Geert,
Also played 'what if" with the HSA Estimator tool, determined 2GB would be
the magic number for us (includes some added room for Dynamic updates). Ours
is a z9 EC 2 book, OSA channels are spanned, hipersockets are spanned, ICP
are a mix of spanned and shared, 13 LPARs, 2 LCSS, all escon, no ficon.
YMMV.
Regards, Doug

Subject: HSA size on Z9 BC
Hi,
We have been talking to Santa recently and *maybe* this time he will bring
us a z9.
But I've been told that the HSA on a z9 can be quite large, compared to the
current 128 MB on the z800. So I've been playing with the "HSA Estimator
tool for z9 BC v2.9.1" on Resource Link. The minimum HSA-size the tool
predicts (specifiyng 0 devices, no dynamics, no hypersockets) is no less
than 1216 MB. Using more realistic numbers for devices etc., I get a HSA
size of 1536MB (1,5 GB!). Which is *huge*, compared to the z800.
Are these sizes realistic? Can anyone using a z9 give me an indication of
the HSA-size on their machines?
Thanks!
Geert.
