When you enable data encryption for an application, you can set up remote key server. You can add multiple remote key servers. When you add a remote key server for the first time, the application disables the local key store. You can enable the local key store again after adding a remote key server. However, it is not recommended to enable local key store when the remote key server configuration exists.

If there is only one empty slot, then you cannot add a new remote key server or a new passphrase. You can use a total of 32 slots. The last empty slot is a reserved slot and you can use that only for changing the passphrase.

Application checks for the remote key server accessibility every 15 minutes. If any of the remote key server goes down, the application generates a Warning alarm. If all remote key servers are not accessible, then the application generates a Minor alarm.
