Display of structured directed graphs?
I manage a few global ERP systems. I constantly get requests to display things like our supply chain graphically. Essentially the data is a directed graph, e.g., make A at plant X, ship a to Y, process A to B at Y ... etc. All the libraries I've seen make it quite simple to do a force directed graph depicting this, but what if you want to structure the nodes, e.g., vertically align steps based...

Thanks. Yeah, I left it a little vague as to not sway any opinions. I definitely want at least minimal redundancy on both arrays just to ease the hassle of recovering from a disk failure. I guess I'm really trying to decide if hardware RAID is the way to go, or if letting a fast disk controller hand off the work to software (e.g., zfs) is a better option.
Anyway, I'm just curious to hear what others are doing especially given all the "RAID is dying" talk that's popped up in the last few years.

The zfs question is one I'm debating. I actually already use FreeNAS on the backup server and it seems to be doing well. For the primary server I want an OS I can do more with on, so I'd probably throw something like CentOS on it and then run VMs for specific tasks or to use more bleeding edge distributions. I suppose I could try zfs in Linux.
How Do You Approach Multi-Disk Arrays?
Every 4-5 years I upgrade my home server. This year I've shifted to some nice rack-mounted hardware. At the core of my setup, I have two servers with 8 HDD bays each. One is the active box, and the other is local redundant storage (i.e., backup). Assuming 1 HDD is the system disk, how would you configure the other 7 HDDs to give you 1 massive storage volume in your favorite OS? Would you use...
