Pipeline media Storage
When deciding on storage, there are two main factors
to consider - the overall sustained read/write perfor-
mance required and whether local data disk buffering
will be required.
To ensure performance and quality, the disk storage
system(s) used with the Pipeline host computer must
be able to meet the demands of reading and writing
one or more real-time SD and HD media streams.
There are many disk system setups that can provide
this level of performance.
For SD, we recommend that the Pipeline host's disk
storage system provide and maintain a sustained 10
MB/sec transfer rate per stream from the Pipeline host
computer to the media disk (read/write).
For DVCPro HD, ProRes 422 and standard quality
DNxHD, we recommend that the Pipeline host's disk
storage system provide and maintain a sustained 40
MB/sec transfer rate per stream from the Pipeline host
computer to media disk (read/write) for each stream.
For ProRes 422 HQ and high quality DNxHD, we
recommend at least a 50 MB/sec transfer rate for each
stream.
Four (4) channel Pipeline HD with direct attached Fibre RAID storage
To evaluate your needs, you must first take into account
the data rate for the format that you'll be using and the
number of streams your system will be capturing
concurrently. The table below provides approximate
data rates for a variety of formats and resolutions. Use
these tables to calculate the overall read/write perfor-
mance requirements for your main storage disk system
and if needed for your local data buffering storage disk
system.
Using a disk benchmarking tool as ATTO's Bench32 for
Windows and DiskFire for OSX make sure the media
storage system can accommodate the total bandwidth
necessary, both read and write.
Capture only, writing to internal or direct attached
RAID array: For systems utilizing internal or direct
attached storage for capture only operations you need
only calculate the overall write speed requirements.
Configure your media storage array based on the write
performance needed for the number of streams being
captured.
