Hi Folks,
Does anybody have any idea when 5.1 may come to General Release? I am
particularly interested in MySQL Cluster as I have several databases
(around 50) totalling 26Gb and would like to consider moving to this
version because of the Cluster Disk Data Storage and the fact the
current hardware doesn't have the RAM requirements to hold these
databases.
Robin from MySQL has said Q1 2007. Kai and Max have both mentioned Q4 2006.
I plan to store the data on a SAN and was wondering if anybody had any
experience with this as yet?
I have current thoughts along the lines of
2 x Pentium 4 1Ghz, 1Gb RAM as management nodes
4 x Pentium 4 1Ghz, 1Gb RAM as SQL nodes
2 x Pentium 4 1Ghz (x 8 cpus), 8Gb RAM as data nodes
You will have two copies of the data on those two data nodes. Kai
demonstrated MySQL Cluster on 5.1.11 running four data nodes on his
laptop, which basically allows one to have two copies of data mirrored
over two nodes (see quickly hacked picture). At least with having more
data nodes one had two copies of data you reduce the single point of
failure. Having more data nodes allows you to split up data across
nodes, etc.

The databases are currently running, replicating and serving around 800
queries per second utilising a 100M network.
Thanks
