<div dir="ltr">My immediate thought is that without RAID, a disk failure means that if a disk fails, you will have to manually take a HAMMER slave PFS and change it to a master, which should be possible - but will take time. RAID will (usually, hopefully) handle a single disk failure without interruption. <div>

Greetings all.<br>
<br>
I'm wondering what the best practice is for setting up a network mass storage box using HAMMER, assuming you can start from scratch and completely control every aspect of the hardware?<br>
<br>
Specifically (but general ideas are also welcome), I've used the 3ware (is it LSI now?) hardware RAID controllers for some time, but is hardware RAID necessary with HAMMER's ability to mirror? Would it be better to just get a 4 port SATA controller and let HAMMER mirror the important bits?<br>
<br>
Thanks in advance! :D<span class="HOEnZb"><font color="#888888"><br>
