Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

Quotes from Members

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

Pros

"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"One of the best features is the support, which is excellent."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"It is completely reliable, the plugins for it are quite mature, and I don't really have any issues with the interactions with vSphere, they all work as intended."
"Replication and ease of storage setup for block LUN’s and VMware."
"Quick Snapshots and cloning are key features."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The NAS capability is mainly what we're looking for from this product, and being able to recover fast in DR."
"I really like the storage system."
"Stability has been pretty rock solid for us."
"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."
"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."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"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."
"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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
 

Cons

"We have run into a couple of instances recently where we are running out of space."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"The tool's pricing is higher than competitors."
"They could add more support for file storage and different types of storage."
"The software layer has to improve."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I would like them to continue to build on the solution and expand on the functionality, like replication."
"The pricing is a bit higher than expected."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products."
"Perhaps the user interface could be better."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"There is room for improvement in manufacturing."
"It would be useful to have structured solutions replicated to other sites."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"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."
"Improvements can be made to the product's performance."
"While it is a reliable product, it could be improved. It would be useful to have structured solutions replicated to other sites."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"You can not buy a lot of options for these devices. There are a lot of things that it does not do."
 

Pricing and Cost Advice

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"Given its price, Pure is not the first option."
"The product is expensive."
"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"As far as the licensing costs, everything is included in the license."
"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 price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"We have to apply for a license for each system."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"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."
"Our costs are roughly $200,000 a year."
"I liked the price point when we purchased it."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"It is an expensive solution."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The solution's price could be better."
"The pricing is fair and low compared to other products in this category."
"We have a five-year contract for providing support."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The best thing about this solution is its price, which reduces our costs."
"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."
