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

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."
"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."
"It uses the same platform for connectivity so integration is seamless."
"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."
"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."
"The solution provides many controllers."
"The product is scalable and easy to expand."
"I would rate Pure Storage FlashBlade a ten out of ten."
"It is a well-proven, automated management tool in all dynamic provisioning, auto-tiering, great performance, parallel I/O​, cache speed mechanism, etc."
"The documentation repository is really useful and kept updated."
"I am very happy with this product's ability to adapt, increase, and modify existing infrastructures."
"I found the solution to be very stable."
"DataCore SANsymphony brings stability to the infrastructures, and the infrastructures are healthy after, along with the redundancy."
"This flexibility and scalability have helped our organization in practice because it is important for us as it decouples the storage management software from the physical hardware, creating a software layer of intelligence."
"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."
"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 most valuable features of the solution are that it is easy to deploy and the support is really good."
"VMware Software Defined Storage gives higher availability against data corruption."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."
"This is an easy-to-use product for adding flexibility to your storage solution."
"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."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
 

Cons

"I would like to see more deduplication."
"I want efficiency. FlashBlade doesn't have efficiency now."
"I would also like to see better support for CIFS workloads."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"I would like to see better integration."
"The solution is expensive."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"I have not seen ROI."
"There is room for improvement in the graphical interface."
"If you're dealing with big databases or transactional databases, it might not be the best-suited solution. The design of DataCore's solution isn't oriented towards this type of data."
"One area where the solution could improve is its software platform. Many customers have expressed dissatisfaction with the software running on Microsoft Windows."
"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."
"I think the performance reporting can be improved by adding historical statistics into a database for the purpose of comparing."
"The cloud reporting interface is quite poor compared to other vendors."
"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."
"The solution could be better packaged and marketed."
"There is room for more integrations and plugins into more storages."
"I'd like to see improved hardware compatibility"
"The performance is not as good as some competing products and reporting can be improved."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
"Simplifying the licensing model and making it cheaper would improve the solution."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"VMware Software Defined Storage should include a shared database on a standard version."
"The license model of the product is an area of concern where improvements are required."
 

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."
"Our licensing is renewed annually."
"The price is a little high."
"I rate the tool's pricing a seven to eight out of ten."
"The pricing for FlashBlade is between cheap and moderate."
"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."
"The price could be cheaper."
"The price of this solution could be made more affordable."
"The solution is cost effective."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"Make sure you are made aware of the annual subscription cost when purchasing."
"The pricing and licensing are better with DataCore."
"Pricing has improved but it is still expensive."
"The cost is at the same level as other storage solutions and it is easy to understand the licensing."
"DataCore SANsymphony's pricing is very high and should be much cheaper."
"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."
"VMware Software Defined Storage is a slightly expensive solution."
"The solution is very expensive."
"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."
"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."
"The product is quite expensive and is among the most expensive for this type of solution."
