Maximizing Offload iSCSI Connections
With default driver parameters set, which includes 128 outstanding
commands, bnx2i can offload a maximum of 28 iSCSI connections. This is
not a hard limit, but simple on-chip resource allocation math. The bnx2i
driver can offload > 28 connections by reducing the shared queue size
which, in turn, limits the maximum outstanding tasks on a connection. See
“Setting Values for Optional Properties” on page 74 for information on
sq_size and rq_size. The driver logs the following message to syslog when
the maximum allowed connection offload limit is reached - “bnx2i: unable
to allocate iSCSI context resources.”
