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 documentation was plentiful and very helpful.​"
"There are many services that can be directly used which are not available in VMware."
"The solution is stable."
"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."
"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."
"vSAN provides default HA configurations, where if any host goes down, the VM moves around within the host. Even though the disks are local, the VMs moves around with the vSAN disk and vSAN provides a high availability on its own."
"The product is highly scalable and significantly supports our organization's needs."
"It's easy to use."
"Technical support is very helpful and very good at resolving issues."
"VMware vSAN is compatible with the legacy hypervisor solutions and most of the features are good."
"We find it easy to deliver this solution."
"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."
"Its ease of use is most valuable. It is easy to configure, and there is a unified interface, which makes things slightly easier."
 

Cons

"The pricing of Rackspace is quite high in the Vietnam market."
"It should have a single dashboard for cloud management and on-premises systems"
"The deployment process could be easy."
"The line migration is a problem."
"It could use more examples in different languages (API use cases).​"
"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."
"The pricing of Rackspace is quite high in the Vietnam market."
"Licensing costs are a little too high for smaller sized companies."
"This solution would benefit from better collaboration with Cisco for driver updates."
"I'd like to see better integration with the Update Manager, with respect to firmware updates for hardware."
"The product's complex setup phase is an area of concern where improvements are required."
"Integration could be better."
"The customer service is good but there is a cost for it. It does not come free."
"VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement."
"When you upgrade the vSAN, there are some issues like lost data and problems with the log. The log disappears. When you upgrade the solution, you must have several logs, so if you have some problems, you can check the log server to find them."
 

Pricing and Cost Advice

"I use it as an open-source tool."
"The pricing is low."
"The current pricing needs to meet the customers' expectations, posing significant issues."
"We pay a yearly licensing fee."
"VMware vSAN is a little bit expensive and we pay annually. We have an educational institute where we receive discount prices from VMware. We do receive a reasonable discount but it's still expensive."
"The vSAN is somewhat expensive to license."
"I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license."
"It is not that expensive, and it is not even cheap. If it is designed in a proper way, it has good pricing, but if you do oversizing, the price will be high. There are different licensing models."
"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
"The product is quite expensive, regarding the open source solution."
