Featured Reviews

MikaelHellström - PeerSpot reviewer
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.
SigfridCecillon - PeerSpot reviewer
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.

Flexible and scalable file system for growing storage needs
Gluster FS is used for various purposes, including virtualization, collaboration, and data center environments. It is also applied in personal environments. Some specific use cases mentioned include scaling a three-terabyte file system into a 12-terabyte file system with minimal downtime Gluster…

Quotes from Members

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

Pros

"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 performs well and it is also very fast."
"The product is scalable and easy to expand."
"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."
"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."
"We can capacity plan at a greater level than we used to."
"FlashBlade offers low latency, high throughput, and seamless scalability."
"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 DataCore system has been rock solid since we have been using it - from 2007 on."
"It's a software storage solution that can scale as we like. There is also has a parallel feature that enhances the performance of the storage solution. We can separate storage and computing, and we can scale these two parts of the platform to meet business needs efficiently."
"I'd have to say that the biggest improvement gained by using SANsymphony has to be the performance of the product."
"It allows data to be available from two DataCore servers."
"The solution's most valuable feature is its versatility, with there being support for all new hardware technologies and platforms, disc mirroring and very effective auto tiering."
"Good security with this 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."
"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."
"It's very easy to upgrade storage."
"The price tag is good compared to the amount of data and high availability provided."
"The technical support team is excellent."
"Notable features of Gluster FS include flexibility, scalability, stability, and ease of use."
 

Cons

"I would like to see more deduplication."
"It would be nice if you could store file-based in the same box with the same technology."
"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"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."
"The feature that we're waiting on is better integration with the cell services."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."
"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."
"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."
"We are waiting for container support (on the roadmap), as well as a user-friendly full web-administration capability, and an improved API."
"There is room for improvement in the graphical interface."
"The alert system could have more features."
"I think an easier way to open a service call, right through the DataCore GUI, would be an improvement, especially when there is an urgent issue."
"There is no way of quickly matching the exact size of a vDisk to a disk pool."
"When I sometimes reboot for maintenance, the connectivity from the iSCSI initiator host could be improved."
"The performance of the solution must be improved."
"There is a feature in Red Hat’s commercial version that could be beneficial if integrated into the open-source version."
"The system should be more intuitive and easier to manage."
"The user interface could be simplified."
 

Pricing and Cost Advice

"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 is a little high."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"I rate the tool's pricing a seven to eight out of ten."
"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"Licensing fees are paid yearly."
"Our customers have seen a reduction in TCO."
"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
"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."
"The pricing and licensing are better with DataCore."
"The solution is cost effective."
"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."
"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."
"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."
"If you need cheap storage, but still need high availability, it's a good product to look at."
