Hello,

i have searched informations about geom-gate and RAID1 or
Raid10 over TCP/IP. But nothing relevant found, so that i write
the questions here.

My opinion/scenario that i thinked out:
i Have 2 Machines Host  A and Host B,
both Machines have 2 Networkinterfaces,
one official and one private.
The official interfaces getting bound with CARP for
traffic, so that peoples think they connect's to one Machine.
So that i get, for this case, a high-availibility-solution on CARP-Base.
The private interfaces get to be used to derive my data from one Machine
to the other Machine, and also spend the possibility to watch the other Machine.

To this point everything is clear for me, so let us go to the more
complex part.

In the description above i be suppressed to derive the shared-data
for booth machines from one to another. My idea was to build an
RAID1 or RAID10 over the Network by using geom-gate and vinum
respective gvinum.

Has anyone any experiences with geom-gate and doing RAID1 or RAID10 over
TCP/IP? And has anyone a good solution in Production use?
My Questions about these thema are:
a) Is this generally possible with FreeBSD ?
b)is this generally a good idea ?
c)how must i setup the RAID?
d)who must build the raid? Host A? Host B? or BOTH?
e) can i use this way to become an HA-Solution?

I have searched in the Web about these questions, but nothing found.
Only things that i have found was Mirroring (local) and mode generals
related to local work with geom.

Thanks for help.

regards

Michael
