Steve ..

First .. this statement -- "use the i5 CPW for real work." -- is nonsense.
Telephony is by far the most important service that IS provides, and has by
far the most demanding uptime requirements.  If email is down for a day, I
get yelled at.  If the telephones are down for a day I get fired.

how many sites run email on the system i?

Second .. a huge driver toward putting telephony on the System i is
reliability; it is far easier to get the necessary reliability from a System
i than from Intel-based hardware.

Third .. you ignore the value of consolidating functionality onto fewer
physical servers.  It is harder to manage 10 services on 10 servers than it
is to manage 10 services on 3 servers.

Fourth .. on a mid-sized System i, the incremental cost of the 700 CPW is
relatively small.  Disk requirements of a phone system (even with voice
mail) are trivial.  Many companies will be able to fold this onto their
existing System i.  Those that can't (or choose to use separate hardware)
aill likely find that the System i hardware costs for the small system are
not out of line.

your right Tom. Too bad IBM pricing of the i5 prevents us from getting
to the point where we can run everything on one server tower.  Here is
a double quad core p5 priced at $23K
http://www-03.ibm.com/systems/p/hardware/entry/550q/91331eaa.html

That system would provide something like 20,000 CPW. Plenty for
running mail, telephony, web, green screen in a mix of i5/OS, AIX and
Linux partitions.
