Interim Head of Infrastructure at a real estate/law firm with 1,001-5,000 employees
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.

Expert Backup at a tech services company with 201-500 employees
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

"One way they have improved our organization is through the stability of the solution and the availability of the product."
"I find the whole product useful. The backup archive client, snapshot, spectrum for virtual environments are beneficial features."
"The solution is very stable. It is one of the most important features that we look for in a product before putting it into the market and when establishing a strategy with our customers."
"This solution has improved our organization through better file and database recovery."
"In general, this is a good product; specifically, I like the deduplication and compression features."
"The ability to use S3 Data Store as a repository."
"The stability of the solution is perfect."
"Instead of taking three different backups of your systems, you're taking only one, and you're able to crack that open and get what you need."
"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

"The GUI has long been a problem for TSM/Spectrum Protect."
"We have been waiting for solutions for approximately one year."
"Sometimes we experience trouble with the backup transfer of the control files."
"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."
"The technical support really needs to be improved."
"We are still using TSM Manager for many of our projects to administer our platform because the gap was not resolved with the new Operations Center."
"It might be seen as leaning towards the legacy side, missing some features of newer solutions. The main drawbacks would be its complexity and high pricing."
"We would like to see cloud integration."
"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

"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."
"Licensing can be either complicated or simple depending on what type of licensing you wish to use and what works best for your environment."
"It is very scalable, but the downside is that it costs money."
"The solution is not cheap."
"Customers need to pay for licensing in order to use IBM Spectrum Protect. The customers that have been using it for a long time are okay and happy with it. From a cost point of view, it's better for them to renew their licenses than to go through the difficult process of changing a backup product in their environment, and migrate from one product to another."
"The solution has a capacity based licensing, front and back-end license."
"I don't have an idea about the pricing. They send that over to someone else, but I know that one of the issues they had was the licensing costs. I don't think they were happy with how they were charged."
"The solution's pricing is fair. Price-wise, I rate the solution an eight out of ten."
"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."
