Team Lead for Core Infrastructure at Raiffeisen bank Serbia
Efficient replication and helpful for improving data processing and management
The technology behind Hitachi ShadowImage has been around for a long time, and while it works correctly, it does have some issues. We have experienced problems with it, even though Hitachi provides good hardware. Technical support could also be improved, as it sometimes takes a few days to resolve issues.
LeeLee2 - PeerSpot reviewer
Storage Infrastructure Engineer at Gigabit Technologies Pvt Ltd
Reliable replication has transformed disaster recovery and supports realistic dev-test environments
The best feature NetApp SnapMirror offers is block-level incremental replication, which is the foundation of everything. After the initial baseline transfer, only the changed blocks move across the wire, not entire files or volumes. In a busy storage environment, that is the difference between replication that fits in your backup window and replication that hammers your network all day. NetApp SnapMirror has positively impacted our organization by taking us from a theoretical DR capability, meaning we had a secondary site but had never fully tested a failover, to a validated, tested, documented DR process that we run quarterly, which is a fundamental change in our risk posture. Management can now say with confidence that if the primary site goes down, we recover within two hours with zero data loss on critical systems.

Quotes from Members

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

Pros

"The most valuable features are its ability to handle large databases efficiently and the asynchronous replication capability."
"The most valuable feature of Hitachi ShadowImage is high-speed data transfer from one server to another. Other solutions would have problems with transferring 50 TB of data. I also like that Hitachi ShadowImage is easy to use."
"There are a lot of features that are excellent. The data compression during the transfer, for example, is good. The replication is great. The durability of the solution and the speed of the data moving from one site to another is impressive."
"This solution is easy to implement and easy to use."
"With SnapMirror, the solution is the feature itself that is most valuable. It just replicates the data. It's very difficult to speak about, in the sense that it's similar to the features of a wheel. It is round and it's a part of an automobile."
"The tool seamlessly moves data over the network without putting pressure on the network."
"The product has good performance."
"NetApp SnapMirror stands out for its ease of management, efficiency, and scalability, which align well with our operational needs."
"It's a stable solution; it just works."
"They have a very effective dashboard and good reports."
 

Cons

"API and script configuration in Hitachi ShadowImage is sometimes complicated, so this is an area for improvement. Another area for improvement is that the Hitachi ShadowImage interface isn't as user-friendly."
"We have experienced problems with it, even though Hitachi provides good hardware."
"On very large data sets with a lot of changes, the interval between mirrors can be rather long."
"Compression and deduplication could be improved."
"Multiple tasks in the solution are made by the command line and the GUI can be improved to perform complex tasks."
"This process can get out of control sometimes and cause excessive disk utilization."
"The user interface could be simplified."
"The NetApp storage is entry-level storage. I'd like to see compression and deduplication and encryption improved, and I'd like to have real-time replication so I have a zero RPO."
"They could make continued enhancements in integration with diverse platforms for the product."
"Stability needs improvement."
 

Pricing and Cost Advice

"I don't have pricing information for Hitachi ShadowImage because my manager handled it."
"The product price is reasonable."
"The pricing can be improved."
"The cost is low compared to different vendors."
"It's a highly cost-effective solution"
"SnapMirror is extremely expensive. We had a hard time adjusting to our budget. If rated on a scale of one to ten, with ten being the most expensive, I would definitely rate it ten out of ten."
"It's part of the NetApp Firewall, so it's free."
"The solution has monthly and yearly licensing options."
"The pricing could be improved."
