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.

"The initial setup is straightforward and can be done in an hour and a half by one person."

"The performance is very good and we use this product to enhance our core system."

"The performance of the solution is noteworthy."

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

"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."

"User friendly management interface."

"The valuable features of IBM FlashSystem include flash copy mapping, which is a procedure to collect instant point-in-time data for testing real data."

More IBM FlashSystem pros

"We have been working with the solution for around a year and so far it has shown itself to be stable."

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"Lenovo ThinkSystem DE Series is simple to use"

"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."

More Lenovo ThinkSystem DE Series pros

Cons

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

"It is on the expensive side."

"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."

"In terms of what needs improvement, the dashboard and management could be simplified."

"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 portfolio is minimal. It is expensive."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"We would like to see VNC integration or be able to use Pure Storage with VNC."

More Pure FlashArray X NVMe cons

"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."

"IBM FlashSystems is lagging in optimizing storage technologies."

"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."

"We had issues when attempting to do a flash, we hope to resolve it soon."

"Sometimes the performance is effective but it gets resolved in the process."

"I would like to see an improvement in the handling of large amounts of rights."

"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."

"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."

More IBM FlashSystem cons

"It would be useful to have structured solutions replicated to other sites."

"The solution could be more scalable, although it suits our present needs."

"In the next release, I would like to see support for Hyper-converged infrastructure."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."

"The product could support advanced software integrations."

"The features are limited."

"There could be a snapshot feature in the solution."

Pricing and Cost Advice

"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."

"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."

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

"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."

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

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

"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..."

"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."

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."

"The tool is cost-efficient."

"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."

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

"The cost of the IBM FlashSystem is lower than the HPE solution."

More IBM FlashSystem pricing and cost advice

"We have a five-year contract for providing support."

"It is an expensive solution."

"The solution's price could be better."

"For an all-flash setup, the cost is around $20,000 for a decent configuration."

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"The pricing for this solution is good compared to HP or Dell EMC."

"The pricing is fair and low compared to other products in this category."
