What about my questions ? Thanks.

"Nobody in their right mind would use OpenBSD for that." That's how literally all of the projects I've used OpenBSD for have started.

None of this is the domain of OpenBSD and nobody in his right mind wants to run Stackexchange on OpenBSD. Or are you suggesting that SAP should port HANA to OpenBSD? Best Martin
Re: Dell R930 server
I would say big data. Stackexchange have a pair of SQL Server, with 384Go of memory for stackoverflow and 768 for everything else, a Redis server with 256, a server for elasticsearch with 192 and same quantity for an HAProxy server. And that's just a successful website. They aren't a search engine or a social network 2016-11-08 23:38 GMT+01:00 Mihai Popescu : > | Does OBSD "see" all the 96*128G memory available ? > > Out of curiosity, what does need such a memory today?

| Does OBSD "see" all the 96*128G memory available ? Out of curiosity, what does need such a memory today? Do you want to use a ramdisk? Thanks.

Simply doubling the space supported to 1TB would be an easy first step and -- given someone with a machine to test it -- should work out any kinks in the use of the direct map. 40 physical bits in the professed default for long mode, so it's really what the default should be. Doing the second step to full dynamic would then be about getting the ASM right when values are not longer constant. Philip Guenther

We only allocate a single PML4 slot for the direct map on amd64, so it's currently limited to seeing 2^39 == 512GB.

Does anybody here run openbsd on this machine ? Does OBSD "see" all the 96*128G memory available ? Thanks in advance.
