4 node R710 cluster

I'm currently on a 4 node CE cluster of R710's.  Don't have the Xeon specs handy at the moment.

 

I have the following memory in them:

96GB

128GB

144GB

144GB

Kind of strange memory setup, but it's how the chips went in.

 

I bought a 256GB consumer SSD for each and either RAID0'd a pair of 300GB HDD's, or bought a 1TB laptop drive.  It's ugly, but it works.

 

I have 14 VM's at the moment.  It's a mix of house things and experimental things.  Plex, Unifi controller, Grafana, Netatmo data collection, Node playground, Chromecast server, Unifi Video, Wink API server(non-functional).

 

Outside of the Nutanix, I have a Nortel 48 port GE switch, Unifi UAP-AC-LR AP's(2), Unifi cameras(3).  I also run a 18TB Unraid server for the bulk storage.  The top R710 is a Windows Server I use for running Handbrake.  Smiley Happy

Re: 4 node R710 cluster

I've been in the business for about 25 years.  Over that time I've made a point of offering to take equipment to the dumpster/recycler whenever it's been ethical to do so.  That cabinet was a company that was closing down and was literally going to throw it out.  Got a friend with a pickup and we loaded it up.  It was a bit challenging to get it in the basement, but when you take the sides and doors off it's not too heavy.  Now that it's down there, it's probably never moving.  My current problem (pun intended) is the power.  The older, smaller UPSs aren't up to the task.  If I get a power blip at all, they bounce.  UPSs cost money, though.  It's fine for the house, even though it's not great for the WAF when Plex is offline.  I've been able to test how CE recovers from abrupt power outages!  No problems, so far...

Re: 4 node R710 cluster

Nice setup and thanks for sharing?

 

A couple of questions on your grafana setup.

 

what backend DB ar you using for grafana?  Influx?  prometheus?  how are you getting the nutanix metrics in the DB?

 

I've just started evaluating prometheus here at work, and pretty impressed with it so far and this was one of my next steps was to start trackign nutanix metrics.

Re: 4 node R710 cluster

Thanks!  I'm using InfluxDB and Telegraf for the collection.  Basically, I'm using Telegraf to do an SNMP get.

The telegraf.conf has the OIDs I'm using for Nutanix.
