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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"Overall stability is very good. It is a very stable solution."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"One of the best features is the support, which is excellent."
"The high availability of the product is the most valuable feature."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The database workloads are pretty fast because I frequently move data from here to there."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"We have Dell EMC engineers helping us out and doing some over the shoulder training. They are working with our customer right now doing data migration over to Unities from the legacy Oracle stuff. While they're doing this, they're showing people how the Unities work and the ins and outs of the software interface."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"We use it to implement all our VDI solutions."
"It is pretty stable. I like the stability, because everything works like it should. We made it all redundant. So, we don't have anything to worry about."
"Storage Snapshots have been really nice. They allow us to do backups without impacting our production workload that much. The scalability, the ability to add disks dynamically and adjust our workload as needed, has also been really helpful. That definitely makes my job easier. And the interface for managing Unity is very easy. The integrations between VMware Hypervisor and Dell EMC are top-notch, so it's been really easy to use and manage."
"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."
"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."
"Lenovo ThinkSystem DE Series is simple to use"
"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."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"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."
 

Cons

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's portfolio is minimal. It is expensive."
"It is on the expensive side."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"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)."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"A customer had to buy VMX because Unity didn't have WORM."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"The pre-sales technical support and technical engagement could be made better for this product."
"It would be great if the solution could integrate an NVMe disk."
"Its performance could be faster."
"The product could support advanced software integrations."
"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."
"Improvements can be made to the product's performance."
"There could be a snapshot feature in the solution."
"The features are limited."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
 

Pricing and Cost Advice

"The product is expensive."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"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."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"As far as the licensing costs, everything is included in the license."
"The support cost per array is about $20,000 a year for 24/7 support."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"The product’s pricing should be improved."
"It scales, but then you have to buy additional stuff."
"From a pricing perspective, this solution is comparable to others on the market."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"Pricing is as high as it has ever been for EMC."
"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."
"It is a good return on investment."
"It is an expensive solution."
"The pricing is fair and low compared to other products in this category."
"The solution's price could be better."
"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."
"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."
