Minimum Hardware Requirements

To achieve quorum a minimum of three appliances are required. The storage in the appliance can be SAS or SATA HDD or SSDs but a minimum of 1x SSD is required for use as a journal (write log) device in each appliance. Appliances must use a hardware RAID controller for QuantaStor boot/system devices and we recommend using a hardware RAID controller for the storage pools as well.

  • Intel Xeon or AMD Opteron CPU
  • 64 GB RAM
  • 3x QuantaStor storage appliances minimum (up to 64x appliances)
  • 1x write endurance SSD device per appliance to make journal devices from. Have 1x SSD device for each 4x Ceph OSDs.
  • 5x to 100x HDDs or SSD for data storage per appliance
  • 1x hardware RAID controller for OSDs (SAS HBA can also be used but RAID is faster)
