RE: Model 600, part of history?

[Neil Palmer <npalmer@xxxxxxxxxxx>]

Leo,

With the 170's there are few reasons these days to consider a 600 or
S10.
A few differences between a 600 or S10 and a 170:

MAIN STORAGE
512MB max on the 600/S10.  1024MB on the 170.

DISK CAPACITY
With V4R2 600/S10 can take the 17.54GB disks, for total of 175.4GB (vs.
85.8 on 170 which can't use 17.54GB units).

TAPE
Only reason here would be if you wanted an internal 8mm tape.  600/S10
can, 170 can't
On the other side of the argument, the 170 (expansion unit/sidecar
required) can attach 2 external tapes (1/2" Reel or Cart, 8mm), 600/S10
only 1.

TWINAX ADDRESSES
600 unit can have 188 vs. 68 on base 170 (BUT the 170 "sidecar" can add
another 160 for 228 address total).
Only 28 twinax addresses on the S10 server.

COMMUNICATION / LANS
9 comm lines on a 600/S10, 12 on a 170.
3 LAN ports on a 600/S10, 6 on a 170.
1 ATM adapter on a 600/S10, 3 on a 170.
1 IPCS on a 600/S10, 2 on a 170.


As for going to a 2159 today and upgrading to a 2164 next year.
Advantages are:
2159 is in IBM's P05 Software Group, vs. P10 for a 2164, so you wouldn't
need to pay the extra for IBM software for a year.
Also, you would save the cost of the extra charge for the 2164 processor
for a year until you needed to upgrade (and you may find the 2159 is
giving the performance you need and could defer this upgrade a little
longer).
And the higher the processor model, the higher the maintenance charge.


What model 600 are they looking at in comparison to the 2159/2164
scenario, a 2129 ?
If that's the case, and they mainly need interactive performance, the
600 could be a better priced solution as you could stay with the 2129
which is at the P05 Software Group.  If you were looking at a 2134 or
2135 you would be back at the P10 group, like the 170-2164.  (You could
step up one processor level on the 170, to the 2160, and stay at the P05
group).
However, if interactive performance wasn't quite so critical, and you
could take advantage of the faster batch/client server performance in a
170, the 170 may be the better deal.

Performance comparisons (CPW for V4, interactive/batch - followed by IBM
Software Group):

600-2129        22.7/x          P05
600-2134        32.5/x          P10
600-2135        45.4/x          P10
600-2136        73.1/x          P20

170-2159        16/73           P05
170-2160        23/114          P05
170-2164        29/125 *        P10
170-2176        40/125 *        P10
170-2183        67/125 *        P20

* Client Server/Batch performance constrained by memory/DASD maximums.
If your application has heavy CPU bound tasks, you may be able to take
more advantage of the unconstrained ratings of the 2164/2176/2183 which
are 210/319/319 respectively.
