MySQL Cluster Hardware Software and Networking Requirements
One of the strengths of MySQL Cluster is that it can be run on commodity hardware and has no
unusual requirements in this regard, other than for large amounts of RAM, due to the fact that all live
data storage is done in memory. (It is possible to reduce this requirement using Disk Data tables—
see Section 17.5.12, “MySQL Cluster Disk Data Tables”, for more information about these.) Naturally,
multiple and faster CPUs can enhance performance. Memory requirements for other MySQL Cluster
processes are relatively small.
The software requirements for MySQL Cluster are also modest. Host operating systems do not require
any unusual modules, services, applications, or configuration to support MySQL Cluster. For supported
operating systems, a standard installation should be sufficient. The MySQL software requirements
are simple: all that is needed is a production release of MySQL Cluster. It is not strictly necessary to
compile MySQL yourself merely to be able to use MySQL Cluster. We assume that you are using the
binaries appropriate to your platform, available from the MySQL Cluster software downloads page at
http://dev.mysql.com/downloads/cluster/.
For communication between nodes, MySQL Cluster supports TCP/IP networking in any standard
topology, and the minimum expected for each host is a standard 100 Mbps Ethernet card, plus
a switch, hub, or router to provide network connectivity for the cluster as a whole.
