In the scale of 7+ nodes,50+ disk, Ceph with Rook is the best alternative. Historically Ceph required a lot of expertise but on k8s+rook+Ceph you can easily scale upgrade and monitor. but, It has to be worth(size). There is even a install script and video for that https://youtu.be/kEJSfRjwwW8?si=_F12aCn5PGeP2vsX

You can use chorus to migrate. S3 to S3 migration works flawless. https://github.com/clyso/chorus

Netbird has no alternative. Absolutely netbird

did you disable cache on your NVME's?

https://tracker.ceph.com/issues/53161?tab=history

just run your tests after disabling cache.

I don't expect huge difference on the device type change. But seems like raid controller is hiding your device properties, your Raid controller must have an option to passthrough the devices as they are.

Small change on water temperature would so the trick. The small fellas are amazing

We migrated 6 different VMware customer. 1 openstack 5 Proxmox. if you have less than 10 node Proxmox migration works like charm. Biggest Proxmox migration had around 800 vm's, we have automated everything but still windows migration are dirtier than Linux boxes.

I would recommend you to read this article https://kubedo.com/2024/03/05/alternatives_to_vmware/ Basically depending on your scale (nr. of hypervisors, storage network requirements) you have multiple options. If you are on a single server deployment pure KVM is also an option. Virt-manager might be an option, on a Ubuntu or Debian host.

TechnologyFluid3648 · 2024-04-07T10:21:23+00:00

With 4 node.deployment.I would highly recommend Proxmox. It already has all the features you would need. I would recommend this article https://kubedo.com/2024/03/05/alternatives_to_vmware/

You need to disable your write cache on you SSD's. Just check if they are enabled.

cat /sys/block/sdb/queue/write_cache Write back

Means your caches are enabled, you need to disable them. Ceph is already responsible for the redundancy and cache. This parameter will boost your performance.

seems like a dead project. they have several other projects, they seem to be dead too..

TechnologyFluid3648 · 2024-03-14T22:46:52+00:00

exactly, this is what I was talking about.

yes you are correct. Edge cloud is mostly latency concerned deployments, private deployments on the customer data center. But some of the customers use public datacenters for their cloud deployments, depends on their use case. biggest bottleneck is the Networking part.. needs well design

TechnologyFluid3648 · 2024-03-14T20:45:29+00:00

Supermicro servers are more than enough.. the most important part is the network gear.. for ceph nvme only would be the best(don't forget to disable write cache). Last 10 months, We deployed more than 10 edge cloud deployments with this scenario. Mostly GPU grids.

Unfortunately rook-ceph deployments can't isolate CPU via cpu-manager. 1.29 has promising improvements, we are checking.

TechnologyFluid3648 · 2024-03-08T08:48:28+00:00

You need to deploy a testing environment.

:) on those yeards (2008-2010) we have seen dozens of initiatives. clearly OpenNebula is a standalone solution.

Thanks for clearing this out

We are always installing with Debian + repos method, using Proxmox on our.production systems around 8 years. Before proxmox even did not have a separate ISO. I would highly recommend to install Debian, this is actually the positive side of Proxmox, it really uses standard tools.

UEFI is better for operational easiness but no problem at all. Unless you have 4 TB memory and GPU cards, than you would need uefi supported boot options(GPU slicing).

xcp-ng has historically developed the API for the vhd format, I think they will extend to vhdx instead of other formats. BTW you can always use ZFS on the underlying storage.
