Whiteboard
SAN volume QoS, is not supported by the EqualLogic PS series.
Quality of Service (QoS) based on what is traditionally designated as IEEE 802.1p is not currently
supported for use with PS Series SANs. QoS and Class of Service designations must be disabled.
“PS Series arrays are designed to provide I/O as fast as your network can support it. Therefore, using QoS with
iSCSI traffic does not produce expected or desirable results on the SAN. Also, QoS rules can affect how well–
or even whether–replication succeeds between PS Series groups. If you plan to use QoS, Dell recommends
that you use it only on Wide Area Network (WAN) connections, where bandwidth is shared with other
applications and the PS Series array uses it for time-insensitive replication traffic.
Dell recommends against using QoS on the SAN switches for initiator-target communications paths.”
This blue print should be closed.
