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.

Quotes from Members

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

Pros

"The most valuable feature of this solution is its ease of use."

"The latency is good."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

"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."

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

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

"The solution uses newer technology for deduplication and compression."

"Overall stability is very good. It is a very stable solution."

More Pure FlashArray X NVMe pros

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

"They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time."

"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."

"IBM FlashSystem is flexible, quick, and has a solid design."

"The most valuable feature of the solution is compression."

"The solution is very easy to configure and use."

"Data deduplication is one of the most valuable features of this solution."

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

More IBM FlashSystem pros

"The FlexClone feature is the solution's most valuable aspect."

"The value we derive from using it is greater than other alternatives like HPE and Dell."

"The solution offers very good reliable systems and storage for our clients."

"Ability to cluster two storages together with HA availability."

"Last year, I did a DM Series installation with my colleague, and this installation was effortless because we had Lenovo support on the phone, so it was easy to get help if we had any problems."

"It has been a perfect fit for the workload that our customer is doing."

"One of the most valuable features of Lenovo ThinkSystem DM Series is the snapshot feature."

"The price of this solution is good."

More Lenovo ThinkSystem DM Series pros

Cons

"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 have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

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

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

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

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

"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."

"I would like to see replication and DR features in the next release of this solution."

More Pure FlashArray X NVMe cons

"The solution is not able to replicate data in one-to-many scenario."

"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."

"The interface could improve in IBM FlashSystem."

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

"It could be easier to implement."

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

"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 GUI needs some improvement."

More IBM FlashSystem cons

"Many people do not realize that Lenovo has a storage solution, so better marketing from the vendor is needed."

"It takes a very long time to enter the management console, as well as to restart the system, and these are things that should be improved."

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

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

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

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

"I would like Lenovo to add a feature like IBM Easy Tier to DM Series. This is a crucial feature for the customers."

"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."

More Lenovo ThinkSystem DM Series cons

Pricing and Cost Advice

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

"The licensing is on a yearly basis."

"Given its price, Pure is not the first option."

"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."

"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."

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

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"The price of IBM FlashSystem is reasonable."

"Overall the price of the solution is expensive and this includes the license."

"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."

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

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

"We have no issues with the price as it is very competitive."

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

"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."

More IBM FlashSystem pricing and cost advice

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

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

"The solution is highly-priced."

"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."
