IP addressesVirtual IP and AMS features are not supported by ScaleIO Ready Node v2.0, but itis recommended to take the corresponding configurations into account whenplanning your network, to streamline future support for these features. Reservean additional IP address in each Data Network for future use.Prepare IP addresses in your network for the ScaleIO Ready Node servers, basedon the following calculations:Table 3 ScaleIO management IP networkItem DescriptionN Number of nodesIP address pools The pools of IP addresses used for static allocation for the followinggroups:1. Node_MGMT_IP = Management IP addresses of the ScaleIO ReadyNode servers2. BMC_MGMT_IP = BMC (iDRAC) IP address for each nodeThe formula to calculate IP address subnet pool or subnet needs is: N*Node_MGMT_IP+N*BMC_MGMT_IP + Optional (AMS server IP address)NoteEach pool can belong to a single subnet or to several subnets, as long as the AMSserver has routable networking access to the Management IP address.The ScaleIO Data IP network requires 2 separate subnets.Table 4 ScaleIO data IP network for Subnet #1Item Description CommentsN Number of nodesIP addresspool forSubnet #1The pools of IP addresses used for static allocation forthe following groups:1.
