Home -> Community -> Mailing Lists -> Oracle-L -> RE: Hardware Question
The answer is: A significant amount of money.
We will get a return on our money in a fairly short amount of time. Support costs on the old hardware are pretty high.
A new SAN is in the works as well. The frustrating part is that the DBAs suspected this bottleneck for a long time but it couldn't be proven. Apparently, some of the monitoring tools that the sysadmins use never picked it up. There is a tool that is specific to the controllers that finally showed it them (only recently). In the sysadmins defense - they were a bit annoyed to at the fact that nothing else showed the problem.

Subject: Re: Hardware Question
Hey Jay,
I hate when management comes to me with questions like you mention about
this new hardware handling the workload.
But, I have a response now that I love because it can be confusing to
them.
I simply ask, "Why?".
Why are they looking at new hardware? Does the current hardware not
handle the workload? Is there a forthcoming app server/database upgrade
that will require more resources? Are they scaling out their current
utilization, perhaps to more users? Are they adding more databases? I
know this may not seem like the best attitude and trust me, I love
newer, faster hardware more than most, but really the justification for
new hardware should come before the shopping for hardware. In my role
as a DBA, I should be the one (or, of course, the sys admins) that
recognizes the need for hardware upgrades and hopefully before
management starts to feel the need. If I can't quantify the need for
new servers or additional hardware (or software for that matter), I
actually speak against it. This way, when I tell them we need
something, they listen!
Just one guy's 2 cents.
However, you mention a bottleneck on the SAN controllers. That is a big
red flag. There's always a chance (and some would argue a very good
chance) that faster processors and more memory will make this SAN
controller bottleneck worse or at least more noticeable. Hopefully,
additional channels to the SAN are being considered with this new box as
well.
Good luck!
