Here are some excerpts of what they said:
Pros
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration.""The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster.""For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space.""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to use.""We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us.""The speed is the most valuable feature of this solution.""The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side.""The most valuable features are the replication of data and the continuous snapshot that we can take from the disc."

"Data Compression: Up to 80% space reduction in the database""High performance and ease-of-management are the most valuable features.""It's very fast. We were seeing read latencies of less than one millisecond. It is robust.""It provides a combination of all the protocols that you need, without losing deduplication and compression.""It performed great originally, and when it performed great, it was awesome.""It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment.""The initial setup is straightforward.""EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"The most valuable feature of the Lenovo ThinkSystem DM Series is its ability to store data well.""We are satisfied with the stability.""Ability to cluster two storages together with HA availability.""The FlexClone feature is the solution's most valuable aspect.""Scalable and stable storage array.""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.""The price of this solution is good.""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."

Cons
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable.""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.""We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array.""The number of Filesystems is limited, which it is not on the EMC VNX.""I would like to see data tiering to AWS.""It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups.""In some cases, we get into very in-depth conversations around movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that.""We haven't seen ROI."

More Pure Storage FlashArray Cons →

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors.""It's somewhat scalable, but maybe not so much as some of the competition.""In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation.""Snapshots are not as easy to access as on a NetApp device.""It only keeps one hour of real-time data without the ability to do deep analysis of each element.""They need to offer better integration for a virtual platform to enable you to create hyper-converged solution.""Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible.""Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

More DDN IntelliFlash Cons →

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features.""This is an expensive solution.""The licensing model needs to be revisited. It needs to be simplified.""I would rate the support of Lenovo ThinkSystem DM Series a four out of five.""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.""Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster.""The solution should change the licensing model and allow customers to choose features based on their requirements."

Pricing and Cost Advice
  • "We feel that the pricing is fair and the licensing process was easy for both."
  • "There is always room for negotiation."
  • "The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
  • "It is a more expensive solution, but it is worth it. You are getting what you paid for."
  • "For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
  • "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."

  • "I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."
  • "I think we pay around 100 grand per year for three arrays or four arrays."
  • More DDN IntelliFlash 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. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
  • "The price of the Lenovo ThinkSystem DM Series is good."
  • "The solution is highly-priced."

    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."

    Western Digital through its IntelliFlash arrays delivers high-performance storage with a complete range of features and connectivity options, including inline compression and deduplication, application and VM consistent snapshots, replication, RAID, data encryption, VMware vCenter integration, and multi-protocol support for SAN (FC, iSCSI) and NAS (NFS, SMBv3). IntelliFlash arrays deliver high availability through dualredundant and hot-swappable components, active/active or active/passive controllers, non-disruptive software upgrades, eMLC flash, and proactive cloud-based monitoring, analytics, and intelligence. A RESTful API provides scripted or programmatic control.

    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.
