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

"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."
"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."
"The solution's technical support is good."
"All orchestration and monitoring are routed to the cloud."
"The scalability of the solution is most valuable."
"The vSAN features we've found most helpful are live application migrations and storage policies. It has storage, policies, application, and DRS policies. Automation is there."
"High availability is a valuable aspect of 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."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"The simplicity, as well as the integration with virtualization."
 

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."
"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."
"It is a memory intensive app."
"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."
"I would have liked it to have been more scalable. It's scalable but not as much as, for example, the ScaleIO systems were or the Kaminario"
"We do see weird things crop up every now and again. It will say that a drive gets kicked off even though it's fine, and we have to re-add it."
"The upgrading process could be simplified."
"vSAN has a significantly higher license cost post-merger."
"The product can be improved in a couple of ways. One of those would be that they have a lot of hidden features, that are through the CLI, that would be great to have in the GUI, or just be more open about those features. It's something called RVC. It's a tool in the back end. It's a really great tool, but I had to find it through Reddit. So more information on stuff like that would be great. Also, in the user interface, giving us more features and more reporting that we can do from vSphere itself would be helpful."
 

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."
"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."
"The price is expensive."
"It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive."
"From a cost perspective, it is expensive. From a usability perspective, it reduces the overhead costs attached to its users' servers."
"It is too expensive."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"We did consider other hyperconverged solutions. It usually came down to price. vSan was the most cost effective thing."
"This solution is expensive. Nutanix provides us with Acropolis Operating System (AOS) along with its hardware, while VMware provides vSAN, vCenter, and vSphere which all have separate licenses and costs."
