When I go shopping for network infrastructure, I see lots of different kinds of racks available and I don't understand the difference between them. What are the different types of racks you would typically see in a datacentre?

Can this question be any more ambiguous? – Greg Feb 9 '11 at 11:56

I dont know if it's what you mean, but in my knowledge, there are 6 main types of racks or cabinets for switches and servers:

  1. SOHO LINE CABINETS: 7U, 9U or 12U; could be wall-mounted
  2. SLIM LINE CABINETS: 5U; wall-mounted
  3. MINI PRO LINE CABINET: 7U; could be wall-mounted; with 2 side pannels for cabling
  4. TRIM LINE CABINET: 12U; wall-mounted; for low-profile accessories
  5. SERVER LINE RACKS: 26U, 36U or 42U for servers and other accessories that require depth.
  6. UNIVERSAL LINE RACKS: 26U, 36U or 42U for network equipment.

I hope it's what you were looking for.

Number 5 and 6, in 42U height, are the one you will find the most in DataCenters. – waszkiewicz Feb 9 '11 at 12:31
And each of those is available in various depths and almost unlimited designs and configurations. – John Gardeniers Feb 11 '11 at 0:41

Racks differ in their height, given in Rack Units, but also in their widths and depths. These dimensions become very important when you start cabling your components and/or adding switches and/or PDUs on the rear of your racks.

Always check your needed widths and depths also.

Good point, that's true! – waszkiewicz Feb 9 '11 at 12:48
