DR consideration when building a SAN

When building a SAN, what are the DR considerations? Do you need a separate SAN for DR or a NAS?

If you're going to replicate your SAN for DR, then you may want to consider an iSCSI-capable system, which would allow you to use SCSI over IP. This would allow SAN-based replication for DR. As to NAS or SAN for the DR site, you would want the same as you have for production. HOWEVER, you might want to consider IDE-based arrays for the DR site as they offer reduced speed/etc. but same capacity as SCSI/FC disks.
