Are there any equivalents in openGL to directx index buffers?

assuming you mean for indexing into a vertex array, then yes.
They are used with glDrawElements and glDrawRangeElements and can either be a normal array with values in (GLushort for preference) or placed in a Vertex Buffer Object in index mode (tends to destory performance on older cards for certain)... CyberSlag5k had a post regarding this kinda thing recently
