Timer expires on 06/07/2007. -ted ++++ IBTF DDR-QDR Update =================== I. Introduction --------------- PSARC 2002/132 and successor cases defined the InfiniBand Transport Framework (IBTF) interfaces. This fast track proposes enhancements to add new definitions related to new Data Rates (static link rates) introduced in release 1.2. These changes will have a micro/patch binding. II. Description --------------- The new data rates come from new link bundle widths (x8) and DDR (double) and QDR (quad) speeds introduced the 1.2 IB spec. To deal with all these possibilities, ibt_srate_t was changed. With all the new combinations, some rates of data transfer are achievable in multiple ways (e.g. QDR x1 and regular x4). So, we have changed from a description which was based on a link width (x1, x4, x12) to one based on equivalent bandwidth (Gbps). While we have added different descriptions, all new values are a superset of the original set so existing source and compiled code will continue to work. changes (see materials directory): ibti(9) - add reference to the new ibt_srate_t(9S) man page ibt_srate_t(9S) - new man page ibt_aget_paths(9F), ibt_get_alt_path(9F), ibt_get_paths(9F), ibc_adds_vect_t(9S), ibt_adds_vect_t(9S), ibt_alt_path_attr_t(9S), ibt_arej_info_t(9S), ibt_mcg_attr_t(9S), ibt_path_attr_t(9S) - rate values replaced with a reference to ibt_srate_t(9S), plus a "SEE ALSO" for ibt_srate_t(9S) -- Ted H.
