Latest Raspberry Pi Cluster server?

Recommended Posts

Posted (edited)

Just seen the spec for the upcoming Raspberry Pi 4. Now each one can have up to 4Gb RAM!

 

I wonder if a cluster of them would be able to run a modest server happily? I dont really know how Wurm would run on cluster - does it support multi-threading?

 

Raspberry Pi 4 specs

  • SoC: Broadcom BCM2711B0 quad-core A72 (ARMv8-A) 64-bit @ 1.5GHz
  • GPU: Broadcom VideoCore VI
  • Networking: 2.4 GHz and 5 GHz 802.11b/g/n/ac wireless LAN
  • RAM: 1GB, 2GB, or 4GB LPDDR4 SDRAM
  • Bluetooth: Bluetooth 5.0, Bluetooth Low Energy (BLE)
  • GPIO: 40-pin GPIO header, populated
  • Storage: microSD
  • Ports: 2 × micro-HDMI 2.0, 3.5 mm analogue audio-video jack, 2 × USB 2.0, 2 × USB 3.0, Gigabit Ethernet, Camera Serial Interface (CSI), Display Serial Interface (DSI)
  • Dimensions: 88 mm × 58 mm × 19.5 mm, 46 g

Depending on how the cluster is setup, probably yes. A raspberry 4 could be able to run a Wurm server again the question is how fast it can do I/O, that will matter the most.

If that is the issue probably few things could be reworked for that... maybe you could wire an ssd to it? i/o solved if it's just disk performance thing.

I'd not call a cluster of 55$/ea raspberries .. cheap, only bonus to this is the power consumption 😕

This might get me away from Odroid.  I still like the HC1/HC2 and want a H2 though.

well thats the thing - for a small server 2 or 3 of these would do RAM wise - would the processing power be enough? If so thats a £150 server - I would most definitely call that cheap.

 

And the power consumption is a huge bonus, they pull something like 5W each? - It would cost me £50 a month to run my PC 24/7 - a cost I cant afford whereas a cluster of these would be far more doable

Log in server needs to be beefy, otherwise its not going to cope with the joined cluster servers.

That Pi has USB 3, you can get really good SSDs that use USB 3. -- I bought a Corsair Voyager GTX for my portable Debian a few years ago. The specified I/O speeds are not a lie. Otherwise you'd have to get a really pricey micro SD card with a high speed class.

Quite curious as to how this is looking.

 

Has anyone tried it yet, if so what were the results?

I've just won a 2GB one yesterday so I might get myself at some point to do a test on it - setting up a default WU server to check how it works out.
