Server VS Standard PC – What Is The Difference? (Part II)

Disk Subsystem:
Server motherboards have an integrated RAID-controllers that allow you to “merge” several physical disks into a single volume, thus increasing productivity (increasing the speed of reading and writing), as well as fault tolerance (recorded data is automatically duplicated on other drives that can store data in the case of death of one of them).
Servers make it possible to “hot swap” – the replacement of hard disks on the fly, without shutting down and stop working, which is very important in case of emergency situations – for three minutes, and users did not notice anything, continued to work quietly.
Motherboards conventional PCs middle and upper price ranges and will have a built-in RAID-controllers, but in most cases, these controllers are less functional, and allow you to configure only two hard drives in most cases, much less than four. Of course, you can install extra RAID-controller, while again increasing the load on the power supply and creates additional obstacles for air circulation.
Conventional system blocks do not permit “hot swapping”, hence the death of one disk in the RAID-array, of course, will not lead to data loss, but will shut down the server (and all its users) for a long time – to set the new drive and re-creation of RAID- array.
Hosting:
Building dedicated servers, in most cases is a large body of conventional PCs, which primarily prevents normal move air to cool, and secondly, to install more hard drives. Also worth noting steel, which is made from body – its thickness ranges from 1 millimeter or more, that, firstly, greatly reduces the noise level coming from the server, and secondly, to avoid damage to the hand during assembly and maintenance of servers in Third, increases the mechanical strength and reliability.
Consider building a conventional computer : A small amount of air circulation and difficulties, the inability to install a large number of hard drives, thin and sharp steel cabinet that one side can be easily damaged, and on the other hand it is easy to get hurt. Increased noise.
