Requirements Before Getting Started

  • 3x QuantaStor servers minimum
    • Dual Intel or AMD CPUs
    • 96 GB RAM
    • 2x SSDs in hardware RAID1 (boot/system)
    • 4x or more SSDs/HDDs for OSD data devices per server
    • 2x SSDs per server for Journal Groups (only required for HDD based OSD systems)

Front-end / Back-end Network Configuration

Network configuration for Ceph Clusters may use separate front-end and back-end networks. Depending on the protocols to be used it can sometimes be easier and simpler to configure a given Ceph Cluster with a single subnet for both the front-end/public network and the back-end/cluster network communication. With 100GbE and faster networks it is more common to deploy a single network configured for all cluster traffic.
