Backup coverage has supported immutable protection and now needs a more modern, intuitive interface
IBM Storage Protect is from a previous generation of backup software. In those days, backup software was complex in setting up and complex to manage. The new software, such as Rubrik, is very easy to use and more relatable to younger engineers because its interface design is more similar to Office 365 and the newer controls and labels that we are accustomed to. The difficulty that we now have with IBM Storage Protect is that for this day and age, compared to other products that are out there, it seems complex. If we look back 15 years ago, all enterprise class backup software was complex, so IBM was not any different. However, many of these older systems, such as Commvault, still have the same complaint that they are very complex because they have tried to keep that same interface and the same way it works. This suits them, but it probably needed a complete overhaul to bring it into the ease of use that we have with modern software. However, that upgrade has not been done. IBM Storage Protect has not been upgraded into a modern platform. It still looks a legacy platform.

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Good deduplication and compression features."
"If you have mission critical functions, IBM is one of the companies that you trust."
"Performance and recoveries are better. Our clients and customers are happier with the performance of it."
"It is a very reliable, consistent, unhackable product."
"The most valuable features of the product are data deduplication and disaster recovery."
"Because of the flexible parameters, everything can be fine-tuned to the customers’ needs in their environment."
"The deduplication and compression features are the most valuable features."
"The feature we have found most valuable is when you want to integrate it with a Tape Library and then do the DRM life cycle. That is when it works the best."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
 

Cons

"Their support is lacking. I've talked to their developers and stuff in the last couple of weeks and they reassure me that some people have retired, and they're working on getting that bumped back up. But the support lacks a lot to be desired at this point."
"The software is complex; setup is complex."
"Technical support will always be a challenge."
"IBM Spectrum Protect does have a lot of the features that we need, but I think they need to improve their backup virtualization and backup for container."
"The entire product is a little bit clumsy because they have co-joined two different products, so it's complex."
"Scalability is poor. As you get to bigger environments, this is where our gaps have been introduced. As we have grown over the past couple of years, the gaps have become more apparent."
"The usability of IBM Spectrum Protect could be improved, specifically additional features to the product in the operations center. Additional reporting facilities and stronger reporting tools such as build dashboards would be beneficial."
"The pricing is a bit high. It would be ideal if it was more affordable."
"The product needs to improve performance while scaling out. It also needs to improve stability."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
 

Pricing and Cost Advice

"That's a hard estimate. It depends on the licensing, the hardware, and other stuff, but it is fairly expensive. It is generally more expensive than other solutions."
"The license model that they have at IBM, which is due to volume, from a certain volume onward is not the right license model."
"We have spec'd out our build, and the cost of it can work quite easily today for our future needs."
"License-wise regarding IBM, it's licensed per terabyte. And that is after compression and deduplication."
"That's no longer my department, but I have some past experience with licensing. It is not cheap. I would rate it a three out of five in terms of licensing. In terms of additional costs, there is management overhead. It is a complex solution and a lot of work goes into managing clients. It has gotten better over the years, but compared to its competitor, it is still heavy on management overhead."
"One can go with either a PVU licensing model or a capacity based licensing model. Either solution does not block the usage, if over used."
"Use capacity licensing. It's easier and cheaper."
"The product is low cost. It is very cool when we design it to using licensing based on post capacity."
"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
