Cons
"It is a bit expensive.""In the next version of this program, I would like to see increased security, higher encryption, and faster throughput.""It goes at about 95 percent, so we have had some performance issues. It is hard to clear them.""Its price needs improvement. Its price is almost double than any other flash storage solution.""The GUI could improve, it could be more intuitive. There is hidden functionality.""The price could be better.""A minor issue that comes to mind is that, every once in a while, a hard drive will go bad.""The time-to-market could be better at times, but I think that's true for all vendors of hardware."

More Pure Storage FlashArray Cons →

"Its performance could be faster.""Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution.""In the next release, I would like to see more functionality. But, again, it is an entry-level product.""ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec.""The features are limited.""In the next release, I would like to see support for Hyper-converged infrastructure.""Improvements can be made to the product's performance.""The solution could be more scalable, although it suits our present needs."

More Lenovo ThinkSystem DE Series Cons →

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers.""The solution should change the licensing model and allow customers to choose features based on their requirements.""Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed.""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.""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.""This is an expensive solution."

    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."

    The DE All-Flash Series delivers the performance of more than 2,000 15k rpm HDDs, yet requires only 2% of the rack space, power, and cooling. Because it consumes 98% less space and power, DE Series can significantly improve the overall efficiency of your IT operations while continuing to meet your performance requirements.

    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.
