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.

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.

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

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

"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 are flexibility and performance."

"IBM's technical support do excellent work."

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

"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

"Scalable and stable storage array."

More Lenovo ThinkSystem DM Series pros

Cons

"It is on the expensive side."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"Adding some functions to the product would be beneficial."

"The tool's pricing is higher than competitors."

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

"We need better data deduplication."

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

More Pure FlashArray X NVMe cons

"This solution could be improved by offering greater amounts of storage."

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

"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."

"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."

"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."

"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 should improve its data reduction development."

"The support could improve by allowing you to speak to someone when you call rather than them calling you back. However, once we do have contact with one of their technicians they are excellent."

More IBM FlashSystem cons

"There might be improvements needed in drive throughput as disk speed has been a limitation on Windows servers."

"Lenovo ThinkSystem DM Series could improve by having a snapshot feature. Additionally, there can be other features added to help restore the data faster."

"The solution should change the licensing model and allow customers to choose features based on their requirements."

"The licensing model needs to be revisited. It needs to be simplified."

"This is an expensive solution."

"The tool's pricing is high."

"The solution needs a simpler licensing theme around the DM series. The problem is if you only need one of the features, you still have to buy the whole thing. The licensing needs to be more granular or flexible so you have the option to only license FlexCone or Inline Compression features."

"I would rate the support of Lenovo ThinkSystem DM Series a four out of five."

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."

"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."

"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."

"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."

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

"The licensing is on a yearly basis."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"They've been much more aggressive in the last five, six years than they were before that."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"The pricing is competitive in our country."

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

"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 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."

"If five is a good price and one is a high price, I would rate the price a two or three out of five."

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

More IBM FlashSystem pricing and cost advice

"The solution's pricing is similar to Dell and HPE."

"The solution is highly-priced."

"The price of the Lenovo ThinkSystem DM Series is good."

"Lenovo offers two software tiers for the DM Series: basic and premium. If you need more features like the MetroCluster, you must buy the premium version. You can stick to the basic software if you don't need MetroCluster or features like asynchronous replication. That makes DM Series a little cheaper."
