Question 1
A financial services client is designing a high-availability solution for a critical Oracle database running on a two-node HPE Superdome Flex cluster. The primary business requirement is to ensure zero data loss (RPO=0) and near-instantaneous recovery (RTO<1 minute) in case of a site-level disaster. The two production sites are 50km apart. Which HPE storage technology should be proposed to meet these stringent requirements?
Answer and explanation
Correct answer: C
RPO 0 requires synchronous replication, and two sites 50 km apart are within metropolitan distance. HPE Primera Peer Persistence uses Remote Copy synchronous mode so the same data is on both arrays, and with an HPE Quorum Witness it performs automatic transparent failover (ATF) of host I/O to the surviving array, meeting the near-instant RTO. 3DC Peer Persistence adds asynchronous periodic replication to a third (tertiary) site and is not needed for two sites. StoreOnce Catalyst is a backup target, Nimble asynchronous replication cannot give RPO 0, and StoreVirtual VSA is a legacy software-defined product.
