Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Quotes from Members

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

Pros

"The solution is very straightforward to set up."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"It has benefited my organization because it has reduced time to insights."

"The high availability of the product is the most valuable feature."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"Technical support has been helpful and responsive."

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

More Pure FlashArray X NVMe pros

"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"Lenovo ThinkSystem DE Series is simple to use"

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

"The solution's initial setup process is easy."

More Lenovo ThinkSystem DE Series pros

"The most valuable feature is Safe Mode."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The product is scalable and easy to expand."

"It performs well and it is also very fast."

"The most valuable feature of this solution is performance."

More Pure Storage FlashBlade pros

Cons

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"The tool's portfolio is minimal. It is expensive."

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"I would like to see replication and DR features in the next release of this solution."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

More Pure FlashArray X NVMe cons

"The features are limited."

"The solution could be more scalable, although it suits our present needs."

"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 type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"In the next release, I would like to see support for Hyper-converged infrastructure."

"The product could support advanced software integrations."

"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."

More Lenovo ThinkSystem DE Series cons

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."

"The features provided for SMB customers are limited."

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"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."

"Given its price, Pure is not the first option."

"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."

"With VMware, we pay $300,000 annually."

"We pay approximately $50,000 USD per year in licensing fees."

"As far as the licensing costs, everything is included in the license."

More Pure FlashArray X NVMe pricing and cost advice

"We have a five-year contract for providing support."

"It is an expensive solution."

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The best thing about this solution is its price, which reduces our costs."

"The solution's price could be better."

"The pricing for this solution is good compared to HP or Dell EMC."

"The pricing is fair and low compared to other products in this category."

More Lenovo ThinkSystem DE Series pricing and cost advice

"The pricing for FlashBlade is between cheap and moderate."

"The price of this solution could be made more affordable."

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"I rate the tool's pricing a seven to eight out of ten."

"The price is a little high."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"Licensing fees are paid yearly."

"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
