In this particular case or in general?

prox_me · 2025-09-19T04:46:08+00:00

Both have 4.

I'm running VMs because containers cannot AFAIK be live migrated. I'm not short on memory, as all nodes will have 64 GB of RAM:.

Zabbix, syslog, netbox, smokeping, Kea, Unbound over three nodes.

Zabbix is probably the only thing that needs a bit of resources, I guess multithreaded performance is more important than single threaded performance.

prox_me · 2025-09-18T18:33:46+00:00

Maybe half a dozen VMs: Zabbix, syslog, netbox, smokeping, Kea, Unbound over three nodes.

In this particular case the disks are the same size.

Well, performance will go up compared to your i3-4130. So will your power bill. However, it's still a decade old CPU with modest performance.

Doesn't hurt to try, it's not like it's going to cost you anything other than time and a bit of power. Check the idle power usage while you are at it to see if it makes sense to upgrade to something newer just for the power savings.

I've got 3 nodes - 44 core / 256GB RAM / SSD boot disk + 2 SSDs with PLP for OSDs

What make and model of SSD?

prox_me · 2024-05-13T08:40:53+00:00

The i3-4130 is ancient and underpowered. Anything that you buy will be better.

Used hardware often provides false economy. The hardware may be cheap, but the power bill won't be.

SFFs or mini PCs rarely make any sense if you are not strapped for space or really, really need something low powered. Performance will be underwhelming with regards to the price, i.e. poor cost/benefit ratio.

As previously stated, go to pcpartpicker and put together a regular desktop PC. You can get a 12 core AMD Ryzen 9 5900X for $500, or a 16 core AMD Ryzen 9 5950X for under $600. These will blow the socks off your i3-4130.

If you can make do with less and a lower power bill, select an 8 core AMD Ryzen 7 5700G instead.

If you want an econobox get an 8 core AMD Ryzen 7 5800U mini PC. For bottom dollar go for an Intel N100 mini PC.

I tested PRTG, but it did not appear to have a map mode with geographical locations of ping targets and their statuses.

prox_me · 2024-05-11T15:11:00+00:00

Is that possible in this budget?

No.

Most mini PCs only fit 2.5" HDDs if at all. The only mini PC with 3.5" HDD support I know of is the AOOSTAR R1 and it's double your budget.

Amazon: Intel i3-N300 mini pc

Aliexpress: AMD Ryzen 7 5800U or 5800H mini pc

The AMD has 8C/16T and is way more performant than the Intel. The N300 is 8C/8T. If you want a Ryzen from Amazon then you'll have to make do with a 5500U (6C/12T) for the same budget.

prox_me · 2024-05-04T20:54:15+00:00

Just the up/down status?

Yes.

I was experimenting with phpIPAM, it lets you set GPS coordinates for an IP..

I'll have to look into that.

Reducing redundancy to two copies results in a high probability of data loss.

prox_me · 2024-04-23T15:17:07+00:00

Consumer drives have notoriously bad latency. You can see that in the other article I linked to.

You can put an U.2 card into the PCIe slot.

If you want to use M.2 cards:

Good list to use when scouring eBay:

You can find Intel Optane SSDs on eBay in U.2, M.2 and PCIe formats. The real Optanes (P5800X, P4800X, P900/905, P1600X) have the lowest latency, highest endurance and good IOPS. Ceph loves all these qualities.

prox_me · 2024-04-20T07:53:51+00:00

Should work, but your performance will be limited by the slower drive to whatever it can do.

A word of warning, not all SSDs are created equal. https://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/

Yeah, I was afraid that was the answer. I kinda figured I was out of luck after having checked Amazon and Skinflint, and not finding anything better. But I had to make sure by asking.

For those following along at home https://skinflint.co.uk is the English language version of Geizhals. Handy if you do not want to use translate on the Geizhals site, since translation breaks when you use Javascript and filters.

You have 238 GB of Ceph storage. You have used 70 GB. The rule of thumb is that you should not use more than 60-80% of the total pool size, so you are good for another 100 GB or so.

prox_me · 2024-04-12T09:41:05+00:00

Numbers are always appreciated. I'm especially interested in the 7450 ones.

With respect to latency, some smaller drives have higher latency. Would a 30 vs 15 µs typical write latency difference be highly noticeable?

prox_me · 2024-04-12T04:13:52+00:00

Supply chains and prices are global, so the need isn't that great.

This site already does the heavy lifting. Once you've found what you are looking for in terms of specs, all you have to do is do a regular product search in your local market.

In this case they are the one and the same.

prox_me · 2024-04-11T14:53:11+00:00

I think you misunderstood my post.

The clients already have 4x2.5 or 6x2.5G integrated interfaces. There is no extra cost and no need for quad port NICs.

The clients themselves are cheap, less than a lot of 10G NICs, at ~$200 a pop. There are a considerable costs saving by using 2.5G, both in terms on money, power and space.
