Hi!

Sorry if this look strange to you, it's more or less just my ramblings and hope of getting some help and information :)

Were I work I have one Dell 1850 Poweredge that I use to control a phone system with asterisk, it also control a channel bank (ethernet) and some mysql. Now what I need to do is build redundancy for this server

So far I have
* Network redundancy with bonding two NIC's and using a No point of failure setup
* UPS system to the two redundant PSU's
* Raid 1 system for disk redundancy

Now I have been asked that it would be good to have one more server in case of a crash. I was first going to just get me a new Poweredge 1850 (Simple just transfer the disks and you are back in action), but since they have stop manufacturing 1850 I'll be going for a new server instead.

Using mysql redundancy and stuff I could make this work (sure you still need to go down and move the E1 to the other box but that's about it - Can't afford two E1 lines anyhow) but since the average load is very small I'm wondering what type of server to get I really don't feel I need more power then the 1850 can give me and well even if the company could afford a good server a small price would be nice, so I have even been thinking about simpler workstation computers (because of price and low average load) What do you think about that?

So anyone with experience in running very safe redundant networks on tight budgets? I could really use some input (and yes I know that one would have been do n't buy DELL but it wasn't my decision) I would be very glad for most input and information about running redundancy

Cheers!
