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

"The documentation was plentiful and very helpful.​"
"The open-source nature of OpenStack provides significant value."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"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."
"There are many services that can be directly used which are not available in VMware."
"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."
"It created a reusable library with OpenStack features."
"One of the valuable features for us is the ability to restrict the performance capacity per client. Other solutions don't have this feature."
"It's completely hyper-converged, so it's very convenient."
"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."
"vSAN is easy for deploying and maintenance, so some customers can do service themselves."
"The solution is simple to use compared to other solutions, such as Hyperflex, VxRail, and Nutanix"
"It helped us survive power outages in one of our data centers, then continued to function without a hitch."
"Stretched Cluster is one of the big features that we use across multiple data centers."
"The product's initial setup phase was very straightforward."
 

Cons

"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"So for the main stability, there have been a couple of issues that I've experienced."
"The deployment process could be easy."
"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."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"It should have a single dashboard for cloud management and on-premises systems"
"The line migration is a problem."
"It could use more examples in different languages (API use cases).​"
"I am not satisfied with VMware support, particularly with the reaction times, SLAs, and those kinds of issues."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"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."
"We often run out of space but we have enough capacity for memory and CPU. It's difficult to find the balance between storage and memory CPU."
"The product's complex setup phase is an area of concern where improvements are required."
"The solution could be improved by having more filtered and multiple view volumes instead of a single view."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
 

Pricing and Cost Advice

"I use it as an open-source tool."
"The pricing is low."
"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."
"The licensing cost is high and should be taken into account."
"This solution requires the purchase of a license."
"I feel the pricing to be reasonable."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."
"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."
"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."
