Sales Manager at Multicomputos PR

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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

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

"The database workloads are pretty fast because I frequently move data from here to there."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The initial setup was extremely simple and straightforward."

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

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

More Pure FlashArray X NVMe pros

"The valuable feature is autoscalling."

"The most valuable feature in demand is virtualization and its support storage of virtualization features."

"IBM products at the enterprise level are stable solutions, with a score of nine out of ten for stability."

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

"I like most of the features. Its speed, performance, and availability are valuable. We are implementing the data reduction technology the most."

"The price-performance ratio is most valuable."

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

"The installation is nice and easy."

More IBM FlashSystem pros

"Lenovo ThinkSystem DE Series is simple to use"

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"The solution is very easy to set up."

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

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

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"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."

"The solution's initial setup process is easy."

More Lenovo ThinkSystem DE Series pros

Cons

"The software layer has to improve."

"It is on the expensive side."

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

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

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

"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."

"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."

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

More Pure FlashArray X NVMe cons

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

"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."

"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."

"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."

"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."

"IBM FlashSystems is lagging in optimizing storage technologies."

"The ease of installation should be improved. We had issues with the configuration model."

"The Data Reduction Pools (DRP) support could be better."

More IBM FlashSystem cons

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

"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"Improvements can be made to the product's performance."

"The features are limited."

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

"The product could support advanced software integrations."

"Its performance could be faster."

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."

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

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

"The product is expensive."

"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."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"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."

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

"I price of IBM FlashSystem is reasonable and competitive."

"This solution is expensive compared to other solutions."

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

"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."

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

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

More IBM FlashSystem pricing and cost advice

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

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

"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."

"The best thing about this solution is its price, which reduces our costs."

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

"It is an expensive solution."

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

ThinkSystem DE Series

Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.

IBM

The DE All-Flash Series delivers the performance of more than 2,000 15k rpm HDDs, yet requires only 2% of the rack space, power, and cooling. Because it consumes 98% less space and power, DE Series can significantly improve the overall efficiency of your IT operations while continuing to meet your performance requirements.
