Remote storage space

The Remote Total Primary Storage pie chart in the link status Overview panel for an active/active link or an outbound active/passive link during replication shows the amounts of free and used space in primary storage for the other system involved in the link. Each amount is also shown as a number of bytes.

In a SAIN system with spindown storage, the storage being measured in this chart includes both primary running storage and primary spindown storage. In this case, a second pie chart to the right, labeled Remote Primary Running Storage, shows the amounts of free and used space in only primary running storage.

The two systems involved in a replication link do not necessarily have the same storage capacity or storage tiering strategies. If a system receiving replicated data starts to run low on free space in primary running storage, you need to evaluate whether to take action on that system to address the issue (for example, by increasing the primary running storage capacity or by tiering more data to other types of storage).

When primary running storage in the remote system for a replication link is almost full, the Overview page in the HCP System Management Console for the local system displays an alert. When the storage is full, the Console displays a different alert, and HCP automatically suspends replication on the link. For more information about these alerts, see System Management Console alerts.

For information about different types of storage, see Storage for HCP systems.
