Simplivity Federation Networking validation

[MikeJoyce]

Hello,

I'm currently planning a deployment for some clients, still doing discovery of their current systems.  I know they have two Lenovo Omnistack hosts present currently and the goal is to install two new HPE Gen10 nodes and retire the old ones after migrating the VM load, all under a single, shared VCenter instance.  My question is around the Federation/Storage networking.  I believe the existing legacy nodes are cross-connected 10Gb.  Can I create a new cluster for the two HPE nodes, cross-connect them separately? So, single VCenter, Single VC Datacenter, 2 VC Clusters and no 10Gb switching?  I believe this is the case but want to verify or I need to make a remediation plan to install new switches and uplift the 10Gb networking.  

Cheers!

Mike,

While technically possible to create another cluster for the new Direct Connected HPE systems, the migration of data from the existing Lenovo systems would have to be performed manually with that traffic goiing over the 1GB Management network to accomplish your goal. Different subnets for the new Federation and Storage networks would be needed if the HPE systems are deployed to a new cluster without a 10GB switch. VMs and backup data would be migrated manually over the Management network.

The preferred plan would be to use a 10GB switch, then the new nodes can join the existing cluster with the same Federation and Storage subnets, and all data from the Lenovo systems would migrate to the new HPE systems automatically as each of the Lenovo systems are removed from the federation.

Additional clarification, such as the manual migration of data, can be provided if a Support case is opened with the HPE SimpliVIty Support team.

Thank you for confirming.  I'm building out an options and recommendations list for the client and this will help out.
