Two tiny questions:

>>a) Do the users need instant access to the files or is long-term archiving an 
>>option?

Unfortunately, the app that creates the files distributes them across the LUNS, 
and they are indexed in a giant SQL data base.  The files can't be removed from 
their original location.

>>b) Not sure if it would help the issue with long respons times when browsing, 
>>but HSM might be an option?

HSM leaves a stub file, so there would be even MORE files on each LUN!  Our 
problem isn't the size of the LUNS, it's the number of files in the Windows 
directory.

>>Your biggest problem isnt now, it's when u need to restore those 70 million 
>>files. 

I agree completely!

Ärende: Windows servers with a kazillion files and Win2K8...

I have a site with an application that generates kazillions of tiny files that 
are stored forever.
I've already yelled about it, but it's a purchased, customer-facing black-box 
app that they really can't change.
(Naturally, when it was bought umpty years ago, nobody thought about the 
problem reaching this size or what the ramifications would be.)  Every day the 
app creates more files.

They have multiple Win2K3 servers that already have multiple luns containing 
over 35M files each, one is over 75M files.

We are using journaling to back them up successfully (most days).
But it's a struggle just to expand the file tree with Windows explorer, and 
there are exposures on the days when the journal gets overrun (takes 72 hours 
for TSM to scan the filesystem and revalidate the journal).

Looking for anything that might help save our bacon.

Has anybody had experience with this issue and Win2K8?
Does Win2K8 do any better than Win2K3 at handling huge numbers of files in 1 
NTFS directory?
Upgrading the OS is something application-independent we might be able to do.

Thanks for any insight!
