We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten.""We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency.""It is pretty much just plug and play. There is not that much to do with it. It is very easy to use.""It simplifies storage.""It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done.""Because we were able to afford to go all flash, we don't manage the tiers, we're not moving data up, and we're not waiting for overnight cycles.""Having an intuitive user interface to get things running is great.""The initial setup was straightforward in the way that it was a database vacuum storage."

More Pure Storage FlashArray Pros →

"It's unified, it does block and file, so that is pretty important to my customers who might have file servers around their environment. I can roll them all up into a single array, as well as provide block storage for them on one array.""Replication of the communication object (COB) scenarios""The most valuable feature is the performance. It's still an all-flash array at a good price point.""On the Data Domain side, the most attractive feature is the compression ratio, which none of the other products in the market are currently able to provide. On the Unity side, what customers mostly like is the availability guarantee.""Stable flash storage platform with good scalability, efficiency, and speed.""The product has helpful local technical support.""Integration is easy with this product.""The most valuable features are its performance and simplicity."

More Dell Unity XT Pros →

"The price of this solution is good.""The product’s quality of service guarantees the performance of each workload.""The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well.""The solution offers very good reliable systems and storage for our clients.""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.""Ability to cluster two storages together with HA availability.""The FlexClone feature is the solution's most valuable aspect.""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."

Cons
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there.""In the next release of this solution, we would like to see automated copy data management for SQL Server.""I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good.""I would rate this solution an eight. To make it a ten it would have to be a little cheaper.""Had some issues with Purity not being entirely compatible with VMware ESXi.""Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography.""Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve.""Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."

More Pure Storage FlashArray Cons →

"The upgrade process needs improvement. I should be able to swap it out, with zero downtime, with another array, down the road. I don't think Dell EMC has anything in the roadmap for this product line. I just don't want to have to deal with that anymore and all of our customers are pretty much the same.""Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication.""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.""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.""I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage.""The support portal needs fixing. Accessing a service request on the support portal seems to be a bit difficult, as opposed to just calling the 800 number.""Since Dell took over EMC, the support has been very bad. Before, the support was fine. Now, the support is slow or they don't react.""We'd like to see a cheaper version of an all-flash array in that footprint."

More Dell Unity XT Cons →

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five.""Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster.""Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed.""The solution should change the licensing model and allow customers to choose features based on their requirements.""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.""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 like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

  • "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.
