Bit late throwing in here, but you can but an IBM DS3700 in 4U in a standard rack. ?60 drives in 5 drawers of 12.

It's also marketed by Dell and NetApp (I believe NetApp actually build it but not sure).

Stephen,
There are several ways to do this, but the drawer style drive bays have been known to have issues as far as showing up on a controller storage manager. Some of those chassis were even discontinued because of drives failing to show up. ?I feel much more comfortable with using 3.5" drives that are front and back inserted. ?It may not be as dense as can be, but it is the best balance of density and reliability you can get.
You can cheaply and safely manage petabytes of storage using several RAID controller cards, each linked up to a server with multiple PCI-Express slots. ?
There are two ways to do this:
With higher performance
You can have a server with 24 bays, linked to a controller card for high performance. ?We have seen with our 10GbBaseT about 950MB/s performance, and you can team those ports as well for even faster performance.
That same server can host other controller cards with external ports, and you can use 45-bay JBOD chassis. ?That would give 180TB of reasonably good performance. ?Each controller can daisy chain 5 180TB JBODs. ?That's 900TB per controller.
With high capacity
Get a 2U server with multiple PCI-Express slots, add controllers, then add JBODs. ?These JBODs are also daisy chainable.
That same server can host other controller cards with external ports, and you can use 45-bay JBOD chassis. ?That would give 180TB of reasonably good performance. ?Each controller can daisy chain 5 180TB JBODs. ?That's 900TB per controller. ?
Both of these options are reliable and much cheaper than with other solutions. ?You can get an 180TB JBOD/SAS for around $30K, and a high performance 96TB SAS server for under $30K as well, depending on options.
I have several customers doing this and they are very happy with the outcome.
-Donn.

Subject:?Re: [SSA-Discuss] Your preferred Linux Desktop Environment
?Did you try turning off compositing in the compositing window managers? You lose your bells and whistles but I have a feeling that as soon as you ask your window manager to take bitmaps of your various windows so it can make them transparent or have glowy borders you're gonna lose performance. Shane.
No - although (quickly googling to become an instant expert in this area) since Mutter (doesn't work smoothly) is supposed to be Metacity (window manager and does work smoothly) plus Clutter (compositing) it seems reasonable to assume that Clutter/compositing is the problem. Obviously many uses of window managers don't really care about accurate frame rates, but some do. Googling shows a 2010 patch to remove the ability to turn off compositing in Mutter on the grounds that if you wanted that you would run Metacity.
cheers,
Don Craig

Subject:?Re: [SSA-Discuss] Deploying your Adobe Cloud Team Installs
A good starting point would be a 'recommended practices' type of
document that sysadmins could somewhat agree on, and then float that
to the vendors.
I have such a document myself on recommended practices for
command line tools. It's surprisingly long, but goes into
details I've seen software vendors go wrong on:
http://seriss.com/people/erco/tmp/good-command-line-renderer-practices.txt
TLDR, hitting items like:
? ? ? ? o Executable's filenames should not contain spaces (!)
? ? ? ? o Return proper exit codes; 0=success, >0=fail
? ? ? ? o When you can't open a file, print the pathname /and/ OS error (not just "can't open file")
? ? ? ? o Avoid negative exit codes
? ? ? ? o ..etc..
I could see sysadmins doing something similar.. things like:
? ? ? ? o Scriptable software installation
? ? ? ? o Instructions for installing on a network drive
? ? ? ? o How user preferences should work and where they should be saved (win/mac/linux)
? ? ? ? o etc..
Then see if you can get general agreement from a bunch of admins,
and use voting to resolve disagreements. google docs is a good way
to manage such a document; this way many folks can edit at once,
and one person can 'manage' the document.

Slashdot sayeth:

So, not 19" (ok) and not 23"WE/580mm ETSI (uh .. ok). ?It's something
else entirely. ?How "Open" is that? :)
