The Guide Tones II voicing of Gb9sus4 stacks Fb and Cb from the bottom up: the minor 7th and 4th of the chord. It leaves out the root, Gb, for the left hand or the bass player to take.
It's one of the Guide Tones voicings: just the 3rd and 7th, the notes that define each chord, played over the root. The other for Gb9sus4 is Guide Tones I.
