Hi, for the management of DTT transmission architecture, covering only M&C requirements for 100-250 elements across headend and remote sites, could we use 1x server with the specs below catering for installation of DM, Cassandra and Elastic? Functionalities expected will be element and service management along with redundancy grouping, alarming, trending, alerting, visual layout and dashboards.
- 16 core CPU with min 10K passmark
- 64 GB RAM
- 2x 250GB SSD (Raid 1) - for OS and DM
- 2x 1TB SSD (Raid 1) - for Cassandra
- 2x 1TB SSD (Raid 1) - for Elastic
- Windows Server OS
- 2x 1GBPS NIC
- Dual Power Supply

Looks OK to me. Only the CPU seems to be a bit on the low end for all three things together. I assume you would run Cassandra and Elastic in 2 separate Linux VMs and DataMiner in a Windows VM. You can oversubscribe a bit on CPU cores, but with 16 cores, the elements are hopefully not the real heavy ones...

Do you plan to run DM/Cassandra/Elastic all from the same machine (everything local to the Windows Server)? Or could you open up for separate Linux servers to run the DBs, as assumed in the first answer?
