How does a SAN fit into a hybrid IT or colocation strategy?

Modern SANs work well in colocation environments because they benefit from the dense, well-connected, environmentally controlled space that a quality data center provides. Many enterprises now run their SAN in colocation while extending replication or backup tiers to the cloud, getting the performance of on-prem block storage with the resilience of off-site copies. This pattern is especially common for organizations that need compliance-grade data control but want to avoid the cost of building and operating their own facility.
