What protocol is typically used for communication between VPLEX and host servers?

The correct answer highlights that iSCSI or Fibre Channel is the standard protocol used for communication between VPLEX and host servers. VPLEX is designed to enable the sharing of storage across geographical locations, and it primarily relies on these protocols to facilitate data transfer efficiently and reliably.

iSCSI (Internet Small Computer Systems Interface) is a protocol that allows SCSI commands to be transmitted over IP networks, making it a popular choice for connecting storage devices to servers. It leverages existing network infrastructure and provides flexibility for virtualized environments.

Fibre Channel, on the other hand, is a high-speed network technology primarily used to connect storage area networks (SANs). It offers high performance and low latency, making it ideal for data-intensive applications.

By utilizing both iSCSI and Fibre Channel, VPLEX can support a wide range of enterprise applications and workloads, improving performance and scalability while ensuring robust connectivity between storage and hosts. This is essential for implementing data mobility and protection features that VPLEX provides.
