Performs well, effective, and has responsive remote technical support
Sunlight is a scalable solution. It supports on-premises and distributed deployments, as well as public deployments. It has a single pane of management so I can manage all of my VM installations in a distributed manner. It also has a footprint, that allows me to operate on Edge. If for example, you have a retail shop with 2,000 locations and they use a networked point of sale system, or if you are Chipotle and they have so many locations and they have to use a backend system at each location. At the moment, these are all standalone systems that operate with very little connection to the central. We could, however, connect and create a network using Sunlight. We can virtualize and run with Edge thanks to Sunlight. This allows us to operate and obtain high-end computing on Edge for retail. Sunlight is a startup. I am not sure how many users they have, but we have been using it constantly and using the technology to bring in customers.

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 performance and small footprint of this solution are its most valuable features. I am able to obtain and use more than 90 percent of the physical hardware capacity."
"It supports the latest technology of NVMe SSD, which is PCIe-based SSD. It has a very good IOPS performance as compared to vSAN. For the same system, I get 1,000 IOPS with vSAN, and with Sunlight, I am able to get almost 10,000 IOPS. In terms of features, it has almost all the features, such as HA and centralized dashboards. It can be managed centrally, and the visibility of the system is very good. They also have very good technical support and customer or partner training."
"vSAN Health is a feature designed to monitor the health and performance of the vSAN environment. It's crucial for us and our customers to frequently check on this to ensure everything is operating smoothly."
"VMware has been around for a long time are are doing a decent job at catching up with the latest technologies i.e. bringing in kubernetes and containerization. Overall, this is a great tool for virtualization."
"The deduplication and compression are excellent."
"I like the scalability and the fact that it reduces your total cost for storage over several years."
"The product is highly scalable and significantly supports our organization's needs."
"We didn't only choose vSAN; we chose VMware because of SR-IOV, which is more on the hypervisor level and not on the vSAN storage. It's part of the whole system."
"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."
"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."
 

Cons

"Its reporting and dashboards need to be improved. It currently has very basic reporting options. It should also be made easier to deploy on Unix operating systems. It is easy to deploy on Windows and Linux, but it is currently not easy to deploy on Unix."
"My recommendation would be to add this technology to Azure, Microsoft Azure so that we can bring it to the market, or deploy it on public clouds such as Microsoft Azure and Google. It is currently only available on Amazon's public cloud."
"Its price could be improved. It is too expensive for our clients."
"I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up."
"It could be more robust. The latency is also an issue for us, and the reliability. I would like it to be faster and a little more flexible."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
"I would like for the next release to be a bit cheaper."
"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."
"The interface is a little complicated, it could be simplified with more graphical gadgets. We have many servers, and the built-in functions, such as rate configuration, are a bit complex."
 

Pricing and Cost Advice

"There is an operating cost for the VDIs, which is an additional cost. However, the licensing fee is half that of VMware or Nutanix."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"This is a cost-effective product. It's a bit cheaper than the other solutions."
"Its reasonable, compare with other storage vendors"
"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."
"The price is expensive."
"I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap."
"It is too expensive."
"The only problem I have with VMware is the price. It is a good product, but it is expensive."
