Hi,
I am working with an elementary school who wants to upgrade their Sun
servers to significantly improve the performance of their Sun Ray
installation.
I want to stay with Sun SPARC/Solaris based servers and need to
support up to 70 to 90 Sun Rays. My question is what new Sun server
(or servers) would you recommend for an optimum (performance-wise)
installation. I also want to set up some sort of RAID configuration
at least for the student's and teacher's home directories.
Current configuration is a Sun Blade 2000 as a NIS master/home
directory server and a pair of SunFire 280Rs as the primary and
secondary Sun Ray session servers.
Is there a reason you want to stay away from the Opteron machines? I've
got 2 Blade 2500s running as a pair of SRSS servers, and I've also got a
X4100 (Opteron/Solaris) running, and the opteron box is way more
responsive and usable then the Sparcs.. I would agree with the choice of
Sparc as the fileserver, and NIS server (although, 3 machines can easily
enough be done by keeping passwd,group and shadow in sync at a files
basis, and removes a point of failure) 2 of the 4100s with 8Gb of ram
would be a good backing for this setup.. and easy enough to add another
machine into it if you need the capacity down the road, which strongly
depends on what the workload you are putting on them is..
Actually, if you can get access to it, you can look at SamFS/QFS and
have a shared block device (iscsi or fc) between the sunray servers, and
eliminate the need for a fileserver as well.. but this may be adding
undue complexity to the setup.
