Question

What needs to be done to a server rack to get servers in them?

Answer 1

First let us know what a server rack is used for.

Server Rack: A server rack is two way open cabinet that is used to put servers, ethernet cables, power supply etc to utilize the space, keep your devices cool and optimize them.

All the servers that are used in the rack are designed to be installed in a framework and called rack servers.

The capacity of a rack is counted in "Unit". The space required for one server is counted as "1U" and for 2 servers as "2U" and so on.

A general server rack can hold upto 42 servers counting upto "42U".

Channels: A server rack consists of channels helping the devices placed on them to be accessed with ease without disturbing the other devices as they slide outside.

Now let us know what servers are and how they can be put into a server rack.

Server: There are two types of servers.

1) Rack servers 2) Blade servers

1) Rack servers: Rack servers are installed in a central framework which are especially used for providing remote access to a private network.

2) Blade servers: They are compressed, high dense servers having their own CPU and memory used for more efficient processing, occupying less space on the rack and having their own cabling. But all of this comes for a price which does not make the suitable for all business requirements.

Installing servers in a server rack

• Knowing the business that is being setup is a major criteria as it decides the rack size, number of servers and the firewall that is required.
• A server rack is connected to the internet through an ethernet connection. It should be connected to more than one network proiders, if one network is down the other network keeps it running.
• There are two types of connections. 1) LAN 2) WAN
• LAN : They provide inter-connectivity between the servers inside the rack.
• WAN : They provide connectivity between the server rack and the ISP (Inetrnet Service Provider)
• Routers: Routers take information from the broadband signal via modems decodes it then finally delivers it to the server rack, further distributing the received broadband to the servers in the server rack.
• Firewall: A firewall is devicce that exists between the inetrnet and the rack. It protects the servers from all the dangerous intruders on the outside.
• Cooling System: When so many servers are running it is natural a lot of heat is produced. So for all the servers to work find it is better to install a cooling system.

Now the server rack is completely ready to be used with any operating system like (windows/Unix/Linux).
