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 Mac= hine. 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
