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.

Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"The most valuable feature of this solution is reliability."
"The solution is scalable."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"I appreciate the performance."
"The database workloads are pretty fast because I frequently move data from here to there."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"For me, the most valuable feature is the ease of management."
"It is very stable."
"Dell Unity XT is a unified box, and it is integrated with VVOL, our software-defined storage."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"We are happy with the way we have Dell EMC Unity XT configured."
"Quick Snapshots and cloning are key features."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"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."
"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."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"There are some challenges with data encryption and reduction."
"In terms of what needs improvement, the dashboard and management could be simplified."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"I miss storage groups. Now, if I have to add a LUN to a cluster, multiple host, I have to know which host is in that cluster. I have to write it down and that makes it hard. In VNX and earlier, I could simply put a LUN on a storage group and every host in the group had the LUN. This lack bothers me a lot because it takes a lot of time and mistakes are made. Sometimes, a Hyper-V host gets a VMware LUN and vice-versa. Not good."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"Recently, they released products, sometimes without proper testing, it seems."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number."
"I would like to see better compression, better dedupe. It's not nearly as good as what is built into the XtremIO. I understand why that is the case, but if they can take some of that technology and leverage that a little bit better in the Unity array, that would be great."
"This solution would be improved with the addition of flexible raid volumes."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"The product is expensive."
"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."
"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."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"Obtaining a warranty is easy."
"Our costs are roughly $200,000 a year."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"The pricing of Dell Unity XT is good."
"The solution’s pricing is competitive."
"The support you're getting with it is probably an underestimated value that comes with the box you're buying."
