what is iSCSI initiator session limit ? and is there anyway to exceed this limit ? i'm working on windows server
also in this documentation https://docs.microsoft.com/en-us/windows-server/storage/iscsi/iscsi-target-server-limits ..... what's meant by "Sessions that can simultaneously connect to an iSCSI target instance" .... is that the session that the target can host " or the initiator can start " and what is the difference between forced and not forced

it has never changed.

You have mixed up some questions. Each topic has a limit to answer and solve one issue.


It's implementation specific (usually up to 256) and related to the target as well (target may reject # of the concurrent connections exceeding internal threshold value). Only to make things worse there's also a "multiple connections per session (MC/S)" thing which makes your question even more broad. Clarification question(s): What task are you trying to solve? Is it about increasing performance? Is it just a lab use case? What target are you trying to connect to?
