New DC Installation partitioning recommendations

[Guest Martin Mullan]

I have bought a new server with 2x disks which i have setup as raid 1 and

created 2 partions on. Partition 1 is for windows 2003 and partition 2 ia for

AD.

Now I know that the partitioning side of things is correct but am i ok with

both of them being on 1 raid disk, should i actually be using 2x seperate

raid 1 disk arrays for each partition?

Martin,

Having two drives on one array gives you some isolation between OS and data

so if, for example, you were to fill drive 2, it would not affect the

operation of the OS.

Having drives on two different arrays gives you performance benefits, as the

two drives can be written at once. This helps in a high performance

environment, where you can put the pagefile, SQL log files, etc onto a

dedicated array.

In my opinion it is a good idea to partition your primary array into two

separate drives, one for the OS and one for data, as it gives you some

isolation and does not waste the current standard disk drives. I don't

personally see much gain from putting the AD database files on another

drive, but I can see that others might. If you can afford it or require it,

a separate mirrored array for logs etc is nice to have!

Hope that helps,
