HomeLab Stage XXXIX: Cohesity Cluster

After completing the last stage: HomeLab Stage XXXVIII: Dell VRTX is was time to invest a little bit more into my Backup and Desaster Recovery Infrastructure…..

I am a very early user of the amazing Cohesity Virtual Edition. I am running one VE inside each datacenter, one as the active part, replicating to the second site. Cohesity changed the Virtual Edition options, so it is now possible to create a VE Cluster 🙂

I deployed 4 nodes and configured each of them in the following way:

  • 8 vCPUs
  • 64 GB RAM
  • 1 x 62 GB vmdk (Boot Files)
  • 1 x 800 GB Cache
  • 1 x 4 TB Capacity
  • CPU Reservation
  • Memory Reservation including Pinned Memory
VM Hardware Settings for each Cluster member
Special Configuration for Pinned Memory (Performance Tuning)

The Cohesity Cluster is running on top of my Dell VRTX, which has the following datastores configured:

Dell VRTX Physical View
Dell VRTX Cluster VMware Datastore View

The Boot vmdks are running together with the Capacity vmdks inside the VRTX_SSD_Raid5 datastore. (8 x 3,49 TB SAS Enterprise SSD)

The Cache vmdks are running inside their own dedicated 900 GB Raid0 datastore. (4 x 900 GB SAS Enterprise Write Intensive SSD)

Cohesity Cluster VMs
Each Node has 4 TB of Capacity
The Main Cohesity Cluster inside Datacenter I has 17.5 TB of Raw Storage

The Cohesity Virtual Edition where the main cluster is replicating to, is running on my Supermicro Cluster.

SuperMicro Cluster VMware Datastore View
The single Replication Node has 7 TB of Capacity

The main Cohesity Cluster is replicating data to the secondary site. This can be configured per Backup Protection Job.

Replication Settings

My Data is protected inside Datacenter I, replicated to datacenter II and also transfered to other areas…..

AWS S3 (US + Germany) and Tape Configuration

I have several sources configured for the main cluster, the replication site has no sources defined. (It is only used for data replication)

I wanted to test every single backup option, that´s the reason why you will find Hyper-V and KVM….

All of my VMs (which needs backup) are configured inside the Cohesity within different Protection Jobs / Groups:

The icons on the right side showing the SLA and the backup status / location (Local, Replicated, Cloud and Tape)

I am using my Cohesity Environment not only for backups (the platform has so much more feautes). There are several different dashboard available:

Data Protection Dashboard
File Share Dashboard
Cloud Usage Dashboard
SQL Dashboard (SQL AAG Cluster inside my environment)
I use my Cohesity also for file shares (SMB, NFS and S3)
Cohesity can run Apps (Containers) for example AntiVirus for File Share Integration

As you can see all my HomeLab / HomeDC data is totally safe, using the absolute outstanding solution from Cohesity. I really like their product, because it is so easy to use but extremly powerful.
