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.

Gives us the foundation to grow efficiently
We're a manufacturer. All of our ERP software is dependent upon fast performance and connection to this hardware. So when there was an issue years ago when something was wrong or slow, that prompted us to say, "Can we check storage? Can we check the network?" Ever since we've gone up to all-flash FAS systems, there's never any questions about performance when it comes to storage. There's been a huge leap from spinning disks to SSDs. I'm hoping with the next update, we'll go to NVMe and we'll have similar experiences. Last year, we refreshed the SAN at our headquarters. We signed a Keystone agreement with the ability to pay for storage as a service at an excellent price point yet still have the hardware on-prem. I manage the hardware, and, for me, it's the best of both worlds. We've just come up with a situation where, finally, after some time, we're going to need to buy some additional storage. In previous situations like this, it usually meant the purchase of an additional shelf at a large price. Now we have Keystone, and we're locked in at that price per tebibyte. We just have to say that we want to add 25 tebibytes and they take care of it. It's worked out really well. We work ISO 27001 certified. Since I manage the enterprise storage, we use SnapMirror, and we're currently using Veeam for backups. Thanks to what this tool provides, we are able to get through that portion of our certification without a problem. No changes, no rectifying. It's very slick. Our company's goals include maintaining a level of consistency. We're never going to be on the bleeding edge. We're never going to have the super fastest abilities. We want something that works, is easier for us to manage, and has a better growth path. For us, in the past, in the need for additional disk space, if we didn't do the sizing right in the first place, buying additional disks was incredibly expensive. Now, with Keystone, that's no longer an issue, and that's what we like.

Quotes from Members

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

Pros

"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."
"The latency is good."
"I appreciate the performance."
"Technical support has been helpful and responsive."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The database workloads are pretty fast because I frequently move data from here to there."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"It has good performance."
"The Snapshot feature is key."
"The solution is so easy to manage that I forget it is there."
"It is scalable. We can add additional tools if we need to expand it."
"It's the simplicity part of it. It's the ease of management, it's the call home, the CloudIQ functionality. It's all built in. I think Dell EMC has put a lot of thought into it."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"MetroCluster is the best product on the market. It synchronizes the storage. NetApp's update packages are a huge advantage because the firmware and server updates are in one package."
"The amazing thing is that whenever we have come up with an issue where we need to get something done, and it wasn't necessarily available, they could do things for us, usually within the next revision of the software."
"NetApp support is fantastic."
"NetApp's inline deduplication and compression are unmatched compared to other vendors."
"NetApp's hot and cold storage are its most valuable features. We currently use the A series. Immutable snapshots are another advanced security feature that is positive."
"We've reduced downtime. Without all of NetApp's benefits, we would have had to reconfigure parts of storage that would have required downtime. We have dramatically reduced our downtime through successive generations of NetApp, allowing us to get Five 9s availability."
"NetApp AFF A-Series is faster and more robust compared to the all-flash storage of NetApp."
"NetApp helps us get the fastest output."
 

Cons

"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's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Maybe the price can be reduced since the solution is very expensive."
"There is room for improvement in the pricing of the product."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"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."
"There's always room for improvement with the UI. That can be a little cumbersome at times."
"We would like to see more advanced integration capability added to this solution."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"The initial installation is straightforward and took approximately one hour. However, the full process was not as simple as IBM."
"The reporting should be better. In other systems, you can create many different kinds of reports but this is not the case with Dell."
"​Improve the interface and provide more management capability."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"Scalability of this solution could be improved."
"We have several problems with the limitations of NetApp systems in terms of volume shares. We have a brick in a 700 or a controller, and we sometimes make small volumes, but Kubernetes container volumes don't allow us."
"I really don't have a lot of complaints. In the past, there were issues, however, they've really done a great job of reaching out."
"NetApp is shifting to the cloud and adopting AI, but it is not improving its core technology to deliver faster storage. We're still waiting to see if it improves speed with solutions like the 90 series."
"It would be helpful if our partner organized a yearly session with my team to discuss the new feature sets on our current solutions and other ways NetApp can help us. Perhaps we are missing some information to help us make the right decision."
"Pricing could always be lower."
"The solution's ransomware protection could be improved."
"NetApp AFF A-Series should work on cost. The solutions, especially enterprise-level storage, should be more affordable to improve their appeal to businesses."
 

Pricing and Cost Advice

"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."
"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."
"With VMware, we pay $300,000 annually."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"Given its price, Pure is not the first option."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"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."
"Pricing is as high as it has ever been for EMC."
"This solution is a good price for what you get."
"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."
