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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"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."

"What I really like about this program, is that it is easy to use and easy to configurate."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

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

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

More Pure FlashArray X NVMe pros

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

"The Metro clustering and solid-state performance, are the most valuable features of this solution."

"The speed is extremely valuable."

"The speed and scalability of Dell XtremIO are significant features that improve data storage management."

"Dell XtremIO is good for databases and huge workloads."

"It is scalable."

"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."

"The performance is good, which is important."

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

"The software layer has to improve."

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

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

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

"We need better data deduplication."

"I'd like to see the product implement active replication for vehicles such as VMware."

"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."

More Pure FlashArray X NVMe cons

"The product could be improved by reducing the pricing and having better organization in their technical support team."

"I would like to see the ease of deployment and built-in Metro clustering."

"I believe having more replication options comparatively to VMAX (other than RecoverPoint) would be great."

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

"If you are looking at flash storage solutions, XtremIO doesn't offer any unique features. Most of my customers are migrating their workload from XtremIO to other formats because of this."

"When we upgraded the capacity from five to ten TB, the price of the disks was high."

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

"The product is highly expensive. Additionally, there is a significant lack of training, support documents, and forums available for Dell XtremIO, making troubleshooting difficult for third-party individuals."

More Dell XtremIO cons

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

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

Pricing and Cost Advice

"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."

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

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

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

"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."

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

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"XtremIO is an all-flash array, which means it's a costly solution. When compared with general mid-range storage solutions, this is more expensive. As far as I know, there are no additional costs besides the license."

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

"The licensing cost is on a yearly subscription basis, which can be expensive but is necessary for ongoing support and services. The pricing could be improved to make it more accessible."

"Dell XtremIO's price is affordable and I would rate it a five out of ten."

"It's not cheap, but it absolutely gets the job done. I don't have any real comment regarding licensing specifically."

"This is the best flash array on the market for high-end workloads, so expect to pay for that. But the support subscription cost is fixed for seven years, which made it easier for us to plan on the maintenance costs."

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

"XtremIO is pretty straightforward about pricing. However, you need to look at your data so you can estimate, with the advice of DEL EMC, what data reduction ratio you will reach. In our case, a 3:1 reduction ration gave us a positive case compared to other storage arrays."

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."
