No. DLMP is just link failover, it is not aggregation. In DLMP only one physical link is in use at any time -- other links are standby. DLMP operates at layer 2. IPMP is similar, but operates at layer 3 (IP) and can be configured to do outbound load spreading. > > What we want, is to have CIFS to be accessible on the lan through the 4 phys > cards, with two double paths > over the 2 switches. > If possible, the 2 double paths should work as 4 paths when everything is ok, > and not just 2 alternative > paths in failover mode. This is not possible to do this using DLMP or IPMP and have all 4 paths carrying load. The only way to do that is to have a 4-way aggregation across both switches (with or without IPMP) and choose the best load balancing policy to spread the workload across multiple clients. -- richard > > > > Da: Richard Elling <[email protected]> > A: [email protected] Gabriele Bulfon <[email protected]> > Data: 26 maggio 2014 21.51.02 CEST > Oggetto: Re: [discuss] DLMP aggr > > > > On May 26, 2014, at 8:54 AM, Gabriele Bulfon via illumos-discuss > <[email protected]> wrote: > >> Hi, is dlmp aggregation already working on any illumos? > > no > >> I just find SmartOS as a possible candidate...am I wrong? > > no > >> Looks like Oracle 11 has "-m haonly" to create dlmp, but this switch is not >> present in illumos dladm. > > you are correct > >> >> In case it is not, will ipmp over two LACP-trunked aggrs over two differnet >> switch work? > > Yes, but to get the equivalent of DLMP, don't use aggrs. > -- richard > > -- > > [email protected] > +1-760-896-4422 > > > ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
