Subject: RE: iSeries specific benefit - Disk IO performance

What intrigued me was the caching mechanisms the i5 has
including everything down to having a dedicated battery to
retain records that haven't yet been written to disk in the
event of a power failure (do a search for NVS in above
article for reference).

It would be my guess that a Wintel box DOES NOT have this
intimate disk IO and performance tunage. Would that be a
true statement, or is it a "depends on where you buy your
hardware" type deal?

Depends on where you buy your hardware. All of our HP servers have the
same
feature.

I would love to start an online list of feature comparisons
where the i5, in its entirety, is compared to other platforms
(most specifically Wintel/.NET implementations), and this
would be one such entry that most might not think of
initially but in the end can be considered a plus that the i5
has over other architectures/platforms/implementations.
Often times comparisons are done at the application tier
(i.e. RPG vs. .NET/Java) and the whole picture isn't taken
into consideration.

OS/400:
- work Management
- single level store
- TIMI
- comprehensive auditing & error reporting

Those are the main benefits.
