It is possible to connect Navision to SQL servers in 64 bit.

Remember that there are 2 different versions: IA64 (Itanium) and X64 (Xeon or AMD).

SQL 2005 supports both and SQL 2000 only support IA64.

Navision can connect to any of these 32/64 bit. Just use xp_ndo_ia64.dll or xp_ndo_x64.dll on your
SQL server instead of hte xp_ndo.dll.

Client:

Navision 4.01 on 32 bit Windows XP connected to SQL 64 bit on Windows 2003 64 bit

Server Configuration:

Windows Server 2003  Enterprise 64 bit SP1;
SQL Server 2005 Enterprise 64 bit SP1;
Itanium II (2 processors) machine with 8 GB RAM and 1TB 1+0 RAID.
MBS Navision 4.0 SP1 or Better

The number of drives is more important to performance than the total array size.
