Prerequisites

Installation Prerequisites

The minimum supported size for a Portworx cluster is three nodes. Each node must meet the following hardware, software, and network requirements:

Hardware
CPU	4 cores
RAM	4GB
Disk `/var` `/opt`	2GB free 3GB free
Backing drive	8GB (minimum required) 128 GB (minimum recommended)
Storage drives	Storage drives must be unmounted block storage: raw disks, drive partitions, LVM, or cloud block storage.
Ethernet NIC card	10 GB (recommended)

Network

Open needed ports

Network
Open needed ports	Portworx requires different open ports depending on how it’s installed: Spec-based installations require all Portworx nodes to have open TCP ports at 9001-9022 and an open UDP port at 9002. Portworx on OpenShift 4+ requires open TCP ports at 17001-17020 and an open UDP port at 17002. Portworx also requires an open KVDB port. For example, if you’re using `etcd` externally, open port 2379. If you intend to use Portworx with sharedv4 volumes, you may need to open your NFS ports.
Lighthouse	If installing the Portworx Lighthouse management UI please open ports 32678 and 32679

Portworx also requires an open KVDB port. For example, if you’re using etcd externally, open port 2379.

If you intend to use Portworx with sharedv4 volumes, you may need to open your NFS ports.

Software
Linux kernel	Version 3.10 or greater.
Docker	Version 1.13.1 or greater.
Key-value store	Portworx needs a key-value store to perform its operations. As such, install a clustered key-value database (`etcd` or `consul`) with a three node cluster. With Portworx 2.0, you can use Internal KVDB during installation. In this mode, Portworx will create and manage an internal key-value store (kvdb) cluster. If you plan of using your own etcd, refer to Etcd for Portworx for details on recommendations for installing and tuning etcd.
Disable swap	Please disable swap on all nodes that will run the Portworx software. Ensure that the swap device is not automatically mounted on server reboot.
