An administrator wants to select a SAN with high availability features. Which of the following would be MOST applicable to high availability?

Hot swappable components, such as power supplies, fans, or disk drives, are crucial for high availability because they can be replaced while the SAN system remains online and operational. This capability significantly reduces downtime by allowing maintenance or repair without interrupting service, thus ensuring continuous data access.

Solid state drive (SSD) support improves performance and energy efficiency but does not inherently provide fault tolerance or continuous operation during component failure.

Snapshot support provides point-in-time copies of data for backup and recovery, contributing to data protection, but not directly to continuous system availability during component failure.

Email alerting is a notification mechanism that informs administrators of issues, which is important for management but does not directly ensure continuous operation or prevent downtime.
