IT Manager at Regin Dalarna
Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

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.

Data security and performance excel but integration and licensing need improvement
I used Nutanix for its hyper-converged infrastructure capabilities and VMware Site Recovery for disaster recovery.  Additionally, I worked with VMware Software Defined Storage both internally and with partners to consolidate servers into one solution The most valuable features of VMware Software…

Quotes from Members

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

Pros

"I would rate Pure Storage FlashBlade a ten out of ten."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."
"The solution provides many controllers."
"The most valuable features are the Metro clustering, and disaster recovery."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."
"We can capacity plan at a greater level than we used to."
"For us, fault tolerance is the most important feature of DataCore."
"DataCore SANsymphony brings stability to the infrastructures, and the infrastructures are healthy after, along with the redundancy."
"Storage is always available."
"Oracle OLTP benchmark to test how it improves the performance while using flash drive NVMe."
"The synchronous mirror allows us to operate a fully redundant storage solution that is distributed across two sites."
"I am very happy with this product's ability to adapt, increase, and modify existing infrastructures."
"It is a stable solution."
"I'd have to say that the biggest improvement gained by using SANsymphony has to be the performance of the product."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"This is an easy-to-use product for adding flexibility to your storage solution."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"The most valuable features of the solution are that it is easy to deploy and the support is really good."
"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."
"VMware Software Defined Storage gives higher availability against data corruption."
"The single management panel is the main feature that is wonderful for the customer."
"The solution is simple to configure and provides good performance and less footprint."
 

Cons

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."
"It would be nice if you could store file-based in the same box with the same technology."
"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."
"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."
"They need better integration with public clouds along with a better hybrid solution."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."
"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."
"There is room for improvement in the graphical interface."
"NVMeoF should be implemented. This protocol will play a major role in storage infrastructure in the future."
"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."
"I would like to see reporting added, such as a monthly connectivity report."
"I still see room for improvement with DataCore SANsymphony in the area of alarm and task management."
"I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays."
"The license model of the product is an area of concern where improvements are required."
"VMware Software Defined Storage should include a shared database on a standard version."
"Simplifying the licensing model and making it cheaper would improve the solution."
"I'd like to see improved hardware compatibility"
"The performance is not as good as some competing products and reporting can be improved."
"There is room for more integrations and plugins into more storages."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
 

Pricing and Cost Advice

"The product is very expensive."
"Our customers have seen a reduction in TCO."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
"The price could be cheaper."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"I understand that it is competitively priced compared to other brands."
"Our licensing is renewed annually."
"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."
"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"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."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"Pricing has improved but it is still expensive."
"The solution is cost effective."
"The product is quite expensive and is among the most expensive for this type of solution."
"The solution is very expensive."
"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."
"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."
"VMware Software Defined Storage is a slightly expensive solution."
