This article describes the process for upgrading the memory allocated to a Junos Space virtual appliance.

Beginning with Junos Space 22.2, the virtual appliance requires a minimum of 64 GB RAM.

If a system was upgraded from 22.1 or earlier to 22.2 or later, it is recommended to increase the VM memory accordingly.

Minimum hardware requirements for Junos Space Virtual Appliance can be found at:  http:////www.juniper.net/documentation/us/en/software/junos-space22.2/junos-space-virtual-appliance-pwp/topics/concept/junos-space-virtual-appliance-deployment-overview.html

Upgrading the VM memory is also recommended if you observe the following:

• High memory consumption

• Slow or unresponsive GUI

• Performance degradation in Space applications

1. Power off the Junos Space VM

Shut down the virtual machine from your hypervisor (VMware, KVM, etc.).

2. Edit VM Settings

Navigate to the VM and open Edit Settings.

3. Increase Memory Allocation

Under the Memory section:

• Set the memory value to 64 GB (or higher, if applicable).

• Click OK to apply the changes.

4. Power on the VM

Start the Junos Space VM after the configuration update.

Validation

1. Log in to the Junos Space node via CLI.

2. Verify the total memory using the following command: # free -h

Sample Output

[root@space-005056a9eca5 ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:            62G         27G         34G         92M        1.3G         35G
Swap:           62G         36M         62G
