Hi,  flow control can be enabled with no problems.  But, it would only be useful in congested networks, when the Celerra is connected to ports with "shared bandwidth" (i.e. oversubscribed ports).   Gustavo Barreto.
EMC Celerra NS-120 VMware vSphere 4.1  It appears flow control for the Celerra data movers is disabled by default. Best practices for iSCSI and NFS state that flow control should be enabled  Is it a best practice to enable flow control on the Celerra datamovers (txflowctl only) for iSCSI as well as NFS?  I downloaded the Celerra documentation library 6.0 and there's not much content regarding flow control that I could find.  Thank you, Jas
