Re: 57##SS1 option 42 Journal caching

Ok now I'm following....

Well...like Dennis says IANAL but...

It would seem to me that the mistake made was in not setting up
journalling during your testing of SSDs at the IBM lab. The question
is whose responsible? Honestly, I'd split the blame between whomever
is responsible for your system performance and IBM. Assuming you
don't contract out performance monitoring, then IMHO whoever handles
it in your company should have realized that journalling without
commitment control is a dog. :)

At the same time, the guys in the IBM lab should have certainly been
aware of it and shouldn't have let you test the SSDs without
journalling turned on.

If you paid some sort of fee for consulting services when you where
doing your SSD testing, then I'd think you've got a pretty good
argument for either returning the SSDs and buying the journal caching
option or getting the journal caching option gratis.

Good luck!

We threw tons of money at the wrong problem and purchased SSD's to speed
up our month end.  Turns out the real enhancement is supposed to come with
journal caching.  I have coworkers who believe that it should just be part
of the OS and you shouldn't have to pay extra for it.

Rob,

I don't understand your question...

Please read this article about journal caching:

Then I've got to ask you, what is the line, if any, between some people
ponying up the money to get IBM to develop journal caching and those who
consider having to pay for this about as popular as the 5250 tax?
