This topic describes connectivity architecture, cabling best practice information, and
cable connection examples from typical ScaleIO Ready Node configurations in order to
help you plan your network.
Note
If you are not familiar with ScaleIO system architecture, refer to "System
Architecture" in the ScaleIO User Guide or ScaleIO Deployment Guide .
VLANs can be used as long as the Broadcast Domain is the same between the AMS/
Discovery Server and the ESXi Management port. The best way to use VLANs with
ScaleIO Ready Node is to configure the switch port to Mode Access, and assign it to
one VLAN. A management switch which has only one use is recommended. Usually,
this implies one IP subnet, but the switch can contain several subnets on a single
VLAN.
The use of several VLANs on the same port requires the port to be configured as
Trunk, and the assignment of a VLAN ID on each vSwitch on the ESXi. This
configuration can be performed on a ScaleIO Ready Node after deployment has
finished, by updating the VM network and relevant VMKernel port to use the VLAN ID
set by the switch manager. This is similar to any other VLAN implementation, and it
must be done after deployment because the AMS deployment flow creates and
configures the vSwitches and vmnics as part of the deployment flow.
Note
ScaleIO uses APIPA IP addresses (169.254.x.x/16) for Broadcast and Unicast, and this
requires special configuration during deployment.
It is mandatory to set the Management VLAN as either a Layer 2 VLAN without an IP
address, or as VLAN 0 (meaning, no VLAN). This will facilitate a seamless onsite "Add
Node" operation.
Ensure that you have the following network resources and equipment available before
installing ScaleIO Ready Node servers.
Note
In addition to the requirements below for connecting ScaleIO Ready Node servers to
one or more switches, ensure that you have prepared the items described in
Prerequisites on page 14 .
Switches
One 10 GbE switch is required. Two or more 10 GbE switches may be used for
high availability and load balancing purposes. Separate (one or more) 1 GbE
switches may be used for the management network.
Before you begin connecting the switches, ensure that they are installed and
configured. Do not connect the switches to your organization's network until all
installation and configuration activities are complete.
