Opposed to 2Gib. One could discuss about M vs. Mi and their friends for quite a while and I think when it comes to Petabytes vs. Pebibytes in terms of capacity there is quite a remarkable difference but in terms of Gbit NIC I don't think of it as important. Also I haven't heard anyone using kibi and the likes before. But I really do not need to discuss about this. However I still don't know why drbd offers the 'G' as suffix although the limit seems to be 700000K....Byte. > I wrote > > >If the unit is meant to be MBytes/s (or MiBytes),... it would mean that > > the base is 2, this gives you speeds of 2^x like 1024 MBytes/s, this > > divided by 8 gives 128M. > > This is just wrong in this case, because the speed of the network link is 1 > Gbit/s so it is 1024 Mbit/s with the base of 2.

So you are using lowercase for powers of 10 and uppercase M for powers of 2 ? Is this official ? Wouldn't it have to be 125mbit/s for drbd instead of 125Mbit ? I'd rather stick to this one: http://physics.nist.gov/cuu/Units/binary.html Haven't seen an iso on this topic so far. By the way- isn't 'ko' used in french for 'kilo octets' ? What would a Gibibyte be in french ? A Gio ? This is getting a bit confusing... If my part of this mail consists of total crap just forget it- now I'm confused ! > > > > _______________________________________________ > drbd-user mailing list > drbd-user at lists.linbit.com > http://lists.linbit.com/mailman/listinfo/drbd-user
