The following are recommendations, rather than fixed requirements. However, our experience in developing this documentation indicated the following suggestions.
Front End
Use the following table for a system that will run one or more of:
- the cloud controller (clc)
- the cluster controller (cc)
- walrus (the S3-like storage service)
- the storage controller (sc)
| Hardware | Minimum | Suggested | Notes |
| CPU | 1GHz | 2 x 2GHz | for an all-in-one front end, it helps to have at least a dual core processor |
| Memory | 2GB | 4GB | the Java web front end benefits from lots of available memory |
| Disk | 5400rpm IDE | 7200rpm SATA | slower disks will work, but will yield much longer instance startup times |
| Disk Space | 40GB | 200GB | 40GB is only enough space for only a single image, cache, etc., Eucalyptus does not like to run out of disk space |
| Networking | 100Mbps | 1000Mbps | machine images are hundreds of MB, and need to be copied over the network to nodes |
Node(s)
The other system(s) are nodes, which will run:
- the node controller (nc)
These systems will actually run the instances. You will need one or more systems with:
| Hardware | Minimum | Suggested | Notes |
| CPU | VT extensions | VT, 64-bit, Multicore | 64-bit can run both i386, and amd64 instances; by default, Eucalyptus will only run 1 VM per CPU core on a Node |
| Memory | 1GB | 4GB | additional memory means more, and larger guests |
| Disk | 5400rpm IDE | 7200rpm SATA or SCSI | Eucalyptus nodes are disk-intensive; I/O wait will likely be the performance bottleneck |
| Disk Space | 40GB | 100GB | images will be cached locally, Eucalyptus does not like to run out of disk space |
| Networking | 100Mbps | 1000Mbps | machine images are hundreds of MB, and need to be copied over the network to nodes |
