Administrator Notes

This guide covers the aspects of installing, upgrading and operating a vJSA (virtual Juniper Secure Analytics) appliance on top of Kernel Virtual Machine (KVM). It is assumed the reader is familiar with KVM, virtualization and Ubuntu Linux.

The examples in this guide are being executed as follow:

  • Initial Install and storage expansion of vJSA image on Ubuntu 18.04 deployment of KVM.

We recommend the following system settings before you upgrade to JSA Release 7.5.0 Update Package 1:

  • Instantiate the JSA virtual machines on the same non-uniform memory access (NUMA) as the disk controller or RAID controller on the host system. This optimizes disk I/O operations and avoids crossing the QuickPath Interconnect (QPI).

  • Set the NUMA policy as strict for kernel-based virtual machine (KVM) so that memory and CPU resources are all allocated from the same NUMA.

  • For best I/O performance, metadata preallocation is recommended as a minimum. Full allocation of the disk is required for maximum performance and is recommended for all installations on the KVM.

  • Increase the amount of storage allocated to a particular partition on the disk image.

    See Prerequisites for Installing JSA 7.5.0 Update Package 1 qcow2 for more information.

You should be aware of the following:

  • The size of the qcow2 image is 17 GB when compressed, and 512 GB when it is uncompressed.

  • Ubuntu 18.04 LTS with KVM and Open vSwitch (OVS) are used to validate the image for the KVM.

  • Contrail 3.2.12 is validated to run with the image or Kilo.
