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

"For space saving features, it definitely saves us in a virtual environment in terms of space and money."

"Data deduplication is one of the most valuable features of this solution."

"The hardware is the best feature of the product."

"The documentation is excellent so far, the solution is very fast and offers very good flexibility with a pretty decent price point, and the product is user-friendly with an easy setup process."

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

"IBM FlashSystem has improved the way the organizations of my customers function."

"IBM Storwize makes management of the IT environment much easier, with high availability and enhanced security, proven dependability, data compression with hardware acceleration, and advanced copy services features all in this product."

"It is simple to make an update."

More IBM FlashSystem pros

"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."

"You can easily virtualize and share the storage."

"The DS 5000 series never has any problems; it's extremely reliable."

"We use it for applications, databases, media, files, etc."

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

"The solution is quite robust and complex."

"The initial setup is pretty straightforward."

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

More IBM System Storage DS5000 Series pros

Cons

"ISCSI/ISER Bandwidth is at 25gbps. Would be nice if that can keep track with the bandwidth currently available in new dc networking deployments."

"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."

"The initial setup is complex."

"The security features can be improved such that the encryption does not affect performance in any way."

"They don't offer subscription-based payments. You pay for the license."

"The solution should improve its pricing and the mechanism in the reduction pool."

"The several major crashes resulted in the entire weekends being lost in rebuilding the array and then for restoring the data."

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

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 stability could be improved."

"IBM talks about integration when we talk about Safeguarded Copy. It integrates with QRadar, but it seems as though IBM still is too separate, that is, the way IBM is measured on software and hardware."

"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."

"The price of the product is an area of concern where improvements are required."

"The solution's integration with other tools could be improved."

"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."

"The initial setup is hard."

More IBM System Storage DS5000 Series cons

Pricing and Cost Advice

"Overall the price of the solution is expensive and this includes the license."

"Its price is very good."

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

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

"Our customers would like IMB FlashSystem to be less expensive."

"They've been much more aggressive in the last five, six years than they were before that."

"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 tool is cost-efficient."

More IBM FlashSystem pricing and cost advice

"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."

"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's an expensive solution."

"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."

"Compared to other vendors, I think it's expensive."
