Question about memory

["Prowell, Stacy J." <prowellsj%ornl.gov@localhost>]

I have a question about memory, and hope this is the place to ask.

I have blades that have 1.5TB of DRAM, and want to run NetBSD if I can, but I am hitting the 512GB limit.  “panic: RAM limit reached: > 512GB not supported” 

Can someone give me a sense of how much pain would be involved in raising the limit… or let me know to give up and move to another OS?  I can tell you the next round of blades will probably have >2TB of DRAM.

Thanks in advance for any help,
Stacy
