Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades

The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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

"As we needed to grow in capacity, we were able to do so without increasing footprint by replacing smaller devices with larger ones."

"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."

"The initial setup is very straightforward. You simply plug it in and turn it on."

"The back-end data reporting for Pure Storage is phenomenal. The data that you can see on the performance of your customers' array, so you can be proactive about upgrades or enhancements, and is a phenomenal tool to have access to as a partner. I haven't seen this type of stuff out of anything of the other storage systems."

"The compression and deduplication features help to make the best use of the capacity."

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

"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."

"I find Pure Storage FlashArray to be much better than traditional storage because it has a GUI interface. It makes the process of allocating the storage much easier, and most activities are automated. It is like clicking a button for every task."

More Everpure FlashArray pros

"The ease of management, the simplicity of the CLI, the speed of that interface, and the well-architected design of the product in general are valuable features."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

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

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"It has significantly lowered management cost, overhead, and everything else."

"I think probably one of the biggest benefits of this solution is that it is relatively easy to use and easy to understand."

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

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

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."

"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."

Cons

"I feel like there is too much automation; the user doesn't have any manual input."

"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."

"What I dislike about Everpure FlashArray is that in the replication, if it is in the pod, we cannot directly add devices to the pod without breaking the relationship."

"The solution is not cheap."

"I want to improve the overall service level of the solution."

"I would like to migrate to the cloud in the future and know how that would actually work with this product."

"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."

"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."

More Everpure FlashArray cons

"Tighter integration with cloud storage might be useful as a target for a variety of use cases."

"The expense for support and maintenance is a little bit on the heavy side."

"The disk reliability is not that good."

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

"It's been pretty stable, but we've had some issues. I wouldn't say it's poor, but the resiliency has been less than what we expect from an enterprise class product."

"It even has a component, which I would say is a bit lacklustre."

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

"We found a gap for smaller clients. Right now, the only offering is a huge, rack-sized storage device, and no more."

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."

"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."

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

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

"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."

Pricing and Cost Advice

"There is an annual or perpetual license required for this solution."

"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."

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

"It could always be lower, but it's okay."

"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."

"There are no licensing fees aside from the support."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

More Everpure FlashArray pricing and cost advice

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

"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."

"I think it is a good value for the price."

"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."

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

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