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

"Storage is always available."
"DataCore SanSymphony helps us to have a real performant and secure storage system."
"We are now able to run a hot standby solution for our virtual systems with separated server rooms (in case of fire), and so we can minimize downtimes of our IT infrastructure."
"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."
"The support is excellent."
"In the time of using DataCore SANsympohny Hyper-converged-Infrastructure, we had no storage-related downtime in our environment."
"DataCore's ability to seamlessly move virtual volume data between storage pools as well as their synchronous mirroring has made maintenance and disaster recovery planning achievable."
"The platform's most valuable feature is its synchronous mirroring capability, which ensures bit-identical copies of data and offers excellent failover capacity."
"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."
"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."
 

Cons

"We are waiting for container support (on the roadmap), as well as a user-friendly full web-administration capability, and an improved API."
"We'd like to manage the raid on the disk directly in SanSymphony."
"The cost is becoming prohibitive since they moved to a subscription model."
"DataCore is currently working with Veeam software for a better integration; this is my only desired missing feature today."
"The management should take place via OS-independent access; here a web-based client would be desirable."
"DataCore should integrate its own file server into SANsymphony."
"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparison."
"For customers or technicians that don't speak and understand English, it could be great to have other languages support, all the more so given the number of countries in which SanSymphony is used."
"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

"The solution is cost effective."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"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."
"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."
"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."
"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."
