It is possible employing Scalable Coherent Interface (SCI) technology to achieve a significant increase in connection speeds and throughput between MySQL Cluster data and SQL nodes. To use SCI, it is necessary to obtain and install Dolphin SCI network cards and to use the drivers and other software supplied by Dolphin. You can get information on obtaining these, from Dolphin Interconnect Solutions. SCI SuperSocket or SCI Transporter support is available for 32-bit and 64-bit Linux, Solaris, Windows, and other platforms. See the Dolphin documentation referenced later in this section for more detailed information regarding platforms supported for SCI.
Prior to MySQL 5.1.20, there were issues with building MySQL
Cluster with SCI support (see Bug #25470), but these have been
resolved due to work contributed by Dolphin. SCI Sockets are
now correctly supported for MySQL Cluster hosts running recent
versions of Linux using the
and versions of MySQL Cluster with SCI Transporter support can
be built using either of
compile-pentium64-max-sci. Both of these
build scripts can be found in the
directory of the MySQL Cluster source trees; it should not be
difficult to adapt them for other platforms. Generally, all
that is necessary is to compile MySQL Cluster with SCI
Transporter support is to configure the MySQL Cluster build
Once you have acquired the required Dolphin hardware and software, you can obtain detailed information on how to adapt a MySQL Cluster configured for normal TCP/IP communication to use SCI from the from the Dolphin SCI online documentation.
