dear all
i want to know how to ingest a movie from another doremi server,how to connect servers to each other should i put ip or only network cable can someone explain & thank you all

connect the servers using ETH0 and maybe a gigabit switch (use cat5e or cat6 cables), set an IP address to all machines (I'd use Dolby structure, but it's up to you), then go to Control Panel, Content Feed Manager and add on each server the other server.
When you have finished you will find the other server on the INGEST windows, by the LOCAL INGEST.

Posted by Dave Macaulay (Member # 813) on 01-25-2013, 08:25 AM:

You can do it yourself if you know a bit about computer networking.
You should use a 1000baseT gigabit ethernet switch and cable, 100baseT will work fine but content transfers will be pretty slow (slow like USB ingest).
If you're unsure of the process, get a local computer shop with networking experience to help.
You will need the Doremi server root password.
Server network configuration and setting up the servers for ingest, once the systems are networked, is covered in the Doremi manual.
Don't change the settings on the server ethernet port that's already in use for the screen management network. A few years ago Doremi recommended using eth0 (the port on the left) for the media network: I set up most systems the other way around (network configuration dictated by the owner) and it works perfectly. I think the recommendation may have been for an older model motherboard... whatever, I don't recommend changing ports over it. Best not to screw up what's working now: if you get the port settings wrong on the screen management network (communicating with the projector etc) the server will not show movies until it's corrected.
For a site where an addressing scheme is not predefined, I generally use management on 10.120.10.xxx and media on 10.120.20.xxx (the two networks must be on different segments!), with a 255.255.255.0 netmask and no gateways set. The xxx is just the device and screen number - something like 011-020 for projectors (011 for screen 1, 012 for screen 2, etc), 021-030 for servers, 031-040 for automations, etc. You are free to use whatever network addressing scheme you like on the media network, regardless of the management network settings. However, do not try to use DHCP. You need to have static IP addresses. And the two networks have the same netmask, set in eth0 configuration. If it's been set to something other than 255.255.255.0 there's probably a good reason - don't change it. If it is different and you don't understand the addressing restrictions of a different netmask, get some advice before doing the media network configuration to avoid address space conflicts.

Hi Dave,

I was told that eth1 is 100Mbit and eth0 is 1000Mbit, that's the reason.

thank you Marco Giustini & Dave Macaulay
so it work like this connect doremi server to another by 1000baseT gigabit ethernet switch and cable ,in the content feed manager i put the ip and the subnet mask .the ip should be the same on both server
example 192.168.100.56 sub 255.255.255.0 it work like that

Posted by Dave Macaulay (Member # 813) on 01-27-2013, 07:34 AM:

Both are 1000bT on current motherboards.

Posted by Robertt Haddad (Member # 7421) on 01-27-2013, 07:52 AM:

thank you Mr Dave Macaulay
can we do it without a switch i mean only (by net cable) a cat 5 or 6 cable from server to another direct

Posted by Dave Macaulay (Member # 813) on 01-27-2013, 08:12 AM:

Fine for two servers. If it doesn't work with a standard ethernet cable, use a "crossover" cable.

Posted by Marco Giustini (Member # 4544) on 01-27-2013, 08:19 AM:

Thanks Dave!

great thank you

A Gigabit Switch goes for as little as 20-30US$, and it allows other machines to be shared on the network, e.g. an additional computer/NAS for content storage, remote Control of the Doremis by VNC, tablet, notebook, etc.

You can add it any time later, though.

Just so you know, I just connected 2 Doremi DCP2000 servers together to try it out. I connected the ETH1 ports together with a standard ethernet cable. I manually added the server with the content to the server I wanted to go to through the Content Feed Manager. It works fine. My question is though shouldn't it be a fairly fast transfer going this way?

Posted by Brad Miller (Member # 2) on 02-06-2013, 10:18 PM:

Was either server playing? Doremi does some major speed throttling during playback.

Posted by Richard May (Member # 2627) on 02-06-2013, 10:23 PM:

Both are playing actually. It's been transferring for exactly 2 hours now. It's only up to 31%. 136GB feature I'm tranferring.

Posted by Brad Miller (Member # 2) on 02-07-2013, 12:25 AM:

Start the transfer when both players are done playing. You will notice an amazing difference in speed.

This is a problem with all of the D-cinema servers that use software raids instead of a true hardware raid. You will notice the Dolby DSS200 transfers at full speed all of the time regardless of what it is doing. (Note Dolby's DSS220 is a software raid though. Boooooo.)

Brad,

How big is a typical film? I never thought to look in the days when I was involved in projection.

Posted by Carsten Kurz (Member # 5396) on 02-07-2013, 12:47 PM:

Can be anything between 80 and 300 Gbytes for a typical feature ingest. A DCP/harddisc may contain multiple versions - depending on language version, subtitles, surround sound system, could as well go as high as 500GBytes or more.

HFR doubles it on average, but neither 4k nor 3D (same peak bitrates as 2k/2D)

Posted by Richard May (Member # 2627) on 02-07-2013, 01:27 PM:

After some testing, here is what I noticed......Both screens have the projector, server, and automation controller hoooked up to their own gigabit switch. Switches then connected to each other via CAT6 cable. Doremi server using ETH 0 only.

Transferring a 136GB movie from one server to another while both servers are playing back took over 4 hours.

Transferring same movie while both servers were idle took 26 minutes.

Would using ETH 1 on the server through the same switch with everything else make a difference in any way?

Posted by Brad Miller (Member # 2) on 02-07-2013, 01:43 PM:

Nope, that's just what happens on software raids in these d-cinema servers. They have to throttle incoming and outgoing file transfers to ensure that playback is not interrupted and/or does not stutter.

Posted by Richard May (Member # 2627) on 02-07-2013, 01:48 PM:

Thanks Brad. At least now I know it's normal.

Posted by Robertt Haddad (Member # 7421) on 02-11-2013, 03:06 PM:

hello all please one last question if i connect both server direct with straight cat 5 cable .1 go to content feed manager here my question should i invent the ip or the ip is in the server how can i add it. and the same ip must be on both server plz can someone give me an example

Posted by Robertt Haddad (Member # 7421) on 02-11-2013, 05:03 PM:

dear all this is my question how this works ?
identifier ...
ingest protocol...
server ip ....
username ... password ....
remote path ....
please can someone fill in this

Posted by Dave Macaulay (Member # 813) on 02-11-2013, 09:35 PM:

1: unless it's a fairly short cable (25 feet maybe) you will need Cat6 cable to get 1000Mb/s
2: direct ethernet cable connection (no switch) between the eth0 or eth1 ports on the two servers works fine. Really old DCP2000s ("Intel entry server board" displayed on bootup) you might need a switch in between.
3: you have to set up the ethernet ports on the servers, this is in "system apps" or whatever the bottom choice is, "networking configuration", you need the root (called su for superuser) password. Set these up for no DHCP, address the two servers differently like 192.168.50.1 and 192.168.50.2 with the netmask as 255.255.255.0 and no gateway. If you're not sure what adapter is which, check in device manager for the projector address and do not change the server port with the same first three sets of numbers, if you do you'll have to set it back before it will show movies. When you set the port address for your new cable do not use the same first three sets of numbers as are used on the port connecting to the projector. Usually the third set is changed but it doesn't really matter. You have to reboot after changing port settings.
4: with both servers ports addressed and the cable connected, open "control panel" and start "content feed manager". This opens a window with a list on the left with only "Local Storage" in it. To the right there is a "scan for servers" button. Current software (2.2.5-0) is a bit better than previous versions here, anyway you have to click it: it searches a while and then comes up with a list of connected servers. If you don't see the other server there's something wrong with addressing or wiring. If you see it, click it. The address should be what you set the other server's port to. You may have to fill in the usual "manager" name and password plus "admin" and its password. Then try "test" and it should pop up a window and say "success!". Call the server some logical name where it says "new server" - like "screen 1" for example. Click on "Advanced" and select playlists if you want to ingest them too - this is pretty useful so you don't have to make a new one when you transfer a show but the two server's macros must be identical. You can also select "authorize pngest from this server" if you want, that lets you play a movie while ingesting it from the other server. That may not work so well if the source server is also playing a movie - I haven't tried it. Leave 'remote path" as it is, jjst "\" I think. Click "save" then close the control panel. Repeat on the other server.
If you can't scan, it probably has wiring or address issues but you can enter manually and test -
identifier is the name you give the other server
protocol is ftp
address is the IP address you set for the other server
management name is "manager" with the manager password
administrator is "admin" with the admin passowrd
4: Open the ingest manager ("Doremi Apps", "Ingest"). It will immediately scan any ingest devices attached (USB or CRU) and display what it found. Close the "no content found" window if it opens. Click on "Local Storage" and a pulldown menu will open, select the other server. It will scan that server. Select and ingest what you want.

Just some more random info. I just loaded a 111GB movie via sata connection through the external bay. It took 45 minutes. Server was idle at the time. I then transfered it to another screen via gigabit switch. Both servers were idle. It took 22 minutes.

Posted by Carsten Kurz (Member # 5396) on 02-13-2013, 06:16 PM:

One thing to consider with this approach is that during media ingest, a check/verification is performed, it's not just a copy process. After the dcp has been ingested, network transfers between servers take place without verification, thus go much faster.
