Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

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 biggest lesson that I have learned from using Pure FlashArray is that it's user-friendly, easy to manage, and very flexible."
"The stability of Pure Storage is very very good."
"I would definitely suggest this solution to a colleague because of the ease of use."
"We have perfect run through times and latency."
"The best feature is consistently lower latency, even when IOPS crank up to over 75K, and the product maintains submillisecond response time, which is incredible."
"Technical support is good."
"We currently have four Pure Storage FlashArray boxes, and all the storage boxes are on an Evergreen subscription model where we receive the latest hardware and features without any cost in a completely non-intrusive task."
"It has improved my organization in the way that now we have lower latency, we get fewer complaints from customers, and we see a constant response time."
"DEV/UAT refresh periods reduced from hours or longer to under five minutes."
"The solution's most valuable features are the inline data reduction and deduplication."
"Dell XtremIO provides great performance."
"The Metro clustering and solid-state performance, are the most valuable features of this solution."
"Very good IOPS performance"
"The solution's most valuable feature is its high performance."
"I rate Dell XtremIO at eight out of ten. It is a product I would recommend to companies where data performance, scalability, and security are highly important due to its beneficial features."
"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, and the dedupe and compression that this array provides both do a superb job."
"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 higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"They should work on their upgrades, they're not smooth."
"There are a lot of things to improve."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"I would love to see a true one click upgrade solution."
"The interface lacks the same level of control as some other arrays I've used."
"I am not too impressed with XtremeIO because we had a major failure."
"We had issues at the data corruption level, which resulted in multiple X-Brick failures."
"It needs a way to determine the deduplication of each LUN and what the impact would be if we were to move data from one LUN to another."
"I would like to see more scalability."
"The management should be improved and the GUI interface could be better and easier."
"The technical support was poor, even during the port or 2TB limit."
"The earlier version before Version 4.0 had several stability issues."
"Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience."
"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 price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"I'm good with the licensing. Of course, pricing can always be less... It's actually not a bad pricing model, considering I don't have to rip-and-replace."
"Because the price is a bit higher than other products, the data reduction equalizes the price with amount of the data reduction."
"Dell and Pure Storage offer competitive pricing, but Pure Storage might have a slight advantage."
"We have seen a reduction in TCO."
"The pricing is very attractive and it delivers performance for the money."
"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."
"This solution is a little bit pricey."
"It is great when a product can deliver high-end performance capabilities while offering a very competitive price point."
"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."
"Pricing and licensing are in line with other products from other manufacturers. You get what you pay for."
"With some workloads that benefit from compression and deduplication, costs are actually better than some tier 2 subsystems (while latency remains <1ms)."
"It is costly but worth it."
"The price of the solution should be reduced. The price matches the price of a VMAX service but it does not have the capability of a VMAX service. However, the prices of Dell EMC XtremIO can be reduceable."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
"We acquired VAST Data as a one-time, capital purchase."
