Offers cost-effective storage for small companies with budget constraints

IBM FlashSystem 5300 is offered at a very low cost in Israel, which is advantageous for small companies. However, other features like deduplication and compression do not perform effectively. The price sensitivity makes it a viable option for clients with budgetary constraints, as it allows us to secure deals based on the cost rather than advanced performance.

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

"Flash disk with Easy Tier option"

"The compression and deduplication features are the most valuable."

"The most valuable features are deduplication and compression."

"I rate the technical support from IBM as a ten."

"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."

"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 products at the enterprise level are stable solutions, with a score of nine out of ten for stability."

"The all-flash storage has tier replication capabilities."

More IBM FlashSystem pros

"The system would work well for the customer."

"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 security and velocity for fetching data are valuable."

"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."

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

"You can easily virtualize and share the storage."

"It is a very stable solution."

"The stability is excellent."

Cons

"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."

"Events/log analysis tools."

"The product could be cheaper."

"They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something."

"The storage capacity of this solution could be improved."

"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."

"The interface of this solution could be improved."

"Product support is restricted to IBM only. It must be decentralized to IBM partners as well."

More IBM FlashSystem cons

"IBM System Storage DS5000 is expensive when compared to other vendors."

"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."

"The stability could be improved."

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

"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."

"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."

"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."

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

More IBM System Storage DS5000 Series cons

Pricing and Cost Advice

"This solution is expensive compared to other solutions."

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

"If five is a good price and one is a high price, I would rate the price a two or three out of five."

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

"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..."

"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."

"The price of IBM FlashSystem is reasonable."

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

More IBM FlashSystem pricing and cost advice

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

"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."

"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's an expensive solution."

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.
