I just want to be 100% sure on something...
With an Opteron (or Itanium for that matter) using let's say the RedHat 9 or
AS 3 betas available for those CPUs, how will MySQL/INNODB function?
Specifically does the ability to allocate a bigger chunk of memory than 2GB
just work "out of the box"? Can I set innodb_buffer_pool_size to 12GB for
instance if I have 16GB in a box?
Now then, along the same lines and not really MySQL oriented but someone
here will likely know. I see lots of Opteron boards with 2 CPUs being
advertised that have 4 DIMM slots "per CPU". Is it one large flat memory
space or do they do SMP in some strange fashion where each CPU has access to
it's own memory? Therefore not giving a flat 16GB memory space if 8 slots
were populated with 2GB DIMMs? I hope not but the way they're being
described it is somewhat confusing.
Even more off-topic, anyone know of a good 1U or 2U Opteron or Itanium
system with >8 DIMM slots? 64-bit is great but unless you can stuff a _lot_
of memory in it, a lot of the advantage is lost. I wish someone like
SuperMicro would offer a high end Opteron SuperServer. I love their dual
Xeon systems.. I read a rumor they were going to and emailed them to inquire
and was told nothing of value...
Thanks!
