PCIe SSD experiences with Proxmox

[e100]

I am looking to purchase some PCIe SSD for a few servers.

Has anyone had any experiences, positive or negative with PCIe SSd cards?
Suggestions for make/model that works well with Proxmox?

For the proxmox team, this seems like a simple patch that should be included to enable easy usage of the OCZ PCie drives:
https://github.com/proxmox/pve-kernel-2.6.32/issues/1
Any plans to include this?


The latest Intel cards require a custom driver and its only developed against 3.10 mainline.
Any chance this driver could be included in the Proxmox RHEL 7 kernel when its released?

Include what? The link to the patch does not work for me.

But yes, we can include such things - fasted way would be if you provide patches.

Apparently the person who submitted that issue on github left out a link to the repo that contains the diff:

I am leaning towards purchasing a Micron P420m which is supported by the mtip32xx driver already included in the upstream kernel.
According to one review the P420m will do 100k IOPS Write, 580kIOPS Read in CentOS.

In hopes that this might help someone else....

I ended up getting a couple of Micron p420m PCIe SSDs.
The driver included in the Proxmox 2.6.32 and 3.10 kernels was very outdated and unreliable.

Downloaded the latest support pack:
http://www.micron.com/~/media/documents/products/software/b145,-d-,03,-d-,00_linux_vmware.gz

Installed the ubuntu dkms package (mtip32xx-dkms_3.8.1-0ubuntu1_all.deb), updated driver installs and works well on 3.10. I did not try it on 2.6.32.

The Real SSD Manager cli application included in the support pack also installs and works well.
