disk controllers w/ 64-bit addressing?

[James Van Artsdalen]

This is not exactly an authoritative or complete answer from
HighPoint, but it does suggest there's hope for an (relative to SCSI)
economic means of a disk system that doesn't need bounce buffers.

Does anyone in FreeBSD already have a contact at HighPoint or should
I nag them to cough up a datasheet for whatever IC is used?

The pictures show eight SATA ports and one control IC with no
ATA-to-SATA adapter chips in sight, so this probably isn't one of the
chips listed on their site but rather something new.

Dear Sir / Madam,

Thanks for your contacting us!
The current driver for RR1820 only can work on the 32-bit OS.

If you use the 32bit OS on Opteron, RR1820 can work properly, for Memory 
Addressing, it is determined by the operating system directly.

The 64bit-driver(Support 64bit OS) will support 64bit addressing, but it 
hasn't released yet.
