Ceton 6 ETH bandwitdth questions or go with 4 USB

#1

I did a search and didn't find anything that fit perfectly.
This is my current setup.
Zotac ZBOX AD03BR Specs
AMD Dual Core E-350 (1.6GHz) onboard Proc
Radeon HD6310 onboard video
8GB DDR3-1066
120 GB SSD (OS and installed software only)
1 Gb NIC
ISCSI connection using existing NIC to a 1TB LUN carved out of an 8TB NAS to create local drive for Recording TV
Mapped drives for Video/Movie/Music/Picture on SAN
Hauppauge WinTV-DCR-2650
Extenders
1 Linksys DMA2100
1 Linksys DMA2200
FIOS TV

I have no way to install a PCI-e card because my Media Center is an all in one the size of a DVD player with no free slots.
I would like to go to at least 3 tuners, as that is the most I have ever needed at one time for recording. We rarely ever watch live TV but often there are 3 shows we want to record.

What I was wondering is would I be taxing my single 1Gb NIC by having the tuner data, network traffic and iSCSI traffic all trying to occupy the same space? Does anyone have any idea what kind of bandwidth the tuners use when playing HDTV?

Would I be better going with a Ceton 4 USB if I can find one?

Thanks,
Jeff

It won't max out bandwidth at all. I'm currently running the ETH 6 with an E-350 computer too and it works great.

my worry is not the processor... it is the Network bandwidth since all my files are on Network shares from a NAS. Even my recorded TV is not going to a local HDD instead it is going to an iSCSI LUN on the NAS.(iSCSI tricks the OS into seeing the Drive as local)

Each TV stream will be 15-18Mbps. So, if you are recording 6 simultaneously, that's 108Mbps. Then, you are going to be writing those back out to your iSCSI drive for another 108Mbps. So far, you're up to 216Mbps. You have a gigabit NIC, right?

yes gigabit connected to the same GigE NetGear Pro Switch. So looks like I should be ok.

Yes, I've had iSCSI and 6+ streams going on the network at the same time. As I said, it shouldn't be a problem.

We have 12 tuners, record to a NAS, and have 5 extenders. We rarely reach 50% network utilization
