Hi Kim
Take a look at this section of the docs -
http://docs.sun.com/source/817-6806/failover.html#84345
'Ideally, each server would have an address for each DTU. '
In your case a Class B network would work best, with each server having at least 1,000 addresses available for DTUs.
In your example, if one server fell over, the remaining servers wouldn't have spare addresses for the 100 DTUs that had lost their connections and needed to reconnect.

Yes. It's explained in detail in the docs, but... Assuming we are using smartcards or non smartcard mobility, a user inserts a smartcard or logs in and the servers pass tokens around, talk to eachother and direct the DTU to the server running an existing user session, or create a new one if no session exists.

Sun Ray Server Software just handles displaying a Solaris session on a Sun Ray device. Managing user names and passwords, file sharing etc, is normal Solaris stuff (I'm assuning you're using Solaris - same goes for Linux though).
In your case, assuming users are running Solaris sessions and using Solaris applications, the ideal way would be to have a separate NFS server, preferably clustered, given the large number of DTUs. For managing usernames you could use LDAP or NIS. NIS could run on the file server(s), as could LDAP.
Which country are you based in? This sounds like a large and potentially complex deployment - your local Sun team should be able to help.

Hi,
Now we have some project for using almost 1,000 sunray DTU with SRSS 3.
I am new about sunray system. There is some question about design Sunray network system.
In Administrator guide show two type sunray fail over group.
First, when I use Sunray failover group, that group share all session info? So Any one can access any DTU with same session?
Second, My thought for 1,000 DTU is(each Sunray Server cover 100 DTU, and 10 Sunray Server with one failover group)
Sunray Server 01 --> 192.168.1.1 --> Switch (for failover group)
--> 192.168.2.1 --> Switch (for 100 DTU 192.168.2.10 ~ 192.168.2.110)
Sunray Server 02 --> 192.168.1.2 --> Switch (for failover group)
--> 192.168.2.2 --> Switch (for 100 DTU 192.168.2.111 ~ 192.168.2.210)
Sunray Server 03 --> 192.168.1.3 --> Switch (for failover group)
--> 192.168.3.1 --> Switch (for 100 DTU 192.168.3.10 ~ 192.168.3.110)
.....
Sunray Server 10 --> 192.168.1.10 --> Switch (for failover group)
--> 192.168.6.2 --> Switch (for 100 DTU 192.168.6.111 ~ 192.168.6.210)
That is my simple thought. Do you have any suggestion?
Last, in order to share user account info( disk and password) within a fail over group, is there need some kind of LDAP and NFS solution? or SRSS cover all of them?
Thanks
Kitae
