We rencently announced the release of the Cohesity’s DataPlatform Virtual Edition (VE). DataPlatform VE is an implementation of Cohesity’s software-only package designed and implemented specifically for VMware vSphere infrastructures. The virtual appliance is meant to serve the same principals requirements and characteristics Cohesity’s hyperconverged physical appliances satisfy in enterprise data centers, but at in cost-effective virtualized form factor for remote and branch offices (ROBO) and Edge-based infrastructures powered by VMware.
Cohesity customers with smaller remote locations in need of data protection, retention, mobility, and file services can greatly benefit from this type of implementation. Remaining true to the core value proposition Cohesity’s Hyperconverged physical appliance delivers, DataPlatform VE provide a simple, end-to-end backup and recovery solution with full VMware vSphere integration, and consolidate your files with NFS and SMB support. Extend DataPlatform from the edge to the cloud, with geo-replication capabilities to replicate data to centralized data centers, and native cloud integration with all major public clouds.
Let’s look at some of the specific characteristics of the virtual appliance and explore some of the requirements and capabilities a bit deeper.
Virtual Appliance Characteristics
- Cohesity Operating System installed on the virtual appliance configured with a replication factor of one (RF=1)
- Single appliance packaged in VMware’s native open virtual appliance (.OVA)
- Compute resource requirements – CPU (4/16 vCPU), Memory (16/64GB RAM)
- Virtual Disks – 3 VMDK (Boot VMDK, Metadata VMDK, Data VMDK)
- Network Interface – 1GB/10GB virtual NIC
- Data protection maximum capacity is up to 8 terabytes per appliance
- Scale out capability is limited to 1 appliance.
- High availability is depending on the underlying infrastructure availability and services (vSphere HA, etc.) to ensure the virtual appliance availability
Supported Configuration and Deployment Options
Demonstration – this deployment allocates the virtual appliance with 4 vCPUs, 16GB of memory and a 62 GB virtual disks for the Cohesity software. In addition, two additional drives need to be added to the virtual machine (metadata and data VMDKs).
The first disk will be utilized for the high IOPS performance metadata tier. For the metadata tier, Cohesity supports a maximum size disk of 50GB. Disks larger than 50GB for the metadata capacity are not supported.
The second disk will be utilized for the data tier. For the data tier, Cohesity only supports data tier disks in the range of minimum size of 60GB and a maximum size of 1050GB. The data tier disks should be larger than the metadata tier disk. All disks should be attached to the appliance with the independent persistent mode configuration.
Production – this deployment allocates the virtual appliance with 16 vCPUs, 64GB of memory and a 62 GB virtual disks for the Cohesity software. In addition, two additional drives need to be added to the virtual machine (metadata and data VMDKs).
The first disk will be utilized for the high IOPS performance metadata tier. For the metadata tier, Cohesity supports a maximum size disk of 400GB. Disks larger than 400GB for the metadata capacity are not supported.
The second disk will be utilized for the data tier. For the data tier, Cohesity only supports data tier disks in the range of minimum size of 410GB and a maximum size of 8400GB. The data tier disks should be larger than the metadata tier disk. All disks should be attached to the appliance with the independent persistent mode configuration.
Note: when adding the additional disks to the appliance, I recommend adding two additional virtual SCSI Controllers to the appliance, one for each disk independently and use the Paravirtualization SCSI settings for the disks. For the network adapter type use VMXNet3 for overall optimal results.
I can say that based on my testing and evaluation on DataProtect VE on one of my All-Flash vSAN clusters the results have been very impressive from a performance standpoint.
When it comes to simplicity, the DataProtect VE appliance is a lot easier to deploy since there is no racking and stacking servers and from a configuration standpoint, it is still just a radically simple as the physical appliance. Take a look at the deployment procedure in the demonstration below:
There are many compelling scenarios where DataProtect VE lends itself as an excellent solution. For scenarios where the requirements to protect and archive data are based on smaller capacity of data sets with range below nine terabytes. Also, another common scenario is when organizations want to use existing available hardware with the resource and capacity capable of supporting the Cohesity DataProtect VE appliance. There are a lot of use cases and opportunities where this solution can help enterprise and commercial organization be successful with their data protection requirements. Stay tune, there is a lot more to come!
