<div>
i usually go in order<br />
first 2 disks for raid 1 and so on for raid 5<br />
your next 3 (at a minimum) will make your raid 5; add more for more space<br />
if i were building that configuration i would put 5 disks in the raid 5 and leave that last drive as a global hot spare<br />
<br />
all the drives in each container have to be the same speed and size<br />
if i had 2 300gb drives i would put in the first 2 slots for the raid 1 array and if i had the other 6 as 900gb drives then build as raid 5 then the last one a hot spare that can accommodate a failure in either array<br />
<br />
unless there is some serious i/o need that would benefit from having 2 controllers, usually it is just fine with multiple raid arrays on the same controller

Or you might want to consider including the &quot;spare&quot; in a RAID-6 RAIDset

Or you might want to consider including the "spare" in a RAID-6 RAIDset

I considered RAID 6, but just trying to keep everything consistant. &nbsp;All the other phyical servers are set to RAID 1 &amp;&nbsp;RAID 5. &nbsp;But none are consistant.

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
