Helps to save money and resources with the data compression feature

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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Offers cost-effective storage for small companies with budget constraints

IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.

Quotes from Members

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

Pros

"What I really like about this program, is that it is easy to use and easy to configurate."

"On a scale of one to ten, I rate Pure FlashArray as ten."

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

"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."

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

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

"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."

"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."

More Pure FlashArray X NVMe pros

"We use IntelliFlash products for larger environments, like Qatar Airways."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"It performed great originally, and when it performed great, it was awesome."

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"The initial setup is straightforward."

"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."

"High performance and ease-of-management are the most valuable features."

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"

More DDN IntelliFlash pros

"FlashSystem offers proven technology in a compact package."

"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."

"The speed, performance, and stability are the best features of IBM FlashSystem."

"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."

"Flash disk with Easy Tier option"

"It's very easy to manage."

"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."

"The all-flash storage has tier replication capabilities."

More IBM FlashSystem pros

Cons

"There are some challenges with data encryption and reduction."

"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."

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"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."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

"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."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

More Pure FlashArray X NVMe cons

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"It's somewhat scalable, but maybe not so much as some of the competition."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."

"Snapshots are not as easy to access as on a NetApp device."

"In future releases, I look forward to more AI features."

More DDN IntelliFlash cons

"When you provision a datastore auto-format takes a long time"

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

"The GUI needs some improvement."

"I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution."

"The interface of this solution could be improved."

"The solution is not easy to use and could improve."

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"Cloud file sharing is an area that needs improvement."

More IBM FlashSystem cons

Pricing and Cost Advice

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

"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."

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

"The licensing is on a yearly basis."

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"The pricing is competitive in our country."

"The solution requires a license and could be less expensive."

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

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

"The pricing is reasonable."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

"The price is a little bit high so is rated a six out of ten."

"This is an expensive product and if the price were reduced it would be better."
