Legacy, Supported MEDIArray ZX Configurations

Configuring Considerations
When you connect a MEDIArray ZX to a Unity
™
MediaNetwork you must
take the following into consideration:
•
A MEDIArray ZX can connect to a maximum of two MEDIASwitches of
the same speed.
•
If MEDIArray ZXs are the only storage devices you are using, the
maximum number of MEDIArray ZXs per Unity system is 6 fully
configured MEDIArray ZXs and one MEDIArray ZX with 8 drives (only
four used for data). The MEDIArray ZXs can be configured in the
following ways:
-
One MEDIArray ZX connected to one MEDIASwitch port.
-
Two MEDIArray ZXs can be looped together and connected to one
MEDIAswitch port.
-
One MEDIArray ZX connected to two MEDIASwitches. In a dual
MEDIASwitch environment each MEDIArray ZX would have two
Fibre Channel boards. One board in PCI slot 3 and one board in PCI
slot 4.
The type of cable you use depends upon the type of switch and the
MEDIArray ZX configuration used. The following cable information should
be taken into consideration:
•
If you are installing the optical cable for use with a 2-Gb MEDIASwitch,
the cable needs LC optical cable connectors at both ends.
•
If you are installing the optical cable for use with a 1-Gb MEDIASwitch
the cable needs an SC optical cable connector at the end going to the
MEDIASwitch, and an LC optical cable connector at end connecting to
the Fibre Channel board.
•
If you are looping two MEDIArray ZX enclosures to a MEDIASwitch
you need three simplex cables. Two simplex cables 3 meters in length and
one simplex cable .5 meters in length. The type of ends on the 3 meter
cables depend upon the switch you are connecting to.
