    All Flash Server/VSAN Configuration for Kubernetes on OpenStack

    pirx666 Novice

      Hi,

       

      for each (internal) customer we are deploying dedicated k8s clusters in OpenStack tenants. Currently our payload cluster size is 8 DL360g9 hosts with 2 x 14 cores and 512GB + Hybrid VSAN (1x800 + 7+900). We have to build new payload clusters and think about using All Flash. Currently neither the performance nor the amount of storage the customers will need is clear. We started with projects that demanded only little persitent storage, now they are growing and new projects are testing the platform.

       

      I thought about the follwing config:

       

      8 x HPE DL360Gen10 with 10 disk bays

      2 x Xeon 6154, 2 x 18 Cores @3.0GHz

      768 GB RAM

      P816i-a Array Controller

      2 x 800 SAS WI SSD

      4 x 3,84TB RI SSD

      3 x 562SFP NIC

       

      The SSD's would the be configured as 2 disk groups, with ~120 TB RAW capacity and ~45TB usable with FTT=1 and 30% slack space. If needed we can add 2 additional disks to each disk group.

       

      Does this look sane, any ideas for improvement or lessons learned?
