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.

Used for VMs with replication a feature, but need upgraded SSDs
We use this solution. I configured and updated it. Of course, I was also a user of applications that store data on that storage. We already have an SSD solution. So, rather than planning to go with an SSD solution, we are focusing on expanding it. If a company wants to deploy something new, it should choose a product with SSD, and NVMe disks. Overall, I rate the solution a six out of ten.

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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"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."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The solution is very straightforward to set up."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"To be programmatically administered is huge, it is one of the key features that we like about it."
"Replication of the communication object (COB) scenarios"
"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."
"The most valuable features are the NAS features and NetApp's excellent support."
"The product is flexible."
"Has rock solid reliability and is easy to use."
"Compression of the backup Oracle by RMAN on NFS saves space 5:1."
"Fast Snapshots"
"The replication feature protects us from data loss."
"It's enabled us to allow admins across the IT organization to more easily manage their own subset of data within our organization."
"It's a stable product. No issues there."
 

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"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."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"We integrated it with vSphere but that integration was "iffy". It was okay but we had a few challenges with it."
"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."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"It needs more functionality and the ability to move across more landscapes."
"Needs to improve the adaptive storage quality of service."
"It was not possible to have a custom user inside ONTAP without the delete permission to delete the volume. We wanted others to be able to create a SnapMirror and volume, but have no volume deletion permission. In the newest version, it seems to already be in place, but there was a bug enabling this one in older versions 9.11, 9.10, or earlier."
"The solution can improve on the replication features."
"Technical support needs to be improved, as there are no longer partners in our country."
"Installation of the additional switches and ETP could be improved."
"The only downside is in ease in management; it is not easy to use."
"We have some experience with older equipment end-of-life. For example, when warranty support stops or updates stop – it can be frustrating. Not all clients can buy a new filer every year or two, and NetApp ending support a bit quickly can be a concern."
"I would like to see less latency and higher IOPS."
 

Pricing and Cost Advice

"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."
"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."
"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."
"As far as the licensing costs, everything is included in the license."
"The product is expensive."
"The licensing is on a yearly basis."
"The support cost per array is about $20,000 a year for 24/7 support."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"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."
"It is priced at around or under $50,000."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"We purchased a five-year warranty."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"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."
"The pricing of NetApp FAS Series is not cheap, but in comparison to other vendors, NetApp FAS Series is affordable because they also have deduplication, compression, and inline compression. They focus on storage only, which is really good; it works."
"I've sold arrays for as little $20,000 USD and as high as $300,000 USD."
"The NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."
"The pricing of NetApp FAS Series is reasonable for its performance."
"The solution’s cost is reasonable."
"It is a one-time license charge for NetApp FAS Series to run and we pay annually for upgrades and support."
"The tool is expensive."
"The licensing cost is on yearly basis."
