One of the dual-channel Symbios 22801 cards would be ideal, or one of the 
PCI SunSwift cards with single-channel SCSI + ethernet (x1032a) will do 
the job too.

Sun supports the 22801 card as the x6540a (and the 22802 which is the HVD 
version of it as X6541a). Both those cards have a pair of VHDCI connectors 
for external devices. Sun also supports single-channel Symbios 8751 card 
(x5010a). The 8951 cards should also work but some of the 8951's have a 
revision of the Symbios ASIC that the 'glm' driver doesn't support.

The 'glm' driver will work with just about all PCI SCSI cards using the 
53c875, 53c876, and related ASIC's. I've tested a varied bunch of non-Sun 
PCI SCSI cards without many problems. Some of the ones which the 'glm' 
driver doesn't work with have 3rd-party device drivers though that's not 
the best solution unless those cards give you a feature you can't get with 
run of the mill Symbios/LSI-based SCSI cards.

The system handbook section on Sun-supported SCSI cards is at:

ttp://www.sunshack.org/data/sh/2.1/infoserver.central/data/syshbk/Devices/SCSI/SCSI_TOC.html

Check the PCI section. Lots more than those will work, but grab a 
Sun-barcoded card if you want to be sure.
