Detection And Autoconfiguration For Dell Equallogic Arrays; Detection And Port Configuration For Dell Compellent Arrays - Dell Force10 MXL Blade Configuration Manual

Detection and Autoconfiguration for Dell EqualLogic Arrays

The iSCSI optimization feature includes auto-provisioning support with the ability to detect directly
connected Dell EqualLogic storage arrays and automatically reconfigure the switch to enhance storage
traffic flows.
The MXL Switch uses the link layer discovery protocol (LLDP) to discover Dell EqualLogic devices on
the network. LLDP is enabled by default. For more information about LLDP, refer to
Discovery Protocol
The following message is displayed the first time a Dell EqualLogic array is detected and describes the
configuration changes that are automatically performed:
%STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_AUTO_CONFIG: This switch is being configured
for optimal conditions to support iSCSI traffic which will cause some automatic
configuration to occur including jumbo frames and flow-control on all ports; no
storm control and spanning-tree port fast to be enabled on the port of
detection.
The following syslog message is generated the first time an EqualLogic array is detected:
%STKUNIT0-M:CP %LLDP-5-LLDP_EQL_DETECTED: EqualLogic Storage Array detected on
interface Te 1/43
• At the first detection of an EqualLogic array, an MTU of 1200 is enabled on all ports and port-channels
(if it is has not already been enabled).
• Spanning-tree portfast is enabled on the interface identified by LLDP if the port is in L2 mode.
• Unicast storm control is disabled on the interface identified by LLDP.

Detection and Port Configuration for Dell Compellent Arrays

MXL Switches support the
Compellent storage array. The command configures a port for the best iSCSI traffic conditions and must be
entered in INTERFACE Configuration mode.
The following message is displayed the first time you use the
a port connected to a Dell Compellent storage array and describes the configuration changes that are
automatically performed:
%STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_AUTO_CONFIG: This switch is being configured
for optimal conditions to support iSCSI traffic which will cause some automatic
configuration to occur including jumbo frames and flow-control on all ports; no
storm control and spanning-tree port fast to be enabled on the port of
detection.
