Preface: The dedicated storage server has become a market trend company to create a complete storage platform to meet its future high-speed growth, it is necessary to use a set of effective ways to evaluate and consider. In particular, the NAS storage market is almost increasing, and the meaning of the company is not very significant. Therefore, companies should not just be based on the purchase of NAS hardware, but to plan to assess what is the most consistent The needs of the company itself can integrate the current storage environment of the company, using a set of most complete standard storage solutions. The survey report of the global storage market pointed out that there is less than 90,000 sets of online additional storage (NAS) in the global market, only 100,800 sets of business server in the Chinese market, and if they add 22,000 sets of markets in Taiwan, Will be much larger than NAS in the global market. In fact, Microsoft's market is the market, Windows Powered NAS is renamed for Windows Storage Server 2003, which is to change product positioning, emphasizing the application on storage. The positioning of Windows Storage Server 2003 is an integrated platform for a network storage program, which is a true purpose of the enterprise adopting storage devices. Windows Storage Server 2003 is used to integrate the internal storage environment of the company. First, the first integration is the disk array (IDE, SCSI, fiber), the second is to integrate different servers (Exchange Server, SQL Server, web server) The third is to integrate the enterprise heterogeneous network environment (UNIX, NetWare, Macintosh). The intelligent central Windows Storage Server 2003 (Figure 1) of different connection devices, is a common cooperation with OEM / ODM's famous major manufacturers. On the basis of Windows Storage Server 2003, it is possible to meet the company's disk arrays, servers and heterogeneous networks at the same time. The five major storage solutions for different storage solutions such as environmental storage. Windows Storage Server 2003 provides a software-backed network storage product that provides software and hardware with Microsoft's OEM vendors, and does not sell separate software disc installed separately. Users can refer to the storage scheme of Windows Storage Server 2003, which is the hardware and hardware combined with each OEM vendor for a variety of different applications.
Figure 1: Windows Storage Server 2003 is a perfect integration platform Windows Storage Server 2003 why is a storage integration platform? What is the difference in the company? In fact, Windows Storage Server 2003 is a standard platform with powerful storage software computing capabilities, with various storage hardware device connection capabilities. Because it solves the problem of storage applications and management of disk arrays and server matching in the current enterprise environment, the purpose of Windows Storage Server 2003 is to support server and disk arrays, and can solve corporate storage applications and management issues. . By the Windows Storage Server's software computing ability to place the data in the most appropriate storage space, such as IDE, SCSI, fiber disk arrays, different tape drives, or a large-capacity hard disk of Windows Storage Server 2003 itself. How to choose the best storage solution To understand the crux of the enterprise storage problem, Microsoft will recommend that the enterprises ask some of the five questions, which is to provide a method of storing environmental self-diagnosis of enterprises. You can see this way. What is the current encountered in the enterprise storage environment. First of all, the first step is to ask what the server environment inside the company is? Enterprise generally more important servers have only three types, namely mail servers, database servers, and web servers. What are the versions of the server and the number of brands, you must do some basic understanding. As for why you want to start from the server, it is because the server is equipped with a disk array, and those disk arrays must also be used by the server, so I have to understand the use of the internal disk array of the enterprise, how much is it? It belongs to the Fiber Channel, how much is SCSI and which is Ide. After you understand the status of the server, you'll see the matching relationship between disk arrays and servers. See which servers are used by the disk arrays of the fiber and SCSI, and it is important to understand these storage devices. Space, where the remaining space on which disk arrays is too or too small. Then you have to understand the use of business backups. I understand that the old DLT tape is now used or a new tape library. In addition, it is necessary to understand the backup method, there is a backup software that uses other vendors. The last is to understand the company's file server, because it is the most popular storage device in the company. Please pay attention to its job environment version, there is no upgrade demand? Do you need to centrally manage? Do you need to do file sharing with partners outside? Do you need a regular backup for these files? After you have finished the above questions, I will decide what kind of storage equipment scheme that needs to be needed in accordance with these conditions. In general, there are five problems, the first is the server, the second is the disk array, the third is the matching relationship between the server and disk array, the fourth is the method of use and the current situation, fifth One is the case of the file server. After asking these five questions, there will be a preliminary answer, and prepare to solve the problems faced by the enterprise, which is the appropriate solution to the next thing to decide. Storage Gateway - Regeneration Server and Disk Array Storage New Apply Windows Storage Server 2003 is best suited for Storage Gateway. Because WSS2003 can manage different storage devices such as disk arrays (fiber, SCSI, IDE), tape libraries (tape, tape library). It also integrates the heterogeneous network environment (UNIX, NETWARE, AppleTalk, the server (SQL Server, Exchange Server, Web Server) is fully compatible.
When is the company suitable for using Storage Gateway? In fact, it is applicable to two timings, and Storage Gateway is mainly used to solve the space inadequate and space in space. Space is usually on the fiber disk array, while the space is insufficient to occur local hard drives in the general server, or on the SCSI hard disk of the early capacity. Corporate often seems to keep up with the speed of storage, so some companies will spend money to buy a fiber disk array, but because the unit cost is too high, it will not be able to put a lot of data above, and finally become just let It is idle, and it is not found to use the method of proper use. So Microsoft puts forward the Gateway solution, this time Windows Storage Server 2003 is a very standard Storage Gateway. Why can I do it, there are three reasons. The first reason is the core of Windows Storage Server 2003 - it is using Windows Server 2003, in other words, it is a standard operating system, and there is no problem on all storage hardware support on the operating system, no matter which Brand, as long as it has the driver of Windows Server, and various disk arrays can also be supported. If you want to connect the Fiber Channel, just connect to a fiber channel card, so support most hardware support is compatible. The second reason is that companies need to connect to various heterogeneous platforms, and the support of Windows Storage Server 2003 has no problems, including UNIX, NetWare, and Macintosh. So small to a design company uses Macintosh's network, and it is possible to use UNIX's network. Windows Storage Server 2003 can support.
Figure 2: Gateway integrated storage space If the storage of the company is excessive space, Figure 2 is to pull the unused space out of the IP network with Gateway, may ask, why Do you have to do this? The reason is that it is impossible to connect directly to the current Fiber Channel in SQL Server or Exchange Server, then take it as a file sharing and backup service, so we can connect it to the IP network, and this Gateway is also There must be the ability to apply because it is not just a network cable, but a network connection platform. Windows Storage Server 2003 is best suited for the third reason for Gateway because of the most storage software on the above, because the relevant software that supports Windows Server 2003 can also support WSS 2003 at the same time. The Windows Storage Server 2003 releases the true unused storage space as a richer storage management app on the IP network, to address the storage management issues of different servers, including web servers, file servers, Exchange Server , SQL Server, and numerous users PC. So it is clear that the purpose of Gateway is to connect the server with the storage device and the heterogeneous network, then enhance the storage architecture, communicate with PCs with PC, and select the source of storage data. Store in the most appropriate storage device. This is to completely solve the most important principles of enterprise storage management. Exchange Server Storage - How to enhance Exchange Services How to improve the performance of Exchange Server? Because in Exchange Server, the original problem is that it must perform two work. The first item is to provide the user mail mail service (mailbox), the second item is the action of the IO and Hard Disk Switch (SWAP) of the data store. So the burden on Exchange Server will be heavy, which is also a problem that the company is generally concerned when using Exchange. The architecture provided by Microsoft now is to separate the database, allowing Exchange Server only to provide email services, as for the IO and hard disk exchange of the database to handle Windows Storage Server 2003 (Figure 3).
Figure 3: Improve the performance of Exchange Server now is simple, just add the Windows Storage Server 2003's Feature Pack, install it on the Exchange Server 2003, you can directly store the Exchange server database through the IP network in Windows Storage Server 2003. There are three benefits above: The first is to improve the performance of Exchange Server, because it does not need to do the database's IO and hard disk exchange, which also reduces the cost of CPU resources, so it may have a 500 mailbox, It is now available to 700, 800, and even thousands, saving the upgrade investment on the hardware. The second benefit is because the database has been separated, so don't worry that you will affect the performance of Exchange Server itself, MIS people don't have to worry about the performance of the server when backing, and Microsoft can also use mirror (mirror) Method, or back up with a conventional disk drive, protect its data, and improve the performance of the Exchange server. The third important benefit is that when the Exchange server is disaster, this architecture recovery ability is the fastest. If there is a new Exchange Server, the MIS personnel can continue to provide the original service as long as the MIS personality is resourcely resold. And when you upgrade, you can upgrade in a non-stop, it is easier to expand the new Exchange service. In summary, because the architecture of data separation is implemented, the data of Exchange Server is stored on Windows Storage Server 2003, so you can make a backup at any time, and will not affect the performance of Exchange Server, and can also be able to have problems in the system. Rapid recovery system.
SQL Server Storage - Make sure the SQL Server never stopped the basement of the database is not recommended to use the file-level approach to the separation of the database on SQL Server, because Microsoft does not provide related tools (such as Feature Pack), so it is recommended to use iSCSI with block Ways, but to apply iSCSI on IP network, you need to install Microsoft iSCSI Initiator Driver on SQL Server, you can make SQL Server's database directly from the local disk as long as you are installed in any Windows 2000 Server. Separate, store the data on the other end by IP network. Target can also be applied to Windows Storage Server 2003, and now there are other vendors (such as falconstor) launched a complete iSCSI Target software. The reason for Microsoft does not provide iSCSI Target is that it is not just a simple driver, but it is already The application of a complete iSCSI storage scheme. When the database is separated, placed on the Gateway of Windows Storage Server 2003, the first one you want to do is to do iSCSI Block's snapshot (Snap Shot), or directly using other manufacturers' tool software to make it mirror to another. Disk arrays or back up to disk arrays, through the combination of iSCSI, which can also be integrated with SAN, so this is the IP network ISCSI and Fiber Channel SAN combination. With this architecture, you can support all different brands of databases, including Oracle, Sybase, and DB2, you can also expand the mail server supported on the Windows platform, whether it is Lotus or Exchange 5.5 / 2000, as long as it is running on the Windows platform, Database software and mail servers supported by Windows 2000 Server have no problem. By free Iscsi Initiator Driver, you can place SQL Server's data inventory on Windows Storage Server 2003, which in addition to the data storage performance of SQL Server (as shown in Figure 4) in addition to the backup of the SQL Server, in addition to the data storage performance of SQL Server. The minimum impact is the shortest disaster recovery time. And when there is a new application to be tested, you don't have to first back up the data, then install it on another machine, just place the data image, install the iSCSI Initiator Driver on the test machine, you can omit the past needs The length of the backup recovery data is restored.
Figure 4: Improve SQL Server Data Storage Performance Backup Gateway - Select the most suitable backup storage device Windows Storage Server 2003 Built-in Backup Tool, able to support Exchange Server, SQL Server, Web Server, File Server, such as Veritas, Ca, Legato, etc. Backup software. In addition, Windows Storage Server 2003 contains the Robocopy tool that directly supports the client's data backup. From the backup method of Gateway, when the data is backed up to Windows Storage Server 2003, it is also equal to the backup to the backed disk array, because the backup to this side can be used as a cache, then back up to other tapes Storage media. Another part that is easily ignored by the company is a data backup for client users. Microsoft provides a tool called Robocopy, which can be installed on the user's PC, then make incremental backups for the folder specified by the user, due to only This is enough for a part of the data for the data, so this is enough. Because of the general user, I don't know which data has changed. Therefore, all copies are usually copied, and it will be wasted for a lot of time, and now just give this tool (as shown in Figure 5).
Figure 5: File storage with high-speed backup and recovery function Document Storage - Upgrade file server stores data on Windows Storage Server 2003, you can bring powerful file snapshot backup, file sharing and file security control . Most of the current companies have existing backup solutions. In fact, the purpose of the storage solution is to solve the space insufficient, and provide the fastest way to recover the data fastest. The Document Storage is the high availability of the company with files, which is also a file fault-tolerant storage. If the file server is very important and requires the HA function, the company will build two Windows Storage Server 2003 as a file server, and then enable the user to reach a path failure when using built-in DFS technology. Another function can be automatically taken (Figure 6). Windows Storage Server 2003 also allows users to do their own file protection because it has the function of shared folder shadow copy (SCSF), and users can operate their own operations through the resource manager and no longer need MIS personnel operation settings. The advantage of this is that the file can be automatically backed up, and the file is accidentally deleted will not be lost, and the file server itself can make a snapup backup. For the interface shared by the file web, Windows Storage Server 2003 allows users to share files through HTTP or FTP, even if they are shared to the outside partner, as long as the user can use the account and password Data can be accessed directly using the resource manager, so that all files can be controlled to control on the server, and HTTPS is also supported in terms of security, and the file can be accessed, more Safety. As for the file security control, Microsoft has more powerful technologies, which can set the permissions that you can access for a single file, and the settings can be set on the folder, so that users can deposit into files, but Can't open and browse this folder, this way is like something to put in the safe, you can't see it, which is important for the control of some security inside. In addition, Windows Storage Server 2003 has also added storage management software for Storage Manager 2.0 (optional software). It mainly has three functions, file screen screen, directory quota, and storage space use report, respectively. Storage Reports. Let MIS personnel can use file filtering, setting up server monitoring and disabling file types, such as images and audio and video files that should not be stored, and directory quota management functions are capable of managing and controlling all shared files that can be used on the server. The space of the clip, storage space use reports can analyze the application situation of the disk, so that the system management can understand which files are most commonly used, and the hard disk space usage.
