Installing Dante Domain Manager


Hello! I’m Patrick Killianey with Audinate. In this video, we’ll talk about installing
Dante Domain Manager. First we’ll prepare for installation. Since we know some
people will be setting this up with little to no experience with network
servers, we’ll begin with a brief tutorial on things like bare-metal,
hypervisors and virtual machines. Now from there we’ll talk about system
requirements and we’ll offer some thoughts on computer hardware. The second phase is to go through a bare-metal
installation from beginning to end. We’ll
show the basic connectivity screens on the server itself, as well as the operational
screens accessed through a web browser. We’ll get the server licensed and recognizing
Dante devices. Finally we’ll point out the core maintenance
steps. We’ll show how to
update the server, back it up, restore it and deauthorize it. Put it all together,
and you’ll be up and running with a basic Dante Domain Manager server in no
time. So let’s get started. When you install, one of the first questions
is whether you want to do a bare metal installation
or use a hypervisor. We’ll
start by explaining bare metal. And let’s approach this by thinking about
the structure of a personal computer. We start with some hardware and the
associated BIOS. The BIOS is the lowest level of firmware that
presents the hardware in a recognizable way to the operating
system. The operating system
offers a library of resources to the applications. The operating system will
handle drawing Windows, working with certain file types, navigating internal
and external drives, that sort of thing. And of course, modern operating systems can
support multiple applications running at the same time. This is essentially a bare metal installation
of an operating system. The operating system is sitting directly on
the bare metal of a machine. If we’re dedicating a computer to run Dante
Domain Manager, a bare metal installation is really the easiest way
to manage this. And since Dante
Domain Manager is a permanent asset on the network, this really reduces the
temptation to tinker with the machine. Dante Domain Manager is downloaded as an iso
image that will load the operating system and Dante Domain Manager application
on your target machine all at once. In this video,
this is the installation we’ll walk through. An alternative to the bare metal
installation is the use of a hypervisor. To explain this, let’s go back to the personal
computer idea. When Apple moved the Macintosh platform from
the Motorola PowerPC to an Intel chipset, that represented an opportunity. Mac users could now use the same hardware
to run Mac OS or Windows. Apple even offered a tool called boot camp
allowing you to boot into one OS or the other. The only problem was you could only run one
at a time. A more flexible option used by many today
is a type 2 hypervisor. VMware Fusion or Parallels desktop are popular
options. So these are software applications that create
a virtual machine. Basically, they simulate the hardware and
the BIOS. From there you can install an operating system
on the virtual machine. Now to be clear, you’re not running Windows
and Mac OS right next to each other, right? There’s a structure here. When we have a hypervisor running as an application
on an operating system, we call that a type 2 hypervisor. Now if we wanted to, we could put something
else in that virtual machine like Dante Domain Manager. Now I would discourage you from running Dante
Domain Manager on a machine that you’re going to use as a desktop or a laptop. Dante Domain Manager needs to be a permanent
asset on the network. And you don’t want it to disappear every time
your computer hangs up, or performs a routine system update. A better way to manage this is to eliminate
the complexity and weight of the underlying operating
system. And that brings us to a type 1 hypervisor. In this case the hypervisor sits directly
on the hardware. Now of course, both type 1 and type 2 hypervisors
can host multiple virtual machines, all managed from a single
interface. So one thing that’s really nice about this
arrangement is that if you have to update one of these services, the hypervisor can
restart only that virtual machine. You don’t have to take down the other services
at the same time. That’s a nice feature. Okay, so that offers a bit of explanation
on bare metal installation versus hypervisors. A bare metal installation
really means you are dedicating the computer to running Dante Domain Manager. It’s the flattest, easiest installation you
can do. A hypervisor is a service that allows you
to put multiple applications on the same server hardware and is a nice feature. There we can restart the virtual machines
independently. Now of course we recommend reading the Dante
Domain Manager instructions. But this video should offer a pretty good
push start on the bare metal installation. If you’re gonna go the hypervisor route, this
video will offer some of the instructions, but we do have additional guides that will
explain VMware, ESXi, VirtualBox, and Microsoft hyper-v. Okay, so next let’s talk about choosing
hardware. Realistically, with modern computer hardware
you’re probably gonna have a hard time not meeting these system requirements, right? But keep in mind that these are just minimums
if you’re going to have a very large Dante network, or if you’re going to use more advanced
features in there, you’d probably want to dedicate more resources to the server. And this brought up an interesting discussion
in preparation for this video. What type of hardware do we recommend? Well, I think we concluded we can’t just tell
everybody “hey, go buy this particular machine, it’ll be great”. If we did that, we’d have to design a machine
for the largest installations, and then the more simple installations would have a machine
that’s gross overkill. However, we did come up with some basic advice. The Intel NUC is a small form-factor PC. You can build it yourself. And a modern Mac Mini would be another option
in this category. Now you may have seen us use these at demonstrations
or trade shows. Realistically, we chose them because we need
something we can travel with, right? Something we can carry on the plane, plus
if the hardware gets damaged while we’re on the road, replacements can be found immediately
at local electronic stores. And also, when we’re doing these demonstrations
we’re not usually separated from the computer hardware. So the fact that these will run quietly is
a real benefit. These are all positives. I can see this type of hardware for a modest
theater, or a small Church, especially if they’re going to do a bare-metal installation. If a Technical Director just wanted to keep
everything in a familiar wheelhouse, especially if they’re an all MAC house, I totally get
it. However, I think it’s worth encouraging everyone
including audio professionals to consider traditional server hardware. While the fans can be noisy, some might say
that’s the sweet sound of uptime. So in your designs the two things you’ll want
to consider are the depth of the chassis and the noise, right? But since Dante Domain Manager doesn’t have to be in
the rack with all of your other gear, and it just needs to see it on the network, you
can put the server back in an equipment room or something like that. But as we said, the benefit of a traditional
server is uptime. It isn’t just about having reliable components. These machines are often designed with redundant
power supplies and drives and raid arrays. So in the event of the most common hardware
failures, this machine will probably just soldier on. It’ll probably give you an alert to let you
know that some redundant part needs to be replaced, and in some cases, those parts may
be hot-swappable. So you don’t
even have to turn the machine off. All of this points to more uptime, which is
incredibly valuable especially in installations where you’re not running multiple machines
in high availability mode. And of course traditional servers offer massive
scalability in RAM, hard disk space, and so on. This is especially great if you’re looking
to run other server applications on the same machine. So at Audinate we don’t really want to tell
you what machine to buy, just like we don’t want to tell you what network switches to
buy. Now that you have a bit of information about
the benefits of each platform, choose something that will fit your need. With the hardware requirements considered,
let’s get to installation. We’ll walk through four basic steps. First, we’ll show you how to take Dante Domain Manager
iso files and make a bootable drive from it. We’ll show you how to do this on Windows and
on Mac OS. Then we’ll go through the process of a bare-metal
installation. It’s pretty simple, but there are some tips
that will be helpful. From there we’ll take a quick tour of the
server’s native menu so you know where to set the server’s IP address. And we’ll log in with a web browser to license
the server. To make a bootable drive on a Windows machine, you’ll want to use a program like Rufus. Now Rufus is a free download. You can get it from rufus.ie, and once it’s
downloaded you don’t even have to install it on your machine. You just double-click it and it will launch. So here is my Dante Domain Manager ISO file
on the desktop, and my download of Rufus. I’ll double-click to launch Rufus. Windows is asking me if I want to run this. I’ll click yes. At the top, I choose my flash drive as the
target. Here I’ll select the Dante Domain Manager
ISO file as the source. The rest of the settings in the middle should
update automatically. Now this is important. We don’t want to write in ISO image mode. Choose to write in DD image mode. Then click OK. We’ll get one more warning that we’re about
to erase the thumb drive. Click OK to get past that. Now this process will probably run for a minute
or so. I’ll fast forward towards the end where the
program will show it’s 100% complete. But we don’t get a close button. It says cancel. That means it’s not done yet. It’s still working. Wait for the program to finish. Safely eject your thumb drive and you’re done. Now for the Macintosh, it’s going to work
a little bit different. We’re going to show you how to do this from
the command line. And to do this you’re going to need administrator
access to your machine. If you look in your Applications folder, you’ll
find another folder called Utilities. In there, launch Disk Utility. We’ll choose our flash drive. Select Erase and choose to format it as ms-dos
fat. Click Erase and wait for the process to finish. Next, go back in the Utilities folder and
open terminal. The first
command you’ll want to type is diskutil list. This will get you a list of drives on your
computer. Here we can see the flash drive is shown as
disk 2. We can see it’s an external drive and we see
its size and its name. So as we go forward we will be typing disc 2 to reference our flash drive. But obviously you will substitute your disk
number when you’re doing this on your machine. We’ll need to unmount the flash drive to write
the ISO image to it. To do that, type disk util unmount disk / dev
/ and your disk number. And we see the drive disappear from the desktop. Now we need to copy the iso image to that
thumb drive. Type sudo DD if=then drag the DDM iso image
to the terminal window to capture the path of the file. Then type
of=/dev/R and follow it with your flash drive disk number. Press ENTER for that command. Then you’ll be
prompted to enter your computer’s administrative access password. Do that and the process will begin. Now this can
take a long time. It took about 10 minutes on our machine, and
you won’t get any feedback throughout the process. Don’t assume your machine froze, okay? if
you want to get some feedback you can press ctrl T and it will start giving you updates
as this goes through. When the system is done, a pop-up will appear
saying ‘the disk you inserted was not readable by this computer’. That’s what we want to see. Click eject, pull the flash drive from the
Mac and you’re done. So now that we have our installation thumb
drive, we’re ready to do a bare-metal installation. Now obviously this is going to erase anything
on your computer’s internal hard drive. So if you have
anything you want on there, now is the time to back it up. Once you’ve done that, insert your thumb drive
into the machine and boot it up. If your machine isn’t set to prioritize external
boot drives, you may need to change that preference. On a Macintosh computer press the alt or option
key on your keyboard to access the boot drive menu. On a PC you’ll be looking at the startup screens
for what key to press to access that menu. Once you’ve successfully booted from the flash
drive you’ll be presented with the options of just jumping right into the installation
or running some tests first. In this case we’ll just go ahead and run the
installation. Now if anybody runs into a problem at this
point it usually falls into one of two camps. If your computer’s internal hard drive is
in some esoteric format that our installer can’t recognize, you may have to restart your
machine with the Disk Utility, format the drive and then come back to your flash drive,
and everything will be fine. The other possibility is that you may not
have set up your flash drive correctly. For instance, if you went into
Rufus and forgot to tell it to write a DD image instead of an ISO image, that would
also fail part way through. Other than that should be smooth sailing. Now I’ll fast-forward a little bit. When it hits this point where it says running
post installation scripts, it will be here for a very long time. Just let it finish. As a matter of fact, it may be here so long
that a screensaver kicks in. Now how do you know when it finishes? Now because certain keys on the keyboard will
affect the installation process, I can tell you that if you just press the spacebar, things
will come back, and you’ll be able to move forward from there. At the end, the system will report installation
complete. Press return to
quit. Okay, so we’ll do that and we’ll restart the
machine. Now when you do this on your machine it’s
a good time to remove the installation flash drive, and if you have not set up your computer
with internet access, now’s the time to do it. Now that we have Dante Domain Manager installed,
we’ll see it go through these boot up screens. Now I’ll fast-forward through this so we can
take a look at the server’s built-in menu system. At the top of the menu you’ll see the IP address
that the server has resolved to. Now by default this will be set by DHCP, and
we’ll talk about this later in the video. But chances are you’ll want to make this a
static IP. To do that go down to menu number number three. Once you have your machine addressed as you
like, use that first menu item to make sure that this server can access the internet. We’ll need internet access to license the
server. Now if that checks out, we’re done with the
server itself. We can go to a laptop or a desktop, open a
web browser and finish the configuration from there. If you’re on the same subnet as the server
itself you should be able to access it by going to DDM.local. Your computer should resolve this using MDNS. On this screen, we’ll thoroughly read and
accept the end-user license agreement. And if you have a TLS certificate for secure
web connections, put it in here. Now if you don’t have a TLS certificate or
if it’s going to come later, that’s okay. We can skip this step for now. If you want to add one later you can, and when
we get to the server maintenance portion we’ll show you where that screen is. Here we choose the reason for the installation. Since we’re setting this up for the first
time, we’ll choose fresh installation. Later in this video we’ll show restoring a
server. Now if you’re going to be using high availability
mode in Dante Domain Manager, your primary server is still set as a fresh installation,
so you can still go down this path with us. But we will have a
separate video where we’ll talk about setting up your secondary and your
arbiter machines. That’ll be covered in a separate video. Next, select your role. If you’re a contractor setting this up for
somebody else, choose third party. If you’re setting this up for yourself or
for your organization, choose end customer. Now we create a password for the primary administrator
of this server. That
username will be admin, but the password can be whatever you make it here. At the bottom of this screen you can generate
a recovery code to recover the password of the administrator. Store it someplace safe. Maybe you’ll store it with the Dante Domain
Manager license and so on. With that saved, we go to the next step. We’ll enter our Dante Domain Manager product
key. And of course for this to authorize we’ll
need to have a valid internet connection. To be clear, we only need internet access
for Dante Domain Manager to authorize, deauthorize or update the machine. Once you’ve done that, you can take the machine
offline, put it on a network. That doesn’t have internet connectivity and
things will be ok. If we want to choose a different domain name
than the default we can do that here. I’ll leave it as DDM.local. Finally, we have to create the first domain
for Dante Domain Manager to use. The server needs at least one domain. I’ll name mine auditorium, and voila! our
Dante Domain Manager server is all set up and ready to go. So we’ve checked off installation. Now let’s quickly talk about enrolling Dante devices. If you saw the introduction video to Dante
Domain Manager, the “In-Depth tour”, you already know a bit about
the unmanaged domain, moving devices between domains and things like
that. So in this section we’re going to put a little
bit of meat on that. If I look in the devices tab of Dante Domain
Manager, I can see my devices are showing up in the unmanaged group. Down below, I have the domains that I’ve made
for this demonstration. But here I can see I have devices in the 192.168.1
subnet and another group down here in the 192.168.2 subnet. Now depending on your network configuration
Dante Domain Manager may only be showing you devices in the same
subnet as the server. It may not see the devices in another subnet. Let me explain. Here we have a VLAN with Dante Domain Manager
and our Dante devices. Dante Domain Manager, just like Dante controller,
can use mDNS for discovery. But this will only discover devices within
its own subnet. If we add another VLAN to the network, we’ll
need a router to get traffic from one subnet to the other. When Dante devices in this subnet try to use
mDNS for discovery, it won’t cross the router. The little m in mDNS stands for multicast. And multicast does not cross a router. To solve this problem Dante Domain Manager
can use DNS SD to recognize all of your devices across all
of your subnets. But of course that requires a DNS server which
is a little bit more than we want to get into in this video. If you have a situation where you just need
a few devices linked in, it can be very simple to just manually link them to Dante Domain
Manager. Let’s show you how to do that. What we do is, we tell Dante Domain Manager
what IP address the other devices are using. Dante Domain Manager will then establish a
link using unicast, which can cross a router. The Dante device will then remember where
to find Dante Domain Manager and it will make the link back using unicast. And now they’re working together. Now Dante devices are going to memorize the
IP address of the Dante Domain Manager server. That’s why earlier in the video we said it’s
a really good idea, if not a requirement to set the server to a static
IP address. Now let’s show you how to manually link things
in. To manually discover devices you can click
on enroll devices at the bottom. At the top you can choose the domain you want
to move the devices into. Click on enroll by IP address and you can
enter the IP addresses of your devices. If you have a few just put one on each line. If you have a massive list, you can also import
them from a CSV file here at the bottom. Now once Dante Domain Manager recognizes your
devices we can move them between domains in a number of ways. In the
introductory video we showed you drag and drop, which is certainly easy with a limited
number of devices. But as your listed domains and devices gets
longer, it becomes a bit unwieldy. It can be nice to have a more direct method. You can also select the devices in the list
and click enroll devices. In either pane. Again we’ll see the domains
in a drop-down list. Click enroll to make that happen. I’ll do this
once more for the devices in the auditorium and I’m done. So at this point we’ve got Dante Domain Manager
installed, licensed, recognizing our Dante devices and we’ve put them in the appropriate
domains. Now the one thing we haven’t addressed yet
is clocking. Setting up clocking is actually fairly easy,
but you have to understand what you want to do before you do it. And for that amount of explanation we felt
that was best handled in another video. So look for the video on clocking. At this point I think it’s worth wrapping
up this video with a few maintenance functions you’ll want to use. When we originally set up the server, we said
that you could add the TLS certificate later. That is available in Settings –
Network and Security. You’ll be able to add it here at any time. Another handy feature, if you remember when
we were setting up the server we were able to test to make sure the server was able to
access the Internet. That feature is available through the web
browser as well. It’s right in this same screen. Settings – Network and Security and click
Run Diagnostics. So this is a handy test to run anytime you
want to authorize, deauthorize, or update your machine. Now another helpful feature is the ability
to backup your server. Now one of the nice things, we don’t have
to backup the entire hard drive. We can save just the configuration of this
Dante Domain Manager so it uses much less data. Conveniently, the server will tell you any
time the configuration has changed. So you can consider backing it up then. To download the server configuration go to
Settings – Updates and System Information and download the system configuration to your
machine. Now when you download this make sure your
computer is saving it as a tgz file or a tar.gz file. Effectively this is a very particular type
of zip file. And some web browsers thinking they’ll be
helpful automatically unzip the file for you. Now that’s not helpful for us, because if
we’re gonna send this back to Domain Manager to restore the server at some point, it needs
the zipped format. If somebody didn’t realize that they downloaded
it and their server unzipped it, you can just re-zip it. But make sure you use that format right. It’s the gzip format. The GNU zip – if you do that you’ll be fine. Now the other thing that could happen is if
you’re restoring your machine because the hardware failed, you won’t have the opportunity
to deauthorize the machine, right? You can try going ahead and installing it. Sometimes the licensing server will automatically
let you go through, but if it doesn’t you can give us a call and we will reset that
key for you. So let’s walk through restoring a server. Effectively you’re going to start with a fresh
installation. When you login with the web browser, you’ll
do the same first few steps, accepting the user agreement, and addressing the TLS certificate
if necessary. When you get to the screen asking what type
of installation you’re doing, you’ll see an option to restore a configuration. That’s what we want. Drag your configuration in and once the screen
shows it’s ready, upload it. Once that’s done we can log in and re-enter
the product key to reauthorize the server. Of course this step needs internet access
to reach the license server and once that’s done we’re back in business. And finally that brings us to deauthorizing
the server. Now why would we deauthorize the server? Well let’s suppose you’re going through a
planned hardware upgrade. You can deauthorize your old machine, recovering
the key, and then reinstall it on a new machine. To deauthorize Dante Domain Manager, go to
settings – license management, in here you’ll see the current license for Dante Domain Manager. Click to deactivate. It’ll take just a moment. So that about wraps up this video. We’ve explained the server structure including
terms like bare-metal, hypervisor, and virtual machines. We’ve also had a short discussion about choosing
the right hardware for your system. We completely walked through the bare metal
installation. And remember, if you’re going to use a hypervisor,
we have guides to help you through several popular options. We licensed the server, recognized our Dante
devices, put them into domains and we walked through some of the basic maintenance processes
related to the server. At this point you are ready to set up your
Dante Domain Manager server. Thank you for joining us, and we’ll talk soon!
