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
