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

"Quick Snapshots and cloning are key features."
"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."
"For our customers, it's the simplicity of it. They find it easy to use, along with the added features, the dynamic volumes."
"I have had no problem at all. I think this is one of the most important things. It is very good. Maintaining it and deploying updates require very low maintenance. We haven't had problems. We had to replace a couple of disks in all these years, but it was pretty straightforward."
"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"Its quick integration with VMware. The ability to stand up a data store in one place, where you don't have to go and rescan for the data store through the vCenter Client, as well as SMB shares. This ended up being a big selling point for us."
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"The most valuable feature of this solution is its ease of use."
"I appreciate the performance."
"The high availability of the product is the most valuable feature."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"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."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
 

Cons

"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"Include cloud-based replication for blocks"
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"They should update to the cloud."
"It isn't easy to find trusted partners for the product. The solution has issues with mid-level storage and does not come with enterprise storage."
"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 portfolio is minimal. It is expensive."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"I'd like to see the product implement active replication for vehicles such as VMware."
"There are some challenges with data encryption and reduction."
"Adding some functions to the product would be beneficial."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
 

Pricing and Cost Advice

"Our CAPEX was close to $42,000 and operating costs are below $1000."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"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."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"We purchased a five-year warranty."
"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."
"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 product is expensive."
"The support cost per array is about $20,000 a year for 24/7 support."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"Our licensing fees are $500,000+ USD."
"As far as the licensing costs, everything is included in the license."
"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."
