Did you really look at the annex for this ? > The TCP port is the 16 bit port portion of > the > ip:port address provided by a ULP that uses the RDMA-CM to > rdma_resolve_addr(), again the annex explained how the port is embedded > into the SID, I don't remember the location within the 64 bit string. It's in the low 16 bits (bytes 6-7) of the SID as the annex indicates. > Or. > > -------- Original Message -------- > Subject: > Re: QoS for iSER > Date: > Mon, 12 Nov 2007 11:41:43 +0200 > From: Yevgeny Kliteynik <[EMAIL PROTECTED]> > > Hi Erez, > > Erez Zilber wrote: > > to create the SID, the rdma cm combines > > > > 1) the port space > > What is the port space for iSER? > For SDP it's 0x10000 - 0x1FFFF. > For RDS it's 0x1060000 - 0x106FFFF > For iSER it's ...? These numbers are too large for just "port space". iSER SID is 0x000000000106035c in your nomenclature, I guess 0x106035c 01 says RDMA aware ULP service ID range 06 says IP protocol is TCP 0x035c (port 860) is the well known TCP port for iSCSI -- Hal > > 2) the rdma cm signature > > Do you mean something iSER-specific, or just the way the cm > builds the service ID out of port space and tcp port? > Can you give an example? > > > 3) the destination tcp port provided to rdma_resolve_addr > > I guess that tcp port is in the lower 4 nibs of the service ID, > similar to SDP.
