After checking some blog pages of open solaris, I knew that the old type
drivers of NIC adapter (eg. qe,fqe,ge) was developed by DLPI or GLDv2, but
the bge was developed by GLDv3. I guess sun trunking only support the former
method.
Sun Trunking is supported by some extensions coded directly into some of
the existing monolithic DLPI drivers, such as ge or qfe. The approach has
significant flexibility issues (e.g., you can't trunk across different
drives), and thus we have moved away from it.
Sun does provide a solution: migrate the platform to solaris 10 and use the
built-in command dladm to realize the 802.3 link aggregation support. It's
no sense to me, there are too many 3-party applications developed under
solaris 8 in this project, it's impossible to migrate all of them to solaris
10 just because of the link aggregation problem.
If you're stuck on Solaris 8, your options are limited. There are many
reasons besides built-in link aggregation to move to Solaris 10, though.
We also take our binary compatibility guarantee seriously, and would also
be interested in knowing what problems you encounter with third-party
software. If it is a matter of vendor support, we would also like to know
what key products you need are not supported on Solaris 10.
Any one knows which 3-party software can provide this kind of function:
I'm not aware of one. However, I'd think you could get some Sun GigaSwift
Ethernet (ce) cards, and use Sun Trunking to aggregate them.
realize 802.3 support under solaris 8 by GLDv3 method, otherwise I have to
study the solaris 10 code for link aggregation and port them to sol 8.
I think that would be extremely difficult -- and you would of course end
up with a completely unsupported solution.
