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."
"I think vSAN's stability is good. It's an underlying solution for both on-prem and in the cloud, especially the VMC on AWS stuff too. VMware has been around for a long time, so it's pretty stable."
"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."
"The technical support is good."
"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."
"vSAN is easy for deploying and maintenance, so some customers can do service themselves."
"Stability-wise, I rate the solution a ten out of ten."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."
 

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."
"It would be ideal if the solution offered some intelligent monitoring."
"I would like compression and deduplication to be offered for offloading hardware, instead of doing it with software. That would be nice."
"Integration could be better."
"It would be ideal if clients didn't need to monitor the solution on a daily basis."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."
"The solution must provide better customization."
"Lacks sufficient storage terabytes."
 

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."
"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."
"In comparison with other solutions, such as HP or Cisco, I find the solution to be quite pricey."
"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."
"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."
"The price of the solution package depends on the nodes and other factors. The cost some of our customers paid was $500,000. The licensing cost for the components is very good."
"It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."
"We are using the VMware vSAN ROBO which allows us to have a maximum of 25 virtual machines. The approximate cost is €10,000 for a perpetual license."
"Enterprise customers can customize their licenses according to their own needs and budget."
