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 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 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 most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."

"Installing FlashSystem is very easy. It takes less than half an hour, and I can handle it all myself."

"The speed and the ease of installation are the most valuable features, and the IBM FlashSystem is the fastest in the industry."

"I rate the technical support from IBM as a ten."

"IBM FlashSystem is a flexible solution with plenty of features."

"The maintenance service and support from IBM is very good."

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."

"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."

"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."

"We have had a good experience with customer service and support."

"The solution is quite robust and complex."

"The solution is reliable."

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

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

Cons

"We faced power supply failure, multiple SAS drives failure, and at the end both controllers were dead."

"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."

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

"There are some issues on a firmware level."

"I have used support and it needs improvement."

"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel; this is magnitudes lower than competing products."

"The interface of this solution could be improved."

"We had issues when attempting to do a flash, we hope to resolve it soon."

More IBM FlashSystem cons

"The solution is not flexible enough."

"The amount of storage could be increased."

"The stability could be improved."

"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."

"IBM System Storage DS5000 is expensive when compared to other vendors."

"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."

"There are some functions that can only be used in prompt mode."

"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."

Pricing and Cost Advice

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

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

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

"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."

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

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

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."

More IBM FlashSystem pricing and cost advice

"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."

"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."

"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."

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