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.

Quotes from Members

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

Pros

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."

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

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

"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"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."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

More Pure FlashArray X NVMe pros

"The biggest trust element is people are very happy to depend on a Dell infrastructure."

"PowerStore's compression ratio is a valuable feature for our VMs because it gives us a lot back."

"You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature."

"The deduplication functionality provided by the solution is fairly good. The speed offered by the product is enough for our organization."

"The return on investment since switching to Dell PowerStore has been really good."

"The most valuable feature is the functionality of the integration between the storage and the domain."

"The beauty is the simplicity - customers can manage multiple workloads from a single dashboard with scale-out architecture."

"Typically, high-performance and high-availability features, such as application snapshots and remote and local replication, are highly valued."

More Dell PowerStore pros

"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."

"The most valuable features of IBM FlashSystem are performance and security."

"The ability to create LUNs and modify them are the most valuable features of this solution."

"The most valuable features are deduplication and compression."

"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."

"The storage system is one of the best in the world."

"No queuing and high ops, speed, and performance."

"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."

More IBM FlashSystem pros

Cons

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

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

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

"The software layer has to improve."

"There is room for improvement in the pricing of the product."

"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."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"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

"The customer support is slow and has room for improvement."

"I wish there were more options to fine-tune things. Some of the information requires deeper investigation to get data efficiency per data store."

"It needs more mature code."

"If I could improve Dell PowerStore in any way, I would enhance the socialization of the good skills this equipment has, improving communication with partners as the good features are inside Dell PowerStore, however, many customers don't know how powerful it is."

"The upgrades themselves are running fine, but after the upgrade is when we have a problem. With the update to 1.4, we had a head crash. They told us, 'This is a known issue. Please upgrade to 2.' We upgraded to 2 and, one week later they told us, 'Yeah, there are some issues in 2.0.0. You can lose data. Please upgrade to 2.0.1.' Overall, they need to make the system stable."

"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."

"The customer service and support are bad."

"The initial setup was a little bit cumbersome. We had a bit of an adoption process internally. It wasn't immediately straightforward on day one."

More Dell PowerStore cons

"The GUI needs some improvement."

"IBM FlashSystems is lagging in optimizing storage technologies."

"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."

"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."

"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."

"The product needs to improve their scalability."

"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."

"The interface of this solution could be improved."

More IBM FlashSystem cons

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."

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

"The product is expensive."

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

"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."

"As far as the licensing costs, everything is included in the license."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The solution is expensive."

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

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

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

"We are happy with the pricing that we get from Dell."

"The price of Dell EMC PowerStore could be better, it is a bit expensive."

"In the pricing and licensing department, the product is always too expensive."

"Dell PowerStore is not a cheap solution."

More Dell PowerStore pricing and cost advice

"The tool is cost-efficient."

"I would rate the pricing of this solution a four out of five."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

"This solution is expensive compared to other solutions."

"The pricing is competitive in our country."

"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."

"You purchase it as a bundle and the price is comparable."
