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
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 feature is reliability."
"IBM FlashSystem has been stable in our operations."
"The valuable feature is autoscalling."
"It's a mature product. It's like a BMW that evolves consistently."
"IBM products at the enterprise level are stable solutions, with a score of nine out of ten for stability."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"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 initial customer technical support was efficient and effective."
"The solution is reliable."
"The most valuable feature is compression."
"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."
"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 and performance of the drive are the most valuable."
"It is a very stable solution."
"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."
 

Cons

"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"GUI interface should be enhanced more as there is some issues in copy services."
"The solution's pricing is a bit high so there is room for improvement."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"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 GUI needs some improvement."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
"The initial setup is hard."
"IBM System Storage DS5000 is expensive when compared to other vendors."
"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."
"The price of the product is an area of concern where improvements are required."
"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."
"Improving software installation and licensing retrieval would make using IBM System Storage DS5000 series easier for customers."
"The solution is not flexible enough."
"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."
 

Pricing and Cost Advice

"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."
"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."
"If five is a good price and one is a high price, I would rate the price a two or three out of five."
"Regarding licensing make sure you add at least three years software maintenance from IBM at the beginning, because you will not be able to download firmware updates or any fixes/patches without this."
"This solution is expensive compared to other solutions."
"The tool is cost-efficient."
"The price is a little bit high so is rated a six out of ten."
"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."
"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."
"Compared to other vendors, I think it's expensive."
"It's an expensive solution."
"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."
"It is a competitively priced solution. The cost can vary depending on whether it is purchased from the hardware or the software departments."
