2U indicates a case that occupies two spaces in a rack.
The 2U and 4U are about the same size -- 2U occupies two complete adjacent rows, while the 4U occupies four rows at half-width.
A typical 2U rack is approximately 3.5 inches in height. A standard DVD is 0.047 inches. With that being said, you could fit approximately 74 standard sized dvds without the case in a 2U rack. On the other hand, a standard DVD case is approximately half an inch thick. This would mean in a typical 2U rack, you could fit 7 dvds in the case.
Rack mount server dimensions are specified by a 'U' value. The larger the 'U' value, the larger the size of the rack mount server. The 'U' only only specifies the standard width and length, with the depth being a variable. So, the '2U' has a standard dimenson of 19"x3.5". The common depths for the '2U' are 17.7, 20.9, or 24". The 2u stands for 2 units, as in it's 2 units tall. Rack mount servers come in varieties from 1 unit tall to 4 units tall.
rack space refers to how many slots the server ocupies in a rack, eg 1U 2U--the U representing 1 slot.
what is the difference between a server physical case and a client case
2u + 1 = 5u + 5 2u - 5u = 5 - 1 -3u = 4 3u = -4 u = -4/3
Do you mean: u² + 2u + 1 - v²? If so then= (u + 1)2 - v2= [(u + 1) + v][(u + 1) - v]= (u + 1 + v)(u + 1 - v)
instead of searching in case of universal server we can use the server in case of a.s.p which the acess time is less
Sure you can... whether or not its illegal is a different story though.
What is (the name?) (of) a secondary server (who) takes over in case of primary server failure? That would be a BDC. A Backup Domain Controller.
Here are some different 2U rack mounts you can buy: http://www.rackmountmart.com/html/2UTable.htm .
What do you mean by find a server. Like a private server?
