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

"If I had to use VMware or Nutanix, the same application would take three nodes and provide 400,000 IOPS, or input-output operations, but with Sunlight, I can get four million IOPS for the same price, allowing me to run an application on much less hardware."
"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."
"It supports the latest technology of NVMe SSD, which is PCIe-based SSD, and it has very good IOPS performance as compared to vSAN because for the same system I get 1,000 IOPS with vSAN, and with Sunlight, I am able to get almost 10,000 IOPS."
"The most valuable features are its performance, simplicity, and synchronicity with vSphere."
"The most valuable feature is that it is software-defined storage. Also, being able to do maintenance on the fly is a real benefit: migrating off, updating, and then moving the guest back on to the nodes."
"It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them."
"The most important functionality is the ability to extend cluster storage and cluster computing power securely without loss of data."
"The management of servers was easy from a central standpoint."
"The most valuable features of VSAN are consistent and increased performance with a linear cost which helped us in our data center."
"One of the valuable features for us is the ability to restrict the performance capacity per client. Other solutions don't have this feature."
"Very good VCG notification feature."
 

Cons

"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."
"It lacks the bells and whistles that are typically associated with Amazon Services or Nutanix."
"Its reporting and dashboards need to be improved. It currently has very basic reporting options."
"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."
"Maybe incorporation of automation to build clusters in a more automated way would be beneficial."
"So, my criticism is aimed towards the current Flash-based client, which is utterly slow, and Flash itself being deprecated technology."
"Its integration with a hybrid cloud can be improved. Its scalability can also be improved so that it can be integrated with more than 32 nodes. The maximum number of nodes is okay, but our use cases could probably do with more nodes, probably up to 64. In terms of new features, it should probably have the basic support for high-speed networking spaces."
"I hear a lot of issues of stability whenever you go to maintenance, but people who are having spectacular experiences are not speaking the loudest so it can be hard to tell."
"I would love for this product to be cheaper and easier to configure."
"It is not a good price for small and medium-sized businesses."
"I would like to see it be more hardware-agnostic. Other than that, the only other complication is - and it has gotten better with the newer versions - that lately, once you're running an all-flash, if you need to grow or scale down your infrastructure, it's a long process. You need to evacuate all data and make sure you have enough space on the host, then add more hosts or take out hosts. That process is a little bit complex. You cannot scale as needed or shrink as needed."
"On the troubleshooting front, it was occasionally difficult for me to perform some troubleshooting."
 

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."
"I'd love for this product to be cheaper."
"It is too expensive."
"The product's price has been increasing lately...VMware vSAN is expensive."
"It is cheap. It is $0.02 a gig."
"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."
"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."
"We pay for a license to use the solution through our company CapEx and then we continue to pay annually."
"Perhaps a bundle, like Essentials, would allow more businesses to make the leap to the product."
