What is SRDF Replication? – nixdrafts

Webn traditional vSAN clusters, a virtual machine’s read operations are distributed across all replica copies of the data in the cluster. In the case of a policy setting of NumberOfFailuresToTolerate =1, which results in two copies of the data, 50% of the reads will come from replica1 and 50% will come from replica2. WebSRDF Synchronous (SRDF/S) – SRDF/S delivers zero data loss remote mirroring between data centers separated by up to 120 miles (200 km). SRDF Asynchronous (SRDF/A) – SRDF/A delivers asynchronous remote data replication between data centers up to 8000 miles (12,875 km) apart. gb this pc

WebFeb 15, 2024 · For highly mission-critical applications, synchronous replication is always preferred, even at the sacrifice of distance. One compromise is to implement synchronous data replication to a regional facility, followed by asynchronous replication between the regional facility and some more distant DR site. Page 2: Complimentary New … WebIn a scenario where a major service outage occurs for one replicated data center (that is, one replication site), a service failover to the operational mate replication site can be performed. A typical customer deployment model for replicated data center infrastructure is to have a pair of replication sites located some distance apart (perhaps 50 or 100 miles).
