I had a typo in the first post. The Record Reads per day should be
50,000,000, not 500 Million. My mistake. One decimal place makes a huge
difference. Our current app is Progress based with running on an IBM p650
with 4 processors and suspect a similar load if we were to changes apps and
databases.
Thanks,
Jeff

Well, that are big numbers. What do you need is for sure
big iron.
Tell us what are you planning to buy in order to support that load.
My actual experience is ( rougly ):
100 concurrent users
2.000.000 read for 12 h
1.000.000 update for 12 h
50.000 new records each day
as you can see this scenario is far aways from your need
but we are using only a two processor Intel Xeon 2.8 GHz in
hyperthreding mode with a not so tuned RAID system and only
1 GB of RAM.
I think that with 8 processors, good fiber channel access to your
RAID, and good ammount of memory you can easily reach that numbers.
This is a challenging task to accomplish, do you need any help out there ;-)
