Hi all I'm a bit confused. Maybe someone can help me. Our IT has two consultans. One for the infrastructure, esp. for the VM ESX. One for the SQL-Server 2008. We are planning to buy a new server for SQL and our SQL-Consultant wants to have separate Disk-Arrays for DB, TempDB, Log and OS. But our ESX-Consultant tells me it is better to just make one Array for everything, because the architecture of the ESX handels it anyway like that (even if you have different Disk-Arrays). I think the SQL-Consultant is right. Because I believe it must be possible to configure the ESX for more then one disk-array ... Can anyone clarify this a bit for me. Thx a lot Reto E.
