46 watts.. but, yea, I expected lower.
But, suppose when its spinning 4x seagate exos, they like their juice.
It apparently doesn't allow HDD hibernation while containers are running, and doesn't appear to like to use any sleep states.

Key word, is idle.
Synology... and HDD hibernation don't really go together very well. If you have containers running, it won't let the HDDs hibernate at all. And- I have a minio instance running.

I wouldn't vote for Hillary period for many reasons. Her sex is not one of them.
A random fact, I actually did vote for a woman to be president. But, it damn sure was not Hillary. There is too much stink associated with her. Too much shit swept under the rug.

I'd say, you have a small instance.
I used to host lemmyonline.com, which has somewhere around 50-100 users.
It was upwards of 50-80g of disk space, and it used a pretty good chunk of bandwidth. CPU/Memory requirements were not very high though.

I'm gonna wait a few years, until prices go waaay down.... and I plan on doubling/tripling the PV capacity, which will make everything much more effective, as well.
xtremeownage Now • 100%
How did you get that rate? We pay 33 cents, and it was 24 cents just a few months ago… wouldn’t be surprised if it goes up again next year and the year after since even 33 cents is government subsidised (so - there’s no cheaper option available).
All about location. There are supposedly many in my area on a different coop utility, who are only paying 0.03c/kwh.
Ooof. Why’d you do that? We simply put (a bit over) 5kW of panels on the roof, and a good 5kW inverter. One day of sun generates about as much power as we use in a week, and even if it’s overcast we still come out ahead.
I had a few other goals I wanted to accomplish-
-
Reliability. The grid here isn't the most stable, and blinks a few times per week. And, a time or two per year, we have an outage. This solution has handled this fantastically well, so well, that I don't even notice when the grid has dropped unless I specifically go for it.
-
Apart of this, was bringing some of my wiring/electrical up to code. This accounted for 10k of the price-tag... I relocated/replaced the mains panel across the house to a location more suitable then my daughter's closet. Also- the panel itself, was pretty old, and needed to be modernized.
One more issue- my PV is undersized a bit. Adding another 3kw, would yield much better returns for me.
Its undersized, because if I oversized it, and sent more energy than I consumed, my lovely utility slaps on a 42$ fee.... which is no-bueno.

If the ROI => 25 years, then it's not worth it- because the hardware and equipment is considered deprecated at that point.
If it lasts 30 years, sure, its making good use of itself. But- everything is rated between 15-25 years. As such, after that period, it's considered end of life, and no longer supported.
Now- I will note, it is not worth it for the "Rate I currently pay", which is 0.08c/kwh. If next year, my electricity rates tripled, it would vastly reduce the amount of time until this solution reached ROI. And- I am betting that electricity does not get cheaper in the future, otherwise I would have not have pulled the trigger on a 50,000$ project, where the math told me it wasn't the best idea.
Also, if you really want to see everything quantified- I plan on publishing all of the math, and numbers at the one year mark... which will be around march. -> https://static.xtremeownage.com/pages/Projects/Solar-Project/

This platform* is getting overrun by trolls and tankies. I’m going back to Reddit

Coming from someone who owns them-
Nah, it's not worth it.... at least, if you strictly look at "saving money" overall.
ROI is on average 10-25 years, depending on your current cost of energy. The components/inverters/etc, are usually rated for 20-25 years.
At least- this applies if you have a properly licensed contractor install everything. If you do everything yourself, its extremely worth it, and would achieve ROI in a decade or less.

What will realistically happen?
Nothing. Companies will just spend a hair more money finding ways to circumvent the new taxes. And, if the new taxes were not easily circumvented- they would just relocate the company to another country with lower taxes.
In the end, the consumer is paying the taxes, and not the company itself, either way.
As promised, if I brought the instance offline, I would give you a heads up in advance. Here are the reasons for me coming to this decision- ## Moderation / Administration Lemmy has absolutely ZERO administration tools, other then the ability to create a report. This, makes it extremely difficult to properly administer anything. As well, other then running reports and queries against the local database manually, I literally do not have insight into anything. I can't even see a list of which users are registered on this instance, without running a query on the database. ## Personal Liability I host lemmyonline.com on some of my personal infrastructure. It shares servers, storage, etc. It is powered via my home solar setup, and actually doesn't cost much to keep online. However- for a project which compensates me exactly $0.00 USD (No- I still don't take donations). It is NOT worth the additional liability I am taking on. That liability being- currently trolls/attackers are literally uploading child-porn to lemmy. Thumbnails and content gets synced to this instance. At that point, I am on the hook for this content. This, also goes back to the problem of literally having basically no moderation capabilities either. Once something is posted, it is sent everywhere. Here in the US, they like to send no-knock raids out. That is no-bueno. ## Project Inefficiencies One issue I have noticed, every single image/thumbnail, appears to get cached by pictrs. This data is never cleaned up, never purged.... so, it will just keep growing, and growing. The growth, isn't drastic, around 10-30G of new data per week- however, this growth isn't going to be sustainable, especially due to again- this project compensates me nothing. While- hosting 100G of content, isn't going to be a problem. When we start looking 1T, 10T, etc.... That costs money. Its not as simple as tossing another disk into my cluster. The storage needs redundancy. So, you need multiple disks there. Then, you need backups. A few more disks here. Then, we need offsite backups. These cost $/TB stored. I don't mind hosting putting some resources up front to host something that takes a nominal amount of resources. However- based on my stats, its going to continue to grow forever as there is no purge/timeout/lifespan attached to these objects. ## I don't enjoy lemmy enough to want to put up with the above headaches. Lets face it. You have already seen me complain about the general negativity around lemmy. The quality of content here, just isn't the same. I have posted lots of interesting content to try and get collaboration going. But, it just doesn't happen. I just don't see nearly as much interesting content, as I want to interact with. ### Summary- I get no benefit from hosting lemmy online. It was a fun side project for a while. I refuse to attempt to monetize it as well. As such, since I don't enjoy it, and the process of keeping on top of the latest attacks for the week is time consuming, and boresome, The plan is simple. The servers will go offline 2023-09-04. ### If you wish to migrate your account to another instance- Here is a tool recently released. https://github.com/gusVLZ/lemmy_handshake
A heads up.... Since, attackers/etc are now uploading CSAM (child porn....) to lemmy, which gets federated to other instances.... Because I really don't want any reason for the feds to come knocking on my door, as of this time, pictrs is now disabled. This means.... if you try to post an image, it will fail. As well, you will notice other issues potentially. Driver for this: https://lemmyonline.com/post/454050 This- is a hobby for me. Given the complete and utter lack of moderation tools to help me properly filter content, the nuclear approach is the only approach here.

I am just wondering... is it me- or is there a LOT of just general negativity here. Every other post I see is... 1. America is bad. 2. Capitalism is bad. Socialism/Communism is good. 3. If you don't like communism, you are a fascist nazi. Honestly, it's kind of killing my mood with Lemmy. There are a few decent communities/subs here, but, the quality of content appears to be falling. I mean, FFS. It can't just be me that is noticing this. It honestly feels like I am supporting a communist platform here.  I am on social media to post and read about things related to technology, automation, race cars, etc. Every other technology post, is somebody bashing on Elon Musk (actually- that is deserved), or talking about Reddit (Let it go. Seriously. We are here, it is there). On my hobby of liking racecars, I guess, half of the people on lemmy feel it is OK to vandalize a car for being too big.... and car hate culture is pretty big. All of this is really turning off my mood regarding lemmy.
 Knock on wood, I have not used them in quite a while.
My adventures in building out a ceph cluster for proxmox storage. As a random note, my particular instance (lemmyonline.com) is hosted on that particular ceph cluster.

Well... That didn't last long...
I can't say for sure- but, there is a good chance I might have a problem. The main picture attached to this post, is a pair of dual bifurcation cards, each with a pair of Samsung PM963 1T enterprise NVMes. It is going into my r730XD. Which... is getting pretty full. This will fill up the last empty PCIe slots.  But, knock on wood, My r730XD supports bifurcation! LOTS of Bifurcation.  As a result, it now has more HDDs, and NVMes then I can count.  What's the problem you ask? Well. That is just one of the many servers I have laying around here, all completely filled with NVMe and SATA SSDs.... Figured I would share. Seeing a bunch of SSDs is always a pretty sight. And- as of two hours ago, my particular lemmy instance was migrated to these new NVMes completely transparently too.

So, last month, my kubernetes cluster decided to literally eat shit while I was out on a work conference. When I returned, I decided to try something a tad different, by rolling out proxmox to all of my servers. Well, I am a huge fan of hyper-converged, and clustered architectures for my home network / lab, so, I decided to give ceph another try. I have previously used it in the past with relative success with Kubernetes (via rook/ceph), and currently leverage longhorn. ## Cluster Details 1. Kube01 - Optiplex SFF - i7-8700 / 32G DDR4 - 1T Samsung 980 NVMe - 128G KIOXIA NVMe (Boot disk) - 512G Sata SSD - 10G via ConnectX-3 2. Kube02 - R730XD - 2x E5-2697a v4 (32c / 64t) - 256G DDR4 - 128T of spinning disk. - 2x 1T 970 evo - 2x 1T 970 evo plus - A few more NVMes, and Sata - Nvidia Tesla P4 GPU. - 2x Google Coral TPU - 10G intel networking 3. Kube05 - HP z240 - i5-6500 / 28G ram - 2T Samsung 970 Evo plus NVMe - 512G Samsung boot NVMe - 10G via ConnectX-3 4. Kube06 - Optiplex Micro - i7-6700 / 16G DDR4 - Liteon 256G Sata SSD (boot) - 1T Samsung 980 ## Attempt number one. I installed and configured ceph, using Kube01, and Kube05. I used a mixture of 5x 970 evo / 970 evo plus / 980 NVMe drives, and expected it to work pretty decently. It didn't. The IO was so bad, it was causing my servers to crash. I ended up removing ceph, and using LVM / ZFS for the time being. Here are some benchmarks I found online: https://docs.google.com/spreadsheets/d/1E9-eXjzsKboiCCX-0u0r5fAjjufLKayaut_FOPxYZjc/edit#gid=0 https://www.proxmox.com/images/download/pve/docs/Proxmox-VE_Ceph-Benchmark-202009-rev2.pdf The TLDR; after lots of research- Don't use consumer SSDs. Only use enterprise SSDs. ## Attempt / Experiment Number 2. I ended up ordering 5x 1T Samsung PM863a enterprise sata drives. After, reinstalling ceph, I put three of the drives into kube05, and one more into kube01 (no ports / power for adding more then a single sata disk...). And- put the cluster together. At first, performance wasn't great.... (but, was still 10x the performance of the first attempt!). But, after updating the crush map to set the failure domain to OSD rather then host, performance picked up quite dramatically. This- is due to the current imbalance of storage/host. Kube05 has 3T of drives, Kube01 has 1T. No storage elsewhere. BUT.... since this was a very successful test, and it was able to deliver enough IOPs to run my I/O heavy kubernetes workloads.... I decided to take it up another step. ### A few notes- Can you guess which drive is the samsung 980 EVO, and which drives are enterprise SATA SSDs? (look at the latency column)  ## Future - Attempt #3 The next goal, is to properly distribute OSDs. Since, I am maxed out on the number of 2.5" SATA drives I can deploy... I picked up some NVMe. 5x 1T Samsung PM963 M.2 NVMe. I picked up a pair of dual-spot half-height bifurcation cards for Kube02. This will allow me to place 4 of these into it, with dedicated bandwidth to the CPU. The remaining one, will be placed inside of Kube01, to replace the 1T samsung 980 NVMe. This should give me a pretty decent distribution of data, and with all enterprise drives, it should deliver pretty acceptable performance. More to come....
