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."

"Technical support is very helpful and very good at resolving issues."

"It is scalable, overall. If you need to add storage, it makes it easy to scale by adding additional hard drives into the existing servers or you can add storage by just adding more servers."

"Its ease of use is most valuable. It is easy to configure, and there is a unified interface, which makes things slightly easier."

"Being hyperconverged, it simplifies what equipment we have to buy."

"The product is highly scalable and significantly supports our organization's needs."

"One of the most valuable features of this solution is that it is stable."

"It is very well known in the industry, and there are a lot of technical resources around it. This is a big thing for me because, at the end of the day, when you implement it, you need to support it."

"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."

More VMware vSAN pros

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."

"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."

"I would like to be able to limit IOPS."

"If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much."

"They can improve the manageability of the solution to make it more simple. It is not that complicated, but it will be good if they can make it more simple."

"I would love for this product to be cheaper and easier to configure."

"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."

"External storage would be a good thing to have in the next release, something other than iSCZI, something a little more, not HA, a little more production-oriented, than iSCZI."

"vSAN has a significantly higher license cost post-merger."

"On the DevOps side, if there could be more automation it would be more helpful."

More VMware vSAN cons

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."

"Its reasonable, compare with other storage vendors"

"I would like to see this technology be made available to smaller businesses, who might benefit from high availability but struggle with the entry fee."

"It is fairly cost-effective for entry to mid-level performance based on the underlying hardware components."

"If they could reduce the cost, it would be better. Licensing costs are something that they could take care of. If you are a smaller and strong IT team, then VMware vSAN is a very good product. If you want to expand in the service provider space, then you will have to go for an open-source solution like OpenStack. We are now looking at OpenStack because we sell licensing costs. We are a service provider, so the IT component data is a substantial component in our overall costing. We feel that OpenStack might help us to cut down the licensing cost. Therefore, we are looking at SAS storage instead of vSAN. SAS is open source, but it is not wise to have open source without having the backend support. We are using RedHat SAS, and it is an open-source solution. You can also have a free version, but we are using it with support from RedHat so that we have somebody to back us up in case we have a problem. If you do normal business, then IT expense is 1% or 2% of the total turnover. The higher licensing costs sometimes don't make difference to the big companies who are not service providers and are using it only for their internal use. For them, the IT cost is 1% or 2%, but for an IT service provider, the IT costs will go up to 15% to 16% of the total cost of the operations. This is where the licensing costs become irrelevant. For example, the licensing cost of using VMware, VC, and vSAN is 8% of my monthly revenue. Every month, I pay about $35,000, and, with the revised plan, it will be something like $50,000 or revenue of 600k per month, which means almost 8% of the revenue is going into VMware licensing. In a very competitive world, 8% as a cost element is huge. So, if I can bring it down to 2%, I save 6% in revenue expenditure. In terms of profit, 6% of 30% is something like another 25% increase in my profit. My profit can be almost 25%. It would be 20% to 25% in case I am able to handle the licensing costs and bring them to a very low level. Because these IT costs are substantial for us, that is why we are going with OpenStack. OpenStack has a limitation that it requires more hardware. There will be some increase in the hardware cost, but overall we will save 5% to 6% of our licensing cost by using OpenStack."

"The solution requires a license. The payment is on a yearly basis and It is not overly expensive."

"The product’s pricing is a bit higher than other solutions."

"It could be cheaper."

Reviews from Real Users

Below are some reviews and helpful feedback written by PeerSpot users currently using the VMware vSAN solution.

PeerSpot user Yves S., CEO, Cloud Evangelist at Comdivision Consulting GmbH, says, “vSAN gives us a lot of advantages when we need to expand resources. We have an overall larger host infrastructure, and we split that up for specific customer test and use cases. In that specific scenario, we can easily add more hosts or reduce the number of hosts in the environment.”

A reviewer who works in Infrastructure Security explains, “The ease of use is great. The initial setup and upgrade process was pretty straightforward. And, technical support is great.”

Laurent N., Director at Softlogic, comments, "The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
