Managing mixed RAID workloads has improved data protection and delivers strong performance
VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The initial setup isn't too difficult."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The open-source nature of OpenStack provides significant value."
"The solution is stable."
"It created a reusable library with OpenStack features."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"I like the tolerance of VMware vSAN."
"It is easy to use. It is easy to implement for us, and it is also easy to maintain for the customers. It is not necessary to buy some extra devices and talk with other vendors."
"vSAN has just one datastore. so customers do not need to think where to put their VMs, how to design the physical disk RAID, the LUN size, the LUN mapping, etc. when they use NetApp/EMC/HDS or other storage systems."
"The vSAN features we've found most helpful are live application migrations and storage policies. It has storage, policies, application, and DRS policies. Automation is there."
"High availability is a valuable aspect of this solution."
"The product’s ecosystem is better than Nutanix’s."
"The most valuable features are secure IOPs and LAN security."
 

Cons

"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"It could use more examples in different languages (API use cases).​"
"The deployment process could be easy."
"The pricing of Rackspace is quite high in the Vietnam market."
"So for the main stability, there have been a couple of issues that I've experienced."
"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"It should have a single dashboard for cloud management and on-premises systems"
"It is an expensive solution."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."
"The only negative point relates to the licensing. If you want multiple, different servers, it costs money, but you have all the capacity for vSAN. You do not reach the data, but the processor arrays and the current architecture."
"The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do."
"Customers who are using Essentials Plus or even Essentials have to pay for technical support. However, they should not have to pay for support."
"The platform's cost affects the business. This particular area needs improvement."
"We plan to switch products since the hardware nowadays is a little bit outdated and we need to scale up a bit."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
 

Pricing and Cost Advice

"The pricing is low."
"I use it as an open-source tool."
"The solution is relatively expensive compared to similar products."
"The product’s pricing is a bit higher than other solutions."
"​I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee.​"
"I'd love for this product to be cheaper."
"With the new pricing model, it's expensive for the customer."
"This is a cost-effective product. It's a bit cheaper than the other solutions."
"There is a license to use this solution and we pay approximately $30,000 annually. There were not any additional fees required other than the license. The solution is expensive."
"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."
