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.

I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

Quotes from Members

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

Pros

"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 feature is its speed."
"The most valuable feature is its data reduction."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"The biggest return on investment for us is not having to do a swap out of the arrays every five years."
"It releases those to new teams within minutes at a very small storage cost amount."
"Remote assist is a valuable feature that supports customers and engineers in troubleshooting and resolving issues, allowing for easy problem identification and repair."
"If you factor in the ease in terms of operations, as well as the cost of the array compared to other solid state arrays, it becomes a clear positive for Pure Storage."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example, and for our purposes, we find Unity simple to use."
"User friendly interface"
"The most valuable feature is the ease of integrating it into our current environment."
"Since we have deployed, this has easily saved us close to about $300,000 easily."
"I like the idea that it can compress and dedupe inline. That is quite a stunning feature for mid-range customers."
"It is easy to scale, maintain, and manage."
"The ease of management and “user-friendly” management environment (GUI)."
"The solution's initial setup process is easy."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"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

"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"Enhanced documentation and beginner-friendly guidelines would benefit users with less configuration experience."
"A minor issue that comes to mind is that, every once in a while, a hard drive will go bad."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"Reports of performance and LUN utilization could be improved."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"The technical support is okay, but could be improved."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"Dell EMC Unity XT has some scalability issues which they need to address."
"I would like better monitoring capabilities: more historical data with more insight into the performance for the database. We now use a separate tool for it. Therefore, it would be nice if we could have that straight from the tool."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to enhanced."
"There is a lot of room for improvement on the support side, because of the response time."
"If you compare it with VMAX, where we communicate with the box through Solutions Enabler and there are a lot of commands and a lot of flexibility, the command line for Unity needs to be enhanced."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"It is really entry-level. In the next release, I would like to see more functionality."
"The product could support advanced software integrations."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
"Improvements can be made to the product's performance."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Its performance could be faster."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"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."
"It is cheaper than NetApp."
"You get what you pay for. It is expensive, but it really works."
"Pure came in at a better price point than EMC and performed better than Compellent."
"There are no fees for licensing. The hardware is paid for only once."
"Its price is almost double than any other flash storage solution."
"We are finding the TCO of flash to be lower than SSD implementations."
"The solution should be cheaper."
"We purchased a five-year warranty."
"Pricing is as high as it has ever been for EMC."
"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."
"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."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"This solution offers great pricing."
"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."
"The pricing for this solution is good compared to HP or Dell EMC."
"It is an expensive solution."
"The pricing is fair and low compared to other products in this category."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have a five-year contract for providing support."
"The best thing about this solution is its price, which reduces our costs."
