Hardware & Software Requirements

An OnApp installation requires at least two physical machines – one for the Control Panel server, and the other for the compute resource server. You can have as many compute resource servers as you need. You will also need storage for your virtual servers (a data store), and we recommend that you set up a separate server for storing backups and templates.

Storage Hardware Requirements

If you are going to use OnApp Integrated Storage, make sure to meet the following requirements:

Integrated Storage PlatformLocal Storage OnlyEnterprise SAN
  • OnApp Integrated Storage can group together any number of drives across any compute resource. We strongly recommend a minimum of 2 drives per compute resource to enable redundant data store configurations.
  • At least 1 dedicated NIC assigned per compute resource for the storage network (SAN)
  • IGMP snooping must be disabled on storage switch for storage network
  • minimum 1 dedicated partition in each compute resource
  • separate disk from the primary OS drive recommended
  • centralisedBlockStorage SAN (iSCSI, ATA over Ethernet or Fibre Channel) accessible to every compute resource
  • at least 1 dedicated 1GBit/s NIC assigned per compute resource for the SAN
  • multiple NICs bonded or 10GBit/s ethernet recommended
