SAN and Internal Networks for iSCSI Appliances

The following prerequisites apply to 10GbE iSCSI appliances. For these appliances, the iSCSI network and internal network share 10GbE ports and switch infrastructure.

■	Prerequisite
□	10GbE switches can be reached from the rack. At least one switch must be available to connect the FluidFS cluster to the Storage Center. An FS8600 appliance cannot be connected directly to a Storage Center. To connect an FS8600 appliance to an SCv2080 storage system, use a switch that supports both 10GBASE-T and SFP+ connectivity. For high availability, deploy two switches (one for each Storage Center fault domain).
□	10GbE switch infrastructure has four LC optical or SFP+ (twinax) connections available for each FS8600 appliance
□	If you are using VLAN tagging, configure one unique VLAN for each iSCSI subnet (Storage Center fault domain).
□	Flow Control is enabled on the switches.
□	Unicast storm control is disabled on the switches.
□	Jumbo frames are enabled on the switches to support a frame size of 9000 bytes. Dell PowerConnect and Force10 switches must be configured to 9216 MTU. Switches from vendors other than Dell might require a different MTU configuration to accept 9000-byte frames.
□	Switches allow multicast between all ports on the iSCSI/internal network.
□	IPv6 is enabled on the switch ports connected to FS8600 appliances. IPv6 link-local addressing is used for internal network communication. Routing of IPv6 traffic is not required on the iSCSI/internal network switches.
□	IGMP and/or MLD snooping are disabled on the switch ports connected to FS8600 appliances.
□	All switch ports connected to FS8600 appliances are set as edge ports or PortFast to skip Spanning Tree negotiation.
