Chief Technology Officer at Lambda256

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.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Quotes from Members

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

Pros

"The most valuable feature of this solution is its ease of use."

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

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"The solution is scalable."

"The latency is good."

"The most valuable features of this solution are its ease of use and performance."

"The solution uses newer technology for deduplication and compression."

More Pure FlashArray X NVMe pros

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"High performance and ease-of-management are the most valuable features."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

"Data Compression: Up to 80% space reduction in the database"

"It performed great originally, and when it performed great, it was awesome."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

More DDN IntelliFlash 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."

"The solution is very easy to set up."

"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."

"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."

"Its initial setup process is easy."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"Lenovo ThinkSystem DE Series is simple to use"

More Lenovo ThinkSystem DE Series pros

Cons

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"The UI for this solution needs to be improved."

"Maybe the price can be reduced since the solution is very expensive."

"They could add more support for file storage and different types of storage."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"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."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

More Pure FlashArray X NVMe cons

"In future releases, I look forward to more AI features."

"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."

"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."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"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."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"It's somewhat scalable, but maybe not so much as some of the competition."

More DDN IntelliFlash cons

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"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."

"Improvements can be made to the product's performance."

"The features are limited."

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"It would be useful to have structured solutions replicated to other sites."

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

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

Pricing and Cost Advice

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

"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."

"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 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 product is expensive."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

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

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"The solution's price could be better."

"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."

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

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

"It is an expensive solution."

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

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

ThinkSystem DE Series

Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

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.

DataDirect Networks

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.
