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

"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."

"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."

"The best features Everpure FlashArray offers are the speed and dependability, which are the main features that we get from Pure; it is faster than its competition, and we do not have any documented downtime from it ever."

"Support has been helpful."

"The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."

"Pure Storage FlashArray provides immediate benefits to our customers with its easy setup process, allowing for instant use and rapid realization of advantages."

"If you're interested in using this solution, I recommend that you do the same — see if you like it."

"The management is simple in Pure Storage FlashArray."

More Everpure FlashArray pros

"The GUI is very straightforward and easy to use."

"Technical support is absolutely great."

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

"The stability of the solution is very good."

"It is consistently stable; haven't had a single issue with it."

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

"Rocketing IOPS results in performance we don't have to fixate on, so we can instead focus efforts on other layers in the stack, knowing that our SAN layer is lightning fast, with capacity to spare."

"Go with it. I tell people all the time they need to take a serious look at it."

More Kaminario K2 [EOL] pros

"The initial setup was easy, very simple, and we were up and running in less than an hour after it was racked and stacked."

"The product is easy to manage and deploy, it's got full API functionality and the performance is pretty steady."

"It's absolutely a consistently stable solution, with 100% up-time and no data loss at all, not even the slightest, delivering not only stability but also a lot of efficiency with the data storage."

"It's a very compact device. For a medium-sized business, it's very helpful because the device is efficient and very fast."

"The difference between SolidFire and other storage is that it is a stand alone storage; no one has that good storage software or that scalability and performance."

"Initial setup was very straightforward, easy."

"Being able to provide quality of service as promised."

"The simplicity of it."

More SolidFire pros

Cons

"The price of the solution can improve."

"I would like to see them develop the ability to integrate with more AWS services."

"We would like to be able to connect to data tape for backup, specifically to the LTO backups."

"I would like to see them lower the costs."

"The system has dual controllers but does not have a high level of resiliency built-in."

"Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE."

"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."

"I would like to see support for NVMe, end-to-end."

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."

"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."

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

"The interface look and feel could be improved."

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

"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."

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

"I would like them to come down in price."

More Kaminario K2 [EOL] cons

"We've had issues with the stability of our platform."

"The starting point of SolidFire is really a little bit on the expensive side, but from a scalability perspective, as a total cost of ownership, if you go for it then it's not so expensive."

"It would be good to provide administrative access at the root level to be able to do things with the system, if need be."

"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."

"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."

"So feature-wise, I would say more reporting tools that could be merged into it."

"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."

"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

"Our licensing is on a yearly basis. So, every year, we renew. We could do a three-year contract, but right now, we only do a one-year."

"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."

"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."

"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."

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

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

"Its price is almost double than any other flash storage solution."

More Everpure FlashArray pricing and cost advice

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

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

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

"The licensing is all-inclusive."

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

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

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

"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"

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

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

"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."

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