Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

currently I have 2 servers with Fault Tolerance working with another server with openfiler as a iSCSI server (looks like without that Fault Tolerance does not work). I would like to remove that server and put the openfiler distribution as another Fault Tolerance protected machine. Is this possible? This way i could save one server and also have faster HD access.

Thanks in advance for your help.

Whilst openfiler will work inside a VM perfectly well, and work as an FT VM I think you've got a bit of a dependancy loop there - where is the .vmdk for the FT Openfiler VM going to live? if it's FT it needs to be somewhere central - meaning another Openfiler or similar, thus negating the benefit right?

Let me know if I've misunderstood the situation.

I'm really not sure why the files need to be central. Aren't they duplicated as the whole virtual machine with FT? –  SoMoS Jun 14 '10 at 8:38
    
no, no they're not, they're specifically held centrally so that all that's transmitted over the network is the memory/CPU/IO/registers - otherwise it would flood even a 10Gbps link. –  Chopper3 Jun 14 '10 at 8:58
    
Oh crap :( Then i would not be able to implement that solution ... well, thanks for you help mate. –  SoMoS Jun 14 '10 at 8:59
