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.

Ease of implementation and robust performance enhance multi-OEM support experience

We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

Good price-performance ratio, provides simplified provisioning and management

We use this solution for provisioning and management The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption. The exterior display needs to be improved. Sorry, I like the blue lights the competition has, but maybe we can see green led lights…

Quotes from Members

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

Pros

"It’s easy to set up and support is excellent."

"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."

"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."

"Having an intuitive user interface to get things running is great."

"After installing Pure, the processes that would take 40 minutes to two hours to complete are now done in five minutes."

"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."

"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."

More Everpure FlashArray pros

"The most valuable feature is the fast cache with functionality rewrite."

"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."

"The solution is so easy to manage that I forget it is there."

"The benefits are the simplicity, flexibility and the ease of integration between the Unity platform and VMware, for example, and Microsoft platforms; the integration tools and the simplicity of management."

"Delivers High IOPS, but more important, low latency as this is the most important part for our usage."

"Because I always need to trouble shooting for IOPS & database (DB) performance issues. I can quickly focus on what is part of the issue. I can decrease downtime and can plan next year's extended capacity budget."

"It has a very intuitive web console that runs in HTML5 and makes navigation and administration fairly easy."

"The first time we got a Unity was last year, we started deploying some of our file system data into it, and we have been seeing a significant improvement, not just in the way that we take Snaps, but with the recoveries as well."

More Dell Unity XT pros

"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."

"This solution had the best cost and it was easy to work with the Vendor."

Cons

"Price is about the only thing that's wrong with it."

"The file functionality could be better."

"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."

"In Pure Storage FlashArray, the area with room for improvement is local MFA login."

"The price should be lower."

"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."

"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."

"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."

More Everpure FlashArray cons

"I'm not sure if it has a single pane of glass management console. That would be something we would like to see."

"We realized that we were barely getting a 12 percent compression offset, not the 50 percent, and this came about the time of the merger."

"To the best of my knowledge, migration from VNX to Unity without VPLEX/RecoverPoint is not available right now."

"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."

"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."

"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."

"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud."

"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."

More Dell Unity XT cons

"The exterior display needs to be improved."

Pricing and Cost Advice

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."

"The solution is expensive."

"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."

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

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

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

"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."

"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."

More Everpure FlashArray pricing and cost advice

"It is an average priced solution."

"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."

"Obtaining a warranty is easy."

"The solution’s pricing is competitive."

"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."

"The solution is very expensive."

"It is priced at around or under $50,000."

"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
