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.

Unified storage solution supports cross-vendor replication and diverse industries

One of the most valuable features of IBM Spectrum Virtualize is its virtualization capability. It allows for the creation of stretched clusters, which are crucial for running Linux-based workloads that need mirroring for boot disks. The solution also provides asynchronous and synchronous replication, supporting operations across different data centers. Its deployment options across public, private, and hybrid clouds add to its versatility.

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

"The most valuable feature is it never goes down. We can expand and create volumes."

"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."

"The reliability is very good."

"It is fast and reliable. It works."

"Redundancy and the fault tolerance of the platform are the most impressive."

"When users don't call wanting to kill me, that's ROI."

"It has improved the way our organization functions by improving the resilience of our infrastructure by quite a bit."

"The biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."

More Everpure FlashArray pros

"The most valuable feature is its reliability."

"The most valuable feature for sure is the abstraction of the storage."

"It improves a lot of functions for our clients, the high availability is the best thing, I have been working with it for 15 years, and it's one of the most stable products that IBM has."

"IBM provides exceptional technical support, which I rate as the best along with Cisco."

"We are happy with the support that IBM provides us."

"It provides transparency, because of its advanced copy features."

"I like that it can virtualize more than three hundred storage providers."

"The most valuable feature for me is its ease of use."

More IBM Spectrum Virtualize pros

"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."

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

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

Cons

"Reports of performance and LUN utilization could be improved."

"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."

"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."

"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."

"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."

"When it comes to Everpure FlashArray ports shown in the GUI, it would be better if, when one of the Pure array ports went down, there was a possibility to highlight that particular port which has gone down."

"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."

"I would like to see box-to-box encryption on replication included in the next release."

More Everpure FlashArray cons

"Technical support is sometimes good and sometimes okay."

"Anything which improves performance and the ability of our systems would be a nice."

"Because we're so big, they have a little bit of trouble tracking all the products and making sure we get connected with the reports, but, in general, they are very good."

"The disk reliability is not that good."

"Adding features for data deduplication is one area of improvement."

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

"Cheaper pricing and GUI should be developed in HTML5 as opposed to Java."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

More IBM Spectrum Virtualize cons

"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."

"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."

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

Pricing and Cost Advice

"We feel that the pricing is fair and the licensing process was easy for both."

"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."

"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."

"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."

"The price was more favorable than Dell EMC."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."

"It's expensive, but you get what you pay for."

More Everpure FlashArray pricing and cost advice

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

"This solution came as an additional cost for the TSM package we chose."

"It has a lot of advanced functions for a reasonable price."

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"We would like the CPU cycle to save more on the licensing costs for us."

"The entry point of pricing for this product is the most amazing price ever in the industry."

"Do a proof of concept, if you are not comfortable jumping in, but do it."
