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