Lun limit with Solaris 10?

So, I'm not sure where else to put this, but you guys on the EMC forums have always pointed me in the right direction. 

Anyway, we have a bunch of clustered Sun servers connected to a DMX.  Each host has 2 HBAs and we have about 400 luns assigned dual-pathed with PowerPath.  Total, including the emcpower devices, in format is 1159.  This is a 7-node database cluster that is maxing out 4 DMX ports when we do weekend maintenance.  We are planning on adding 2 more ports and, instead of just having 2 paths per lun, we're looking to have all luns visible down all paths.  That'll make it around 1200 devices visible per HBA (400 devices, 3 paths per device per hba) plus the additional 400 emcpower devices for a grand total of around 2800 devices.

Does anyone know Solaris 10 well enough to know if this will work?

If it matters, we're using the Sun drivers on Sun branded Emulex HBAs.
