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.

Has optimized performance using cluster deployment and distributed file access but needs better visibility into network dependencies

IBM Spectrum Scale being software-based storage allows users to utilize any hardware supported or defined by IBM without dependency on physical hardware provided by IBM. This is one of the features I appreciate most because if you have existing infrastructure at your site but don't want to reinvest in hardware, you can purchase IBM Spectrum Scale software and deploy it as software-defined storage. Users can comfortably access data from their host to the storage host without relying on new network setup when deploying GPFS as it uses the existing corporate network. However, high-speed ethernet network is required. By adding switches to the same network where client hosts reside and deploying GPFS storage array, any file system created on the storage cluster can grant export permissions determining which hosts can access specific file systems. These hosts can directly mount them as remote file systems. The process is simpler compared to defining IQN for providing access to client hosts. Creating a cluster for clients with virtual machines or physical Linux/Windows machines requires installing GPFS services on client nodes, which creates a client cluster. Access is defined on the storage cluster for the particular client cluster, allowing all hosts in that client cluster to mount file systems with granted permissions.

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 reliability is very good."

"Everpure FlashArray has positively impacted my organization by increasing our agility and the ability to run our environment at high speeds due to the flash storage."

"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."

"This solution is very scalable."

"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."

"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."

"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."

"The zero latency and high IOPS utilization we observe with it are significantly better than other storage solutions."

More Everpure FlashArray pros

"Its great servicing high availability. That is what it is used for."

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."

"Spectrum Scale is one of the most important products in our environment now."

"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."

"It is a scalable solution."

"The profile share is a valuable feature."

"The high performance of the solution is its most valuable aspect; if you compare it to other storage solutions, it is much better."

"We tested a complete site loss with the initial loss of the complete data center and the system was always up."

More IBM Spectrum Scale pros

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

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

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

"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

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

"Storage. There could be better storage."

"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."

"If I need to change or troubleshoot the dashboard, I cannot do it without calling support. If I want to move something critical, I cannot do it by myself. The dashboard blocks me from changing those critical things."

"When creating a support case, visibility should be extended to others involved in assisting."

"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."

"They need to find another way of doing data protection, RAID is not working very well."

"I think the pricing for Pure Storage FlashArray is the major issue because all the great things come with the price, and a lot of customers simply are not willing to accept it."

More Everpure FlashArray cons

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"We do have some issues where Spectrum Scale does not work as expected."

"I believe there is no graphic user interface, so they should include it."

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"Integration with other vendors is not available. This feature would be very helpful."

"We do not feel as a company that the product can grow with us anymore, so we are not going to use it anymore."

"The solution's pricing could be better."

More IBM Spectrum Scale cons

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

"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."

"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

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."

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

"The price of the solution is not expensive."

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

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

"There are no fees for licensing. The hardware is paid for only once."

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

"Price per terabyte is substantially higher than their competition. We would like to see it drop."

More Everpure FlashArray pricing and cost advice

"The solution is costly but reliable."

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."
