QuestionQ21

Describe the HPE Storage portfolio as it relates to enterprise infrastructure.

An existing HPE 3PAR 8200 Peer Persistence configuration for a VMware vSphere stretched-cluster configuration is due for renewal within the next 6 to 12 months.

What performance improvement over the old setup would result if an HPE Alletra Storage MP Bl0140 configuration replaced the existing configuration?

  • A Ability to access both ends of replicated volumes pair concurrently.
  • B Support for lower latency RCIP transport.
  • C Port persistence over both arrays for seamless failover.
  • D More host ports to load balance the storage i/o.
Explanation

HPE Alletra Storage MP Active Peer Persistence supports active-active host access: the replicated LUNs have the same WWN and can service read/write I/O through both the primary and secondary storage systems. In contrast, legacy 3PAR Peer Persistence uses active paths to the primary system and standby paths to the secondary system for a given volume. Concurrent access to both ends of the replicated volume pair can reduce remote I/O and improve performance in a stretched-cluster deployment.
