As long as you have a P400-series RAID controller in the server, you
should be fine. Make sure you engage HP tech support prior to putting
the old drives in the new server - one wrong keystroke can destroy all
your data. (And where are your backups?!?)
Having said that, software RAID is substantially more resilient to
*total* hardware failures than hardware RAID - there's no need to match
the specific RAID controller model anymore. On the other hand, hardware
RAID tends to deal with minor failures (i.e. one dead disk) much more
easily and rapidly and effortlessly. YMMV.
The new server being not exactly the same shouldn't be a problem for
Linux (unlike Windows...). If you're doing PCI IO-V, however, it may
matter if you switched processor brands (i.e. AMD vs Intel) as they
require different modules and boot options, but Proxmox should still
boot just without IO-V. If you're using IO-V or USB pass-through, your
device paths may change with the new hardware.
The RAID configuration is stored on each hard drive as well as in the
controller's NVRAM; I recommend resetting the controller to factory
defaults with *no* RAID configuration at all on the new drives, prior to
inserting the old drives. Only insert the old drives while the RAID
controller is (cleanly) powered off, not while it's running! And if at
all possible, again, engage HP support for this kind of disaster
recovery, if you've never tested the procedure before.

Hi everyone:
I am a proxmox enthusiastic user and I have installed on my server HP
Proliant ML350p Gen8, everything was working perfect until a lightning
stroke the server and burn the motherboard. I had proxmox on a RAID 5
(4 x 300 GB hard drives). I just have ordered a new server but the new
one it isn´t exactly alike the old one. My questions are:
- The new server has to be the same or if it has the same RAID
controller (HP Smart Array P420i) would be enough.
- The new server has to come with 4 x 300 GB identical hard drives for
setting them to RAID 5 and then replace with the old ones. Do you
think it will work?
Has anyone ever happened through this.
Sorry the off topic but i dont know where else to ask.
Thanks in advance
