Remote I/O (RIO) Chassis and Blackrock Processor On-Air Redundancy
In its simplest implementation, a C100 HDS will have a single Blackrock processor and a single RIO unit, connected by
fibre MADI cables with a bandwidth of up to 254 bi-directional audio channels plus control and status data. This
arrangement does not offer any hardware redundancy if either unit (or any of the cables between them) is lost. However,
it can be expanded and configured to provide several levels of redundancy for the audio interface, audio connection and
processor core to suit a facility’s particular requirements.
Redundant RIO link
To protect against the possible loss of a RIO fibre cable, both of the MADI cables between the RIO the and Blackrock
processor can be configured to have a redundant spare, which will automatically become the backup for the primary fibre
cables. This configuration provides a maximum audio channel count of 126 between the RIO and Blackrock, including the
redundant links.
Dual RIO units
If a second RIO rack is required for additional I/O, this can be accommodated without restricting the capacity of a first
RIO. Adding a second Mezzanine card to the Blackrock core will provide sufficient MADI ports for four ports to link to
each RIO (pictured). If the Blackrock is fitted with a single Mezzanine card only two MADI ports will be available to
connect to each RIO.
Redundant Blackrock Processor
For mission-critical reliability a second Blackrock processor can be used as a redundant spare, and connected to a single
RIO if that is all the audio I/O that is required. This will allow the console to continue in the unlikely event that the primary
Blackrock processor is lost. Note that the RIO must now connect to each Blackrock using only two MADI fibres, thereby
limiting the number of audio channels to 126 without redundant link, or 62 channels with redundant link.
Redundant Blackrock Processor and Dual RIO units
In this scenario, the limited I/O capacity of a system with Blackrock redundancy and one RIO can be expanded with a
second RIO unit. Two of each RIO's four MADI connections feed each of the Blackrock cores. When MADI link
redundancy is configured, the system is resilient enough to allow loss of up to 4 MADI connections and one complete
Blackrock core without any loss of console capability or audio.
Any MADI links not used for connection to an SSL RIO may be used instead for connection to any other MADI equipment,
including other manufacturers' Routers and I/O interfaces that comply with the AES10 specification for MADI. This
includes redundant links to those pieces of equipment that support this mode of operation
