It really depends upon how clever you want to be. If I were to do it, I would push two versions into Solr, one with MB or GB in, for display, and another, resolved to a number, for faceting and querying. I.e do the work outside Solr.
If you did want to be clever, you could use a KeywordTokenizer in an analysis chain (it spits out just a single token) and then write your own UnitResolvingFilterFactory, which you could configure with mapping so such as KB->1024, and spits out integer or float fields. This should then work for querying, as querystring terms would be analysed. It would be neat because the stored.field values would include the pretty units, whilst the indexed values would be pure numbers. You could use the field for range faceting, but you would get the indexed value, I.e. Without the units, as faceting uses the indexed value not the stored one.
