Adding Storage
On large systems, (especially with multi-board Mykerinos configurations) most of the PCI 32Bit (Legacy)
bus bandwidth is needed and used by the Mykerinos cards in Pyramix & by Mykerinos & Video output
cards in VCube, so for attaching storage units dedicated to real time media record and playback, we
recommend, wherever possible, NOT using any I/O connection or PCI add-on card that will interfere with
the PCI bus bandwidth.
Determining I/O connections suitable for real time storage:
1. Go
to:
My Computer > Properties > Hardware > Device Manager
. In the
View
Menu, select
Devices by connections
.
2. Navigate
to,
Microsoft ACPI – Compliant System / PCI Bus
, then open any single
node/connection until you locate the
PCI Bridge
where the Mykerinos cards and/or Video output
cards are listed. Any item listed here, directly sharing a PCI Bridge (or PCI-Express root port) with
Mykerinos and/or Video card, such as the 1394a adapter and SCSI card shown in the example
should be considered as non optimal for attaching storage dedicated to real time record or playback
of audio and/or video files when maximum performance is the principle criterion.
