Stefan and SunRay Freinds,
Below is the network and filer configuration
Five Sun Fire 4600s with 8 network interfaces each = 40
-ESX VMSERVERS
Three Sun T2000 with 2 network interfaces each = 6
-Sun Ray Server 4.0
Three Sun X2200 with 2 network interfaces each = 6
-Windows 2003 Enterprise 64 bit/Terminal Servers with applications served
from Softricity Soft Grid
Raritan VGA KVM over IP = 1
-Remote management for 2200 and 4600's
Raritan Serial KVM over IP = 1
-Remote management of T2000's
NetApp 3020 cluster = 4
- Filer 2 control Heads and 4 storage shells
Brocade Switch = 2
- 4GB Fiber Channel switches
Here is our volume plan for the filer.
FlexVol Name # of LUNs VM Size GB VOL Size GB LUN IDs
IGROUP
Walker1 40 25 2,500 101-140 ESX1A
Walker2 20 25 1,250 151-170 ESX1B
Walker3 45 25 2,813 201-245 ESX2A
Walker5 30 25 1,875 251-280 ESX2B
Walker6 30 25 1,875 301-330 ESX3A
Walker7 30 25 1,875 351-380 ESX3B
Walker8 30 25 1,875 401-430 ESX4A
Walker9 30 25 1,875 451-480 ESX4B
Walker10 30 25 1,875 501-531 ESX5A
Walker11 30 25 1,875 551-580 ESX5B
This allows space for each lun + 1 snapshot of each lun + 50% on each
FlexVol. Snap reserve is set to 0% according to best practice.
We use one lun for each VM to allow for maximum bandwidth. This is a best
practice, we did however try and put 10 VM's to a lun, and this had poor
performance.
We also have one network CIFS file share as FlexVol named WHFILES with size
of 1,000GB. We use VIF single-mode with Gb interface connected to two
redundant network switches on each Controller.
There is 1 port on board FC ports of Controller 1 connected to each of the 4
shelves. The on board FC ports of Controller 2 connected to the Out FC port
on each of the 4 disk shelves. The other option is to go Active/Active (1
Aggregate per Controller) with each controller driving 2 shelves.
Active/Active distributes the FC IO across more channels which improves
performance.
For the Sun Ray Server I put all the IP's in the the host table. The
way the user logs into the VM is I put an entry into the .cshrc file that
equates to the user and the appriate VM. As an example if the user is using
vmuser01, the users will login as that user. Vmuser01 will connect to the
RDP VM running on the ESX Server that maps to vmuser01. The ESX Servers are
all clustered, and as we fire up 100 VM's the load is distributed across all
5 4600's. The management of the VM's is done via the VM Console, all users
are domain users and we run one real AD Server and one virtual VM AD Server.
We also run the Sun Ray Servers in Smart Card CAM Mode, if a user inserts a
Smart Card I launch a Windows Terminal Server Session. I use Craig Benders
terminal Server load balancing script, that is available from the Think Thin
Site http://blog.sun.com/ThinkThin/entry/cam_mass_storage_workaround If
you don't know who Craig is check out Blog
http://blogs.sun.com/ThinGuy/category/Sun+Ray
The entire sollution sits in two racks, we will scale to 450 DTU's, and we
are in the process of installing a system to support another 1200 dtu's with
this configuration. The limitation of the ESX Server is not CPU, but memory.
Our Future plans are to migrate to 128GB of RAM, onece the memory becomes
available. If you have any questions or want more specifics let me know.
Take Care

Can you post more information please, I'm interested in whole setup(disk
array, file system, sunray server's, domain ?, etc...)
