I think you may be obsessing about the "performance" and "cost" aspects entirely too much. 1. What is the makeup of your payload? (number of vms, function, ACTUAL performance in IOPs) 2. a backup device MUST be a separate device then the primary, because, you know, it cant be both primary and...

smh. as you please. I dont and cant provide benchmarks proving a negative. the claim was: without any proof. all I said that this didnt line up with my experience. and your counter is which is not AT ALL an endorsement of the original claim. I didnt claim it did either.

No. I'm saying I saw no benefit using RDMA for SMB. If you are saying you have, it would be good to have repeatable tests to prove- It is entirely possible I didnt have a use case that could benefit. You cant both make a claim and ask someone else to prove/disprove it- you're the only one...

benchmarks please. that has not been my experience. at all.

the relevant questions to ask: 1. Would you want the failover to occur automatically, or with user intervention? 2. What is an acceptable outage period? 3. What is acceptable in terms of minimum performance (specifically, disk performance) IF the acceptable outage period is not too short AND...

swap should be used sparingly if at all on a server device. If you run in a memory constrained environment, you will end up with unpredictable application performance. I dont set up swap on server at all. If I see OOMs I either move VMs or add ram.

the actual media resides on your nas. In order to have jellyfin function you need both jellyfin and the storage present; since your nas can run this function by itself you reduce the required number of devices to one by simply running the application on the storage. The only time it makes sense...

Realize that this creates a two system dependency for your application (jellyfin.) The correct (least dependencies) solution is to have the jellyfin container run on the nas. https://nas.ugreen.com/blogs/how-to/install-jellyfin-setup-step-by-step

graphs dont show any likelihood of networking issues/starvation. if your storage isnt reporting any issues, thats not likely to be your problem.

You havent really established this is a "storage" issue at all. your problem description, suggests the issue is with how your software interacts with the decoding and not so much with the storage; it COULD be the storage but you havent posted any diagnostic data to suggest it, namely- what are...

This is the expected reaction for anyone who hasnt been on the other side of this. REMEMBER, the PRIORITY of any change in systems is, in order: - to provide AT LEAST a minimum of service requirements, as delineated in the RFP. - to cause as little impact to users. lost productivity in the name...

the (much) greater likelihood is that this disk is failing. have you run a smart test? (smarctl --test=long /dev/sda) Assuming the drives are NOT bad, next is to run a full lifecycle upgrade. has the problem gone away? If not, your machine is likely defective- and its probably NOT your perc...

thats a completely normal behavior for windows. It happens to me on a desktop- explorer really likes to cross all the t's and dot all the i's. if you want faster file copy use a different tool (eg, robocopy.) Not sure if that relates to the initial topic, but this behavior is not at all relevant...

I dont believe NFS is an option on an IBM FlashSystem 5200- maybe yours is a different product?

well then, I dont have any useful advice for you. go forth and prosper :)

makes a lot more sense- but still doesnt answer why you want the vps to run proxmox. Also, in this configuration you really want to use shared storage and not local drives. you can still use nvmes with ceph.

because its dumb. YOU might convolute a way to make it make sense; in my world, customers pay me to AVOID complexity. again, the product is the VM.

so the PRODUCT is 20 VMs, not a hypervisor.

Thats... absurd. you're wasting all those resources without any benefit; a cluster is of no value if all resources are HOSTED BY THE SAME DEVICE.

This is how I look at it. You are offering to operate a bus for people. but instead of selling seats, you are putting busses inside your bus. Whats the use case?! If you're trying to offer a customer resources that they can distribute between disparate vms, thats simple enough to do WITHOUT...
