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

"It is pretty scalable. It will scale to anything."
"Generally, I find I have less trouble with Spectrum Protect than I have had with the other backup products."
"The ability to use S3 Data Store as a repository."
"It has a lot more capabilities and functions than a lot of other products. Even though it is more complex, the reason is because it gives you a lot more features. This is what I prefer, especially for a long retention."
"The product is very stable."
"Setup has always been straightforward."
"It scales from very small to very large. It is easily the most scalable product out there."
"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."
"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

"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."
"It needs BMR (bare machine recovery) solutions for both Windows and Linux systems."
"The product should improve its GUI. It should also support Windows clustering."
"But for the average user, the product is extremely difficult when compared to other products."
"Scalability needs some work in some areas. The number of volumes needs to be increased drastically."
"I would like to see the operations center be a lot more functional. It was nowhere near as functional as the admin center, and I'm doing a lot of command line with it."
"The license model that they have at IBM, which is due to volume, from a certain volume onward is not the right license model."
"I find the solution somewhat difficult to use with virtual environments or VMware."
"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

"Some of the new advanced features are definitely more into cost savings, e.g., dedupe compression, so doing more with less."
"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."
"We worked our licensing into a capacity model, which is nice. Now, everything is much simpler to manage from a licensing perspective.​"
"The pricing model of this solution is another difficult area, it's very sophisticated in the way they charge. It's based on PBU, which is a type of processor, how, many processors, and you need to put everything into an equation. However, they have different ways of charging or licensing. One way is a back-end volume or front-end volume, which is quite complicated."
"At scale, the consumption license (per TB) is very expensive."
"The pricing of the solution is high in comparison to other products on the market. For example, IBM and Symantec have less costly options."
"The licensing fees are between $8,000 and $10,000 per year."
"The platform is neither highly priced nor inexpensive. I rate the pricing a seven 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."
