Cons

"Integration with cybersecurity measures can be enhanced, particularly with ransomware protection."
"The Data Domain solution appliance is quite expensive."
"The price is also a disadvantage. Price is a disadvantage with the PowerProtect as it needs to be cheaper."
"The tool's pricing could be cheaper."
"The size and scale of the product are limited and could be improved."
"The Data Domain solution appliance is quite expensive. It is on the higher side, but technically or functionally, there is no issue."
"EMC is very expensive for small customers."
"The usage of this solution is a bit difficult to develop processes, and it takes a long time to market permits."
"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

"The yearly subscription is very affordable for our customers, but the price could be a little cheaper overall."
"The price of the solution and support for Dell PowerProtect DD is expensive. We have customers that cannot upgrade to a newer version of the solution because the support is too expensive."
"The pricing is cost-effective for the solution"
"If we do not move to the cloud solution and stay with our on-premise version we will miss some new features."
"The price of Dell EMC PowerProtect DD could improve, it is expensive."
"The price is on the high side."
"We usually buy products at the end year, and the license is included."
"Pricing is related to size. A lower range solution might be about $33,000. My customers use higher range versions with a price of around $100,000. That's the price for both the hardware and software."
"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."
