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.

A stable unified storage system that enables quick access to data
The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem.

Quotes from Members

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

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 system would work well for the customer."
"IBM System Storage DS5000 series enhances clients' data handling capabilities through improved security, fast systems, and added value features."
"It is a very stable solution."
"The most valuable feature is compression."
"You can easily virtualize and share the storage."
"The stability is excellent."
"The solution is stable. I rate its stability a nine out of ten."
"I like its storage capacity, quick access to the data, speed, and overall storage management."
 

Cons

"IBM is not always as agile as other competitors when it is about cloud integration and user interfaces. They're not renewing themselves very often. They have been slow to evolve from the old GUI. The user interface should be improved, especially regarding performance analysis, which has always been a little bit weak as compared to other solutions. As a global solution, it lacks the feature for containing integration object storage. Even though they have now started to offer this feature, it is quite young and not as developed as some other vendors. There are also no mass possibilities at all. They have a lot of competition in the mid-range segment. They need to have a NAS gateway or something like that. It doesn't specifically need to be integrated into the controllers that are keys to the gateway."
"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."
"The solution's integration with other tools could be improved."
"The stability could be improved."
"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."
"There are some functions that can only be used in prompt mode."
"The amount of storage could be increased."
"The product should improve its support."
"The main thing Oracle can improve is the cost. It would be better if Oracle opened up the system to enable integration with other vendors. Whether it's the database, application server, or storage appliance, they should make it easy to integrate them. They need to open up more to ensure that it can work in any environment and IT ecosystem."
 

Pricing and Cost Advice

"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."
"This product is priced well. The ratio between cost and productivity is very high and we're happy with it."
"It is a competitively priced solution. The cost can vary depending on whether it is purchased from the hardware or the software departments."
"Compared to other vendors, I think it's expensive."
"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."
"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 price could be better. We have many competing products now like Huawei and Dell EMC, and these are slightly cheaper."
