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.
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.
Yves Sandfort - PeerSpot reviewer
Gives us a lot of advantages when we need to expand resources
Stability can be improved. Adding all these new features is nice, but we are now at the level where most of the features you need in production are there. The stability is not from a day-to-day operations perspective, but more from a supportability perspective, because currently some of the support scenarios require you to completely evacuate hosts or the complete cluster. That sometimes can be a stretch. This would clearly be an improvement if the support teams were given additional tools to make that easier. Upgradability could be a bit easier sometimes. We are now where vSAN can be updated without ESXi, but there is still enough dependency. So that would be good if that actually would be uncoupled even more. Dashboards are there, and we use vROps as well. So, we have all the beauty of capacity planning and everything over there. That's not really something where we need a lot of other things.

Quotes from Members

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

Pros

"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."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The most valuable feature of this solution is reliability."
"The database workloads are pretty fast because I frequently move data from here to there."
"I appreciate the performance."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"We were able to integrate it very quickly with other solutions."
"We've never had an issue with storage."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"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."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"Scalability is good."
"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."
"When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes"
"Since the storage space is local to the hosts, it reduces the overall response time and improves the performance."
"The scalability is very good and the solution is stable and reliable."
"The product’s ecosystem is better than Nutanix’s."
"The lower skill cost of maintaining it meant that we could do more with the people that we had."
"The solution has high performance."
"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"The software layer has to improve."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"We need better data deduplication."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"In terms of what needs improvement, the dashboard and management could be simplified."
"I rate the scalability of Dell Unity XT a nine out of ten."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"Its replication technology could be better."
"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."
"Support Responsiveness & time to fix bugs should be improved."
"We are facing some problems with updates with the VMware vSAN. When we upgraded from version 6.5 to 7, we have been faced with many problems. They have been deploying many hotfixes for this version, and they need to continue to improve this version."
"I'd like to see better integration with the Update Manager, with respect to firmware updates for hardware."
"This product is very expensive."
"The server files are larger than before."
"As no product is 100% perfect, the price for VMware vSAN could still be improved, though it is good when compared to some of its competitors."
"VMware vSAN could improve by having better integration with other vendors and the storage is limited, I prefer it to the traditional storage."
"Only the stretched cluster requires a minor improvement."
"The UI falls short compared to other solutions. It needs some development to make it more user-friendly."
 

Pricing and Cost Advice

"The support cost per array is about $20,000 a year for 24/7 support."
"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 VMware, we pay $300,000 annually."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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 product is expensive."
"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The support you're getting with it is probably an underestimated value that comes with the box you're buying."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"The price is good for commercial grade storage arrays."
"The solution is relatively expensive compared to similar products."
"VMware is not a cost effective solution, especially if you have a Microsoft shop. In this case, you would have to purchase the VMware license when there are already Hyper-V solutions that could do it for much cheaper."
"I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license."
"The price of vSAN could be lower."
"The licenses are very expensive. The renewal of licenses has extra costs attached to it."
"The cost of the solution is high and if it could be reduced the customers would be very happy."
"This is a cost-effective product. It's a bit cheaper than the other solutions."
"In comparison with other solutions, such as HP or Cisco, I find the solution to be quite pricey."
