Featured Reviews

Senior Information Technology Engineer at Eta2u

All-flash storage has unified my clients’ workloads and has reduced TCO through efficient data services

The pricing and licensing of Everpure FlashArray is a problem because Everpure is considered more expensive than competitors. IBM, Lenovo, and Dell are more aggressive on prices. It is a very complicated market, especially now, and I understand the prices are higher at Everpure because of the software and all the enhancements it has. However, in this competitive market, we have a big problem selling to customers that are on a tight budget. A product with better pricing would be a win in the end. The RC or C20, for example, was a very good product that I could sell more easily than other options. Everpure FlashArray//C is sufficient for most workloads and virtualization workloads if you do not have very large databases. A product like that helps, and perhaps a new product in the future that is a little cheaper than the current options would be a possibility to gain more market share. I see the return on investment clearly from using Everpure FlashArray, but the challenge is selling it to customers for the first time. There are many customers who fall in the sweet spot where they are too small for an X or even a C model. They need something a little cheaper, they have the money for a cheaper version, and they need the performance of a Pure system. These customers could be more easily approached if Everpure offers a version of a local device in the future that is even cheaper than the C-class. I am trying now to help customers understand the concept behind AG1. I know that AG1 is not profitable if capacity is less than 50 terabytes. However, some customers would be very willing to pay for 25 terabytes in a cloud operated by Pure and to have it accessible with very good speed. We will see what the future brings.

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.

Meets our customers' needs but they should move towards high-level scaling

I the product already has scalability features, but in terms of size maybe they could do more to work with parent storage and move to high-level scaling. That area, I feel, is a place where there could be some more options in this solution. It would be a way to improve the scalability in another direction, maybe options to scale out rather than just up. So far we have done very few installations. So maybe in the coming days, weeks and months, we would be able to come up with some additional features that are needed, but right now the product has the competitive features that our clients need.

Quotes from Members

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

Pros

"It simplifies the overall management. We don't have to worry about storage anymore."

"With this program, all of our applications are able to perform faster and this enables us to provide faster platforms and services to our customers and employees."

"Now with Pure Storage, our developers work a lot faster and more efficiently which has definitely improved our productivity."

"It’s easy to set up and support is excellent."

"Now they are trying to add more and more applications because they're getting better performance and stability."

"The solution has probably reduced my power use substantially."

"This improves our organization because we can just set it up and we forget about it, everything works, and we do not need to worry about storage or bandwidth issues."

"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."

More Everpure FlashArray pros

"It is a very stable solution."

"The support is excellent."

"As DataCore SANsymphony SDS is good software, it doesn't need to improve much."

"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."

"The most valuable feature of DataCore SANsymphony SDS is its high availability. This solution also exhibits good performance and has high stability."

"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."

"For us, fault tolerance is the most important feature of DataCore."

More DataCore SANsymphony pros

"Automatic rebalancing is the feature saving administration time, and also auto rebuilding."

"Comparing other products that are competing with Dell EMC (Enhanced Memory Controller), Dell seems to us to always come out on the high-side."

"We are using it as the primary virtualization storage (both for internal corporate users and external customers) for VMware and Hyper-V virtualization platforms."

"The ScaleIO UI: EMC has been working with storage for a long time; therefore, they know how to clearly present any important data, including data flow and each drive's IOPS/bandwidth, and allow the user to easily monitor bottlenecks and problems, especially the rebuild and rebalance status of child objects."

Cons

"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."

"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."

"Automation could be simplified."

"It falls far short of protocol support."

"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."

"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."

"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."

"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."

More Everpure FlashArray cons

"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."

"Management could be improved. The management console sometimes reacts very slowly."

"Better integration into backup solutions like Veeam."

"The graphical interface is not always very stable."

"The cloud reporting interface is quite poor compared to other vendors."

"The heavy client mode console should be improved by having a web console to improve accessibility."

"Having an enterprise "Storage Dashboard" that can show capacity, usage, performance, and any issues would be very beneficial."

"DataCore should integrate its own file server into SANsymphony."

More DataCore SANsymphony cons

"There is room for improvement in the area of horizontal scaling."

"Ecosystem around the product: There is no built-in system for viewing history data, such as volume IOPS. We have to provide graphing by Prometheus and Grafana, which would be a good new feature in ScaleIO."

"It would be nice to set minimum IOPS per volume, besides just the maximum, to be able to satisfy this demand from customers out-of-the-box, not by calculating number of disks, etc."

"I think ScaleIO already has some features for scalability as it is part of the reason for the product, but in terms of size, maybe they should try to address parent storage."

"If they could introduce a write cache feature, the product would be perfect overall."

Pricing and Cost Advice

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"No storage device is cheap, but Pure Storage is fairly priced and offers what you pay for. You get all the licenses in the future when you purchase a license."

"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."

"The solution is expensive."

"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."

"Pure has been flexible with us on the pricing models."

"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."

"There should be quite a bit of reduction of TCO with just licensing (and stuff) because we run the VM environment off it."

More Everpure FlashArray pricing and cost advice

"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."

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

"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."

"DataCore SANsymphony's pricing is very high and should be much cheaper."

"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."

"The solution is cost effective."

"The pricing and licensing are better with DataCore."

"Pricing has improved but it is still expensive."
