Technical Lead at Wipro Limited

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

"The speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."

"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."

"The product has not gone down in a year, so I would say that it is stable, and we haven't seen any high spikes in read/write latency."

"If I want a product which has reliability and high speed, and Pure Storage is the first name that comes out of my mouth."

"Their support is top-notch, and their NPS scores reflect this."

"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."

"The Pure Storage customer service is by far the best part of the product and organization."

"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."

More Everpure FlashArray pros

"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."

"I love Spectrum Virtualize."

"Good luck finding anything that does half of what it does."

"Stability has been outstanding."

"In my opinion, the quick restore, the low latency, and the ease of use are some of the most valuable features."

"I think Spectrum Visualize is a very good product to address a lot of problems."

"This is an absolutely outstanding product and anyone can use it with ease."

"The versatility is the main benefit, since it virtualizes everything, they use it for so many different things."

More IBM Spectrum Virtualize pros

"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."

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

"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

"Many high-end platforms from other vendors like Dell EMC or Hitachi, their backend has Active/Active architecture, unlike Pure Storage FlashArray which doesn't utilize an Active/Active architecture on the backend."

"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."

"The price of this solution is high and should be lowered."

"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."

"The overall scalability for this product could be improved as well as having a single console to management multiple arrays."

"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."

"There is not a great need for improvement, but better pricing could be beneficial."

"There are a lot of things to improve."

More Everpure FlashArray cons

"The product should have better management capabilities."

"In general, the migration is complicated. Though, it is case-by-case."

"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."

"I had a couple isolated problems with reliability, mostly related to replication, but I have been able to work through them."

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

"Level 1 technical support needs improvement."

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

"We've had some issues with the production rate behind SVC."

More IBM Spectrum Virtualize cons

"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."

"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."

"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."

"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

"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."

"Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."

"I would rate it a seven out of ten for pricing. It could be improved."

"It's a good price point and it's a solid product for the price."

"The pricing is very attractive and it delivers performance for the money."

"The pricing of Pure Storage FlashArray is reasonable."

"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."

"We consume it as a service, and that's actually something we really like, or at least I really like from the technical perspective. That's because it means there is no hassle when we need to upgrade arrays to add capacity. We just interact directly with technical counterparts, and we say, "Hey, we're filling up," and they say, "All right, here's another data pack." They ship it in, and we install it. So, the as-a-service model has worked very well. Given the outstanding data reduction rates, it has improved our profitability because we're selling allocated volumes as part of the cloud service or recovering those costs from our tenants. It is very efficient, but that has offset the premium price. It started out that way, but over time, as we've added capacity, the price per gig has gone down a lot because we have a lot of it."

More Everpure FlashArray pricing and cost advice

"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."

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

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

"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."

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

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

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

"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."
