How is the best way to attach two Microsoft servers in cluster to a Disk a array? The Disk will contain a SQL Database.

Do i need a SAN Switch for this simple installation?

What hardware elements do i need?

Good article, but i think that i´ve to explain what i need better.
 I´ve read some articles, Fibre Channel, Iscsi, the concept is easy, two servers in cluster, one disk array all connected through a SAN Switch (HBA controllers, wires....).

But, which is the best way (Quality-price)...., I mean, my installation will not grow more, so I don´t have to think on a scalable architecture, I´ve to think in a very small one!!:
 
Is possible to implement it with a Gigabit Switch and a Disk array with gigabit connection? (The servers have two network adapters) The performance would be enough for SQL Database??................. what would i need (hard and soft)? The switch has to be a SAN-Switch or is possible to use a standar Gigabit Ethernet?
Is possible to deploy the above solution using a server with multiple disks instead of the disk array for speed?.

As you can see I need speed but I´m trying to spend as less as possible.

Thanks a lot

Yes, you can use a normal gigabit switch. And a SAN box with iSCSI. In fact, if it will not grow, and you only need two servers, and the SAN offers you two gigabit connections, then you would avoid the switch, you could connect each server to each gigabit interface, although it is not the beast approach, and a gigabit switch is not very expensive.

Option 1) You can purchase a Synology DS1511+, for instance. It is a good and cheap NAS/SAN. You can configure it as SAN through iSCSI. You can purchase your own combination of SATA and SSD disks to fill the box (5 drives).

Option 2) Yes, you could use your own server to offer the local disks through iSCSI. I would not recommend it if they are not hot spare disks. You could take a look to FreeNAS, Nexenta, OpenSolaris (ZFS) as your storage OS.
