Sk149973 describes the switching from kernel mode to user mode. Does this mean that I can use more than 40 cores in user mode for CoreXL?
- If so, this would also work with open sever?
- If yes, what is the maximum number of possible cores?
CUT>>>
There are a limited number of cores on 23900 appliances due to Linux/Intel limitations.
In kernel-mode FW, the maximum number of running cores is limited to 40 because of the Linux/Intel limitation of 2GB kernel memory, and because CoreXL architecture needs to load a large driver (~40MB) dozens of times (according to the CPU number, and up to 40 times). Newer platforms that contain more than 40 cores (e.g., 23900) are not fully utilized.

Enable user mode:
> cpprod_util FwSetUsermode 1
> reboot

How to enable USFW (User-Mode Firewall) on a 23900 appliance
Not aware of any supported Open Server that has more than 40 cores, but I imagine it would work there as well.
No one mentioned a number of core limit with usermode firewall.
Thanks for this info.
Theoretically, we could have 56 cores in an HPDL380 G10.
2 x Intel® Xeon® Platinum 8180 Processor (28 cores per cpu)
But I didn't have this server in my hand yet:-)
