Hi,

what is the exact syntax to enable large transfer sizes?
I didn't find any documentation, so I guessed the following:
etc/system: set maxphys=8338608
/kernel/drv/sd.conf: name="sd" parent="scsi"
        sd_max_xfer_size=0x800000;
/kernel/drv/ssd.conf: name="ssd" parent="scsi_vhci" sd_max_xfer_size=0x800000;
(I have FC drives)

Where can I teach myself about the disadvantages? I searched for an article or 
paper about "Why 128k blocksize is enough" written by the ZFS designer, but 
could not find it...

Thx in advance, Paul
