My home Kubernetes cluster started out on a Core i7-920 with 8 GB of memory.
Upgraded to 16 GB memory
Upgraded to a Core i5-2400S
Upgraded to a Core i7-3770
Upgraded to 32 GB memory
Recently Upgraded to a Core i5-7600K
I think I’ll stay with that for rather long…
I did however add 2 Intel NUCs (gen 6 and gen 8) to the cluster to have a distributed control plane and some distributed storage.
This is a useless comment… This issue has nothing to do with the brand of printer you bought, and everything to do with the settings of your printer and whether the filament is wet. A well tuned Ender will print better than a much more expensive badly configured printe with wet filament. Of course there are printers now that are much easier to get good results with, especially because they come with build in filament dryers, and automatic tuning.
Are these restrictions set out by the ISP or the dorm?
If you don’t do business with the ISP, then you don’t have to agree to and follow their terms.
So as long as the dorms doesn’t have rules against setting up your own WiFi, then you should be well within your rights to purchase an Internet connection from another provider, but since you are likely not allowed to get your own line installed, you are probably restricted to ISPs that provide a service over the cellular network.
Of course using a cellular connection will give you worse latencies for online games, but at least you can have your own WiFi with low latency for your VR.
If you want to be nice, you could then run as much of your Internet network over ethernet as possible, so you congest the air waves as little as possible, possibly only running the VR headset over WiFi, and maybe even only enabling the WiFi radio when you want to play VR. If all your WiFi devices support 5GHz, you might also completely disable your 2.4GHz WiFi, to leave the most congested frequencies alone.
To lower the chance of someone complaining about your WiFi, you should configure it as a “hidden network”, such that it doesn’t broadcast an SSID, and therefore doesn’t show up when people are looking for WiFi networks to connect to.
I really don’t see much benefit to running two clusters.
I’m also running single clusters with multiple ingress controllers both at home and at work.
If you are concerned with blast radius, you should probably first look into setting up Network Policies to ensure that pods can’t talk to things they shouldn’t.
There is of course still the risk of something escaping the container, but the risk is rather low in comparison. There are options out there for hardening the container runtime further.
You might also look into adding things that can monitor the cluster for intrusions or prevent them. Stuff like running CrowdSec on your ingresses, and using Falco to watch for various malicious behaviour.
So as far as I understand, you have
Is that correct?
Why not get the WiFi in the Comcast router disabled, and use your inner network exclusively, such that both WiFi and ethernet devices are on the same network?
That’s what I did with my network, and I even got the ISP to put their modem/router into bridge mode, so it’s completely transparent.
ZFS doesn’t really support mismatched disks. In OP’s case it would behave as if it was 4x 2TB disks, making 4 TB of raw storage unusable, with 1 disk of parity that would yield 6TB of usable storage. In the future the 2x 2TB disks could be swapped with 4 TB disks, and then ZFS would make use of all the storage, yielding 12 TB of usable storage.
BTRFS handles mismatched disks just fine, however it’s RAID5 and RAID6 modes are still partially broken. RAID1 works fine, but results in half the storage being used for parity, so this would again yield a total of 6TB usable with the current disks.
SSD longevity seems to be better than HDDs overall. The limiting factor is how many write cycles the SSD can handle, but in most cases the write endurance is so high that it’s unreachable by most home/NAS systems.
SSDs are however really bad for cold storage, as they will lose the charge stored in their cells if left unpowered too long. When the SSD is powered it will automatically refresh the cells in the background to ensure they don’t lose their charge.
You are correct. And yes that is kinda the whole point of the distilled models.
