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 200GB or larger high write endurance SSD/NVMe/NVRAM device for the write log / journal (we recommend 4x OSDs per journal device and no more than 8x OSDs per journal device)
- 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)
