Dell SRDF (Symmetrix Remote Data Facility ) [EOL] vs Vision Solutions Double-Take comparison

"Customer Service: Very good. Technical Support: Very good."

"We've found the support to be very good overall."

"The SRDF solution has improved our disaster recovery RPO to near zero or less than 15 minutes with RTO getting drastically reduced."

"Customer Service: Top notch. Technical Support: Excellent."

"The feature of taking snapshots from the replicated volumes has allowed us to use them for DR testing to validate the application consistent point of recovery."

"In all the companies in which I have used the product the ease of Disaster Recovery was implemented in such a manner that the risk of a site disaster was mitigated in an efficient way, and it made the migrations of complete data centers to other new data centers at other locations a piece of cake."

"Customer service for this product was top notch."

"We've found the support to be very good overall."

"It gives us the possibility to migrate/protect customer servers and data in the simplest way."

"It takes less time to replicate files between two servers."

"Customer Service: Second to none Technical Support: Second to none"

"In Version 7.xx the most valuable feature to me is being able to carry out a test full server failover in which case the primary server is still up and running."

"If you are new to the product, the initial setup might be a bit difficult."

"The main pain point that we experienced is during device creation."

"In general, it’s very stable although some time SRDF don’t behave as expected specially if the link is not stable or saturated."

"The main pain point that we experienced is during device creation. For every newly provisioned volume, creating replication relationships between production and DR site, creating snapshots for third copy at DR site, and configuring them in appropriate replication groups and device groups means that there are lot of steps involved and a lot of room for error. There has to be a lot of checks and balances which need to be incorporated to make sure that the solution is set up correctly."

"If you are new to the product, the initial setup might be a bit difficult."

"As of late I have seen the replication drop but this was not due to the SRDF, it was due to the high rate of IO changes on the OS side."

"Our ROI was minimal, because we use it for a cold, disaster recovery method."

"SRDF compared with EMC Recover Point has less capabilities, for ex. CDP (local or remote) is missing, only EMC assets compatibility, as a TCO is more expensive than implementing IBM SVC or EMC VPLEX virtualization and replication (more supported assets)."

"Not such a good coverage of the most widely used Linux server distributions, so many issues happen while migrating these servers."

"Yes I encountered issues with deployment. The information provided in the guide just stated about 2 or 3 communication ports but even after these ports are enabled there are still issues with the 2 servers communicating via Double-Take."
