That is great news. So each backend system does its own auto deletion
calculations based on space available in the local /video file system?
Don't know; have enough space that I don't need to auto-delete.
I believe the answer is yes. However, the disk that fills up
may not have the oldest files so it's a bit unjust.
So which is the preferred setup? NFS or local storage on slave
backends?
Personal choice. I use NFS because my masterbackend has all the
drives; my slaves are diskless backends / frontends.
And I use local disks to reduce network traffic and latency and
I don't want to spoil recordings if there are network interuptions.
Any calculations on how many streams a 100Mb LAN connection
can support?
Lots, most likely. Certainly on the order of the number of units
you'd find in a typical home. Depends on the bitrate of the content.
The easiest way to calculate throughput is that 1MB/sec is 3600MB or
3.6GB/hr. My Default profile recordings are 1.7GB/hr so ~1/2MB/sec.
7GB/hr HDTV would be ~2MB/sec. 100Mb can carry on the order of 10MB.
