CEO at Arsium
High availability and user-friendliness enhance infrastructure health and redundancy
I would rate technical support from DataCore SANsymphony a 10. Each time I contact the technical support, it's when I don't have a choice because it's very difficult for me on site, and each time, I have good people online who are able to help me solve the problem. Usually, the problems are not very technically difficult, but sometimes they are, and the support team is still there to help us resolve them. The majority of the problems are linked to licensing, so when the license has expired or the number is not correct, they are proactive and change things live, which is very good.

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

"The support is excellent."
"Auto-tiering to obtain performance at a lower cost without the customer having to purchase ultra-fast storage is great."
"It is a 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."
"For us, fault tolerance is the most important feature of DataCore."
"Storage is always available."
"The solution has 100% storage availability and we've had that for more than ten years."
"SANsymphony-V offers a comprehensive set of storage virtualization functions to build a very robust storage network that speeds up applications, ensures business continuity and facilitates disaster recovery."
"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

"Even though it is easy to administrate, the initial installation and configuration can be complicated."
"Deduplication works but implementing it is complex."
"Maybe adding a Linux data manager, and moving away from Windows."
"The main problem is there is no DataCore OS."
"If it could integrate to a cloud gateway, then we could carry it directly to storage, instead of having middleware in between the storage and the cloud."
"The heavy client mode console should be improved by having a web console to improve accessibility."
"Pricing can be confounding with many options"
"There is no way of quickly matching the exact size of a vDisk to a disk pool."
"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

"Make sure you are made aware of the annual subscription cost when purchasing."
"Pricing has improved but it is still expensive."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"The pricing and licensing are better with DataCore."
"The solution is cost effective."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"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 solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"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."
