Configuring Considerations for MEDIArray ZX4
When you connect a MEDIArray ZX4 to a Unity
™
MediaNetwork you must
take the following into consideration:
• A MEDIArray ZX4 can connect to a maximum of two MEDIASwitch 16-
4G of the same speed and model. You
cannot have a MediaSwitch 9X00
and a MEDIASwitch 16-4Gb in the same Avid Unity system.
• If MEDIArray ZX4s are the only storage devices you are using, the
maximum number of MEDIArray ZX4s per Unity system is six fully
configured MEDIArray ZX4s. The MEDIArray ZX4s can be configured
in the following ways:
- One MEDIArray ZX4 connected to one MEDIASwitch 16-4Gb port
(see the figure labeled
“Port Layout for 4-Gb MEDIASwitch 16-4Gb”
on page 21 for port connections).
- One MEDIArray ZX4 connected to two MEDIASwitch 16-4G. In a
dual MEDIASwitch 16-4Gb environment each MEDIArray ZX4
would have two Fibre Channel boards. One board in PCI slot 5 and
one board in PCI slot 6 (see
“Connecting One MEDIArray ZX4 to
Two MEDIASwitch 16-4G” on page 23 ).
- Two MEDIArray ZX4s (or a MEDIArray ZX4 and a MEDIArray
ZX) can be looped together and connected to one MEDIAswitch port
(see
“Looping Two MEDIArray ZX4s to One MEDIASwitch 16-
4Gb” on page 24 ).
- Two MEDIArray ZX4s (or a MEDIArray ZX4 and a MEDIArray
ZX) can be looped together and connected to two MEDIAswitch
ports. In a dual MEDIASwitch 16-4Gb environment each
MEDIArray ZX4 would have two Fibre Channel boards. One board
in PCI slot 5 and one board in PCI slot 6. See
“Looping Two
MEDIArray ZX4s to Two MEDIASwitch 16-4G” on page 25 .
The type of cable you use depends upon the type of switch and the
MEDIArray ZX4 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
16-4Gb, the cable needs LC optical cable connectors at both ends.
• If you are looping two MEDIArray ZX4 enclosures to a MEDIASwitch
16-4Gb 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.
