Trick to connecting server directly to SAN? by
Rob Lancia
I have what may turn out to be a very basic question about connecting
a Dell server to a DataDirect Networks SAN. I should mention that all
of the existing setup was done by someone else, and although I have
the DataDirect User's Guide I have no real SAN experience to fall back
on.
The gist is...

Guide to the common implementations of RAID by
Dave
Hi guys,
I've written a short guide to the most common levels of RAID in use,
mainly so people new to computers and storage solutions can get to
grips with it. I know I would have found a guide useful a year ago when
I was new to RAID. I know there are many resources out there, but I
tried to make...

Why Can't NetApp Keep Time by
[email protected]
The company I work for has NetApp file servers and according to our IT
people, they can't keep proper time using NTP.
Why not?
Consequently, builds across network drives are a nuisance. Apparently
the clock drifts fast and our ops set the time slow to compensate. We
don't have to have the...

Dan Langille
Hi folks,
I have a QUANTUM DLT7000 1624. It's mounted internally. The base of the

Is this normal/expected/unusual?

Question on Tape file system (NTBackup) by
arizvi
Hi,
Is there some information on what the file system created by NTBackup
looks like. I am new to storage technologies but I am familiar with FAT
and NTFS file systems. If you can point me to the right source or
explain the overall architecture, I'd be grateful.
Thanks,

Cache Battery - What if power goes down more than several days? by

Hi:
A very happy EMC Clariion CX customer says that he will not consider
buying an IBM FAStT because in case of power failures, the CX
automatically downloads unwritten data from cache to disks using their
self power cells. Does anybody know about workarounds to have this
kind of safety with IBM...

Disabling disk cache? by
Nuno Magalhaes
Is it possible to disable hardware disk cache? Not the software cache.
I can read files with no software cache, opening them without
buffering (FILE_FLAG_NO_BUFFERING) but I can't avoid the hardware
cache.
Is it possible to get the hardware disk cache size? Or even disable
it?
Thanks a lot.

TSM storage used? by
Mike
How can I query TSM to find how much storage is currently in use
now (tape) for all the files (corporate-wide) that are backed
up (under TSM's control)? I was just asked a question do we
want to get rid of the tape robot and move to JBOD instead.
Thoughts on doing that kind of move?
