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

"With Spectrum Protect, you can use any type of disk to back-end the repositories. It gave us flexibility to use whatever storage we wanted at our secondary site."
"It helps our customers protect their data, especially with stuff like ransomware, compliance, and regulatory requirements."
"When I have to do disaster recoveries, I can do it with this tool."
"With the new features that we have added, it has made a difference as far as faster recovery and speed."
"We like IBM Spectrum's versioning capabilities. It lets us specify how many versions of a file we want to keep and for how long. Also, the archive component of the software helps us a lot."
"All other products contain the same features, but when I'm backing up an IBM Power server I feel more comfortable with IBM Spectrum Protect because it's the same vendor."
"They have recently added support tickets specifically engineered around performance. This has been very useful for us when we run into issues where customers are looking to try to squeeze a lot more horsepower out of older system."
"We've found the product to be quite stable and the performance is very good."
"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

"Software-wise, IBM Spectrum Protect didn't handle virtual machines that well. The license cost is mainly the area for improvement in IBM Spectrum Protect."
"IBM Spectrum Protect could be improved by making the installation easier. Once it's implemented, it's okay. IBM started lagging behind when things started moving to storage and cloud-based solutions. Even though they've recently released updates that give cloud-based protection, personally, I still believe they are not up to par with the likes of Rubrik. The entire product is a little bit clumsy because they have co-joined two different products, so it's complex. Even from a sales/explaining to people what it does point of view, it's complex. Whereas, if you take more current products, it's a single box solution. You reel it in, you fire it up, you do a couple of points and clicks, and off you go, whereas the IBM system is seriously complex. There's a lot of training involved and it's a massively difficult product to sell at this point in time."
"We would like to see bare-metal restorers."
"I am looking forward to new features in the next release. One of the main features is the cloud storage integration, which was one of my main required features. I've had more difficult experiences with other platforms than with this one."
"This product comes up against other products available that are marketed better but the other products that it's in competition with are a single product and this is one of IBM products. If it could be marketed as more for competitors I think that's where it comes short."
"Ease of use."
"The stability could be improved."
"It doesn't integrate with storage pools, with a normal pool. I'd like to see that."
"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."
"The product needs to improve performance while scaling out. It also needs to improve stability."
 

Pricing and Cost Advice

"IBM provides an open license policy, which is more like a gentlemen's agreement."
"We worked our licensing into a capacity model, which is nice. Now, everything is much simpler to manage from a licensing perspective."
"We have found that the pricing is high in our country."
"IBM Spectrum Protect can be considered an averagely-priced product."
"The pricing of the solution is high in comparison to other products on the market. For example, IBM and Symantec have less costly options."
"When compared to the cost of other enterprise products, it seems to be in the same range. However, compared to the cost of non-enterprise products, it is really high."
"The platform is neither highly priced nor inexpensive. I rate the pricing a seven out of ten."
"It can be perceived as expensive since it is designed for enterprise use."
"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."
