Network Zone Configurations
36
A client uses mechanisms specific to the operating system to display, create, and delete files
within the Avid ISIS shared storage network system. For example, when viewed from a
Windows operating system, the system sees a server containing many shares that are mapped to
drive letters.
Network Zone Configurations
All clients in the shared storage network are classified by zones, depending on how they connect
to the network. The following list defines the clients in each network layer by their zone
classification:
n
A System Director must be attached to both subnets, but can only be attached once to each
subnet.
•
Zone 1 Client — Connected to ISIS VLANs via an ISS 1 Gb or 10 Gb port (direct connect)
•
Zone 2 Client — Connected to ISIS VLANs via a 1 Gb or 10 Gb port on an Avid qualified
layer-2 switch (non-routed)
•
Zone 3 Client — Connected to an Avid qualified layer-3 switch (routed) with known Quality
of Service (QoS); traffic routed to ISIS (one hop) and load-balanced across ISIS VLANs
(approximately a 60/40 ratio)
•
Zone 4 Client — Connected to the house network using an edge or a core switch with
unknown QoS; traffic routed to Avid ISIS (measured by the number of hops) and
load-balanced across ISIS VLANs (approximately a 60/40 ratio)
n
Clients which can connect to one zone can run in any lower-numbered zone — for example, a
Zone 3 client can also run as a Zone 2 or Zone 1 client.
Support for different client and device types vary by zone:
•
Zone 1 — AirSpeed playout, Transfer Manager
•
Zone 2 — AirSpeed ingest, editors, Interplay
•
Zone 3 — Instinct, Assist, certain editors (for example, Avid NewsCutter); typical formats
include DV25, DV50/IMX-50, MPEG-2 proxy (2 Mb/s)
•
Zone 4 — Instinct, Assist; typical formats include DV25, MPEG-2 proxy (2 Mb/s)
The following four examples show different types of Avid ISIS 7500 | 7000 configurations.
