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

"Our customers have come to trust IBM."
"The technical support for Spectrum Protect is very mature. It is very committed to giving a top-notch support experience."
"It has to ability to backup DV2, Oracle, and Informix."
"Overall, my experience with the solution is very positive, and I rate it a 9 out of 10."
"We cannot live without it, since it gives us the confidence to move forward."
"The diversity and flexibility of the application, no matter what the problem is, I can solve the problem any number of ways based on the customers’ requirements."
"Two weeks ago, we were able to restore services as quickly as possible in a production environment, kickstart and provide services on that particular server to customers, which saved us a lot of embarrassment."
"Overall, it is a well-rounded solution."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"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."
 

Cons

"For the database side, it does not have object level recovery."
"At one point, we tried to implement the VMware module with it, and it was awful and terrible."
"The initial setup is complex."
"Easier configuration of some of the products, e.g., VE comes to mind."
"The version that we had when I first started made it look really bad. We are talking about commands that should have run in two seconds, but instead took four to eight hours. Other components were sluggish."
"Some features are outdated as the product does not use the latest technologies. The graphical user interface, known as the operation center, is not very well designed. Additionally, IBM Storage Protect does not work well with virtual environments such as VMware and Hyper-V."
"There have been scalability issues. The core product does not support scale out. We needed to create a new system and manage resources separate from the existing one."
"Scalability is poor. As you get to bigger environments, this is where our gaps have been introduced."
"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

"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."
"IBM Spectrum Protect, cost-wise, has way higher pricing than Veeam. By switching over to Veeam, my company saved over $600,000 in USD. The IBM Spectrum Protect pricing is a two on a scale of one to ten. My company paid additional fees for maintenance, apart from the standard licensing fees."
"It is very scalable, but the downside is that it costs money."
"The price of IBM Spectrum Protect is expensive and there is only a standard licensing fee."
"Its licensing is complicated. It goes by CPUs, and it is pretty expensive as well."
"The licensing is varied. If we have small environments (not many TB being managed) it is best to license by PVUs (depending on the number of cores of the machine). If we manage many TBs we look at licensing by capacity which allows us to use all the agents of the product."
"It is expensive."
"It's very complicated. Licensing is a pain."
"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."
