OverviewTo prepare a server to be part of a ScaleIO Ready Node environment, you are requiredto perform the following steps.1. Ensure that the environment meets the prerequisites.2. Configure the hardware, including the BIOS, BMC (iDRAC) IP address, and ISOinstallation.3. Install the operating system.4. Prepare the physical network connections.5. Configure network ports.6. Configure disks.These steps are described in full in this document.ScaleIO component requirementsComponents and servers in the ScaleIO system must meet the following requirements.ScaleIO cluster componentsList of required ScaleIO servers.l ScaleIO component servers:n 3-node cluster– One Master MDM– One Slave MDM– One Tie Breaker– Minimum of three SDSs (on the same servers as the above components, oron three different servers)– SDCs, up to the maximum allowed (on the same servers as the abovecomponents, or on different servers)n 5-node cluster– One Master MDM– Two Slave MDMs– Two Tie Breakers– Minimum of three SDSs (on the same servers as the above components, oron three different servers)– SDCs, up to the maximum allowed (on the same servers as the abovecomponents, or on different servers)l ScaleIO Gateway server on a separate server, or together with an MDM or SDS.Do not install the Gateway on an SDC server or on an SDS on which RFcache willbe enabled.Introduction12 Hardware Configuration and Operating System Installation Guide - ESXi Servers
