Pure FlashArray X NVMe

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.

Integrated AI and clustering enhance storage operations effectively

I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.

"The product is reliable and stable."

"The use of NVMe is notable, and the speed and performance it provides are commendable."

"As a primary storage, it has all the features that our customers need, with only minor tweaks or enhancements needed here and there."

"The most valuable feature of Dell PowerStore is its easy-to-use feature, specifically the simplicity."

"After implementing Dell PowerStore storage, the performance became exceptional, and customers started to notice improvements in system access."

"On a scale of one to ten, I rate Dell PowerStore a ten out of ten."

More IBM FlashSystem pros

Cons

"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."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"The UI for this solution needs to be improved."

"They could add more support for file storage and different types of storage."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"We need better data deduplication."

More Pure FlashArray X NVMe cons

"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."

"To improve, they could enhance their attitude and empathy by putting themselves in the shoes of the other person when providing support."

"Having all the services consolidated makes it hard to scale."

"It needs more mature code."

"The support team should have more people with experience in the solution's installation process, as it is one of the areas where I see certain shortcomings."

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

"In future updates, I would like to see more AI functionality plus a good integration with OneDrive."

"One suggestion for improvement would be related to volume management by both controllers. Currently, a volume is managed by a single controller, with alternate controllers managing different volumes based on load distribution. For example, if volume one is managed by controller one, volume two will be managed by controller two. In other vendors' solutions, both controllers participate in the I/Os. It would be more efficient if the volumes were controlled by both controllers in an active-active configuration."

More Dell PowerStore cons

"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."

"The solution is quite expensive. That's one of the downsides to using it."

"IBM FlashSystem 5300 needs improvement in its deduplication and compression features."

"The pricing needs to be more competitive."

"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."

"I would like to see bigger modules."

"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."

"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."

Pricing and Cost Advice

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

"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."

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."

"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."

"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."

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

"The product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"Pricing depends on the model and negotiation. Sometimes we manage to get good discounts, sometimes not."

"The pricing is good. There's no need to pay for a license; it's all-inclusive."

"The software features are included in the pricing without any additional purchase requirements."

"We purchased it with a five-year warranty."

"Dell PowerStore is affordable and the license is just a face license which is great."

"The price is high compared to the Tunisian market."

"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

More Dell PowerStore pricing and cost advice

"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."

"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."

"The solution has good pricing, but it is not cheaper."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."

"The total storage capacity vs price is still quite high for the IBM Flash Array."

"The pricing is competitive in our country."

"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
