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.

"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."

"IBM FlashSystem has been stable in our operations."

"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."

"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."

"The Flash core models offer amazing performance."

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

More IBM FlashSystem pros

"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 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."

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

"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."

"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."

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

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

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

More Lenovo ThinkSystem DE Series pros

Cons

"We need better data deduplication."

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

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"It is on the expensive side."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

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

"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

"In the next release having the next level of high-speed performance would be great."

"The solution is not easy to use and could improve."

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

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."

"IBM FlashSystem 5300 needs improvement in its deduplication and compression features."

"The product needs to improve their scalability."

More IBM FlashSystem cons

"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."

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

"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."

"Its performance could be faster."

"The features are limited."

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

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

More Lenovo ThinkSystem DE Series cons

Pricing and Cost Advice

"The product is expensive."

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

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

"The licensing is on a yearly basis."

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

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"I would rate the pricing of this solution a four out of five."

"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."

"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 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."

"The solution requires a license and could be less expensive."

"The pricing is competitive in our country."

"I find the pricing of the solution to be very reasonable."

"Its price is very good."

More IBM FlashSystem pricing and cost advice

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

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

"It is an expensive solution."

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

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

"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 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.
