What are the advantages of a storage server?

One. Good quality and low price, two. Technological diversification, III. The quality of the equipment is stable and secure, and the storage server is designed for a specific purpose, so the configuration is different. It could be a server with a little extra storage or a server with a lot of storage space.

1. If you find that the server data is lost, Qiancheng should no longer operate blindly to reduce the probability of data recovery. You can find technical support from a regular data recovery company through **.

Listen to proprietary advice or have it checked by a professional technician. At this point, you can shut down the hard disk to stop reading and writing data. No more writing data to the partition or hard disk where you lost your data.

Reduce secondary damage. 2. Always pay attention to the operation status of the server hard disk, and observe the server hard disk indicator light. Generally speaking, the appearance of the server has each hard disk indicator, which is generally green under normal circumstances, and when the indicator light appears in special circumstances, relevant measures need to be taken to carefully check whether the hard disk equipment is normal.

Once the hard drive is damaged or data is lost, don't lie and make sure to keep a cool head. 3. The server storage system is very important, as we all know, the hard disk is the main equipment for server data storage, and it is also a high-tech, sophisticated manufacturing equipment, the development of server hard disk has reached 10,000 revolutions per second or 15,000 revolutions, ordinary SATA hard disk.

It is also very close to this speed, in operation, a small fault may cause physical damage to the hard disk, so the general server uses RAID disk array storage to strengthen the fault tolerance function of the server hard disk. Other servers like the billion-gram server are easier to use, with high cost performance and more stable performance. [If you are interested, please click here to learn more.] 】

Hello, I am an engineer at Dell (China).

As for the issue of your company's server procurement, you are too brief to describe, I can't make a precise decision, and I recommend choosing the right server for storage from the specific application and budget of the server.

You can copy your question and send it to my mailbox, please try to describe the problem as close as possible.

Indicate your city and contact in the email** and I'll call you.

I can give your company a reasonable plan and suggestions from the technical and ** aspects!

The server can be the server host plus the server storage, that is, the hard disk;

At this time, the server and storage are integrated, in addition, it is the host of the server alone, and the hard disk on the server is generally only used to operate the system safely, and the server is the server;

Storage is a stand-alone device, typically in the form of disk arrays, tape libraries, shared storage for small environments, and so on;

A server, also known as a server, is a device that provides computing services; Since the server needs to respond to and process service requests, generally speaking, the server should have the ability to undertake and guarantee services;

The composition of the server includes processor, hard disk, memory, system bus, etc., which is similar to the general computer architecture, but due to the need to provide highly reliable services, it has high requirements in terms of processing power, stability, reliability, security, scalability, and manageability.

Storage is to save data to certain media in a reasonable, safe and effective way according to different application environments and ensure effective access, generally speaking, it can contain two meanings, on the one hand, it is a physical medium for data to reside temporarily or for a long time; On the other hand, it is the way or behavior that guarantees the integrity and security of data.

Storage servers are designed for a specific target and are therefore configured differently. It is possible to have additional storage, or it is possible to have a server with a large storage space.

Some people think of a storage server as just adding some features to a server, some define it as a plain box dedicated to a specific function, and still others think that the term should refer specifically to NAS devices.

Storage servers are usually self-contained units. It is sometimes designed as a 4U rack mount. Or two boxes consisting of a storage unit and a server located nearby. The two boxes can then be installed in parallel in the cabinet.

Server memory is also memory, it has no obvious substantive difference from ordinary PC memory in appearance and structure, mainly in the memory of the introduction of some new unique technology, such as ECC, chipkill, hot swap technology, etc., with extremely high stability and error correction performance.

Server memory is the same as PC memory, and the frequency of the memory can be expressed in two ways: the operating frequency is the actual operating frequency of the memory particles, but since the DDR memory can transmit data on both the rising and falling edges of the pulse, the equivalent frequency of the transmitted data is twice the operating frequency.

DDR2 memory, on the other hand, is capable of reading and writing data at four times the operating frequency per clock, so the equivalent frequency of transmitting data is four times the operating frequency.

There are many types of servers, storing data is only one of the functions of the server, any server has the function of storing data, and storing data is the most basic function of the server.

In terms of functions, there are database servers that store data, servers that store files, servers that provide computing, game servers, mail servers, web servers, and so on.

According to the application level, there are entry-level servers, workgroup servers, departmental servers, and enterprise-level servers.

Different servers have different functions and different positioning.

For example, if a small and medium-sized enterprise has dozens of computers, and employees need to access some files and data for office, then a server needs to be set up and files and data can be placed in the server for employees to access and call at any time. This server can be connected to the WAN and only serve the company's internal service personnel. It is also possible to access the Internet and provide network services.

Compared with the PC, the server is larger in scale, more functional, stronger in overall performance, has more processors, larger memory, and the storage capacity is huge, and can be expanded at any time, expanding the processor plus memory and hard disk, etc., the server is actually a computer, and it is also made of CPUMainboard. Memory.

Hard disk. Operating system. There are generally no monitors, as the servers can be controlled remotely by maintenance personnel.

The processor of the server is generally multi-core and multi-threaded with low frequency, because the service has to cope with the access needs from multiple parties, and the multi-core rock history and multi-threading can handle multiple tasks at the same time, and the server is generally turned on and running around the clock, which must be stable, reliable and easy to manage and maintain.

In fact, the web page that is generally opened on the Internet is also called up from the server, and a web page exists in a folder in a certain server, and there are often a lot of characters behind it, which is actually the location of this file.

There are servers that specialize in providing computing tasks, such as some giant machines that can provide open, remote, large-scale computing, and are specialized computing servers.

A router is actually a kind of server, but the function of the router is relatively single, responsible for data ** and address translation.

An ordinary computer can also be used as a server, for example, if you build a ** and store some files and data. The public can access your ** or ** certain files over the WAN, and your host becomes a server.

Servers typically have a disk array of many hard disks, which can be stored in large quantities and can be expanded at any time. Like the previous personal homepage personal space, the current cloud disk, the rented ** storage space, etc. are all servers.

Those large Internet companies have built a number of huge data centers, the so-called data centers are actually composed of servers, data centers are mainly used to store data, the data center serves ordinary netizens, netizens can access a file in the data center at any time through the Internet.

There are differences in function and role.

1. A server is a computer that centrally processes client computer requests by providing various services, such as file transfer, printing, email, web services, etc. A server provides data resources to multiple end users and is a complete computer system, usually with a complete set of hardware components such as an operating system, application software, processor, and memory. Servers can also be used to store data, but storage is often an add-on to the server, not its primary function.

2. Professional centralized storage is a special device, which takes data storage as its main purpose. Unlike servers, it typically doesn't have a full operating system and software applications, and only includes the necessary hardware and operating system to improve storage speed, scalability, and security. It contains a large amount of hard disk or memory and provides access to the client computer via a network connection.

Professional centralized storage can be connected with multiple servers to provide a system.

1. Reliable data storage and backup function. It can meet the demanding data storage needs of enterprise data centers, cloud storage, and large databases.

Therefore, the design ideas of the two are different.

The purpose of the server is to provide data processing and services to multiple users, while professional centralized storage only provides data storage capabilities and is designed to improve data reliability and availability.

1. Server memory is mainly used to store temporary data and use it for caching. The server system itself occupies less memory, and the amount of memory required depends on the applications running on your server.

2. In theory, the larger the memory, the better, you can put more temporary data into the memory, to avoid directly reading the hard number of the disk, after all, the speed of reading the memory is much faster than the speed of reading the hard disk, but from an economic point of view, it is good to use enough, more, the server is not used, and it is wasted there.

There are two situations for server storage, one is because of the hot standby of two machines, and the other is because the amount of data stored is relatively large, and the hard disk inserted into the server cannot meet the demand, and the storage is a cabinet that can insert a lot of hard disks, we all call it a disk cabinet, dozens of hard disks constitute a large storage, and the server is connected to read data through accessories and storage.

The server can be: Server Host + Server Storage (Hard Disk) At this time, the server and storage are one.

In addition, it is the host of the server alone, and the hard disk on the server is generally only used to operate the system safely, and the server is the server.

Storage is a stand-alone device, typically in the form of disk arrays, tape libraries, shared storage for small environments, and so on;
