MySQL Cluster is a high-availability, high-redundancy version of MySQL adapted for the distributed computing environment. It uses the NDB Cluster storage engine to enable running several MySQL servers in a cluster. This storage engine is available in MySQL 5.1 binary releases and in RPMs compatible with most modern Linux distributions.
MySQL Cluster is currently available and supported on the following platforms:

Linux: x86, AMD64, EMT64, s/390, PPC, Alpha, SPARC, UltraSparc

Solaris: SPARC, UltraSparc, x86, AMD64, EMT64

BSD (FreeBSD, NetBSD, OpenBSD): x86, AMD64, EMT64, PPC

Mac OS X: PPC

HP-UX: PA-RISC

Tru64: Alpha

OpenVMS: Alpha

IRIX: MIPS

Novell Netware: x86

QNX Neutrino: x86

SCO OpenServer, OpenUnix, UnixWare: x86

For exact levels of support available for MySQL Cluster on specific combinations of operating system versions, operating system distributions, and hardware platforms, please refer to the
Cluster Supported Platforms list
maintained by the MySQL Support Team on the MySQL AB website.
MySQL Cluster is not currently supported on Microsoft Windows. We are working to make Cluster available on all operating systems supported by MySQL, including Windows, and will update the information provided here as this work continues.
This chapter represents a work in progress, and its contents are subject to revision as MySQL Cluster continues to evolve. Additional information regarding MySQL Cluster can be found on the MySQL AB Web site at
