Prerequisites for 7-hour large scale production

• Specific hardware and software components used during this scenario

• Red Hat account

As part of this exercise, the steps provided will include fine-tuning Red Hat® Ceph® Storage and Red Hat OpenShift® Virtualization. The following software components are necessary for this:

• Red Hat OpenShift  (version 4.13.2 or higher)
• Red Hat Ceph Storage (version 5.3.2 or higher)
• Red Hat OpenShift Data Foundation (version 4.12.3 or higher)
• Red Hat OpenShift Virtualization (version 4.13 or higher)

This deployment scenario utilizes specific hardware for Openshift Container Platform and Red Hat Ceph storage.

OpenShift Container Platform hardware

• 132 PowerEdge R650
  • CPU: 112 cores (2 Intel(R) Xeon(R) Gold 6330N CPU @ 2.20GHz)
  • Memory: 512 GB (16  Micron MTA36ASF4G72PZ-3G2E7 32GB Ddr4 3200Mhz PC4-25600 Ecc)
  • SSD (root disk): 446.63 GB - 6 Gbps (MICRON SSD  MTFDDAK480TDT)
  • NVME: 3.2 TB (Dell Ent NVMe P5600 MU U.2 

Red Hat Ceph Storage hardware

• 12 * Dell PowerEdge R750
  • CPU: 40 cores (2* Intel(R) Xeon(R) Gold 6230 CPU @ 2.10GHz)
  • Memory: 384GB ECC RAM (12 * Samsung M393A4K40BB2-CTD 2666 MT/s)
  • SSD Root disk: 1.92 TB (1 *  SEAGATE XS1920LE70134)
  • SSD Disk: 1862GiB - 6 Gbps (20 * SEAGATE XS1920LE70134)
  • NVME disk: 1.8T - 3200 MB/s (4 * Dell Ent NVMe v2 AGN MU U.2 1.6TB)

With these software and hardware components in mind, we will explore a brief overview of the networking architecture for the Ceph and OpenShift clusters. In this example, the clusters are on a private lab VLAN uses the balance-alb bond using 4* 25 GbE ports creating a single 100GbE bond.

Now that the baseline needs are met, we’re ready to dive into this seven-hour journey to mass scaling of virtual machines.
