Page History

here are many factors that determine how many virtual servers you can run. Below you can find specifications for a non-production testing environment, Small Small Production Cloud, Medium Production Cloud and Enterprise Cloud as well the requirements for Integrated Storage.

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 Platform	Local Storage Only	Enterprise 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

Hardware Requirements for HA

High Availability

Hardware requirements

Here you can find the minimum hardware requirements for servers in the High Availability configuration.

Info
Each of the Control Panel nodes in the High Availability configuration must comply with these requirements.

Processor: 2 x 8 Core CPUs, for example, Xeon e5-2640 v3
Memory: 64GB RAM
Disks: 2 x 400GB SSD
RAID Configuration: RAID 1
Network Adapters: Quad port 1Gbp NIC
