Nutanix 1350

I have been using the Nutanix Virtual Computing Platform 3450 and 3460 appliances on some of my recent projects.  I have been wanting to do some testing to see what these appliances are capable of, I mean other than hosting 5000+ VMware View desktops, but itís not like I can just go pull one out of production and fire up IOMeter, or install Hyper-V on it, or do some What-If-BadThingsTM happen like a hard drive accidently getting pulled or two nodes decide to power off at the same time.

Nutanix was kind enough to send me a Nutanix 1350 Virtual Computing Platform appliance to do exactly this.  The 1000 series is the little brother to the 3000 series.  Without having received Nutanix Official Sales Training(TM) I should clarify what the series numbers mean:

X (Series Number)
X (Number of Nodes)
X (Processor Type)
X (SSD Drive Capacity)
1 (1000 Series)
3 (3 Nodes)
5 (Dual Intel Sandy Bridge E5-2620)
0 (1-400GB SSD Drive)

Nutanix had also warned me that the appliance is rated to consume 1150W at 10-12A.  With all of the other equipment that I have in the office, my 15A circuit didnít look like it was going to cut it.  Time for a power upgrade!

However, something seemed to be missing to complete this power upgradeÖ attic access!  5 days, 10 trips to Home Depot, a stud finder, 1 new reciprocating saw, and 4 holes in the wall later I had finally installed a new 20A circuit!

This is also probably where I should put the disclaimer:

Found the back of the electrical panel!



Circuit breaker installed!



Time for unboxing!


Even though it came with rails, I donít feel like moving everything around in my lab rack, I want to play!  Iíll just set it on top and rack it later.


So now that I have it plugged in, letís see what this thing is going to cost me to run.  Thanks to Southern California Edison and the California Public Utilities Exchange Commission Iím in Tier 4 which costs $0.31 per kilowatt hour.  At 1.15 kw/hr * 24 hrs per day * 30 days per month * $0.31, Iím looking at a $256.68 increase in my bill next month. 

However, I plugged in my Kill-A-Watt meter and it shows me that these 3 nodes are only consuming 367 Watts.  At 0.367 kw/hr * 24 hrs per day * 30 days per month * $0.31, it looks like Iím only going to be paying an additional $81.91.  I realize that these numbers are at idle, so Iíll have to write another post once I get a load spun up.  Also, this load probably could have fit on my existing 15A circuit.  But at least I got to play Tim Taylor over the holiday break and get more power!

    Great post Josh, and looks like you had fun connecting the power. I’ve got a 3450 in my lab and I was surprised at how little power it consumes, even when I’m running tests against it. I definitely need to get one of those meters though so I can measure it against all the other lab kit I’ve got. You pay heaps for your power too. I’m glad I’m only charged $0.18 per kWh, and thats NZD too. Hope you have fun with the block. Those 1350’s are excellent for a lot of production use cases as well, including Management Clusters, DMZ Clusters, VDI, or Remote Branch Offices. So many use cases and so simple. Look forward to reading updates on how you get on with your tests.

    1. Thanks Mike! I just looked at your lab, you might have too much equipment for the little Kill-A-Watt. It starts beeping and making “I’m getting mad” noises at around 1800W. Maybe pull the power numbers off of your UPS?

      I am pleasantly surprised by the power consumption of the 1000 series! My whitebox/Drobo combo consumes about 275W, so for only 100W more I get 4.5x processor and 2x storage.

      If my order arrives next week, I should be able to take my meter and get power numbers from the 3460.
