I want to stream 3 live channels.
Input:
-
3 x HD 1080i, 25 fps, 12 mbps, mpeg-4 or
-
2 x HD 1080i, 25 fps + 1 x PAL (768x576, 25fps, interlaced), mpeg-4
Output:
-
3 x HD 1080p, 25 fps,
-
each channel in several qualities: 0.5, 1, 2, 4, 8, 12 mbps.
-
Average quality could be 4-8 mbps per channel
-
Number viewers: 100-1000
We consider using a HP DL380 G7 rackserver with:
-
2 x Intel Xeon Six Core X5670 (2.93 GHz). 12 Cores in total
-
64 GB RAM
-
3 x 1.2 TB GB SAS (2½") 10K Hotswap HDD
-
Smart Array P410i with 512 MB RAM (RAID 0,1,5,10)
-
4 x 1 Gigabit Ethernet. Or maybe 3 x 1 Gigabit + 1 x 10 Gigabit when more than 3 Gigabit is required, for example when more than 375 viewers with 8 mbps.
My questions:
-
It is recommended to use 3.00 GHz and 2 x 4 Cores. Is it possible to use 2.93 GHz when 12 Cores ? Or asked in another way: can the 12 cores compensate for going below 3.00 GHz as recommended ?
-
How much harddisc is required when only live streaming and transcoding live channels ?
-
Is Wowza able to live upscale 1080i to 1080p ?
