Whether to buy a server or NAS

NAS is just very simple to add a NAS storage in a local area to achieve storage, but there are many details in it that I don't know much about. NAS In the cases I have been exposed to, the client will not consider using it and will not bring it up.

Using IBM X3650M2 (2-way server, 16 memory slots, 12 hard disk interfaces, and can be expanded through PCI slots) The first thing you have to care about is what the maximum capacity is, 300gx12 = using RAID10, the fastest speed, completely fault-tolerant, each group of RAID1 can break one disk, up to 6 hard disks can be broken without data loss) = actual capacity.

RAID can be used in other ways, RAID10 is the best choice, but ** is relatively high, you can also choose RAID50, but in the same group of RAID5, the data of 2 disks cannot be recovered. The 2-way server and 16 memory slots are fully considered for the development of your enterprise in the next 3-5 years, and the performance of the server can be improved by increasing the CPU and increasing the memory.

The same is true for hard disks, if the data growth rate is not planned to be increased within 5 years, the number of hard disks can be reduced to get the most cost-effective backup software. It is recommended that you use Tivoli Storage Manager to directly set the policy to implement global backup through LAN at the fixed time of the finger solution. You can set any time to avoid congestion during business hours.

Needless to say, storage space is a must.

1.Cross-platform file sharing and access to mobile devices such as Windows, Mac, Android and iOS. This is to facilitate file reading and sharing, which is a bit inconvenient if you don't support cross-platform.

2.Remote access, equivalent to a personal cloud storage host, can be accessed to the home NAS through 3G or network outside, for file uploading, **, and management. Basically, if you meet these requirements, you can call it the most basic household NAS.

It's also very simple to meet the requirements, the network support at home, a router, and a computer. Software required: FreeNAS (available on the Internet, free NAS system) This way to build a NAS has few functions and consumes a lot of power.

High maintenance costs in the later stage. If you want to use it for a long time, the cost is no less than buying a finished NAS. First of all, in terms of maintenance difficulty, NAS is actually a Linux computer that inherits the CPU, this sentence is true, but NAS's Linux operating system is embedded in the DOM disk, so it is excellent in terms of stability and antivirus, and the Linux system used by NAS is a thin system, that is to say, it eliminates the functions that are not needed to ensure the stability of the system.

If it is used as a data storage, it does not need to be upgraded and maintained regularly, it can be used after simple settings, and NAS also comes with RAID function, which can ensure data security, and the data backup function is very perfect, whether it is local backup (PC backup to NAS) or remote backup (backup to remote server or NAS), it can be completed through very simple settings, very old and easy to maintain, even if you don't know much about computers, you can complete maintenance. Data security is very important, and NAS such as access control is also very good. The finished NAS is basically maintenance-free.

And now QNAP's NAS is very powerful, for example, with the QNAPHDstation, it can make QNAP's NAS a surprising multi-**** device. Install the free HDSander and connect your NAS to your big-screen TV via HDMI, and you'll be able to enjoy a great visual experience with a wide range of movies, **and**, and surf the Internet on the big screen on your phone or tablet.

NAS is networked storage that implements data transmission based on standard network protocols, providing file sharing and data backup for computers with various operating systems such as Windows, Linux, Mac OS, etc. in the network.

NAS meets the needs of small and medium-sized businesses that want to reduce storage costs but can't afford the high cost of a SAN, with a fairly good performance** ratio.

First of all, it is necessary to see whether the core business of this unit is built on some kind of information system, which has high requirements for data security.

Secondly, it is necessary to see whether the information system already has or will have a large amount of data to be saved, and the degree of data management is required.

Finally, you can also determine whether there is a heterogeneous platform in the network, or whether it will be used in the future. If the answer to one of the above questions is yes, then it is necessary to focus on using NAS devices.

Network storage is like a computer terminal with only storage functions, which can work independently, the system is solidified, and can be configured independently, some need to be connected to the server or computer for setting up, and some can be directly configured. Some traditional wired NAS requires special settings for server environments, but you don't need to install the system yourself, and the setup process is exactly the same as that of a router. For servers, the popular network storage is basically in the form of a network neighbor, which can be used as a local disk if you set up a mapped network drive.

1.The computer system is on the hard disk that is susceptible to viruses in general.

NAS is stored on the DOM disk and is not affected by these images, so it is more stable and more secure.

Generally, it has RAID function, that is, redundancy, which can prevent the loss of data due to hard disk damage in the case of multiple hard disks.

3.Embedded with various protocols, support window, linux, mac, mobile phone access, ordinary systems are not good to do this, so the sharing is better, 4If there are dual network ports, the internal and external networks can be realized, and the setting is simple.

5.Embedded with various functions such as server, FTP, database, sharing, VPN, etc., fool-like settings, saving a lot of trouble in setting, so the operation is very simple.

6.Based on some of the above. Therefore, NAS is easier to maintain than computers, with low maintenance costs and low power consumption.

7.It's also quite versatile, so let's hit it first.

8.In fact, NAS hardware doesn't have much money, the key is technology.

Pure hand-playing - means that it is really much more convenient to have a NAS.

You can also do it yourself with a regular computer, but the stability and power consumption are much worse.

It is mainly used to store user data and encrypt data.

Convenient for users to transfer data Convenient for remote transmission.

It is mainly for the company to protect important information, such as tax, advertising and other information, the function is equivalent to the computer that is always connected to the Internet, and the data will not be lost

Because NAS storage saves important data, the requirements for data security are relatively high, and the reliability of regular NAS storage and product hardware cost is not comparable to that of PC motherboards doing RAID, so it will naturally be more expensive.

It has the characteristics of high performance, ultra-quiet, ultra-power-saving, ultra-environmental protection, etc., with a maximum storage capacity of 8TB, and can support RAID 0, 1, 10, 5, 5, 5+ hot standby and other array levels and single touch backup, disk partition snapshot, incremental backup, remote replication and other functions, and is an entry-level solution for home digital storage, SOHO office and small and medium-sized enterprise network file sharing storage.
