E Small DSR VM Configuration
Many customers do not need the capacity provided by even a single pair of standard
size DSR DA-MP VMs. The fixed configuration in this section is for customers who
need the following configuration:
- Relay or RBAR applications
- 6k MPS or less (assuming an infrastructure equal to or better than the X5-2 processors used for the benchmark tests)
- 5K or less RBAR entries
- No IPFE
Table E-1 Minimal System VM Configurations and Affinity Rules
VM Name | vCPU | RAM (GB) | Disk (GB) | Max Config | Redundancy Models | Affinity/Placement Rules (Per Site) | Notes |
---|---|---|---|---|---|---|---|
DSR NOAM | 4 | 8 | 120 | 1 Pair | Active/Standby | 2 VMs for each DSR network in any site. VMs to be deployed on separate servers if possible. | Two NOAMs are always required to support upgrades, but they can be on the same server if only one server is available. |
DSR SOAM | 4 | 8 | 120 | 1 Pair per DSR NF | Active/Standby | ||
DA-MP | 4 | 8 | 120 | 1 or 2 per DSR NF | 1 or 1+1 | The 1+1 configuration should have the DA-MPs on different servers. | There is a little value in having redundant DA-MPs (1+1) if they are on the same server, since the server is the thing that is most likely to fail. |
