Infrastructure Technical Specialist II at Clicks Group
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
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 most valuable features are performance and reliability; there are many functions, so the whole product is good."
"The Flash core models offer amazing performance."
"The speed of the unit is its best feature. It performs very well."
"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 crucial feature of IBM FlashSystem is compression."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"Most of the features for the reduction in data compression are useful. It is also very easy to use and administer. Its performance is also good."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The solution is reliable."
"I also like all the software features you get from the IBM System Storage DS5000 Series such as the SVC (SAN volume controller). You can put the code on the controllers, and it really gives you the advantage because you'll have HyperSwap."
"The stability is excellent."
"The most valuable feature is compression."
"The security and velocity for fetching data are valuable."
"The solution is stable. I rate its stability a nine out of ten."
"It is a very stable solution."
"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."
 

Cons

"The solution is not easy to use and could improve."
"Cloud file sharing is an area that needs improvement."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"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."
"They don't offer subscription-based payments."
"The security features can be improved such that the encryption does not affect performance in any way."
"I would like to see an improvement in the handling of large amounts of rights."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"There are some functions that can only be used in prompt mode."
"The price of the product is an area of concern where improvements are required."
"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."
"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."
"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."
"The initial setup is hard."
"The product is very costly. Very few can afford it."
 

Pricing and Cost Advice

"The cost of the IBM FlashSystem is lower than the HPE solution."
"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."
"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"This solution is expensive compared to other solutions."
"The price is a little bit high so is rated a six out of ten."
"I find the pricing of the solution to be very reasonable."
"You purchase it as a bundle and the price is comparable."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"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."
"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."
"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."
