To install Eucalyptus, your system must meet the
baseline requirements described in this topic.
The specific requirements of your Eucalyptus
deployment, including the number of
physical machines, structure of the physical network, storage requirements, and access
to software are ultimately determined by the features you choose for your cloud and the
availability of infrastructure required to support those features. See the Compatibility Matrix in the Release Notes for supported versions.
- Physical Machines: All Eucalyptus services must be
installed on physical servers, not virtual machines.
- Central Processing Units (CPUs): We recommend that each host machine in your Eucalyptus cloud contain either an Intel
or AMD processor with a minimum of 4 2GHz cores.
- Operating Systems: Eucalyptus supports the following
Linux distributions: CentOS 7 and RHEL 7. Eucalyptus supports only 64-bit
- Machine Clocks: Each Eucalyptus host machine and any
client machine clocks must be synchronized (for example, using NTP). These
clocks must be synchronized all the time, not only during the installation
- Machine Access: Verify that all machines in your network allow SSH login, and that root or
sudo access is available on each of them.
Storage and Memory Requirements
- Each machine in your network needs a minimum of 160GB of storage.
- We recommend at least 500GB for Walrus and SC hosts running Linux VMs. We recommend at least
250GB for Walrus and SC hosts running Windows VMs.
- We recommend 160GB per NC host running Linux VMs, and at least 250GB per NC host for running
Windows VMs. Note that larger available disk space enables a greater number of
- Each machine in your network needs a minimum of 8GB RAM. However, we recommend more RAM for
- Host machines running multiple services (e.g., CLC, CC and SC) likely need more
than the minimum amounts of RAM and storage.
- All NCs must have access to a minimum of 1Gb Ethernet
- All Eucalyptus components must have at least one
Network Interface Card (NIC) for a base-line deployment. For better network
isolation and scale, the CC should have two NICs (one facing the CLC/user
network and one facing the NC/VM network).
- For EDGE networking mode, Eucalyptus needs at least one existing network.
- For VPCMIDO networking mode, Eucalyptus needs Midokura Enterprise
MidoNet to be installed. For more information, see Install Midokura Enterprise MidoNet.
- The network connecting machines that host Eucalyptus
components (except the CC and NC) must support UDP multicast for IP address
220.127.116.11. Note that UDP multicast is not used over the network that connects
the CC to the NCs. For information about testing connectivity, see Verify Connectivity.
Once you are satisfied that your systems requirements are met,
you are ready to plan your Eucalyptus installation.
