I think the limit is 1024 cores. Or was that fixed to allow more?

As for ram that really is a cpu/architecture limit and you won't be
able to find a motherboard that supports as much ram as the cpu(s)
could handle.

More than 1TB on disk? Doh. 1TB fits on a single disk. Anything up to
16 TB is quite trivial. Beyond that you start to hit the limit on
filesystem size with ext3 and have to use xfs or ext4 or something. Or
you have to partition the space iinto 16TB chunks. Also > 16 disks
requires a big enough case or external storage. For that I would look
into external enclosures with SAS connector. Don't use SCSI or FC.
