Home server network redundancy
-
Why?
Thats all the reaction I have so far…
-
So there is no easy way to have load balancing with failsafe?
Yes there is, get a switch, NAS and server that supports Link Aggregation (802.3ad), you can bond multiple 1Gig, including failover if links die. You can then run NFS over that bonded link.
This won't protect you from a switch dying, or your internet, or router.
That brings us to redundancy:
It all depends on how redundant you want things, how much performance you need and what you need redundant.
What are the requirements?I haven't seen anything obvious in the configuration of nas4free (my current NAS) that would support that. However, I have not specifically looked for it.
It does, it's what I use.
Why?
Thats all the reaction I have so far…
I just think redundancy at home is a bit silly, especially if you only have one WAN and power source. Regardless, I'm running single WAN, dual firewall with CARP, LAGs between switches/server/NAS, OSFP, multiple VLAN, multiple SSID? Why, because I can :) for practice, fun ;D
BTW, I see some good info/suggestions, but there isn't a lot of info from the OP, so we have to guess a bit at what he wants exactly…

Yeah - At home, I run RAID of RAIDS for data storage. A RAID 0 of RAID 0s for speed and a RAID 1 (that stays offline unless I'm backing up my RAID 0 so some genius can't get in and wipe all my drives+backups). SAMBA for sharing with HTTPS file server and streaming media server for me, friends, family and people I sorta know. All that on a VM on a desktop that is a full time user terminal. So, seriously sparse resources to my file share server… 1GB and 1 core. And yet it has never come close to being strained.
Thats why I wonder about these intricate ubber-blazing resource hungry FreeNAS setups. Using internet to connect to it, it will never see even 5% use.
But, if its just to play with, I can understand.

Yes, average usage will likely be ~5% but I need those 2gbps of burst speed for file copying, moving volumes etc.
I'm doing this for fun and to learn about such setups. If it succeeds, maybe I will move to larger scale, who knows…

What are the requirements?That's the problem. If I want load balancing I don't have any switch redundancy.
If there's no easy way to do this I will go with failsafe instead of performance. I just want to squeeze max out of 1gbps ethernet as 10gbps is quite expensive.
-
again, if you want switch and link redundancy, 2Gbps burst, you can have a look at MCS/MPIO iSCSI, I don't think you can do that with NFS.
but, if you expect actual 2Gbit bursts, that could easily starve other traffic, hence the separate side for the storage network.anyway your setup is possible, there are a lot of things to think about though once you start talking about performance and redundancy.

"Yes there is, get a switch, NAS and server that supports Link Aggregation (802.3ad)"
I got a 24 port one for $30 with 4 additional 1000base-sx optical transceivers on board (-:
If I got it any cheaper I'd need a mask and a pistol…
I suppose I could make a NAS with 4 x gigabit optical connection LACP on my nearly-stolen switch > rest of my network...
But it would idle. Its depressing enough always seeing my pfsense sitting at 0-1% cpu utilization. haha.
But I also do love to tinker. I'll be happy to hear how it turns out.

Or in my case, get them for free, because you work for the people who make them ;-)

I see. - It "Fell off the truck" on the way to delivery…
That makes these little projects so much easier doesn't it?
-
Ehh, they're beta units and for testing (and usually don't want them back) or old lab equipment.
Anyway, sorry OP for the hijack, I hope you got some more info anyway :D
-
I was a bit busy with some irl stuff and getting server hardware but now I'm back again to network.
After hours of googling I found a thing called VRRP. There's not much info about VRRP but I think my setup could be possible with it (?)
Do you guys know anything about that?
I'm already thinking of going without network redundancy. What's the chance that a switch will burn out? In worst case I will replace it in a few hours.

VRRP is CARP.
Well almost. VRRP is the cisco implementation, CARP came a bit later and is the opensource implementation of the same functionality (redundancy). Actually CARP is a bit more since it offers encryption.
