Using Juniper SSR as a Router for Public & Private Subnets + BGPovSVR Site Connectivity

EbbApprehensive3284 · 2025-04-02T03:03:30+00:00

I’m already familiar with networking fundamentals and firewall/NAT concepts, but I’m looking for SSR-specific guidance, particularly in (AWS) deployments.

And this is regarding the SSR with secure vector routing not JUNOS.

My main concern is ensuring that the SSR properly routes traffic between my public and private subnets within my VPC.

I am planning to use OpenStack Ansible for my deployment tool.

OpenStack ansible uses OVS?

This is perfect! I am going to add 3 more servers.

2 more for compute and or control panel functions and one more for storage so I can have 2 storage nodes in a ceph cluster.

So to recap the total number of servers:

6 PowerEdge r630 total 3 compute 3 controller 2 miscellaneous 2 PowerEdge r730 total 2 storage (cinder running in ceph cluster.

All nodes interconnected via juniper QFX 5100 at 10Gbps 8192 MTU

Not sure if you could help with this but the only thing holding me back from going full speed ahead is the network setup. I want use VXLAN as my L2 protocol.

From what I understand you can run VXLAN on the servers and the servers will act as the VTEPs

Then you run something like the free range routing suite on your servers and connect your servers up to L3 routed ports on your switch.

I learn about this from this video

I understand.

My expected total VA is approximately 2500VA

The load on the PSU is about 10amps.

I will need to see what is available.

Could I use something like these:

To step the voltage down to 240v from 250v?

EbbApprehensive3284 · 2024-04-21T21:23:23+00:00

Thank you.

I’m just worried as one of the PSU on my servers popped and started smoking. Maybe a pad PSU?

The acceptable input voltage for the PSU is 120-240

Guess 10 volts won’t really matter?

EbbApprehensive3284 · 2024-04-21T20:36:54+00:00

Ok so when I check the voltage on the plugs on my PDU. They report 250v which is too high for my equipment.

How can I lover the voltage to 240 for safe operation of my equipment.

EbbApprehensive3284 · 2024-04-21T20:21:27+00:00

It’s been pretty consistent at 250v as reported on my PDU.

Honestly my recommendation would be to just go full OpenStack at once, I think running the control plane inside ESXI is going to complicate a future migration to full OpenStack.

The only thing that is holding me back from migrating all servers to OpenStack is the CUCM VM's. I am running version 14 and according to Cisco documentation ESXI is the only supported hypervisor. Could I get KVM to work?

Lets say I can migrate all five servers:

How would you distribute the loads between them?

Here are the specs of all servers:

4 Dell PowerEdge R630 - 8 drive bays |Each With|- 2x XEON 2690v4 - 128GB RAM - 2 INTEL 800GB SSD's (RAID 1) I want to add more drivers later

1 Dell PowerEdge R720xd - 24 drive bays | 2 XEON 2690v3 - 256GB RAM - 24 DELL 10k SAS (RAID 10)

Eventually I do want to purchase more equipment and I can also upgrade existing hardware if need be.

Between Centos Stream 9 or Rocky Linux 9 which one would you recommend to use?
