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

"After moving to Pure Storage, I have noticed that our databases are considerably faster and our performance has improved by at least four times."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"It's extremely stable and has good performance."
"The white glove customer service that I get is their greatest value."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"Having an intuitive user interface to get things running is great."
"Cuts VM deployment down to seconds and cuts latency under MS with amazing performance and very stable operation with no worries about how much it can handle."
"At this point, I don't know anything that they could provide in a better way."
"The most valuable features of this product are its reliable storage and its archiving feature."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"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."
"Dell EMC Unity XT is cheap and deep storage."
"The All-Flash models are intuitive and easy to work with, in addition to providing high IOPS with low latency to support Business Critical applications."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Its initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills; it does not have all the functionality of the DM but it is acceptable, it does its task, and it integrates pretty well."
 

Cons

"We haven't seen ROI yet."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"There are a lot of things to improve."
"I wish they could collaborate more with the other vendors internally, instead of us opening cases with Cisco, HPE, VMware, etc."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"Most of our upgrades have not been as smooth as they should have been."
"In terms of improvement, Everpure FlashArray could have more attractive UI/UX design compared to other solutions."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot; with the Unity 300, this is not possible."
"I rate the scalability of Dell Unity XT a nine out of ten."
"Support and licensing are big things, in the end, that needs improvement."
"There is room for improvement in manufacturing."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"The solution could be more scalable, although it suits our present needs."
"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."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"In the next release, I would like to see support for Hyper-converged infrastructure."
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray could always improve. They are still more expensive than some alternative offerings. Cost is always a concern and when there is a battle they tend to be more expensive."
"There is always room for negotiation."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"Pure Storage has not helped to reduce our HANA licensing costs."
"There is an annual or perpetual license required for this solution."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"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."

"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"I rate Dell Unity XT’s pricing a nine out of ten."
"Our costs are roughly $200,000 a year."
"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 pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"The solution is very expensive."
"The solution is very expensive."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"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."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The pricing is fair and low compared to other products in this category."
"The solution's price could be better."
"It is an expensive solution."
