I dont know of the other brands out, But Adaptec has several to choose from, Here are a few.
How many devices do you plan on connecting.
the Adaptec
1940 can support 7 devices scsi2/3
2940xx,2950xx and 29160 can support 7 scsi2/3 single ended or standard devices or 15 scsi3 Ultra or Ultrawide devices.
the Adaptec 3940xx,3950xx and 39160 can support 15 scsi2/3 single ended or standard devices or 30 scsi3 Ultra or Ultrawide devices, these are 2 controlllers per card and do snake 2 irqs.
I always wonder what happens when you have more then 26 drives, what lettters are used.
The xx's are references for standard, Ultra, Ultrawide or Ultra2Wide.
If your looking for ISA cards There is the Adaptec 1505 that can take 7 devices.
If your lucky to find and can afford a multiplexor you can really get up there on devices.
