OmarIsmail1 - PeerSpot reviewer
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

"This solution is very stable."
"The most valuable features are performance and reliability; there are many functions, so the whole product is good."
"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."
"IBM FlashSystem is the best solution for storage virtualization."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The most valuable feature is reliability."
"The power systems are very reliable if you are running 24/7 operations. For ongoing mission-critical applications, it's the best solution."
"The most valuable feature of the solution is compression."
"The security and velocity for fetching data are valuable."
"The system would work well for the customer."
"The stability and performance of the drive are the most valuable."
"The most valuable feature is compression."
"The initial setup is pretty straightforward."
"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."
"IBM System Storage DS5000 series enhances clients' data handling capabilities through improved security, fast systems, and added value features."
"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."
 

Cons

"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."
"The solution has a low number of NVME host attachments at 16 per IO group over the fiber channel."
"The initial setup is complex."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"The solution is quite expensive. That's one of the downsides to using it."
"I think the only thing the developers can look at, is that it is limited to 25 gigabytes currently. In the next release they might want to increase that."
"It could be easier to implement."
"The pricing is high; storage solutions are always expensive. I do not know if the price needs to be reviewed, but it is worth considering."
"The solution's integration with other tools could be improved."
"The product is very costly. Very few can afford it."
"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."
"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."
"Improving software installation and licensing retrieval would make using IBM System Storage DS5000 series easier for customers."
"The product should improve its support."
"There are some functions that can only be used in prompt mode."
"The solution is not flexible enough."
 

Pricing and Cost Advice

"I would rate the pricing of this solution a four out of five."
"Overall the price of the solution is expensive and this includes the license."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."
"The pricing has been very competitive for the last few years. IBM got to the point where they changed the pricing model and we feel very comfortable with the pricing. It's very competitive. Over the last two years, IBM has been coming up with all kinds of interesting promos, especially for the SMB systems. That makes it very competitive price-wise and in terms of performance..."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"They've been much more aggressive in the last five, six years than they were before that."
"The total storage capacity vs price is still quite high for the IBM Flash Array."
"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."
"It's an expensive solution."
"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."
"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."
"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."
