x86-64 architecture presently allows 256 TB (48-bits) physical addressing, and Itanium and at least some its operating systems (HP-UX, OpenVMS) have 50-bit physical addressing available.
The big HP NUMA boxes are Superdome and Superdome 2, and those have global memory access, though access to the local memory is faster than the remote memory; the requisite non-uniform memory access speeds.
Last I checked, the current Superdome and Superdome 2 series maxed out around two and four terabytes of physical memory.
If the current four terabyte maximum memory configurations and possibly the architectural 50-bit addressing aren't enough and you're willing and able to buy that much physical memory, then HP would probably interested in chatting with you.
No RHEL on Itanium, though.
- Nrsolis 15y agoFor some reason, I thought that Intel had abandoned the Itanium platform. I was surprised to see that HP was still marketing machines based on that processor line.
- tsotha 15y agoYou might be thinking of Microsoft, which dropped support for Itanium in 2010.
