Syed Habib - PeerSpot reviewer
Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.
Eugene Hemphill - PeerSpot reviewer
Helps to save money and resources with the data compression feature
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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Quotes from Members

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

Pros

"The all-flash feature is really boosting up the VMware. It is helping our virtual machines to perform better."
"The technical support is very professional and provides quick responses."
"Stable flash storage platform with good scalability, efficiency, and speed."
"The Snapshot feature is key."
"For me, the most valuable feature is the ease of management."
"The solution overall has high performance."
"The multiprotocol support. It's supporting NFS, fiber channel, CIFS, and these kinds of things. The multiprotocol is very attractive."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"It has good, reliable, fast storage."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"The most valuable feature of this solution is reliability."
"The solution uses newer technology for deduplication and compression."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
 

Cons

"It is missing some features, like deduplication."
"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."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Scalability for the 650F is good, but I was expecting a little bit more."
"The interface can be a little challenging for someone new."
"It needs more functionality and the ability to move across more landscapes."
"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."
"It would be great if the solution could integrate an NVMe disk."
"We need better data deduplication."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The tool's pricing is higher than competitors."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In the future, I would like to see integration with enterprise backup systems."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's portfolio is minimal. It is expensive."
 

Pricing and Cost Advice

"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."
"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 of Dell Unity XT could improve. However, it is a one-time purchase."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"This solution is a good price for what you get."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"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."
"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."
"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."
"Our licensing fees are $500,000+ USD."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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 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."
