Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.
Gustavo Rosello - PeerSpot reviewer
Provides solid hardware and ROI to users
Companies or groups of business units are growing fast. We have perhaps between four and five more people than what it was two years ago, so the systems are increasing, and now we are working with RPA in some of our processes for automation, especially wherever it is mandatory in the financial branch, like a common investment fund and the investment in action or where there are other products. Our market is directly related to small business. We are working with companies where data translation is needed or where invoices, specifically credit invoices, the negotiation of cheques, or a doc that shows receipt of money, which you can sell at a future date. We have a sub-warehouse that has a back office in the cloud to use all operations related to creditors so that the company can increase its share in the markets. I think that we may need something on-premises in the future. The trends indicate that users are returning to on-premises systems because of the high cost of public clouds. We are looking for a better data center. In Argentina, hardware costs are high, but now, it is a great investment. We are slowly planning to expand the tool. In the USA, when it comes to object-first devices, there is a cost of 48,000 USD for 128 TB, but in Argentina, the cost is 64,000 USD for 84 TB. In Argentina, we have a lot of taxes, and the government is in the process of reducing these taxes, but now we have a situation associated with our economy. Out of 100 companies, only two are seeking employees. We are waiting for the recovery of the economy, but everything here is expensive apart from the salaries.

Quotes from Members

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

Pros

"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The compression and deduplication features are the most valuable."
"Virtualization of external storage, while adding cache and speed to the external storage."
"Over the years, it has become increasingly user-friendly."
"Flash disk with Easy Tier option"
"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 valuable feature is autoscalling."
"We are a 100% satisfied with the stability of the solution."
"I like that it's stable, and I am satisfied with it. We have had some issues, but that is normal in IT. IBM System Storage DS5000 works fine most of the time."
"The solution offers an excellent price-performance ratio, including SSDs and compression capabilities. This results in faster performance and potential space savings due to compression."
"The IBM System Storage DS5000 Series can be integrated into various platforms such as IBM, Intel, Linux, and others. It provides flexibility in integration wherever storage is required."
"The most valuable aspects of the DS5000 Series are its high availability (almost six nines), stability, cost-effectiveness, and the unique IBM FlashCore modules, which other competitors lack. These FlashCore modules enable local operations on the drive itself without a performance overhead, a significant advantage."
"The initial setup is pretty straightforward."
"We use it for applications, databases, media, files, etc."
"The solution is reliable."
"The stability and performance of the drive are the most valuable."
 

Cons

"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"It has room for improvement in the area of stability."
"I would like to see an improvement in the handling of large amounts of rights."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"GUI interface should be enhanced more as there is some issues in copy services."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"I would like to see bigger modules."
"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."
"Regarding improvements, there's a common perception, primarily during pre-sales, that IBM storage solutions are expensive, though studies often prove otherwise. As for additional functionality, supporting two to three sites for applications might be a potential enhancement."
"The product should improve its support."
"I find the solution isn't so easy to understand. A user must be quite knowledgeable in the product. It isn't like HPE 3PAR, which you can use quite easily without too much storage experience."
"The solution's integration with other tools could be improved."
"There are some functions that can only be used in prompt mode."
"The solution is not flexible enough."
"The price of the product is an area of concern where improvements are required."
"I don't like the storage now, as it is in the same data center. I want to separate the data center from the backup to another floor of the building or outside the building in a data center of another provider."
 

Pricing and Cost Advice

"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 solution has good pricing, but it is not cheaper."
"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
"Its price is very good."
"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."
"I would rate the pricing of this solution a four out of five."
"I find the pricing of the solution to be very reasonable."
"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."
"It's an expensive solution."
"This product is priced well. The ratio between cost and productivity is very high and we're happy with it."
"Its price is fair. IBM is quite fair in price when you compare it with others. We also use Hitachi internally, and Hitachi is always a little bit more expensive. NetApp is also a bit more expensive. So, IBM has good positioning in terms of price."
"Compared to other vendors, I think it's expensive."
"It is a competitively priced solution. The cost can vary depending on whether it is purchased from the hardware or the software departments."
"We mounted all the virtualization with less than 1,50,000 USD. We are negotiating to get the tool for 800,000,000 Argentine Pesos. The tool is expensive, but it is worth the money."
"The basic functionalities of the product are provided within the normal license, but users can opt for some optional features from IBM's licensing model."
