Dual UPS - Eaton 5130 - fencing solution?

[hotwired007]

I have 2 Eaton 5130 UPS connected to my Proxmox cluster, i have 3 dual PSU servers, each with a connection to both UPS, any recommendations on how to get fencing and HA configured?

I've been looking at ePDUs and switched PDUs like this one:

Has anyone used anything like it for fencing?

i'm using a mixture of Dual PSU Dell servers, (R415/PE1950) so will need a PDU with at least 20 connectors.

Also is it possible to configure proxmox to check two fence devices per host server?

check this http://www.redhat.com/archives/linux-cluster/2011-March/msg00178.html

ahah thanks for that - do you have any recommendations for a suitable alternative? my plans for HA are pretty much on hold until i can find something better than the onboard BMC controls...

A few years ago we purchased 3 rack mount power units model ap7900 on ebay. Luckily the Proxmox devs had examples using those as fencing devices. So setting them up was easy. We do not have expierence with other fencing devices.

Try searching here and on the net for 'fence' and 'cluster.conf' to check what others have done.

Also we use triple redundant power supplies , and fencing supports that. for exampe:

  <clusternode name="fbc241" votes="1" nodeid="1">
      <fence>
        <method name="power">
          <device name="apc11" port="4" secure="on"/>
          <device name="apc78" port="4" secure="on"/>
          <device name="apc88" port="4" secure="on"/>
        </method>
      </fence>
    </clusternode>

ah, thanks Rob, so i could easily get two PDU and connect each to my UPS and then configure my fencing to use both PDUs?

That is what we do.

How many nodes will you use?

a total of 7 nodes is the plan but i also have other servers in the cabinet that wont be virtualised
