We have 2 servers, same spec. Each server has 2 ssd drives. These servers can be linked through a virtual rack.

I was told it would be best to do this but not sure it looks correct.

Server 1

main website - drive1
mysql data base replicated (from drive 2 on server 2) - drive 2


Server 2

mysql data base master - drive 1

mysql replicated - drive 2


we have a small nas too for backing up the main site and data base daily.


The mysql is growing rather large.

Is this a strange way of doing things?



what is the difference between say mysql replicated, or master and slave say and having the 2 drives in server2 just put in a raid 1 config??

I have no idea really about this kind of thing.



Sorry just to make it clear what i meant in the last part...

on server 2 - why not just put the database on a raid 1 to replicate it. Why has he put DB replicated (slave) for drive 2.

Is not backing up a db the same as replicating it?



I would have thought just do it like this

Server 1 -

main site - drive 1
main site - drive 2

in raid 1


server 2
mysql - drive1
mysql- drive 2

in raid 1

nas storage

mysql backed up and website backed up.
