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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Quotes from Members

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

Pros

"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."
"The solution uses newer technology for deduplication and compression."
"Everything, especially the VMs inside, is pretty fast."
"The latency is good."
"It has good, reliable, fast storage."
"The most valuable feature of this solution is reliability."
"The solution is scalable."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"From a functionality perspective on cost-effectiveness, it is exceeding all expectations."
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"User friendly interface"
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"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."
"All-flash is a game changer. If you need performance, simple operations, and you plan to use it with VMware, it is a good choice."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"We particularly like the user interface on cloud IQ with this product."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The product's initial setup phase was good."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"The most valuable features of VMAX are its performance and GUI interface."
"It works very well."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
 

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"They could add more support for file storage and different types of storage."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Scalability for the 650F is good, but I was expecting a little bit more."
"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."
"The interface can be a little challenging for someone new."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"The uses of tools to communicate with EMC directly. With EMC, I am not able to connect and resolve issues without assistance, so they can't do unattended maintenance on devices, which would be a massive benefit if they could."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
"Improvements are needed in both partition recovery and scalability."
"There is room for improvement in the centralized administration."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability."
 

Pricing and Cost Advice

"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."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"With VMware, we pay $300,000 annually."
"It is priced at around or under $50,000."
"I rate Dell Unity XT’s pricing a nine out of ten."
"I liked the price point when we purchased it."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"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."
"The ROI is right where we need it to be. It's a reasonably priced array."
"The solution should be cheaper."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It is not a cheap product."
