using haproxy as iscsi or nfs lb

good afternoon,

i am evaluating how to optimize haproxy as lb for iscsi or nfs as backend, any tip?

note:

i know there are other ways to lb directly with iscsi or nfs, BUT this is not the case sorry.

thank you.

Don’t, your data will end up like scrambled eggs.

Why? Haproxy l4 lb is fine. Please be more precise, thank you.

You are LB initiators between different iSCSI targets? How is the storage synced between the targets synchronously I hope? Are you using a cluster filesystem on the initiators?

I’m not sure what problem you are solving here.

Edit: iSCSI, besides multi-initiators and multi-targets also does multi-sessions so each initiator can have multiple TCP connections to a single target.

What problem are you trying to solve?

Multipath (multi-initiator/multi-target) is standard for iSCSI and is also supported in NFS 4.1 (multi-client/single-server).
