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?!?)<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>

<div>Hi everyone:<br>
<br>
</div>
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: <br>
<br>
- The new server has to be the same or if it has the
same RAID controller (HP Smart Array P420i) would be
enough.<br>
</div>
- 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? <br>
<br>
</div>
Has anyone ever happened through this.<br>
<br>
</div>
Sorry the off topic but i dont know where else to ask.<br>
<br>
</div>
Thanks in advance<br>
