Best practice for Server disk setup

Hi,

I've just bought a dl3808 g6 with four 120GB drives. I have a few questions:

1) What is the optimum/redundant physical positions for me to place the hard drives. Is there a doc that describes this?

2) With a test run I placed them in random bays and when I run smartstart and ran the array configuration utility and saw that two drives were in "Internal Drive Cage at Port 1l: Box 1" and the other two were in "Internal Drive Cage at Port 2l: Box 1". Which drives should I select for two arrays? the two in the same cage, or one drive from each cage i.e create two raid 1 arrays.

Your thoughts are appreciated.

Thanks
Dan

Re: Best practice for Server disk setup

The 380G6 comes with the P410 SAS controller which has 8 i/o ports. if you use it with the first disk cage (no port expanders), there is one link to each each disk slot in the cage. It does not matter where you place the drives or how you combine them into arrays.

Now why did you buy SATA disks for a rather fast SAS controller within a rather powerful server? 3G or 6G SAS they are still running at 7200RPM aren't they?

Thanks for the response.

Any thoughts on questions 2).

Silly me bought the wrong drives. I'm going to upgrade after a while. Stuck with them for now.

Do you have a port expander option that accesses the second disk cage? i.e. can you put disks in all 16 disk slots?

Re: Best practice for Server disk setup

Go for raid 10 for best speed and redundancy.
I have one server using raid 5 with sata disks and the bloody thing is so slow! (But that's on a p200 controller, could be bettor on a P410 controller)
