Senior System Engineer at a manufacturing company with 10,001+ employees
Offers reliable recovery and backup but needs better ransomware protection
With ransomware protection and cyber protection, more improvement is possible. IBM provides these through a third party, so enhancement is needed. There's significant room for improvement. They are not yet where I want them to be. It does not offer horizontal and vertical scaling. These are areas IBM can improve.

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

"The solution is scalable."
"The API is very good."
"The initial setup of IBM Protect Plus is simple and not complex."
"The most valuable features of the solution stem from the fact that the product works and helps with restoration areas whenever there is a need to restore something."
"The most valuable feature is the ease of use."
"The most valuable feature of this solution is the integration with Oracle."
"The tool has enough documentation; you don't need to contact the support team."
"Virtual snapshots that offer incremental backups."
"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 tool needs to increase the number of threats."
"The administration needs to be improved and made simpler to use."
"The solution only supports HyperV and VMware but doesn't support Nutanix."
"The replication feature is not available."
"IBM Spectrum Protect Plus could be made more lightweight and user-friendly in terms of GUI features to make it closer to a perfect score."
"An area that needs improvement is data validation. We currently use another product that gives us immediate validation, information about when the last backup was, and no risk of corruption happening. TSM in IBM Spectrum is not mature so that you can validate on the spot."
"It requires much more automation features."
"The Gui interface and usability are not so friendly and easy."
"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

"We have a perpetual license for the tool since it is deployed on-premise."
"The licensing model of Spectrum Protect Plus is more efficient and cheaper compared to the original."
"In addition to the standard licensing fees, we paid for implementation and training."
"I rate the price of IBM Spectrum Protect Plus a one on a scale of one to ten, where one is extremely expensive, and ten is very cheap."
"The price offering from IBM is coming down because it is based on number of VM machines. So, IBM is coming to the market to show the added value of the product."
"Depends on the licensing options that you choose."
"Clients prefer to buy a perpetual license, but the majority opt for a yearly subscription."
"IBM Spectrum Protect Plus is a little expensive."
"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."
