We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"We put a fair amount of stress on it because we run sequel workloads and we run web applications where the same web files are hit over and over. We have had almost zero stability issues with that SAN, that has been really great for us.""It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use.""The solution offers amazing performance.""The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels.""Data deduplication features make it easier to manage storage and forecast growth.""Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations.""The security operating system is its most valuable feature because it's very simple, easy to use, and operate. You don't have to do very serious training to operate this equipment. It's user-friendly and pretty straightforward.""The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."

More Pure Storage FlashArray Pros →

"The ease of management and “user-friendly” management environment (GUI).""We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us.""I like Unity XT's software-defined storage. It's a new feature that isn't widely used yet, but customers are impressed with it.""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.""Its most valuable feature is the storage alarm.""I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product.""The most valuable features include snapshots, Thin Clones, and deduplication and compression.""One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."

More Dell Unity XT Pros →

"The product’s quality of service guarantees the performance of each workload.""We are satisfied with the stability.""Ability to cluster two storages together with HA availability.""Scalable and stable storage array.""The FlexClone feature is the solution's most valuable aspect.""Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems.""The price of this solution is good.""The most valuable feature of Lenovo ThinkSystem DM Series is its capability to tier to the cloud, such as Microsoft Azure or Amazon AWS. Additionally, the integration is good and they are user-friendly."

More Lenovo ThinkSystem DM Series Pros →

Cons
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features.""I would like to see data tiering to AWS.""We would like to be able to connect to data tape for backup, specifically to the LTO backups.""I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers.""Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations.""Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features.""They should work on their upgrades, they're not smooth.""The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."

More Pure Storage FlashArray Cons →

"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful.""The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market.""It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions.""This is a tier-three solution and it gives us what we need for archiving and backups.""My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be.""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.""Issues with slow responses from the support team.""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."

More Dell Unity XT Cons →

"The Lenovo ThinkSystem DM Series was very hard to configure. Installation of the product was very hard. These are its areas for improvement.""I would rate the support of Lenovo ThinkSystem DM Series a four out of five.""The licensing model needs to be revisited. It needs to be simplified.""Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed.""Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster.""I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers.""It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved.""This is an expensive solution."

  • "We have seen a reduction in total cost of ownership (TCO)."
  • "It is a cheaper solution."
  • "Pure Storage is all-flash, so this sometimes tends to make it a bit more expensive in the beginning."
  • More Pure Storage FlashArray Pricing and Cost Advice →

  • "The price is good for commercial grade storage arrays."
  • "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."
  • "Licensing is easy since all the software is included."
  • "This product is cheaper than the EMC VNX solution. It is good for small businesses."
  • "It is shipped with all licensed, included for this product range, no need to buy additional licenses"
  • "The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
  • "For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
  • "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."
  • More Dell Unity XT Pricing and Cost Advice →

  • "Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version.

    Overview

    Pure Storage FlashArray is the world’s first enterprise-class storage array that runs exclusively on the nonvolatile memory express (NVMe) protocol for memory access and storage. It represents a totally state-of-the-art type of storage technology. It offers users shared accelerated storage that delivers cutting-edge features in the realms of performance, simplicity, and consolidation. Pure Storage is fresh and modern today and will be for the next decade. Without forklift upgrades or planned downtime, Pure Storage takes the work out of storage ownership and delivers unprecedented customer satisfaction.

    Pure Storage FlashArray is built with simplicity and reliability in mind. The solution can be implemented and optimized in hours, as opposed to other similar solutions that can take days. It has no moving parts, which removes areas where it could potentially be vulnerable to suffering errors. It is highly stable and gives users the ability to manage system shutdowns in a way that  prevents data loss.

    Benefits of Pure Storage FlashArray

    Some of the benefits of using Pure Storage FlashArray include:

    • A much higher level of speed than similar pieces of technology. Pure Storage FlashArray maximizes the speed at which data can be transferred while at the same time minimizing system latencies that might slow the transfer down. Additionally, it offers users quick memory read and data access speeds.

    • A higher bang for your buck in terms of the storage capabilities you get for the money you pay. They are smaller in size than more standard storage technologies, but they offer flash memory, which enables users to store larger amounts of data than the current standard.

    Reviews from Real Users

    Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution. 

    PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."

    PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."

    Reviews from Real Users

    Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

    A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

    Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

    PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."

    To meet enterprise storage requirements, ThinkSystem All-Flash DM Series systems provide high performance, superior flexibility, and best-in-class data management. DM Series runs on ONTAP data management software, which gives customers unified storage across block-and-file workloads. It accelerates your business while improving the efficiency, flexibility, and reliability of your IT operations.
