Storage platform has improved data performance and has provided reliable support for my clients
It's difficult to know how DataCore SANsymphony can be improved. I think DataCore SANsymphony could be deployed on Linux environments, which could be a great thing for clients. I would like to see the stabilization of the Veeam implementation in the future, and perhaps the integration or officialization of compatibility with Proxmox and XCP-ng. With Proxmox, it wasn't easy while integrating it with third-party solutions. It's working, but it was a bit difficult to deploy.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It allows data to be available from two DataCore servers."
"Inexpensive for the amount of storage."
"The synchronous mirror allows us to operate a fully redundant storage solution that is distributed across two sites."
"This flexibility and scalability have helped our organization in practice because it is important for us as it decouples the storage management software from the physical hardware, creating a software layer of intelligence."
"I found the solution to be very stable."
"Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great."
"DataCore gave us speed, redundancy, reliability, and works great with our backup system."
"The platform's most valuable feature is its synchronous mirroring capability, which ensures bit-identical copies of data and offers excellent failover capacity."
"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."
"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."
 

Cons

"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."
"Maybe adding a Linux data manager, and moving away from Windows."
"I see some good competition to DataCore SANsymphony at the moment. I don't think DataCore SANsymphony is the best option on the market at the moment as they still could learn something from their competitors."
"The only area I see lacking with DataCore is their support; it's not very good at all, and it's frankly very frustrating and has almost caused me to swear off the product."
"There is room for improvement in the graphical interface."
"The so-called hyperconverged infrastructure edition, sometimes known as vSan, should be addressed."
"I would like to see reporting added, such as a monthly connectivity report."
"Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial."
"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 lacks the bells and whistles that are typically associated with Amazon Services or Nutanix."
 

Pricing and Cost Advice

"Pricing has improved but it is still expensive."
"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"The solution is cost effective."
"Make sure you are made aware of the annual subscription cost when purchasing."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"The pricing and licensing are better with DataCore."
"There is an operating cost for the VDIs, which is an additional cost. However, the licensing fee is half that of VMware or Nutanix."
