Manageable and comprehensive and integrates robust backup features for core banking
It's adequate for my core banking, however, I am looking for another solution for all systems. It is not compatible with other operating systems like Windows or Linux, and lacks a consolidated dashboard from Browser Spectrum. This is why I am searching for another solution. The product also lacks any centralized graphical user interface (GUI), such as Jarek Pod, and I am limited to using a console-based text user interface, which my local partner handles completely.

A scalable solution with Veeam and Vertias alliance
I am impressed with the tool's technical alliance with Veeam and Veritas.  The product needs to improve performance while scaling out. It also needs to improve stability.  I have been using the product since seven years.  I would rate the product's stability a nine out of ten. I would rate the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It integrates well with Spectrum Scale."
"The main thing is to keep the data safe and in files, keep it on tape ready for a request from a bank, and it is working perfectly with all our hardware."
"With data deduplication and compression, we are reducing our overall storage footprint for our disk histories. Therefore, we are reducing the actual cost of the disk for our data protection and data backups."
"We can scale. Today, we have an average backup volume of 100TB a day."
"Regarding stability, it's been rock solid."
"Data reduction definitely reduces costs, not only software costs, but from the infrastructure needed."
"The product helps us do data protection and restoration for disaster recovery (DR)."
"Reliability: It has never had a problem with backups or restores. If you store something, it is there."
"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

"It is not compatible with other operating systems like Windows or Linux, and lacks a consolidated dashboard from Browser Spectrum."
"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."
"The main admin console from the UI cannot do anything in the product. It just allows us to maintain, maybe, 30% to 40%. For the rest, we have to use the command line."
"The reporting could be better."
"The solution could be more user-friendly and provide better monitoring. The monitoring should be improved first since it is a higher priority."
"The solution should have better integration with VMware and with IBM Spectrum Protect Plus."
"The software is very complicated. You have to do a lot of configurations to build a server, and you would need to backup and restore."
"They do not have a unified GUI, they only work on CLI and operations center, which is really complicated for the installation and configuration."
"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

"It is very scalable, but the downside is that it costs money."
"Some of the new advanced features are definitely more into cost savings, e.g., dedupe compression, so doing more with less."
"We have been at our size for a few years. We are not really looking to battle the licensing costs, as this is our primary system."
"That's no longer my department, but I have some past experience with licensing. It is not cheap. I would rate it a three out of five in terms of licensing. In terms of additional costs, there is management overhead. It is a complex solution and a lot of work goes into managing clients. It has gotten better over the years, but compared to its competitor, it is still heavy on management overhead."
"The solution is not cheap."
"The license model that they have at IBM, which is due to volume, from a certain volume onward is not the right license model."
"License-wise regarding IBM, it's licensed per terabyte. And that is after compression and deduplication."
"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."
