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.

Quotes from Members

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

Pros

"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."

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

"It is simple, powerful, and a beautiful solution."

"Everpure FlashArray has positively impacted my organization by increasing our agility and the ability to run our environment at high speeds due to the flash storage."

"If I want a product which has reliability and high speed, and Pure Storage is the first name that comes out of my mouth."

"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."

"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."

"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."

More Everpure FlashArray pros

"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."

"We have had no stability issues with the product, including when adding replication on the fly, customer installed code updates, and customer installed DAEs."

"As far as cost is concerned, it does great deduplication, and from a storage perspective, we save money being able to dedupe right on the disk."

"Fully automated storage tiering (FAST) cache capabilities allows some FLASH drives to be used to improve the overall performance and reduce the cost of the array versus an all flash or old style spinning disk array."

"We currently have two Dell EMC Unities going. One of them at our primary on-premise DR site. They communicate with each other. If we ever have to failover, it is right there and ready."

"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."

"The product has helpful local technical support."

"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."

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

"The technical support is okay, but could be improved."

"The best way to improve Pure Storage FlashArray is the active DR because that can get very confusing, especially when you're trying to test a failover and replicate back; better instructions on how to do that would help because we actually lost an entire volume when we were testing out some stuff as the fingerprint got reinitialized, and when you replicated back, it didn't know about that volume, causing a failure in that process."

"CIFS and SMB Shares cannot be mounted directly."

"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."

"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."

"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."

"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."

"The product could improve by providing the capability to support NAS storage – CIFS and NFS."

More Everpure FlashArray cons

"The payment account area."

"In terms of what could be improved, I would say its capacity and its connection."

"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."

"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."

"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise."

"We have only used this solution for less than one year so I don't have any improvements suggestions yet."

"The storage processors have less port expansion than previous high-end VNX arrays. Data compression is only available in all-flash pools."

"For the integration of the VPLEX function for Cross IDC structure, they should integrate the function into the SP controller."

More Dell Unity XT cons

"The exterior display needs to be improved."

Pricing and Cost Advice

"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."

"The solution is expensive."

"For us, as the customer, it reduced the price of the management."

"The price was more favorable than Dell EMC."

"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 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."

"Cost-wise, it's been very effective."

"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."

More Everpure FlashArray pricing and cost advice

"The pricing of Dell Unity XT is good."

"Compression is making a difference towards the amount of hardware that we need to purchase."

"Our CAPEX was close to $42,000 and operating costs are below $1000."

"The price of Dell Unity XT could improve. However, it is a one-time purchase."

"This solution is a good price for what you get."

"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."

"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."

"While it has a good price to start, they could always make it cheaper."
