Hello, this is my first message on this site. I have
just be assigned a task to install and configure a
sunray environment for 100 users. Can someone please
guide on the process and steps to take in order to
make this a successful deployment? Any pitfalls to
watch out for.
I have done the installation of SRSS3.0 on S10.
Just make sure your server(s) is/are sized appropriately.
Although it will work over a shared network, I recommend
a dedicated network if that's not unduly difficult.
The hardest task will probably be to gain acceptance among
people used to PCs. Anything new scares some people.
Some things to consider are:
1) Profile your users, what are they running and how resource intensive
are these apps? How many concurrent users do you expect? This will give
you a feel for server sizing but nothin beats running a pilot to see
true usage patterns
2) Determine network options. On a new setup a dedicated network is
easier to troubleshoot, if practical in your environment this is
possibly an easier path to go.
3) Consider resiliency. Do you need failover groups and thus multiple
servers?
4) How soon before you need to reach production? SRSS 3.1 gives the
option to use the x86/x64 systems with Solaris 10 and is out in Alpha at
the moment, this may give you more server options and therefore more
control over you budget.
5) User comfort. Are you going to present the users with Gnome? If so
and they have not seen it before you need to plan for familiarisation of
users (not that there is really any learning curve). Also show what the
SunRay can do. Show video/audio through realplayer, show that Mozilla is
a great browser, StarOffice8 / OpenOffice 2.0 is nearly here and is very
comfortable to transition to from MS Office.
6) Show off hot desking with Java Cards. This is the coolest feature and
definately helps in getting user/management buyin. Also get them to
"listen" to the SunRay and then go back to their PC, They will soon
realise how much noise they are currently subjected to.
7) Keep an eye on performance. With CPU usage hitting 100% things start
to slow down in a very even way. When you start running out of real
memory performance can degrade rapidily due to disk I/O activity. Do NOT
skimp on memory!
8) Make sure you have good support processes in place. A problem on a PC
affects one user, a problem on a server can affect everyone.
