We've selected different boards as our primary targets for the Lollipop Cloud project. Our team members will be working with these boards heavily and will prioritize supporting them. The boards were selected for their price ($25-$100 USD), specifications, and ease-of-use, keeping in mind our goal of making self-hosted clouds an accessible reality.
The [Orange Pi PC 2](http://www.orangepi.org/orangepipc2/) is a reasonably priced arm64v8 board. This board can be purchased as a full set that includes a board, case, and power supply. It's got enough RAM, CPU, and more to run a full self-hosted cloud for an individual, family, and maybe a little more.
It has 3 USB ports for additional WiFi adapters or USB disks. It also has a full HDMI connector so you can setup using a USB keyboard and TV/monitor/etc.
It does *not* have a WiFi chip on-board, be sure to remember a WiFi dongle if needed.
The [Orange Pi Plus 2e](http://www.orangepi.org/orangepiplus2e/) is an arm32v7 board. It packs 2Gb of RAM, 4 core CPU, lots of expansion options, built-in WiFi, built-in ethernet, and more.
Due to our community asking for boards that support large amounts of storage we've found and tested the following setups for more storage focused Lollipop Cloud builds. The below builds are "bill of materials" that outline our tested and working configurations.
### Nano Pi Neo2 + NAS Board
- [Nano Pi Neo2](https://www.friendlyarm.com/index.php?route=product/product&path=69&product_id=180)
- Select ```1Gb RAM``` model
- [Nano Pi Neo2 NAS Kit](https://www.friendlyarm.com/index.php?route=product/product&path=89_93&product_id=222)
- [Noctua 5V 60mm fan (NF-A6x25 5V PWM)](https://noctua.at/en/products/fan/nf-a6x25-5v-pwm)
- 12v 5.5-2.1mm barrel jack power supply capable of providing at least 3A of power
- 2.5" sata disk
#### Notes
- The 60mm fan can be mounted directly above the main board components at the back of the case by cutting a 55mm square hole in the top of the case as well as drilling 4 holes for securing the fan to the case.
- If you don't need/want the metal case you can select the ```Heatsink``` and ```1-bay NAS dock``` options on the main Nano Pi Neo2 product page and run it without a case
- If running the build without a case the [Noctua 5v 40mm fans (NF-A4x10 5V PWM)](https://noctua.at/en/products/fan/nf-a4x10-5v-pwm) fits perfectly on top of the Neo2 heatsink and will provide enough airflow to keep the build from overheating
- ZFS works well on this board if focused on bulk storage, samba (windows file sharing) and/or nfs
- The **ENTIRE** amount of usb, disk and network speed **COMBINED** will total between 50 and 75 M/s. The disk is attached to the usb controller which also seems to influence network io speeds in our tests. This will *not* be fast but it will act as (and feel like) a very capable USB2 disk running services attached to your network.
- Attach the 40mm Noctua fan to the SATA Hat heat sink, it gets very warm when under load and can easily become thermal throttled
- Attach the 60mm Noctua fan upright at the front of the main board + heatsink. The main board gets over 80C under load without active cooling is and is prone to thermal shutdown events
- There is no case that we've been able to find, this is a "naked build"
- Sata power splitters and sata -> pwm fan adapters can be used to provide >2 sata power ports for disks attached to the hat and powered by the hat
- Consider a 40mm or 60mm fan for cooling disks, you can double stick tape the disks together (use mutiple layers to allow about 2-5mm space between disks) and then mount a fan to the front of the disks to keep them cool
- ZFS runs in a *default* configuration on this setup, you do *not* need the module tuning in our documentation for this deployment. However, if using the 2Gb RAM model, using the 3rd tuning option from our documentation (the one with the most RAM usage) can help reduce zfs RAM usage and allow more services to be setup
If you're going to run services like NextCloud, Syncthing and/or Samba you will want to consider what kind of USB disk to use. I'd recommend a [Sandisk Cruzer Fit (link)](https://www.sandisk.com/home/usb-flash/cruzer-fit) or [Sandisk Ultra Fit (link)](https://www.sandisk.com/home/usb-flash/ultra-fit) or similar, low power flash drive. Full hard disks that aren't SSD's tend to be power hungry and can cause problems with SBCs.
- The author has had decent luck with the [ASUS USB-N13](https://www.asus.com/us/Networking/USB-N13/) adapter in client mode. Be minful of your 2.4ghz channel setup. If this adapter and your AP share a channel in 2.4ghz this adapter *will* drop packets and/or suffer disconnections
- The author has had very good luck with the [ASUS USB-N53](https://www.asus.com/us/Networking/USBN53/) in AP mode. *Both* 2.4ghz and 5ghz can used for AP mode at the same time.
