VLAN_F_DB_Cluster

vSwitch#2

Used by SQL DB servers

in the SharePoint farm

VLAN_G_WFE_NLB

vSwitch#3

Used by WFE servers in

the SharePoint farm for

the NLB cluster

communication.

WFE1 and WFE2

The VLAN segregation for the different network types helps isolate the traffic among components of

the SharePoint farm. Also, as an application best practice, all the SharePoint 2010 farm roles on any of

the three Hyper-V cluster hosts communicate using the same virtual switch —vSwitch#1 in this

architecture.

SAN architecture

The SAN includes two PowerConnect 7048 switches that support iSCSI data traffic. The two switches

were connected together with stacking modules in Ethernet mode configured as an inter-switch link

(ISL) Link Aggregation Group (LAG). In addition, the solution supports up to eight 1 GB uplinks from

each switch to link into an existing core iSCSI network infrastructure.

Similar to the LAN traffic, the traffic for the SAN was also segregated into its own VLAN. This facilitates

isolation from the default VLAN and gives a separation between SAN traffic and any other traffic that it

may come across if the SAN is uplinked to a LAN or extended to another SAN for replication.

In this reference architecture, there was only one VLAN created for iSCSI traffic. This includes both the

Hyper-V CSV cluster traffic to the iSCSI storage arrays and all the SharePoint Database access traffic.

A combination of NDC and add-in NIC ports was used for the iSCSI traffic and MPIO along with

EqualLogic Device Specific Module (DSM) is used for load balancing the iSCSI traffic. It also enables

fault tolerance against any physical link failures at either NDC or the add-in NIC.
