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

"Technical support is excellent. I've had very good responses from technical support. We had a couple of cases where we needed support. Some of the communications were purely over email and some has been an actual call to the service desk."
"Its ease of use is a very big thing for our customers; it's easy to set up and easy to maintain, and the support is automated, which is very good."
"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"For an organization, it can take storage from 40 terabytes down to five terabytes."
"This solution has helped my organization by cutting down on provisioning time; I used to have to provision a VM and it would take ten minutes, now, it takes thirty seconds."
"I would definitely suggest this solution to a colleague because of the ease of use."
"The most valuable feature is how it simplifies the management of the SAN."
"It's a great return on investment, based on the mission."
"I like that the performance is very good."
"This is a very stable platform, so far zero issues."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"It will certainly help us scale bigger."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"The product has met all our expectations."
"We were able to retire all our VNX systems and reduce the footprint in the data center, and the Unity systems can scale up quickly, so we use less space in the data center if we employ more Unity systems than the old VNX systems."
"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. It integrates pretty well."
"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."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"Lenovo ThinkSystem DE Series is simple to use"
 

Cons

"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level."
"I would like to have support available in Spanish."
"The integration capabilities could be improved."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"With the introduction of Albireo technology and 81x data de-duplication reduction, Pure Storage better start looking at more effective de-duplication techniques."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"Organizations with security concerns that prevent cloud utilization would benefit from a wider range of instruments available for offline operation. Currently, the limited selection of on-premise instruments hinders Pure Storage FlashArray's ability to compete effectively with other vendors."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react."
"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."
"In some countries, spare part availability is an issue for us."
"Dell Unity XT’s price needs improvement."
"The virtual appliance is limited to 4TB in storage."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"It would be useful to have structured solutions replicated to other sites."
"The solution could be more scalable, although it suits our present needs."
"Improvements can be made to the product's performance."
"Usually, when a part fails, we have to replace it and it takes a while."
"Improvements can be made to the product's performance."
"The product could support advanced software integrations."
"There could be a snapshot feature in the solution."
"The features are limited."
 

Pricing and Cost Advice

"The price of Pure Storage FlashArray is expensive."
"When I last looked, the prices were reasonable, and we could get an excellent array for about $60,000."
"The price was more favorable than Dell EMC."
"There are no licensing fees aside from the support."
"It's priced higher than the market."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"It's expensive, but you get what you pay for."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"The ROI is right where we need it to be. It's a reasonably priced array."
"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."
"While it has a good price to start, they could always make it cheaper."
"Go with the virtual appliance versus the hardware."
"We purchased a five-year warranty."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"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."
"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 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 best thing about this solution is its price, which reduces our costs."
"The solution's price could be better."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"The pricing for this solution is good compared to HP or Dell EMC."
