Questions on R-Series 5800s

Hello...Trying to bring up a new 5800

 

  1. What is the recommendation for port-channel. Can we create port-channel between two different pipelines?

i.e Ports 3.0,4.0,5.0 and 6.0 are in Pipeline-1 and Ports 7.0,8.0,9.0 and 10.0 are in pipeline-2. Can we create a LAG with 3.0 and 7.0? Plan on using a 10G link for HA and was planning to convert 6.0 to 10G and connect between two R-series

 2. When deploying a tenant, Should we just leave it as "Recommended" for Provisioning instead of "Advanced" and have 18 vCPUs if plan on having just one tenant. Not sure how much Virtual disk size is recommended.

Any recommendation for Virtual Disk Size?

 

3. If we want to have additional tenant, is it best to leave the tenant at 14 vCPU or can we change it later and What is the impact? Just existing tenant restart?

  • For the LAG question, yes 
    on rSeries a LAG can span ports from different pipelines as long as the member links are configured with the same speed and type. So in your example, using 3.0 and 7.0 in the same LAG should work if both ports are configured identically. I’ve seen deployments where links from different pipelines are used without issue, but the usual recommendation is still to keep link characteristics consistent.

    For tenant deployment, I usually start with "Recommended" unless there is a specific reason to manually tune resources. Advanced provisioning is mainly useful when you want to customize memory instead of using the default vCPU-to-memory ratio

    For virtual disk size, leaving the default is generally fine to start with. Tenant disks are thin-provisioned, so the configured size does not immediately consume that amount of physical storage.

    If you want to adjust vCPU or memory later, it can be changed, but the tenant must be moved to the Provisioned state and then deployed again. Depending on your setup (HA configuration, traffic mirroring, etc.), this may have service impact during the redeploy.

  • Hi InquisitiveMai​,

    1. Can you create a LAG between 3.0 and 7.0? Yes, you can.
    2. Plan on using a 10G link for HA. Ok, proceed. :)
    3. Yes, leave disk size as recommended. No need for advanced or manual configurations.
      Read here about tenant image types and sizes:

    4.  

       You can setup a tenant with 18vCPUs. If you want to downsize the tenant and redistribute the CPUs, you have to power off the tenant.
      Same if you want to increase the CPU count of a tenant.

  • Thank you AXI_MJ​ and Daniel_Wolf​ , I configured them with recommended settings. Had another question, If we have multiple tenants, there will be only one HA  and cannot be separate for individual tenants in a HA setup? What is the recommendation

      Most important is to understand that HA is between tenants, not between rSeries hosts.
      Tenant-A1 on rSeries1 will have HA with Tenant-A2 on rSeries2
      Tenant-B1 on rSeries1 will have HA with Tenant-B2 on rSeries2
      You can have separate HA VLANs per HA cluster, or you can use the same VLAN. As long as there is no duplicate IP / IP address conflict, both will work.
