Zoning Concepts and Guidelines

Hardware enforcement has limitations. Each Quad has 64 SID CAM (Source ID

Content Accessible Memory) entries. All four ports on the Quad share these SID

CAM entries. When these SID CAM entries are exceeded, then the hardware

zoning reverts to SOFT zoning.

For example, a port has taken up 63 SID CAM entries, as it is zoned with 63

devices. Adding two more devices to this zone will cause this port to revert to soft

zoning.

Likewise there are 512 DID CAM (Destination ID Content Accessible Memory)

entries per quad.
