Certain companies (LSI, DDN) have enclosures that hold 60 hard drives in 4U of space. Why is it that these kinds enclosures aren't available unless you get them as a part of a "solution"? A 24 bay enclosure will run let's say four grand, why hasn't any manufacturer stepped up to provide that kind of chassis? Is there no demand, is the problem with heat management or do they actually exist and I'm just oblivious?

What do you mean by a "solution?" A server in addition to the disks? –  Mark Wagner Oct 8 '10 at 23:31
    
I have been thinking about this, you could theoretically fit 60 2.5inch Disks in 4u, but there is no way that you can fit 60 3.5inch disks in 4u. they wont physically fit. –  Geraint Jones Oct 9 '10 at 1:52
    
There are enclosures by several companies that fit 60 3.5" drives. The enclosure slides out like a shelf and the drives go in vertically. –  Novikov Oct 9 '10 at 6:18

I've recently found out about a product from SuperMicro that I don't believe is available yet... 72 2.5" drive bays in a barebones unit.

SC417E series - Extremely High-Density 4U Storage Server Chassis

details on http://www.supermicro.com/products/nfo/2_5HDD.cfm

Third server from the bottom.

http://www.supermicro.com/products/chassis/4U/?chs=847 - 36 drives in 4U

Last one we purchased was $880 or so from our supplier.

http://www.supermicro.com/products/chassis/4U/847/SC847E16-RJBOD1.cfm - 45 drives in 4U, no room for motherboard, must be chained off another chassis. Listed at roughly $1500 at our supplier.

Not quite the density you're looking for, but, there are a number of companies that do it. If you can do 2.5", the solution listed above will probably have a very high build quality. We've used Supermicro almost exclusively since 1998.

That one is outdated. New one is 72 (!) discs in 4u (2.5"). Wonderfull monster ;) –  TomTom Oct 9 '10 at 3:15
    
On top - the page lists heatsinks and mobo compatibility info - so that part is also wrong ;) –  TomTom Oct 9 '10 at 4:46

Same as Nexsan SATABeast (48 disks, with either 1 or 2 controllers) –  pauska Oct 9 '10 at 1:48
    
Kinda, the Nexsan looks to have an embedded OS/Firmware; the thumper is a full Solaris server ;-) –  Geraint Jones Oct 9 '10 at 1:50
