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.

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

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

More Pure FlashArray X NVMe pros

"It's very easy to manage."

"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."

"The installation is nice and easy."

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

"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."

"IBM FlashSystem is a stable solution."

"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."

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

More IBM FlashSystem pros

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

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

"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."

"Lenovo ThinkSystem DE Series is simple to use"

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

Cons

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

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

"Maybe the price can be reduced since the solution is very expensive."

"In the future, I would like to see integration with enterprise backup systems."

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

More Pure FlashArray X NVMe cons

"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."

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

"The GUI needs some improvement."

"The price is very costly."

"The solution's pricing is a bit high so there is room for improvement."

"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."

"The data reduction pool feature sucks and is not recommended for use with heavy workloads."

"The product needs to improve their scalability."

More IBM FlashSystem cons

"Its performance could be faster."

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

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

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

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"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."

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

"The features are limited."

Pricing and Cost Advice

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

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

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

"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."

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

"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."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"Among IBM, Dell EMC, and Pure Storage, IBM is the cheapest. The price is also based on our location, the size of our entity, and our regular annual purchases from them. We are a very big IBM customer, so we normally get very high discounts. We are not a big customer of Pure Storage. We don't buy that much from Pure Storage per year. Everything is included in the price. There is no extra license for different functions."

"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."

"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 pricing is competitive in our country."

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

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

More IBM FlashSystem pricing and cost advice

"The solution's price could be better."

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

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

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

"It is an expensive solution."

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

"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."

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.
