Installation Prerequisites

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

CPU 4 cores
Disk (/var) 2GB 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)
Open needed ports TCP ports 9001-9022 and UDP port 9002 on all Portworx nodes. Also open the KVDB port. (As an example, etcd typically runs on port 2379)
Lighthouse If installing the Portworx Lighthouse management UI please open ports 32678 and 32679
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.
