--_004_7AFA66599AC41847AD8E021A1DBB9D1426F9B03EDBpandoreankama_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi guys, I'm really confused about using multiple NICs on my Freebsd initiator to a = Dell Equallogic virtual target (i.e the target has one virtual IP and uses = iSCSI redirections to load balance across the physical NICs of the the targ= et). I'm used to iSCSI initiator on Linux, and on it I can bind my physical inte= rface to iSCSI initiator interfaces and use several initiator interfaces to= the virtual IP, so I get redundant network paths. Then I use dm-multipath = and I get an active/active architecture that performs very well. This is co= ol, but Linux does not have ZFS. With Freebsd, looking in the manuals of iscontrol and iscsi.conf, I can't f= ind a way to use the 2 interfaces of my initiator, because there is no way = to bind one interface to an initiator. I could use 2 instances of iscontrol= pointing to 2 of the real IP of my target, but I would lose all the benefi= ts of using a virtual IP with iSCSI redirections. As my storage is scaling = with more target boxes and NICs, using virtual IP is not really an option i= f I want to keep my path evenly balanced automatically. My goal is to use g= eom_mutipath on top. I've been thinking about using setfib for my second is= control process, have not tested it yet but it looks overkill to me, isn't = it ? BTW, does someone know when the active/active geom_multipath module wi= ll be released as "STABLE" ? I really enjoy Freebsd and ZFS, but it's iSCSI and MPIO layers have surpris= ingly years late looking to other major OS :/ Can I achieve what I want ? Are some progress planned regarding those things ?
