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.

Sync to Central and edge protection mitigate my risk in our branch offices
The level of tech support depends on who you get. There are some techs that just read the script and ask you if you’ve rebooted, but once you get past that - or if you have a very technical issue - the support is great. They really know the product and get you up and running again ASAP.

Quotes from Members

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

Pros

"DataCore SANsymphony brings stability to the infrastructures, and the infrastructures are healthy after, along with the redundancy."
"The support is excellent."
"For us, fault tolerance is the most important feature of DataCore."
"Redundancy and improved performance in terms of storage with auto-tiering are the most valuable features."
"I'd have to say that the biggest improvement gained by using SANsymphony has to be the performance of the product."
"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."
"Supporting of Automated-Storage-Tiering (AST) is a good feature that saves money."
"DataCore has helped provide flexible, highly available, high-performance storage that otherwise would have been outside our price range."
"That is why Riverbed SteelFusion has delivered a masterclass technology that not only abstracted and virtualized the storage vendors’ unique logical storage structures, it has made it logically closer and seamless to the branch applications from a performance and experience perspective."
"Sync to Central and edge protection mitigate my risk in our branch offices. All services that need to be local to the user exist on local servers. Users run applications and access data locally while the data is constantly being synced to Central, and protected. If an edge device fails, we can recover quickly."
 

Cons

"I'd like to see the company make the renewal of the software cheaper."
"Better integration into backup solutions like Veeam."
"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."
"We'd like to manage the raid on the disk directly in SanSymphony."
"I would like to see reporting added, such as a monthly connectivity report."
"Unified storage (all block, objects, and files) should be in a single storage pool with unified storage concepts, hence providing the user with whatever they want."
"Tech support is NOT good at all, even when buying the higher level support from them."
"The current view in the GUI is too simple and we cannot see clearly cold data or hot data."
"Setting up disks for use is a multi-step process that could use some refinement. Setting up a core-to-core replication or DR strategy is also cumbersome."
 

Pricing and Cost Advice

"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"Pricing has improved but it is still expensive."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"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."
"The pricing and licensing are better with DataCore."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"Price is an issue – this is expensive stuff. My advice is to beat up Riverbed as much as possible on price. These things are expensive and there is room for negotiation."
