hello all
im looking to setup a new sql server 2012 failover cluster (1 active, 1 passive node for the time being)
im wondering what the best practices are for the data directories, and which disks i should place them on
i originally setup 3 shared disks, 1 for DB, 1 for logs, and 1 for quorum
i believe in sql server 2012 i might need to specify locations for 3 other database locations which are TEMP DB, TEMP LOGS and BACKUP
can the TEMP DB go on the DB disk? and can the TEMP LOGS go on the original LOGS disk?
i assume im going to need to setup another disk for the BACKUP location
also, we are starting this cluster from scratch, and im not 100% sure how big to make each drive- is there a best practice for disk sizes? my department agreed internally that we would create a database drive which is 40gb in size, for the time being- this is being done so we can add more storage later on via our SAN administration console. what should the other sizes of the drives be if this database drive is going to be 80gb?

also, is the MSDTC drive now the QUORUM drive in sql server 2012?
