Featured Reviews

Sowjanya MV

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.

Uninterrupted upgrades accelerate performance with good support

I would rate the solution eight out of ten. It should be noted that in Pakistan, some parts are not readily available, and we need to import them from Singapore or other countries. We encountered an issue with a customer where the midplane failed and was not available. We had to wait for several days for a replacement, even in a 24/7 support case. Additionally, we faced motherboard failures in the customer's environment, encountering two motherboard failures simultaneously. We obtained one motherboard immediately, yet had to wait ten days for another. These issues should have been resolved promptly given the 24/7 support level.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

Quotes from Members

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

Pros

"The deduplication and compression rates are beyond impressive."

"All use cases for Everpure FlashArray are anything that requires a SAN should use it because it is the easiest thing on the market."

"It has a small footprint, as the current system is only four units per rack, it's got good speed for the price as it uses eMLC, an advanced type of SSD, and it's very scalable, and we're not paying for capacity as we get free controllers every three years."

"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."

"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."

"The performance and the ever-growing maintenance are the most valuable features of this solution."

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

"Now, with Pure Storage, we have totally eliminated that problem."

More Everpure FlashArray pros

"It is incredibly easy to manage; we’re getting the performance that we need, we plug it in and it works, and everybody forgets about it, which is what we need."

"I see the value in investing in 3PAR."

"Having moved over from a LeftHand, which was seven or eight years old, there's a massive boost in performance, and it has definitely improved the speed and the responsiveness of all our applications, which is always good."

"The solution is quite stable and scalable."

"We have not had a moment's down time."

"Probably the most beneficial aspect from my viewpoint is that it has reduced the amount of time that I spend administering storage requests by at least 50%."

"For our purposes, it’s the best SAN that we have found."

"I am a system integrator, so we sell a lot of 3PAR storage to our customers. Our business has increased compared to previous days."

More HPE 3PAR StoreServ pros

"Our holdup was disk I/O, so we did a PoC with Kaminario and we reduced build times down to fifteen minutes for a full build from two hours."

"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."

"The ratio between the physical storage and the storage we use is very high."

"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."

"I think this product hits all the big features of all the SANs that are out there, all the storage vendors that are out there and more."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

"Implementation of the solution is very simple."

"Improved performance by more than 50x on our application."

More Kaminario K2 [EOL] pros

Cons

"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."

"The interface lacks the same level of control as some other arrays I've used."

"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."

"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."

"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."

"The primary drawback is the cost, which can be prohibitive for small configurations."

"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."

"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."

More Everpure FlashArray cons

"Yes, we have had a few issues with stability."

"Technical support could be better. The guys you get on the phone generally are not very knowledgeable."

"At this stage I would rate it somewhere around eight out of 10, because there were some initial challenges in finalizing the design, etc."

"There are issues formulating the upgraded disk."

"Right now it is a big pain. It seems to work but we tend to get some latency behind."

"Sometimes control is rebooting and nobody knows why, so there are issues."

"Small bugs in the GUI that were resolved in the latest version."

"I would like to see a proper unified system (same controller serving both SAN and NAS solutions) such as NetApp offers."

More HPE 3PAR StoreServ cons

"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."

"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."

"I would like them to improve the look of the product’s external casing and shelves."

"The interface look and feel could be improved."

"There are a few areas where the system could be improved. Examples would be that the system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."

"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."

More Kaminario K2 [EOL] cons

Pricing and Cost Advice

"The price is reasonable."

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

"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 lost a lot of customers because we couldn't compete on price with other vendors."

"We have 16 or 18 arrays. We like to do the three-year support model so that we get Evergreen and therefore, we get free upgrades. We pay around more than 1.5 million dollars."

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

"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."

"My organization has a yearly license, but I believe that Pure Storage FlashArray has capacity-based licenses as well. I'm definitely happy with the pricing."

More Everpure FlashArray pricing and cost advice

"Its price is a bit high for adding another tree, but when we purchased it, it was okay with us. We had compared it with EMC and other solutions, and it was okay at that point in time. Our storage has a lifespan of seven to eight years. When you purchase it, you need to keep a headroom of around 40% to 50%. After three to four years, you generally plan for an upgrade. The price is not so bad today for two years or so, and within a year, I might find that I have to upgrade or increase the storage. This usually happens when there is a radical change or a new application has come that is consuming a lot of data, but generally, there is a plan for the amount of data that we generate and the storage upgrade."

"There was a one-time cost when we procured this product and there are no monthly or yearly licensing fees."

"We don't pay for any licensing fees."

"If HPE reduced the price of 3PAR StoreServ they would be more attractive to mid-range companies."

"We are going to buy eight nodes this year and eight nodes next year. Eventually, we are not going to want to buy large storage devices and probably utilize just storage, but in a different manner going forward."

"We have seen ROI. We are able to see more patients now, bringing more money into the practice."

"The price of the license depends. Some people expect more from the hardware. Some expect more from the licensing, and that is because you can receive several licenses nowadays, such as the terabyte license. You buy the storage, and you pay extra for the terabyte license for the software. There is a one-time purchase for the license and you pay annually for the maintenance."

"HPE 3PAR StoreServ is an expensive solution."

More HPE 3PAR StoreServ pricing and cost advice

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Kaminario is very competitive on price. They also have a pay per TB model."

"The licensing is all-inclusive."
