Solutions for diskless Internet cafes with 60 machines in small-sized Internet cafes

This is my first small-sized internet cafe with no disk set up solution. My debut is not well written. I hope you will give me some advice.
Because small Internet cafes have financial concerns, the investment in equipment is relatively low, but it can ensure the stable operation of Internet cafes.
The following is a detailed description of the topology I have drawn.
        
 
Start from network access
1. Router selection: If your bandwidth is surplus, the routing standards can be reduced a little. If your bandwidth is insufficient, you have
Force up and down. If you want to choose a specific route, you can also contact me for advice. I can provide you with a good soft route solution.
2: choice of The Master Switch: In this example, the solution is based on the solution of 60 machines, so the choice of the master switch should not be made much effort to ensure
GE switches, non-managed, are fine. Small Internet cafes use few aggregation functions. In addition, most diskless ECSS now support Nic shunting.
There is no need to aggregate machines.
3: Switch-by-switch option: Switch-by-switch uses 24 ports of all thousands of switches. Try not to use all ports of each switch to prevent the switch from being used.
Some machines in the region cannot be used when a port is broken in the process. Therefore, it is necessary to reserve a certain port, and the switch must be selected.
Good reputation in the market, stable performance, not necessarily pursuing big brands. (Personal opinions do not represent everyone's opinions, because rich people
Multiple)
4: server configuration: I only use my positioning as an example. I belong to the poor series, but also pursue stability. Therefore, the configuration is relatively low but stable.
Qualitative is good.
A. Diskless server configuration: it supports dual-core motherboard, 16 GB memory, and a motherboard with a minimum hard disk interface of 5 coders. It has better performance.
Best. Cpu e5300 memory 4*4gddr3 hard drive 1*500g 4*320g network card board load 8111c and an independent 8169
Hard disk arrangement for diskless servers (I will explain how to create a Ruiqi + Wangwei master virtual disk ): 1*320 minutes 4 zones C drive 20g server system D drive 20g without disk software and some necessary software, E drive 40g with client image and create a client D disk image, F disk for system backup and storage of some software such as 1 * GB enterprise disk: 64 K formatting game virtual disk, because of the adoption of large memory cache technology, therefore, the virtual disk does not adopt an array of 3 * GB as the client's write-back Disk. It is not a group of arrays and uses disk-based write-back. Each disk has 20 machines in memory: the current memory price is not high, so I will insert as much memory as the server can insert. I will take 16 GB as an example to describe how to set 12 GB as the virtual disk cache, GB disk, the hit rate can basically reach 90% or above, and the speed is very good. 1 GB is allocated to the client system Image package.
, Three write-back disks, each with 512 MB of memory, the remaining is left to the system. The memory allocation must be good. Otherwise, when the service memory is used up, the server will be stuck with the Nic allocation: because the performance of the onboard Nic is good, the onboard Nic is allocated to diskless boot, and an independent 8169 is allocated to the game virtual disk.
B. Monitoring, data, game updates, and movie servers: dual-core processors are supported. Only the motherboard with six hard disk interfaces is supported, and the cpu can win the dual-core cpu.
Any 4 GB memory (because the processing data is too large, the memory size is relatively good, and the actual test 2 GB is enough) hard disk: The data is different from each other, 1*320 install software on the server system, storage of some data software systems, etc. 1*320 monitoring video hard disk 1*500 game update hard disk 1*2 T local movie storage disk (this can be based on the actual situation to buy a proper amount of hard disk, you can also add a hard disk) Nic * 2 can use an on-board Nic + an independent Nic to allocate a NIC for intranet data, and the other Nic for internet data.
C: toll collector configuration: just take a dual-core 2 GB memory instance.
The number of servers may be too large for 60 internet cafes. Here I will talk about my arrangement. Because diskless servers and data servers are relatively important, they cannot be placed on the bar, it is basically placed in the data center together with the route, so it is not possible to integrate the cash register into the data server. All devices in the data center do not need a display, and all operations and monitoring are performed remotely on the cash register, the server bar is designed to prevent the cashier from accidentally removing the server's network cable and power cord, as well as some misoperations. Therefore, if you put a dual-core 2 GB memory server on the bar, you can also put the Internet cafe voice masters and movies on the toll collector for the cashier to entertain, but here, we must remember that anti-virus security measures should be done well, otherwise the toll collector will still be bad once it crashes.
Network settings in the above solution, diskless servers can be set on the route, the two NICs are not connected to the internet, just open the remote control port on the line, one Nic of the data server is not connected to the Internet, and the other is the same as that of the Internet. It is responsible for updating games, movies, and remote monitoring.
The specific settings of data traffic control are not described in this article.
