[openib-general] RE: [Ips] iSER API's

[Dan Bar Dov]

Eddy hi,

 

OpenIB maintains a WIKI at https://openib.org/tiki/tiki-index.php

However I'm not sure it contains any ib_verbs documentation.

 

I'm CCing the openib mailing list, maybe someone there knows where you
can find documentation.

 

Dan

I assume ib_verbs is for Infiniband. Am I correct?

 

Where can I get the ib_verbs API documentation?

	Indeed on Linux the direction is towards a generic RDMA
interface. CMA provides a generic CM abstraction, and the ib_verbs API
is planned to extend over iWARP one way or another. 

	The DM was deemed unnecessary, the API between iSCSI & SCSI and
the underlying iSER enforced redesign of the iSER API to conform with
iSCSI and SCSI rather then implement yet another layer between iSER and
iSCSI/SCSI (namely DM).

		Eddy,

		What APIs are you asking about?  The SCSI CLASS Driver
to the Device Driver (Mini Port Driver) should have the same interfaces
for iSER as it is available for iSCSI.  If you mean between the Device
Driver (Mini Port Driver) and the RNIC, that will probably be the RNIC
vendors interface if they have implemented all or part of the iSER or
Data Mover in the RNIC itself, or the RNIC vendor's interfaces to their
version of the verbs (at least until the OS implements its own RDMA
interfaces that implement the RDMA verbs). 

		 

		I believe that, over time, most OSs will have generic
RDMA interfaces, which can be use by all certified RNIC hardware, and
any application (user space or kernel space); in that case the iSER
module will probably interface to that OS's RDMA interfaces.

		Is there any work afoot to design some standard iSER
API's?
