## Local Engineering HA Cluster # #KVM Cluster based on Proxmox Virtual Environment (PVE). 3 Node setup with centralized storage #to `Truenas Scale` installation. # #> #> **!!! WARNING !!! !!! WARNING !!! !!! WARNING !!! !!! WARNING !!! !!! WARNING !!!** #> #> You must shut down _**ALL**_ machines using shared storage before upgrading or rebooting the #> storage server. Failure to do so will result in corruption or loss of data. #> # # ## Network redundancy #- Nics 1-4 are for client access and are `bonded` for redundancy and throughput. #- Nic 7 is for primary cluster sync and `heartbeat` checks. #- Nic 8 is for management access of the cluster, and secondary heartbeat link. #- Nic 9-10 are `bonded` 10Gb links for dedicated storage access to the Truenas. # - This is a high speed link and has redundant access. The Storage Server has dual 10Gb links but at this time it is intended to break those links and use a single pair for backup and the other for user access. # # #> While the KVM Servers are part of a clustered HA environment the back end storage is not part of an HA or distributed file system. #> #> This means that should the storage server go down all VM's will be unavailable and potentially data corruption. #> #> **IF** Distributed files systems are required in order to withstand a storage server failure without service interruption is required, Proxmox natively supports working with `Ceph` distributed file systems. This would require installing at least 3 storage servers with 100GB interconnects for replication data between nodes. Proxmox would then connect to this storage server as its `storage repository` keyboard: en-us migration: network=10.10.22.66/24,type=secure
