Thx, say I have 4x 1Gb/s old-school eth-port machines that want to saturate their capacity at the same time on one of these, should I just buy 4x 10GBase-T SFP+

Thx, say I have 4x 1Gb/s old-school eth-port machines that want to saturate their capacity at the same time on one of these, should I just buy 4x 10GBase-T SFP+ transceivers for it? Edit: Apparently LGS105/LGS108 has 10Gb/s switching capacity allready so I'm good!
