Technological Infrastructure Manager at Mercado Argentino de Valores S.A.

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

"The technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."

"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."

"The initial setup was easy, understandable, and straightforward."

"FlashSystem offers proven technology in a compact package."

"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 most valuable features are performance and reliability; there are many functions, so the whole product is good."

"If you are looking for a great flash solution that can be virtualized or utilized as a building block for a scalable flash solution, or if you're looking for flash for a very specific workload, then you may want to consider a FlashSystem 900."

"The ease-of-use and scalability are the most valuable features."

More IBM FlashSystem pros

"The most valuable feature is compression."

"The solution is stable. I rate its stability a nine out of ten."

"IBM System Storage DS5000 series enhances clients' data handling capabilities through improved security, fast systems, and added value features."

"The stability and performance of the drive are the most valuable."

"IBM System Storage DS5000 series is highly reliable, which is evident by clients' systems still operating effectively after seven or eight years."

"The tool is very stable...The solution's scalability is very good."

"The solution is reliable."

"The solution is quite robust and complex."

Cons

"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."

"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."

"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."

"We sometimes had a problem with some bugs in FlashSystems. One time, one FlashSystem was burnt up. There was some smoke and the data was damaged."

"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."

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

"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."

"It has room for improvement in the area of stability."

More IBM FlashSystem cons

"It would be nice if duplication was possible at the hardware level. As it is now, duplication is a software feature, whereas compression is a hardware feature."

"The product should improve its support."

"Improving software installation and licensing retrieval would make using IBM System Storage DS5000 series easier for customers."

"The product is very costly; very few can afford IBM System Storage DS5000 Series, and the renewal or maintenance of the solution is also expensive."

"The stability could be improved."

"IBM is not always as agile as other competitors when it is about cloud integration and user interfaces."

"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."

"If you decide to expand the IBM System Storage DS5000 Series by adding an extension frame to the controller, you won't have the ability to incorporate flash storage models directly. Instead, you'll need to work with SSD which may be slightly slower."

More IBM System Storage DS5000 Series cons

Pricing and Cost Advice

"The price of IBM FlashSystem is reasonable."

"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."

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

"The total storage capacity vs price is still quite high for the IBM Flash Array."

"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."

"Its price is very good."

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

"The solution has good pricing, but it is not cheaper."

More IBM FlashSystem pricing and cost advice

"It's an expensive solution."

"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."

"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."

"This product is priced well. The ratio between cost and productivity is very high and we're happy with it."

"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."

"It is a competitively priced solution. The cost can vary depending on whether it is purchased from the hardware or the software departments."
