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.

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

"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."

"The most valuable feature is its data reduction."

"Overall, I am sure that Everpure FlashArray is the best option on the market."

"It has made working with storage as easy and simple as it should be."

"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."

"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."

"You can even review the devices from your phone. You don't need to be connected to your company's website or VPN to access alerts and reports. While you can't manage the devices using your phone, you can review all the important details about the machine."

"I have seen a huge increase in speed and performance on our databases."

More Everpure FlashArray pros

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."

"Using snapshots allows us to automate production database refreshes to development environments in minutes, rather than in hours."

"So coupled with the simplicity, performance, and just absolute ease of use of the management of it, I don't know why anyone wouldn't buy it."

"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."

"The speed and, for us in particular in what we're doing, the data de-duplication."

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

"From my perspective, it is a huge success fulfilling everything we needed and more!"

More Kaminario K2 [EOL] pros

"The square footage for doing development is at a premium when dealing with government networks. To be able to put a lot of IOPS in a lot of high-speed performing drives in a very small location which requires very little HVAC with very little power, it is very valuable to us."

"Templates are already predefined for it. If you're coding it up, it will take two days. You can pick up a template right there from the API, and it just works for you. Implementation done in 10 minutes."

"Greater IOPS, speed, it's all-flash. So seeing that everything is going to all-flash, all SSDs, SolidFire fits right in there with the emerging trend in IT."

"Feature-wise, it is a good solution allowing users to monitor and simplify their networks. The solution also provides its users with flexibility by enabling them to utilize its extensions."

"Initial setup was very straightforward, easy."

"Individual settings you can put on each individual volume, if you want to do that."

"Provisioning times have gone down and a lot of the random errors from different things that we've seen across time kind of all went away."

"Overall performance of the solution."

More SolidFire pros

Cons

"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."

"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."

"If they could make it cheaper, that would be something."

"We haven't seen ROI."

"We have not had a good experience with the IBM device."

"I would recommend improvements in the graphical user interface, specifically a detailed hardware view that would allow us to see the individual drives and individual controllers more easily, as currently, they are presenting only a higher-level view."

"I can't see where they can make anything better, unless, of course, they lower their prices even more."

"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."

More Everpure FlashArray cons

"On the road map, I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"The management graphical interface needs more improvement."

"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."

"What I think would be a great idea for Kaminario is more visibility outside the US, when my customers start talking about AFA I notice they almost never talk about Kaminario, mainly because they just don’t know about them, and there are no local sales team to tell them about the Kaminario offering."

"The front panel of the drive shelf doesn't always seat firmly."

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

"There are some mid-market SMB customers that it may not fit the best for from a pricing perspective, but for the vast majority of our customers, once we aware of it and learned about the technology which it performed with, it fits a very useful metric."

More Kaminario K2 [EOL] cons

"On the negative side of it, I'm working on support, and I would get not enough detail or the support tech would say, "Check the manual.""

"We had some false positives, power supplies failing, and that's really been about it. We had a couple of glitches during some upgrade processes but nothing that was really concerning to us."

"There is room for improvement with a focus on creating a centralized storage system, functioning similar to AWS."

"The upgrade process could be better."

"I now know their best practices associated with allocating IOPS to your LUNs; I wish that was more apparent to me when actually configuring the system."

"We are looking for, potentially, on the Active IQ reporting side, to do reporting based on the datastore. Right now, I can report on the whole SolidFire, or I can report on just a certain datastore or a volume. I'd like to take all of my VDI infrastructure, which as an example would be multiple datastores."

"The technical support is really bad and has to be improved."

"I would like to see more of the fiber channel connect, legacy-type, Linux-type front-ends to it."

More SolidFire cons

Pricing and Cost Advice

"In terms of other contemporary arrays, Pure is something you need to have a use case for, as it's not priced for you to buy one off-the-shelf. If you have a use case, heavy lift Oracle Databases, any type of noticeable virtual desktop infrastructure (VDI), or need low latency and high throughput, you should consider all-flash at least and probably Pure Storage."

"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."

"We have an Evergreen Storage subscription, which I think is a great feature."

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

"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."

"Pure Storage has not helped to reduce our HANA licensing costs."

"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."

"The price is reasonable."

More Everpure FlashArray pricing and cost advice

"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."

"The licensing is all-inclusive."

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

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

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

"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."

"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."

"Based on what I heard from other people, its price was on the higher side."

"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"

"The price of this solution is more expensive than others."
