							secondary DR550

Note: Zone 3 is configured for use with tape (TS1120, LTO Gen 3, or 3592 drives with WORM cartridges are recommended - ports 5-7 are available to connect to tape drives)

Zones 4 & 5 are configured for use with data replication (DS4100 enhanced remote volume mirroring)

Per IBM recommendations, the ports used to connect the switches are not included in the zones for remote mirroring

These zoning configurations may be needed if you ever need to rezone the 2005-B16.

For more information, 2005-B16 data sheets can be downloaded from:

Should one of the switches fail (dual node configurations only), the logical volumes within the DS4100 systems are available through the other controller and switch.
