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 really user friendly. It also offers good performance and is highly reliable."

"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."

"This product is so easy to use."

"The most valuable feature of the solution is compression."

"The most valuable features of all the products are the high performance and micro latency."

"The most valuable features were the performance of the array, i.e., very low latency and high IOPS, plus the management interface is very easy to use."

"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."

"IBM FlashSystem is the best solution for storage virtualization."

More IBM FlashSystem pros

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

"You can easily virtualize and share the storage."

"IBM System Storage DS5000 series enhances clients' data handling capabilities through improved security, fast systems, and added value features."

"The system would work well for the customer."

"The tool is very stable...The solution's scalability is very good."

"The solution is reliable."

"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."

"The stability is excellent."

Cons

"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."

"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."

"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."

"There is a need for a little bit more of a drill down in the GUI part."

"The GUI needs some improvement. An additional function that could be helpful is reducing the time it takes to delete volumes, especially if they are compressed or deduplicated."

"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."

"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."

"The solution's infrastructure technology level could be PCI Express 5 instead of PCI Express 4 for the next version."

More IBM FlashSystem cons

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

"The solution's integration with other tools could be improved."

"The solution is not flexible enough."

"Improving software installation and licensing retrieval would make using IBM System Storage DS5000 series easier for customers."

"The product is very costly. Very few can afford it."

"The initial setup is hard."

"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."

Pricing and Cost Advice

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

"Pricing can be considered as per market competition."

"The price is a little bit high so is rated a six out of ten."

"The price of IBM FlashSystem is reasonable."

"I'd rate the basic licensing and the Virtualize software a ten out of ten, and the extra Spectrum and other an eight out of ten."

"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."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"IBM V7000 has a new license and price structure which provides intuitive licensing based on the functions customers wish to enable and use the most."

More IBM FlashSystem 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."

"Compared to other vendors, I think it's expensive."

"It's an expensive solution."

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

"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."

"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."

Overview

IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.

IBM

DS5000 storage systems are equally adept at supporting transactional applications such as databases and online transaction processing (OLTP), throughput-intensive applications such as high-performance computing (HPC) and rich media, and concurrent workloads for consolidation and virtualization. DS5000 series storage systems can support service level agreements (SLAs) for the most common operating systems, including Microsoft Windows, UNIX, Linux and Apple Macintosh.
With drive-level encryption, DS5000 series storage systems support affordable data security with no performance penalty. The DS5000 storage system’s multiple replication options, drive-level encryption, and persistent cache backup can help ensure that any data in cache is captured and safe in the event of a power outage.
