Greetings,
I caught up with Peter this afternoon.
He has one of the three quotes back. Part of what was behind his questions
was the total price of the quote he has received. Basically it boils down
to do we REALLY need the scaleable server, or would the model 170, which is
a slower, single processor box, really do what we require, for say the next
twelve months. Will we realistically be adding, or at least start adding
the non central printers before the end of the year or will that actually
not start until 12 months out?
The 170 would still have the RAID. The rfq he sent out has six spindles
but only 18 gig of usable for "data" or non operating system stuff.
Part of the concern Peter was expressing is that the response he got was "a
lot" of money, and if he does the expensive stuff for the print server,
what does he have to say no to on other servers to make his budget work for
the year.
I expressed that I would send this email to the group and let the team hash
out the question rather than just me trying to make the decision whether to
stick with the scaleable box or go with the 170, single processor box.
I did run some numbers around the general ledger print file sizes. What I
came up with by, adding up the number of records in the 21 print files,
then multiplying by 132, (assumption of 132 byte records), came out to
about 834 meg of data. When I cross check this number with the size of the
spool space, 2000 cylinders times JAD's magic number the spool space is
about 1.32 gig, which allows the general ledger to hit the spool space and
still have some room for "normal" print files. So if we round up to a gig
for the general ledger, and for a rough guesstimate quadruple that for
postscript, we only need 4 gig for the general ledger to hit the queue and
then be retained. So the 18 gig of disk is sounding reasonable at this point.
