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

"There are many services that can be directly used which are not available in VMware."
"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."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"Customer Service: Top. Technical Support: Top"
"The documentation was plentiful and very helpful.​"
"OpenStack allowed for mass uploading of images to Akamai cloud services."
"It created a reusable library with OpenStack features."
"Have a look at the simplicity of vSAN and how it easily integrates into the existing management tools."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"There is not a lot of maintenance required."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"It has a single pane of glass for management and operational control, which is the most valuable feature. The integrated storage is also valuable."
"The most valuable feature is the ability to continue our business needs and have higher visibility."
"VMware provides primary and strategic development features, in working with us in the federal government."
"I would suggest customers use VMware vSAN because VMware offers a stable solution with good hypervisors and the best features compared to other solutions."
 

Cons

"So for the main stability, there have been a couple of issues that I've experienced."
"The deployment process could be easy."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"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).​"
"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 pricing of Rackspace is quite high in the Vietnam market."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much."
"It would be much improved if we could somehow integrate a better backup with it. Right now, we're using Veeam and it's okay, but I would like more of a VDP vSAN solution. That would be excellent. The VDP, at least the last time we looked at, it was just not quite there."
"The main problem we had was hardware compatibility, finding the right hardware that was certified."
"The quality of the customer service and support depends on the vSAN case. For example, if I open ten cases, maybe two or three get resolved quickly. But the other cases have a slow response."
"Expand the hardware compatibility list – it's pretty short. Definitely also the diagnostic and monitoring could be improved."
"We have encountered some scalability issues and got a couple of performance tickets."
"What I would like to see, for the really small customers, is the ability to have two nodes."
"The platform's cost affects the business. This particular area needs improvement."
 

Pricing and Cost Advice

"The pricing is low."
"I use it as an open-source tool."
"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."
"From a cost perspective, it is expensive. From a usability perspective, it reduces the overhead costs attached to its users' servers."
"It is cheap. It is $0.02 a gig."
"Every product is licensed with full support for a certain number of years. The licensing could be cheaper."
"The product's price has been increasing lately...VMware vSAN is expensive."
"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."
"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."
"Its price could be improved."
