Fast and flexible with good fault tolerance
The main problem is there is no DataCore OS itself; there is nothing better than one complete solution from one solution provider. We had a lot of issues. It was really disappointing to see that DataCore blamed Microsoft for the problems, Microsoft blamed Lenovo hardware, and Lenovo blamed Datacore. DataCore should have an OS specifically designed and optimized for managing storage workloads. Only the storage system should have access to encryption and authentication mechanisms to safeguard stored data. The future DC system should be integrated with the DC Hardware, this will enhances interoperability and simplifies the deployment and management of all storage products.

The initial setup is straightforward, but the solution has strict compatibility methods
I use this solution to make a few-to-one storage from the internal disk to the servers The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses. There are strict compatibility methods.…

Quotes from Members

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


"It is a stable solution."
"I found the solution to be very stable."
"For us, fault tolerance is the most important feature of DataCore."
"SANsymphony is flexible, with many potential options for implementation. SANsymphony's can be used with VMware, Hyper-V, or even with a hypervisor agnostic approach. It can also be used for strictly physical non-virtualized solutions."
"It is a very stable solution."
"CDP is an important feature for avoiding data loss in the event of ransomware attacks. You need more storage capacity, however, you get the possibility to return at any time and use the data saved up to that point. The recovery is much faster than with a classic restore."
"The features I have found most valuable are the active-active, or so-called grid technology, and the integration into our VMware-vCenter."
"Mirroring is the most valuable feature because I can provide a high-level of service and optimize the use of obsolete storage."
"Its technical support is excellent."
"The most valuable feature are the caching capabilities using the storage class memory."
"The most valuable feature is that there is no single point of failure."
"The initial setup is straightforward."
"The performance, reliability, and affordability has been most valuable."
"The flash ability, in terms of tiering and caching, is amazing"
"It's mainly about the storage expansion, like in hyper-converged solutions."


"The solution is constantly evolving."
"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."
"One limitation of this solution is that it's Windows-based, e.g. one requirement to install DataCore SANsymphony SDS is putting it on a Windows server machine. It relies on Windows and that is a limitation because there are some customers who are looking for non Windows systems."
"I think an easier way to open a service call, right through the DataCore GUI, would be an improvement, especially when there is an urgent issue."
"I'd like to see the company make the renewal of the software cheaper."
"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."
"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."
"We are waiting for container support (on the roadmap), as well as a user-friendly full web-administration capability, and an improved API."
"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."
"It is difficult to get a hardware compatibility certification for the solution."
"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."
"I think the online documentation needs a lot of work and so do the sizing tools."
"Documentation management could be improved"
"More optimization could be done in terms of mirroring."
"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

Pricing and Cost Advice

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"Make sure you are made aware of the annual subscription cost when purchasing."
"The solution is cost effective."
"We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly. They have three different features, and you have to pay extra for those."
"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."
"Pricing has improved but it is still expensive."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"Cost-wise the product is one of the more affordable within the category of products."
"The solution is expensive."

Questions from the Community

What is your experience regarding pricing and costs for DataCore SANsymphony SDS?
Good sizing is the basis for a stable and high-performance environment. It is important to plan in sufficient reserves. It can make sense to license a higher number of TB if this puts you in a bett...
What needs improvement with DataCore SANsymphony SDS?
It's difficult to say if something is missing in this solution. Maybe we'd like to manage the raid on the disk directly in SanSymphony. We essentially use RAID5 for our SAS disk and SSD, and now we...
How does VMware vSAN compare with Microsoft Storage Spaces Direct?
We found VMware’s vSAN was easy to set up, configure, and manage compared to other solutions we considered. It is best suited for small- to medium-sized organizations. It is easy to create load bal...
