@JasGot Are these media files images or videos? For images, they can look into something like the Smush Pro plugin (provided they're using WordPress CMS), videos can be easily hosted elsewhere like on YouTube or Vimeo and simply embedded to the website instead. Or they're talking about excess traffic caused by this activity?

Try iPerf. It definitely puts storage out of the equation. Try using it with parallel threads to get more accurate results what the link can really handle. Also, it would only test TCP throughput by default but you can test UDP on a client side with -u switch. There are tons of guides on it online.

@Dashrender said in How much RAM for this VM?:

why does the consumed have those dips?

I'd say this was invoked by the apps running on it. This VM is used for analytics and reporting, it's got Visual Studio, Power Bi and SQL server running on it. The vendor must've been doing some shit on it.

Do they have a vCenter running that controls that host? You can run some useful charts there that tells you how it was utilised over a certain time. I have one of VMs set up as per its vendor's requirements with 24 GB of RAM and I can't touch it otherwise they won't support it. This is how much this production VM has used its allocated memory over a year:)

@scottalanmiller I can remove the card for sure, but its not a practical lab exercise for what I'm working on.

I would do this in my personal lab possibly to do that, but not here, in this lab.

You can just the change the controller to HBA mode. In HBA mode it will work like a HBA.
On older cards you have to flash the firmware, on newer cards it's often just a setting.
From a hardware perspective a RAID card is a HBA + more powerful hardware for parity calcs + larger memory cache.

Hang on a sec see if I'll find the link on how to do it.

A newer way to set HP controller to HBA mode:

This is a older longer way to do it:

I was just about to reply to turn passthrough mode (HBA) on on the controller but you nailed it! On the other hand, Proxmox works fine with hardware RAID. As a matter of fact, this is what the vendor themselves recommend: https://pve.proxmox.com/wiki/Raid_controller. Software ZFS RAID can potentially be faster but it needs to be configured properly with direct access to disks, plenty of RAM and ZIL for caching.

Are you positive no logical volume is configured on that host in its RAID controller? You should be able to check it via iLO. Or you can start Provmox VE installer in debug mode that gives you a console. You can use it to list all recognised drives.

Proxmox would not offer any mdraid configuration in its installer. https://pve.proxmox.com/wiki/Software_RAID

Asset Tiger is pretty good in my experience. Hosted and free for 250 assets or less.

@Pete-S I'd stay away from the 7xx Intel NICs, I heard lots of bad things on different IT forums how they play up. The Mellanox NICs would be my first choice for anything with RDMA support.

@biggen NVMe storage is indeed ridiculously fast. When I say fast think about its latency rather than throughput. In practice, their performance really shines with heavily used relational DBs. Doing RAID over the network with NVMe would require at least 25 GbE with RDMA support end-to-end and would work even better with NVMeoF initiator. Otherwise, network latency would be a bottleneck. However, for 4k video editing, 10 GbE end-to-end with SSD storage on the server should be sufficient.

There is a better alternative than interface bonding between a single file server and clients, it's called SMB multi-channel support that uses multiple network interfaces for data transfers (clients need to have multiple NICs though). This way network bandwidth is aggregated with active-active paths not load balanced with active-passive. The downside is SMB Multichannel works reliably in all Windows environment, its Samba implementation is patchy. Mac OS doesn't support it at all AFAIK.
