This week I got questions about the z/VSE Network Appliance (VNA).
To refresh memories I will provide details about VNA and how it is used. Then I will answer a question from Victor.
The z/VSE Network Appliance is available for z13, z13s and z14 and can be used with z/VSE 5.1, 5.2, 6.1 and 6.2. z/VSE was the first exploiter of the new infrastructure, called Secure Service Container.
VNA is available at no additional cost. It is provided on request. If you have a valid z/VSE 5.1, 5.2, 6.1 or 6.2 license, you may request VNA on the VNA web page - here. VNA will be serviced through the VSE/AF component of z/VSE.
Just a short description of the z/VSE Network Appliance. If you want to read more, please use my blog entry I posted in February 2016 - here.
The z/VSE Network Appliance (VNA) builds on the z/VSE Linux Fast Path (LFP) function and provides TCP/IP network access without requiring a TCP/IP stack in z/VSE. The appliance utilizes the new Secure Service Container introduced on z13 and z13s servers. The Secure Service Container is a new LPAR (partition) type which, along with an appliance installer, enables the secure deployment of software and firmware appliances. The Secure Service Container LPAR requires CPU resources (e.g. (shared) Intergrated Faciliy for Linux (IFL)) and disk storage. Compared to a TCP/IP stack in z/VSE, the VNA can support higher TCP/IP traffic throughput while reducing the processing resource consumption in z/VSE. z/VSE V5 and 6.1 systems connecting over HiperSockets to VNA need to run in an LPAR. It can not be accessed from a z/VM guest. With z/VSE 6.2 you can even access the VNA from a z/VM guest. For z/VM environments we also provide the z/VM IP Assist (VIA), available on z114 and z196 or higher. VIA provides network access for TCP/IP socket applications running on z/VSE as a z/VM guest.
I got the following question:
Are there any standard TCP/IP applications, that are provided with VNA ?
No, VNA is an appliance, it just provides the network access. The socket application has to run on z/VSE and connects through the Linux Fast Path to the VNA LPAR.
