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

"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."

"No queuing and high ops, speed, and performance."

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

"The most valuable features are flexibility and performance."

"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."

"The IBM System is top-notch and offers all the features we need to keep going for another 5 years."

"Stability-wise, this solution is fine."

"I think the v7000 is versatile, reliable, and gives really good performance in the configuration you choose."

More IBM FlashSystem pros

"You can easily virtualize and share the storage."

"We use it for applications, databases, media, files, etc."

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

"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 solution is stable. I rate its stability a nine out of ten."

"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."

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

"It is very strong in block storage for the database environment."

Cons

"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."

"The security features can be improved such that the encryption does not affect performance in any way."

"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."

"The product needs to improve their scalability."

"The solution is not able to replicate data in one-to-many scenario."

"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."

"In the next release having the next level of high-speed performance would be great."

"The initial setup is complex."

More IBM FlashSystem cons

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

"The solution is not flexible enough."

"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."

"I find the solution isn't so easy to understand. A user must be quite knowledgeable in the product. It isn't like HPE 3PAR, which you can use quite easily without too much storage experience."

"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."

"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."

"I find the solution isn't so easy to understand. A user must be quite knowledgeable in the product."

Pricing and Cost Advice

"I price of IBM FlashSystem is reasonable and competitive."

"You purchase it as a bundle and the price is comparable."

"Its price is very good."

"For a yearly license, it is about $100,000. There are no additional costs. The entire system is included."

"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."

"The pricing is competitive in our country."

"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."

"The pricing is reasonable."

More IBM FlashSystem pricing and cost advice

"It's an expensive solution."

"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."

"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 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."

"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."

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.
