Release 19.1R1 New and Changed Features
This section describes new features and enhancements to existing features in Junos OS Release 19.1R1 for vSRX (without vSRX 3.0 features) and vSRX 3.0.
For more information see Overview of the available virtual SRX models, vSRX and vSRX 3.0 .
Platform and Infrastructure
vSRX 3.0 support on Hyper-V and Azure (vSRX 3.0)—Starting in Junos OS Release 19.1R1, the vSRX 3.0 instance supports guest OS with 2 vCPUs, 4-GB virtual RAM and 18-GB disk space on Microsoft Hyper-V and Azure for improved performance.
[See Requirements for vSRX on Microsoft Hyper-V and Requirements for vSRX on Microsoft Azure.]
vSRX 3.0 support on KVM and VMware (vSRX 3.0)—Starting in Junos OS Release 19.1R1, the vSRX 3.0 instance supports guest OS using 9 or 17 vCPUs with single-root I/O virtualization over Intel X710/XL710 for improved scalability and performance.
[See Requirements for vSRX on KVM.]
vSRX 3.0 support for Nutanix Enterprises (vSRX 3.0)—Starting in Junos OS Release 19.1R1, vSRX 3.0 can be deployed in the Nutanix enterprise cloud. You can launch vSRX 3.0 instances for Nutanix using Acropolis Hypervisor (AHV), and ESXi KVM, and HyperV Hypervisors.
With vSRX 3.0 support, Nutanix enterprises can secure their multi-cloud environments with advanced security, consistent management, automated threat remediation, automation, and effective micro segmentation. A secure and automated multi-cloud without the overhead of operational and management complexity can be deployed easily.
