Thanks all for your responses. Luckely I've been a bit conservative when it came to allocating the 8GB on our current CPU (we went from 1GB on a 9672 to 8GB on a z800). Otherwise we may have been in trouble, with "only" 6 or 7 GB os-storage on a z9. Still, for IBM it may be a small step, but for me it's quite a leap seeing the HSA growing ten-fold. What goes in there nowadays? Hopefully the VM and VSE folks at IBM don't go down that same road... Bye, Geert. _____________________________ Geert Dieltiens Systeembeheerder Informatica J.

I was surprised at the amount of storage the new HSA used. We didn't use the estimator. We did loose at least a gig of storage. Luckily we weren't memory constrained. The first time I ran into this situation, (many years ago) was at another shop and they were running a 4381-92E. We had always run VSE native and didn't need any of the special features. When we went to VM on this box, we had to install an IOCP. We were already memory constrained with 64meg and it seemed the IOCP we coded req'd 16 meg. So that cut us to 48meg. Our IBM rep had failed to tell us about this memory hit. Getting the IOCP loaded the first time is a whole other story. I've never understood why IBM used customer storage to load the IOCP/HSA. But, then, as many people have mentioned, IBM is in the business to sell hardware (memory). Steve G.

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. _____________________________ Geert Dieltiens Systeembeheerder Informatica J.
