Sun internal disks and HBA card

I have a V490 that has couple internal disks attached to the same dual-port HBA card that I'm planning attach to the SAN for additional storage.

Would I sacrifice performance if I use the same HBA?

Is it better to throw in a new HBA instead?

To not suffer disruption you usually use 2 HBA through 2 separate paths...
Your internal drives are HW raid/mirror with spare or software?
If software when disks go wrong usually it sends reset SCSI signals which affect the others diversely...
For safety I would go with 2 new HBAs...

All the best
