[Info-vax] Integrity i2, i4, i6 relative performance (was: Re: Large Qty of rx2800 i2 i4 & i6 in STOCK)

[Forster, Michael]

Thank you!

Also many of us need to consider something you all are well aware of - what's supported or certified by our database and application vendors. Big problem currently that prevents many financial or healthcare organizations from migrating to VSI versions and i4 or i6 platforms.

Some performance-related and feature-related reading:

Integrity i2 Tukwila to Integrity i4 Poulson can be a nice performance jump.

There are some performance-related feature upgrades in i4 and i6 over
i2, too.  Alignment fault handling improvements, and some out-of-order
support, etc.

Integrity i4 Poulson and Integrity i6 Kittson seem to differ only in
binning and in labeling.

A few select i6 processor bins are slightly faster than the fastest of
i4.  IIRC, around ~15%.

Outside what arrives with the slightly faster clock on a few bins, i4
and i6 performance differences are negligible.

If you're on i2, consider i4 or i6.  If you're already on i4 and not
right on the edge, then i6 as your i4 ages out, and/or if you need the
longest hardware-support window.

For i4, might want to look at more memory, or SSDs, or faster HBAs,
etc., before i6.

YMMV, etc.
