I've been working with these drives for a few years now, specifically the ioDriveII and the ioScale2. I figured I should probably start taking note of what I'm finding.

fusionio:performance

Conveniently, these cards are very easy to use in windows. I've been using Dell_IO_Management_3.2.15.1699_x64.exe in Windows 7, 10, Server 2012-2019, and it has worked great.

These cards are also very easy to use in ESXi 5.0-6.7u2. Download the zipped vib (scsi-iomemory-vsl-60L-3.2.16.1731-offline_bundle-9738096.zip) and install it manually through the CLI.

  esxcli software vib install -v /tmp/vibname.vib 

Kind of a pain, but this post outlines it well: https://forum.proxmox.com/threads/configuring-fusion-io-sandisk-iodrive-iodrive2-ioscale-and-ioscale2-cards-with-proxmox.54832/

Right now this tops out at Proxmox 5.4. Version 6 is based on Debian 10 and currently the fusionIO drivers won't build on Debian 10. They're working on it.

Kind of the same as above, I haven't really figured it out yet. I dunno.

The drivers do build and work well in CentOS 7. Right now I'm using both an ioDrive2 and an ioScale on kernel 3.10.0-957.27.2.el7.x86_64. You need to get the utilities, source, and docs “from WD”. The linux install docs do a good job explaining how to build it.
