Re: Replacing a Dual Port with Single Port drive
RPM speed is not an issue. Atleast it never was with SCSI. OK you'll lose a bit of speed but it allways worked as long as the disk capacity was high enough.
Some more info about the hardware/setup would be usefull. I assume you are using the P400 raid controller. (But for all I know you could be taking about ZFS Raidz)

SolutionYou can use a single port to replace a dual port, but the array may run into issues.
If you are using the Smart Array P400 controller, single or dual will not matter, the P400 runs in single port mode only, IIRC.
The P410 controller does run dual port mode, but if one drive in the array is SP, the rest of the array may step down to single port mode.
