3510 with 2 server DAS configuration
So I am getting a 3510 and an 880 and a v490 both with 1 dual channel HBA each. From the docs, it appears that I want to use Point-to-Point connection. I want to use mpxio and take advantage of the dual controller in the 3510. So, I am thinking:
Attach 880 HBA1 to Port 0 on top controller.
Attach 880 HBA2 to Port 5 on bottom controller.
Attach 490 HBA1 to Port 4 on top contoller.
Attach 490 HBA2 to Port 1 on bottom contoller.
Create 2 RAID5 LDs with 2 global spare drives and carve out a LUN to present to each server over their respective channels. Configure Solaris 10 for mpxio.
Sound good? Anything I am missing?
All help appreciated.

I like you plan.. But port 5 should normally be on the top and port 4 is on the bottom. The port numberings go from left to right. So, if you have your setup, move them as that is pretty much what Sun do with their EIS setup.
Ignoring expansion ports, the top controller has ports 0 (far left) and 5 (far right) and the bottom controller has ports 1 (lower right of port 0) and port 4 (lower left of port 5).
On the 880, attach to 0 and 1
On the 490, attach to 4 and 5.
Therefore, you have redundancy if one controller fails which is not unusual.
You should also do lun masking to stop both systems seeing the other systems luns.

Joe,
EIS is the standard Sun uses during installations. I think it stands for Enterprise Installation Services or something like that. Basically all systems are setup to the same level. EIS patches can be a couple of months old but there is a reason for that as they are tested fully (supposedly) before being put on the EIS media.
LUN masking is part of the controller options. Basically you can put in the World Wide Number (WWN) of the HBA's that you want to communicate with that particular LUN.This is particularly useful in sharing your storage and maintaining data integrity.
An easy way of getting your hosts WWN (be it port or node number) is to do:
prtconf -vp | grep wwn
which will show your port or node WWN.
The doco on docs.sun.com explains LUN masking and it is easy to setup.
HTH!!
