Requirements for Virtual Appliance Version 99.0.0

Upgrading to version 99.0.0

Before downloading the upgrade package, ensure the following:

  • Rollback from R99 to R96 or R93.x is supported.

  • You are running a minimum version R93.x. If you are running appliance versions older than R93.x, or if the root (/) partition is less than 64 GB, you must deploy a new Virtual Appliance and import configurations from the old appliance. To learn more: Install a Virtual Appliance.

    Note

    If your Virtual Appliance uses a 64 GB root (/) partition, then you must ensure that at least 8 GB of free space is available before upgrading.

  • There is at least 25 GB of free space on the /opt/ns/upgrades partition where the upgrade package is downloaded. You can delete older versions of the appliance from the upgrades folder to free up disk space.

    To learn more: Upgrade the Virtual Appliance.

  • All the dhcp interfaces on the appliance are configured with a static IP, netmask and gateway.

  • Export the current appliance configurations to a different host. To learn more: Exporting Configurations.

  • To verify that the host is reachable, run the following telnet command.

    nsappliance> telnet host cz.archive.ubuntu.com port 80
Executing telnet as: ['telnet', 'cz.archive.ubuntu.com', '80']
Trying 217.31.202.63...
Connected to mirror-r-01.nic.cz.
Escape character is '^]'.

The following are the minimum hardware requirements to install and run the Virtual Appliance.

Component

Requirements

Physical RAM

32 GB

Processor

8-Core

Hard disk space

400 GB is the total disk space required across all partitions. This includes 96 GB for storing and processing logs and 304 GB for the root partitions which store the Netskope software, configuration files, and data files.

You must increase the disk capacity depending on the size of the logs that are processed daily.

For information on increasing the partition size, see "Increase the Size of the Partition" under Optional Configurations topic on the Knowledge Portal.

Note

Netskope recommends that you increase the disk capacity by 5 times the expected daily log collection size.

Appliance Software Version Support

Netskope Appliance software releases are available every 4-months and will have Netskope support up to two previous versions. Direct software upgrades are supported as long as the “from” and “to” software releases are within two versions apart.

Release number - Netskope appliance releases are designated by the form X.Y.Z where X, Y, and Z are integers. The individual digits represent release major, minor, and build number respectively. It gives 12 months for customers to move to a supported release. For example, appliance release 77 and older releases are deprecated when appliance release 99 goes live. Releases that are outside the Netskope support period:

  • Are not guaranteed to work with the latest cloud releases.

  • Are no longer tested by Netskope.

  • Do not receive hotfixes.

  • Do not receive new feature updates.

At our discretion, we may provide support for releases outside our support period. If a customer encounters an error in a version of software that is other than the latest release, Netskope may require the customer to upgrade to a specified later version to obtain a correction of the error.
