Server disconnection guide-how to build a Test Platform

With the rise of private cloud and public cloud (such as the big Microsoft private cloud and Microsoft Azure), as IT people want to experience their charm, they need to pay a lot of money to buy a large amount of memory, provides powerful computing servers.

I believe that more students who focus on and learn technology will always be concerned about cost-effectiveness. It also needs to reflect the power of the server.

This article will share with you "server-bound", so that you can spend less money and do more things. Only when there is more will there be more prospects in the future.

First, let's draw a few conclusions. This is also the basis of this article:

1. The cyst is shy or doesn't want to spend too much money on the server.

2. If you want a machine with strong performance, intel's new platform is too expensive.

3. Intel Xeon series.

We have always been concerned with servers and workstations. In fact, is the server's computing performance necessarily stronger than that of home machines? Not all, many home machines can overclock, but servers can only reduce the frequency and not exceed. In addition, the CPU and Xeon series in the same period are much more expensive than the home-level I3 I5 I7, which is very cost-effective.

Understanding servers is actually to learn about redundant memory, redundant hard disks, redundant CPUs, redundant power supplies, and BMC remote management.

It can be said that the household machine is a high startup, but the base is thin and the ultimate performance is low. The server is a well-established and well-formed server, with at least two of them working together. It has a stable background and good prospects. It is nothing if you want to spend money on servers that require big computing power.

In fact, all server crashes on the 771 platform. As we all know, a large number of servers on the 771 platform have been in service for five years, and many companies have begun to retire them. The high-end 771cpu can reach the 4-core GB clock speed. In terms of lithography, most of the 771 platforms are 45nm, and the latest lithography is 22nm. It seems that there is a big gap, right?

The problem is that intel's cpu consumption has been reduced in the past two years, and its performance has not improved significantly. This is related to the architecture and the computing power provided at the same frequency is basically equivalent. The gap is power consumption.

4-core, 2.5 GB, second-level cache, 45nm, 12 m, what is the cost? The i5 configuration is sold for 155, isn't it expensive?

Not powerful yet? There are also dozens of 3G clock speed instances waiting for you. In fact, the computing performance of this u is similar to that of the early generation i3. Although the configuration is equivalent to the current I5, the performance should be ignored. The skinny camels are bigger than horses, so they can be equipped with two servers without being able to withstand them.

If you have a cpu, you have to have a server chassis and a motherboard.

We recommend that you start at least from Dell 1950. This server supports a cpu of 54xx, which is basically 800.

If you buy a cheap model, such as a cpu that only supports 51 and 52, you may only need 700.

If you don't like Dell, you can choose hp. This price is suitable for using dl360g5. If your hp machine is better, you can search for code to crack ilo on the Internet and learn to use bmc for remote management. Below the machine is less than 1000, cheaper than Dell. [Note]

The server memory is very cheap, basically like 2 GB memory for 40 yuan, so don't worry about expensive memory.

We recommend that you buy a new hard disk. Although the server can be used, the new hard disk is often more efficient than the old sas. In particular, Seagate's 1 TB disk is much faster than Western Digital. Buy two groups of raid and learn everything.

Of course, there is also a benefit for machines that buy hp. hp machines have 4 2.5-inch hard drive slots. You can learn to configure raidd10.

Now we have about 1000 pieces of servers that can be used for learning. If you want to calculate a little bit for the middleware, you can buy a Dell r410 series of machines, about 2000 pieces. If you want to learn how to configure the cluster, so two 1000 machines can also be built up. 1000 machines with a single 16 GB server cannot be expensive in any case?
