Thanks for explanation, Neil,
I have also looked to document "Compare Informix Dynamic editions" by
C. Normile and related IBM's document ENUS206-063. It seems to me that
for our purpose Express should suffice. I would say that for Dual-Core
Xeons or Opterons 1 CPU license is needed.
Current server used for the similar purpose has 1 GB RAM and 1.1 GHz
Pentium III. It's not in memory shortage, and usually not CPU bound. So
I expect that 4 GB RAM and Dual-Core Xeon or Opteron should suffice for
few/several years. I could add second CPU later, if a need arise. The
amount of data is large but the concurrency of usage is low, and
usually the load is low also.
In my country (and even region), it is not easy to speak to someone
with good understanding of licensing terms related to Informix. IBM's
interface to us is mostly sales force, and partners are also focused to
amount of sales. And yes, they push DB2 and WebSphere related stuff
heavily. Users of Informix are next to extinct, usually being in some
phase of transitioning to some other DBMS. Usually the most valuable
information I collect from Web, mostly from this newsgroup and IIUG.
After reading the specs, I like DL380 G5 (with Xeons) more than DL385
G5 (with Opterons), since there are some nice things like Gigabit
Ethernet NICs with TCP/IP offload capabilities and more modern design.
But those Dual-Core Xeons (51XX series) are rather fresh CPUs, and I
know noone with experience of using them with IDS. I have heard of good
experiences with Opterons. Any comment?
