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.

Quotes from Members

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

Pros

"The use of the RAM cache allows you to speed up the writing and reading of data while also allowing for a possible increase in performance by increasing the RAM on the servers."
"Our central storage has very high availability. DataCore SANsymphony ensures high business continuity."
"Excellent performance and reliability, and very low cost using home hardware."
"The best solution to build an always-on strategy, with zero downtime, very fast performance, and great flexibility."
"For us, fault tolerance is the most important feature of DataCore."
"The solution has 100% storage availability and we've had that for more than ten years."
"The better features are the synchronous replication and the management console."
"Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great."
"The customers who use DDN EXAScaler are happy, especially when using large AI clusters for training."
"EXAScaler provides amazing performance in terms of sequential read and random access, and it has a significant scalability advantage as it is scalable to petabytes."
 

Cons

"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."
"There is no way of quickly matching the exact size of a vDisk to a disk pool."
"I would like to see reporting added, such as a monthly connectivity report."
"For customers or technicians who don't speak and understand English, it would be great to have other language support, all the more so given the number of countries in which SanSymphony is used."
"I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays."
"Deduplication works but implementing it is complex."
"One area where the solution could improve is its software platform. Many customers have expressed dissatisfaction with the software running on Microsoft Windows."
"There is room for improvement in the graphical interface."
"One challenge with EXAScaler is during upgrade time, as it can be problematic when upgrading node by node. Additionally, it is not multi-protocol by nature, requiring additional hardware to support various protocols like NFS or object storage."
 

Pricing and Cost Advice

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"The pricing and licensing are better with DataCore."
"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."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"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."
"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."
