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
  • 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
  • centralised Block Storage 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
