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.

Quotes from Members

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

Pros

"Everpure FlashArray is probably not cheap storage, but it provides great performance, scalability, and everything a customer needs."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"We saw a vast improvement when we switched over to using the Pure Storage model over the XtremIO."
"I can personally state that the Pure Storage Flash Systems are the best built and Pure has the utmost professional customer care."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The most valuable features are the ease of use and support."
"I like the performance. Performance-wise, it accommodates the needs of highly-critical servers. It is reliable."
"Our clients see a reduction in total cost of ownership by around 40%."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"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."
"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."
"Its quick integration with VMware. The ability to stand up a data store in one place, where you don't have to go and rescan for the data store through the vCenter Client, as well as SMB shares. This ended up being a big selling point for us."
"The most valuable features of this product are its reliable storage and its archiving feature."
"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is simple to use"
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"The solution is very easy to set up."
"The solution's initial setup process is easy."
 

Cons

"The solution could improve by having a multi-tenant feature."
"I want to improve the overall service level of the solution."
"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"In the next release I would like to see integration into other third-party player providers like Google."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"The price of Pure Storage FlashArray could be better."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"Some of the other data-reduction technologies, like deduplication, are not to the level of other competitors and what their products provide."
"On the data domains - for the Unity product, but specifically for data domain - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"The product could support advanced software integrations."
"It would be useful to have structured solutions replicated to other sites."
"It is really entry-level. In the next release, I would like to see more functionality."
"The solution could be more scalable, although it suits our present needs."
 

Pricing and Cost Advice

"There are no fees for licensing. The hardware is paid for only once."
"I would prefer that they lower their pricing."
"The price of Pure Storage FlashArray is expensive."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"FlashArray is expensive, but the quality justifies the price."
"We feel that the pricing is fair and the licensing process was easy for both."
"I would rate it a seven out of ten for pricing. It could be improved."
"Pure came in at a better price point than EMC and performed better than Compellent."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise. Huawei and Lenovo are very price competitive. Looking at the price point for a country like Sri Lanka, where we have a very low economy, I think you need to look at a pricing mechanism that is a bit more flexible."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"The pricing of Dell Unity XT is good."
"The price is very reasonable."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"The ROI is right where we need it to be. It's a reasonably priced array."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"We have a five-year contract for providing support."
"The pricing is fair and low compared to other products in this category."
"The solution's price could be better."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The best thing about this solution is its price, which reduces our costs."
