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.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

A versatile storage solution suitable for various workloads in cloud environments providing scalable architecture, granular Quality of Service and consistent performance
The most significant benefit lies in its exceptional performance, driven by its Flash-based architecture. This enhances routing speed and, consequently, database performance. The provisioning process is efficient and doesn't demand higher latency, ensuring optimal data transfer performance which is particularly valuable for tasks like data mining, where quick results are essential.

Quotes from Members

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

Pros

"One of the best features is the support, which is excellent."
"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."
"Everything, especially the VMs inside, is pretty fast."
"The solution is scalable."
"The most valuable feature of this solution is its ease of use."
"The most valuable feature of this solution is reliability."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The high availability of the product is the most valuable feature."
"You can add volume and it's automatically registered in VMware."
"Replication of the communication object (COB) scenarios"
"There are also DR and data protection functions that we found in the new Unity, now that we are stepping up from VNX and other storage appliances, that we've started implementing."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing."
"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"It's a very compact device. For a medium-sized business, it's very helpful because the device is efficient and very fast."
"If you buy the solution for its specific purpose it will work well."
"Templates are already predefined for it. If you're coding it up, it will take two days. You can pick up a template right there from the API, and it just works for you. Implementation done in 10 minutes."
"The dashboard is such that you don't need to be a storage expert to administer it."
"It is very easy to scale up SolidFire."
"SolidFire has seamless performance for the nodes and extensions. I also like the tool’s scalability. The product’s performance does not get affected when we scale either up or down. This is not the case with other products."
"We can just buy them, scale them as we need on demand, and we don't have to spend so many front end cycles on designing the architecture."
"It's got full API functionality and the performance is pretty steady."
 

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
"They could add more support for file storage and different types of storage."
"The tool's portfolio is minimal. It is expensive."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"It is on the expensive side."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."
"I would like the UI to look better."
"You can't use every feature, because it costs in performance. Therefore, you have to choose which features to use to achieve a better environment. That is why customers do not use every feature in Unity."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"Scalability of this solution could be improved."
"Though it is a stable solution, its users may face some security issues at times...The security provided by the solution is one area that can be improved."
"I would like to see integration with the cloud, number one. Being able to spin SolidFire in the cloud."
"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."
"A little better segregation of the multi-tenancy. Right now, it's just VLAN-specific, that's all you can do."
"I think there is room for improvement needed with its storage capability. A bigger node is needed."
"So feature-wise, I would say more reporting tools that could be merged into it."
"They could do a file-based NAS: SolidFire NAS-based. It's probably not its niche, but that is our direction, not to use block, and it's block. Solid state block is what it is."
"We had some false positives, power supplies failing, and that's really been about it. We had a couple of glitches during some upgrade processes but nothing that was really concerning to us."
 

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."
"With VMware, we pay $300,000 annually."
"As far as the licensing costs, everything is included in the license."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The licensing is on a yearly basis."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"Go with the virtual appliance versus the hardware."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"It scales, but then you have to buy additional stuff."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"While it has a good price to start, they could always make it cheaper."
"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."
"Based on what I heard from other people, its price was on the higher side."
"The price of this solution is more expensive than others."
"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."
"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"
