Connecting Dell Storage to dual servers.

[Kdes]

Hi All

Please forgive me a for a very newbie question.

We have a Dell PowerVault MD3420 with a Single 4G Cache Controller.
This unit is going to be connected to two servers. There will be separate volumes for each server. 1 Volume for server 1. And Volume 2 for server 2.

I see the unit as 4 SAS in ports, and 2 SAS out Ports.
Which SAS HD ports do i connect the servers to, the in our out SAS ports?

eg would it be
SAS Out 1 - Server 1
SAS Out 2 - Server 2

Thank you.
