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.

Has improved data reduction and snapshot efficiency while supporting critical workloads

There are some areas that could be improved with Dell XtremIO. The API to connect with command line or to see performance very clearly could be enhanced, similar to how NetApp works with Grafana and NetApp monitor, which shows you a comprehensive view of the whole picture. The snapshot functionality could work more similarly to Snap Center. If I want to see all the VCenter with the VM, I think it needs the API for this. I do see big differences between Dell and other products. NetApp works very closely with VCenter, and Hitachi also integrates well, but Dell is not very clear and does not proceed well with VCenter integration with Dell. It needs the API, and I need to see all the snapshots. If I want to restore a VM from only a few directories or a few files that I need to restore, it is very difficult. I do see some differences in licensing. For the last few years, the Dell EMC price is acceptable. A few years ago, Dell EMC was expensive, approximately 20 percent more than NetApp. Right now the budget between EMC and NetApp is very closely aligned. Regarding the installation process and deployment of Dell XtremIO, I notice that in Israel, a lot of professional services and engineers who work with Dell EMC have moved to another storage company. I do not know why. Dell EMC does not have enough engineers, system engineers, or professional services engineers to provide service to the old clients, similar to how NetApp or Hitachi do. I think Dell XtremIO is between easy and complicated to deploy; it gives you the whole picture, but I need to go closely to VCenter to connect to VCenter to see the snapshot and to see performance with more dashboards of performance. I also need to connect the switch fiber channel to see all zoning to give me more flexibility to install or configure fiber channel or to see the performance of the fiber channels. I think there should be some fiber channel disconnect adapter or better troubleshooting from hardware for errors.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

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

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

"Overall stability is very good. It is a very stable solution."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"The solution is very straightforward to set up."

"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 Everpure FlashArray X NVMe pros

"Very good IOPS performance"

"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."

"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."

"Deduplication and cloning capability"

"The most valuable features include the easy manageability of snapshots and its excellent performance in large-scale workloads."

"The program is very stable."

"The most valuable features are: complete performance and ease of use."

"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."

More Dell XtremIO pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

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

"There are some challenges with data encryption and reduction."

"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."

"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."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"The software layer has to improve."

More Everpure FlashArray X NVMe cons

"Scalability is something that can be improved because there is an issue when it comes to mixing versions."

"XtremIO is coming to its end of life."

"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."

"The physical architecture could use some higher levels of redundancy."

"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."

"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."

"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."

"The interface could be simplified for beginners to ease the configuration of special objects in the system."

More Dell XtremIO cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"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."

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

"Our licensing fees are $500,000+ USD."

"The licensing is on a yearly basis."

"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."

"The support cost per array is about $20,000 a year for 24/7 support."

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

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"There are costs in addition to the standard licensing fees."

"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."

"You can get a two-year or three-year license for the tool. You can also opt for a perpetual-based licensing model, which can be renewed on a yearly or two-year basis."

"The initial purchase price was good but when you need to upgrade, it's a different story."

"Don’t buy this array. You’re paying for loads of magic beans, since it’s mediocre at best for a platform in a rapidly growing field. Look instead at Pure Storage or something with variable block deduplication. You’ll end up spending less and getting a better product with actual support."

"It is expensive if you need to increase scalability."

"The license for XtremIO is in the box, so you don't have to buy anything."

"It is great when a product can deliver high-end performance capabilities while offering a very competitive price point."

More Dell XtremIO pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
