Mapping volumes to an ESXi server
27 Dell EMC SC Series: Best Practices with VMware vSphere | 2060-M-BP-V
6.7 iSCSI port multi-VLAN configuration recommendations
For SC Series systems with iSCSI capabilities, SCOS 6.5 and later has multiple-VLAN support for diverse
network configurations and multitenant environments. This multi-VLAN support allows iSCSI storage I/O to be
separated between vSwitches for customers using software iSCSI initiators within the guest. It also allows
admins to isolate specific ESXi host-cluster VMkernel ports to their own dedicated iSCSI storage VLAN.
VLANs assigned to vSwitches isolating in-guest iSCSI initiator traffic for customers
Since iSCSI traffic is not encrypted in its plain form, it is a best practice to isolate that traffic for security
purposes. A common misconception is that CHAP encrypts iSCSI traffic, but it only provides authentication for
the connection to prevent unauthorized access.
Note: In older versions of DSM, the configuration of iSCSI VLANs is functionality that can only be configured
through the traditional Dell Storage Manager Client.
