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

"The solution has probably reduced my power use substantially."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"I cannot imagine my workflow without Everpure FlashArray because I do not have any other type of storage in use."
"Very efficient storage"
"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"Reliability and performance are its most valuable feature."
"What I like most about this solution, is the speed, resiliency and scalability."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"The most valuable feature is the ease of integrating it into our current environment."
"It saves us time, it does not require a lot of admin from us."
"I cannot stress enough how simple and easy it is to set up and use and manage."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"Stable flash storage platform with good scalability, efficiency, and speed."
"Unity provides a complete storage solution for VMware on a Wintel Windows box for various applications, such as SQL or Patron Databases."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"The solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"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."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"Its initial setup process is easy."
"Lenovo ThinkSystem DE Series is simple to use"
"We have had a very good experience with customer service and support, as they answer questions very fast and resolve our issues."
 

Cons

"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"There are many features which need to be added, particularly on the replication side."
"The only issue is the pricing. Because we have competition, our customers always take another brand and say they can save their investment."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"There are a lot of things to improve."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"The system has dual controllers but does not have a high level of resiliency built-in."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"The user interface could use improvement."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"Having used EMC products for more than 15 years, this is the first product in that time that I could find nothing to like."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"There could always be improvements to the UI."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"The pricing is a bit higher than expected."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"It is really entry-level. In the next release, I would like to see more functionality."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The solution could be more scalable, although it suits our present needs."
"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."
"Scalability on rack-mount servers is not as good as with Blade servers."
"Its performance could be faster."
 

Pricing and Cost Advice

"The cost has room for improvement."
"The license for Pure Storage FlashArray includes the support and there are no additional payments that are needed. This is not an inexpensive solution, you need to understand the value of your data before you use a backup solution."
"We have seen a reduction in total cost of ownership."
"We are finding the TCO of flash to be lower than SSD implementations."
"It's a good price point and it's a solid product for the price."
"The cost has room for improvement."
"It's expensive, but you get what you pay for."
"The pricing is very attractive and it delivers performance for the money."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"The solution is very expensive."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"While it has a good price to start, they could always make it cheaper."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"Go with the virtual appliance versus the hardware."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The best thing about this solution is its price, which reduces our costs."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"The pricing is fair and low compared to other products in this category."
"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."
"It is an expensive solution."
"The solution's price could be better."
