Featured Reviews

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 most valuable feature of this solution is reliability."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"Everything, especially the VMs inside, is pretty fast."
"The solution uses newer technology for deduplication and compression."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"It has benefited my organization because it has reduced time to insights."
"The database workloads are pretty fast because I frequently move data from here to there."
"The most valuable feature of this solution is its ease of use."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"We are happy with the way we have Dell EMC Unity XT configured."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"Quick Snapshots and cloning are key features."
"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."
"I like the ease of configuration, the quick setup and the fact that it seems to be hardened. We haven't had any issues with them. In terms of simplicity of ownership, once they're running you don't have to touch them. They're also simple to manage. We came from the VNXe 3200s so it's very similar."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"The solution's unified administration is its most valuable aspect."
"IOPS is comparatively best to run VDI solution."
"vSAN Health is a feature designed to monitor the health and performance of the vSAN environment. It's crucial for us and our customers to frequently check on this to ensure everything is operating smoothly."
"VMware vSAN is easy to implement in a VMware environment and it is not expensive."
"We've found the solution to be scalable."
"A one-stack solution from one vendor is the main benefit here."
"The setup is straightforward."
"Technical support is good."
 

Cons

"There are some challenges with data encryption and reduction."
"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."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"The software layer has to improve."
"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."
"There is room for improvement in the pricing of the product."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"I would like to see replication and DR features in the next release of this solution."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"It could be a little easier to attach it to a network file system."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"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."
"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."
"Sometimes the response time is higher than expected due to a lack of issues."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"Problems with I/O modules, with bugs that came out that really should have been caught before the product was released."
"he list of hardware supported should be increased in the future."
"I would like to be able to limit IOPS."
"Dedupe in non flash drives can be improved."
"This solution could be improved by having more than one controller for the environment. VMware depends on one controller for the whole environment, whereas Nutanix has one controller for each node. Because there is only one controller with VMware, if there was any drop, then the whole environment would stop working. In Nutanix, I have five nodes—there is one controller for each node and it depends on a virtual controller—so if the controller of any node is down, the whole environment will still work."
"VMware vSAN could improve by having better integration with other vendors and the storage is limited, I prefer it to the traditional storage."
"The price can be reduced. Small businesses cannot afford this solution."
"Improvements are also needed as per the customer's requirements."
"I would like to see some of the more traditional SAN functions that are out the now. I can list them: being able to Snapshot on the back-end, better de-dupe, and better compression. Those are the major ones."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"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."
"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."
"With VMware, we pay $300,000 annually."
"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."
"Our licensing fees are $500,000+ USD."
"The product is expensive."
"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."
"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 offers great pricing."
"The ROI is right where we need it to be. It's a reasonably priced array."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Our costs are roughly $200,000 a year."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"The pricing of Dell Unity XT is good."
"The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"The price of vSAN could be lower."
"It could be cheaper."
"We are using the VMware vSAN ROBO which allows us to have a maximum of 25 virtual machines. The approximate cost is €10,000 for a perpetual license."
"The licenses are very expensive. The renewal of licenses has extra costs attached to it."
"We have increased our user productivity."
"We did consider other hyperconverged solutions. It usually came down to price. vSan was the most cost effective thing."
"VMware vSAN is an expensive platform. We purchase its yearly license."
"The vSAN is somewhat expensive to license."
