Juniper released a new version of vSRX (formerly known as Firefly Perimeter) running Junos OS 15.1X49-D15) with more features, and forwarding capacity. The latest version was Junos 12.1 , so moving to 15.1 code is a big jump…I hope it doesn’t hurt!
The following features are new in Junos OS Release 15.1X49-D15 for vSRX:
- Naming update: the product formerly known as Firefly Perimeter is now vSRX.
- vSRX includes DPDK packet I/O support for higher throughput.
- SCSI virtual disk support has been added to existing IDE support for improved performance and to permit network-attached storage (NAS) integration.
- vSRX includes SR-IOV vNIC and VMXNET3 vNIC support for greater performance and hypervisor compatibility.
- vRAM has been increased to 4 GB and vDisk to 16 GB.
- vSRX includes KVM Ubuntu 14.04 and CentOS 7.0 support to take advantage of Linux improvements and tools enhancements.
- KVM images are downloaded in qcow2 format instead of the self-extracting .jva script used in previous releases.
- vSRX includes VMware vSphere 5.1 and 5.5 support to take advantage of ongoing VMware improvements.
- vSRX includes new architecture based on Linux and Junos OS for performance and flexibility.
