should also give the company data a clean storage network.
Who is the first to eat crabs?
Independent storage network applications have been exclusively host manufacturers including IBM, HP, Sun, SGI resistance. But the emergence of simple IP SAN in front of you can't stop. At the beginning of the year, SANRAD equipment has successfully applied cases in domestic e-government, education and military users. The current Microsoft is vigorously pushing iSCSI, based on these successful applications, the cooperation of SANRAD and Microsoft seems to be. "We believe that CPU and memory should modular, large-scale production, the most important thing is that software is managed by the memory, tune the memory to meet the needs of the application, thus achieving the purpose of the network's transformation of the data center, Huangdao It is necessary to speak in the statement. It seems that users can only put the memory of the memory function in the network, and only need to buy a storage function, without having to buy a general host's money, can achieve effective management of cross-platform data. So what is the idea of the industry? Wang Wei believes that SAN and NAS have become mainstream technology in the storage market, and the main architecture of the customer IT system construction (SAN is divided into IP SAN and FC Fiber Channel SAN). "IP SAN is now almost no market, and it is also the stage of hype. It is a big customer, which is a big customer, rich master; while small customers rarely consider specialized network storage, current application status," middle The layer is very large, the demand is not excavated, belongs to the "fault", he said. Wang Wei said that "intermediate layer" said that a large part of the medium-sized middle customer has no high requirements for storage, very few Buy a single. Such as the high-end customers of the provincial telecom and bank classes do not consider the cost to buy the highest-end hardware, software and service storage management systems; such as small-end hotels, retail malls, etc., low-end customers, may buy some very practical small Equipment and cheap memory. Like all of the storage professionals who are full of IP SAN, Wang Wei is completely denied against "IP-based SAN has entered the application phase". Agency mostly believes that IP SANs within three years, such as iSCSI cannot be large The scale is popular. The products of the manufacturer are still in the test stage. There is not much customer is willing to be the first to eat crabs. Based on the traditional FC fiber SAN itself is constantly evolving, whether it is still, the high-end customer group can only consider the fiber San. Optical fiber The channel has an unparalleled advantage in large-scale storage data throughput. It is like a large-scale machine in the 1960s that has not been used in key commercial applications. Trend and application contradictions are difficult
