SUSE Harvester vs. VMware vSAN

It's great for provisioning any kind of virtual servers, but for now, we use it to provision only servers for Rancher managed Kubernetes clusters. But we are considering to provision also virtual servers for all kinds of needs on SUSE Harvester in the near future, as it's getting more and more mature with every release.

The product is a must for enterprise & SMB segments as this gives a good value for money and the licensing policy is very well defined and cost effective for the feature set it provides. This is very well suited for organization which have multiple brand storage systems and would like to consolidate them all together, thus providing a huge storage capacity for the organizations data growth. The product becomes less appropriate in organization where they have single storage platform as the service provider would have the ability to consilidate all the storage systems. Hence this products may be under utilized.

• Fast to deploy new virtual machines
• It's easy to use
• Stable and ready for production
• Free and open source
• Has a strong community

• VMware runs VSAN certification programs to make sure the OEM sells validated nodes. It helps customers to select appropriate certified ready nodes like Lenovo ThinkAgile VX which comes factory configured and easy to set up.
• Hyperconverged solutions reduce real estate space and networking costs when compare with shared storage. The host overhead also less.
• Supports All-Flash (SATA and NVMe SSDs) and Hybrid vSAN with HDD and SSD. So customers can choose cost-effective solutions appropriate to their workloads.
• Supports different storage policies, RAID and duplication, and compression features and it makes a complete storage solution.

Incentivized

• It takes expertise to set up SUSE Harvester for production
• You need to get used to SUSE Harvester to be as "fluent" as in VMWare ESXi
• You need to well prepare for system upgrades

• We were a fairly early adopter of VMware vSAN and as such experienced several growing pains.
• We experienced a few bugs that took a few software versions upgrades to go mostly away.
• The biggest issue we had overall was with host drivers. Even with vSAN ready node compatible hosts, you have to be very careful that the drivers for NIC and RAID controllers are right.

Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.

Support is (as always forVMware) top notch and easy to work with. The majority of computer companies are outsourcing their tech staff, and it seems they do as well. But their guys know the product well and are quick to respond to your ticket (if the severity is right!).

We used ESXi for years and were happy with it. Then we implemented Rancher managed Kubernetes clusters with nodes provisioned on VMware ESXi. Later, when SUSE Harvester came out, we started to provision SUSE Rancher nodes on Harvester. Both VMware ESXi and SUSE Harvester are great products, and I think - we are keeping both, at least for now, when SUSE Harvester is a young project.

Our VMware solution is built in-house for the organization's private application, we don't want to put our data on cloud premises. Also, vSAN is a cost-effective solution for our environment. We have done the POC with both products to understand the Flexibility, Management, and cost. After the successful POC, we have chosen the VMware vSAN.

Incentivized

• We can provision more virtual servers
• It's cheaper than competitor products (tbh - it's free, if you don't need support)
• It's easy to manage when you get used to it

• we have realized savings in the licensing compared to traditional storage (over $500,000 over the last 5 years)
• we have realized ROI through efficiencies in our staff of approx $1MM (over the last 5 years)
• also, positive impact on the time to value/speed of implementation allowed us to realize business objectives (Over $1MM of ROI)
