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

"The dashboard is nice. It is easy to manage compared to other storage solutions such as Dell EMC."

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

"Both the ease of setup and the reliability of the array makes it quite simple to manage for the customer."

"Their REST API is wonderful, well-documented, and easy to use."

"Even if they weren't one of the fastest arrays in the entire industry, I would use them for their support model and ease of use."

"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."

"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."

"The technical support is very good."

More Everpure FlashArray pros

"Technical support is absolutely great."

"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."

"Kaminario allowed us a solid state solution with marginal incremental cost."

"Provisioning large numbers of virtual desktops has sped up considerably."

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

"Logic/software management"

"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."

"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."

More Kaminario K2 [EOL] pros

"It really helped us not only in delivering the service levels to our users, but also automating 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."

"It is very easy to scale up SolidFire."

"Each time I have been in contact with technical support, it has been proactive."

"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 stable and performs very well without any bugs."

"With a SolidFire I think that problem goes away."

"The most valuable feature is the performance, as well as how you manage performance on the system."

More SolidFire pros

Cons

"Awareness about Pure Storage needs to increase. Currently, people mostly think of Dell and NetApp when it comes to storage."

"The price could be better."

"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."

"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."

"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."

"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."

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

"Pure Storage FlashArray could improve by being more secure."

More Everpure FlashArray cons

"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."

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

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

"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."

"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."

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

"The interface look and feel could be improved."

More Kaminario K2 [EOL] cons

"One of the challenges we faced while using SolidFire was that the product line that we were using in our company was discontinued."

"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 integration with the cloud, number one. Being able to spin SolidFire in the cloud."

"The scalability of HCI or SolidFire as such isn't a concern, but when you compare it to PowerMax or NetApp AFF series devices, scalability is a concern because it's only the drives that are connected to the nodes. We don't have any shelf connectivity."

"For example, the ease of use with the reporting. Right now it's not impossible, but you have to know Sequel. It's a little time consuming to get those customized reports in there."

"For people using FC SAN, SolidFire is not an option because of the interface."

"The level of monitoring could be better."

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

More SolidFire cons

Pricing and Cost Advice

"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."

"Pure Storage FlashArray's pricing is very competitive."

"The price of the solution is not expensive."

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

"The best features come included without any additional cost."

"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."

"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."

"We purchased a license to use this solution and we pay for the storage ourselves."

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."

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

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

"The licensing is all-inclusive."

"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."

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

"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."

"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"

"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."

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