Featured Reviews

Jaehoon Oh

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.

A solution with a simple configuration and good stability but it's quite expensive

Access to technical support should be improved for our region. Technical support is good, but they're very hard to access. When we have a problem with this storage, it's usually related to a very bad configuration. All-Flash Storage is very, very expensive. They are important solutions so I don't really have any ideas about how to rectify this. The device could use better monitoring tools.

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

"It has benefited my organization because it has reduced time to insights."

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

"Everything, especially the VMs inside, is pretty fast."

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

"Technical support has been helpful and responsive."

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

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

"I appreciate the performance."

More Pure FlashArray X NVMe pros

"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."

"The speed and, for us in particular in what we're doing, the data de-duplication."

"Scale out is a differentiator for them, especially in the enterprise market. It's key for a lot of customers."

"Implementation of the solution is very simple."

"Inline compression"

"The GUI is very straightforward and easy to use."

"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."

"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."

More Kaminario K2 [EOL] pros

"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."

"Greater IOPS, speed, it's all-flash. So seeing that everything is going to all-flash, all SSDs, SolidFire fits right in there with the emerging trend in IT."

"If we get complaints about any kind of performance metric issues, whether it's storage related or something on the virtual side, we use it to pinpoint what the actual issue is."

"I would say in terms of architecture and in terms of functionality, the product is quite good."

"The system efficiency is excellent overall."

"The most valuable feature of this solution is its scalability."

"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."

"Overall performance of the solution."

More SolidFire pros

Cons

"The software layer has to improve."

"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."

"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 tool's pricing is higher than competitors."

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

"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."

More Pure FlashArray X NVMe cons

"A single pane of glass to monitor/manage multiple arrays would be helpful."

"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."

"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."

"I would like them to improve the look of the product’s external casing and shelves."

"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."

"The management graphical interface needs more improvement."

"The front panel of the drive shelf doesn't always seat firmly."

"The interface look and feel could be improved."

More Kaminario K2 [EOL] cons

"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."

"We have a large fiber channel infrastructure, and that's one area that we haven't seen implemented in SolidFire, its more iSCSI."

"I think there is room for improvement needed with its storage capability. A bigger node is needed."

"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 are looking for, potentially, on the Active IQ reporting side, to do reporting based on the datastore. Right now, I can report on the whole SolidFire, or I can report on just a certain datastore or a volume. I'd like to take all of my VDI infrastructure, which as an example would be multiple datastores."

"So feature-wise, I would say more reporting tools that could be merged into it."

"There is room for improvement with a focus on creating a centralized storage system, functioning similar to AWS."

"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

"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."

"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 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."

"The licensing is on a yearly basis."

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

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

"The product is expensive."

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

More Pure FlashArray X NVMe pricing and cost advice

"The licensing is all-inclusive."

"I would like them to come down in price. It is as expensive as EMC, Hitachi, and other major vendors."

"The "extra" costs associated with features and options that are available off the shelf with Kaminario, make their value proposition extremely competitive."

"Kaminario is very competitive on price. They also have a pay per TB model."

"Licensing is very straightforward. The cost was considerably lower than other products we looked at."

"All features are provided in the licensing. The cost of Kaminario was less than the cost of a hybrid array."

"The Kaminario setup is simple and there are no hidden licensing fees so this area is a relief."

"Based on what I heard from other people, its price was on the higher side."

"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"

"The price of this solution is more expensive than others."

"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."
