NoteEach node has four 10 GbE ports. Two are used by for internal networkcommunication. The other two ports are used for VMware high availability, DRS,and client network traffic.The switches must have sufficient available network ports to accommodate thefollowing:l Data network 10 GbE switches: Two, 10 GbE ports per node, per switchl Management network switches: One, 1 GbE and one BMC (iDRAC) port pernode.IP addressesNoteThe AMS or discovery server must reside on the same Layer 2 physical network(or VLAN) as the ESXi management Port (Broadcast Domain). The Ethernetbroadcast protocol is used during the initial detection and deployment process.Virtual 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. SVM_MGMT_IP = ScaleIO storage VM management IP address3. BMC_MGMT_IP = BMC (iDRAC) IP address for each nodeAMS server\ProxyIP addressThe IP address used by the AMS server\proxy software to manage theScaleIO Ready Node servers and logical entities(recommended to reside on the same subnet, unless the proxy is used forDiscovery operations)The formula to calculate IP address subnet pool or subnet needs is: N*Node_MGMT_IP+N*SVM_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.Network Architecture and Physical ConnectivityNetwork prerequisites 37
