To configure a cache disk for a subscription gateway, you must purchase a subscription cache disk. This topic describes how to purchase a subscription cache disk in the Cloud Storage Gateway (CSG) console.
Prerequisites
Procedure
Note A cache disk depends on a specified gateway. The billing cycles of a cache disk and
a gateway may cause conflicts. For example, assume that you purchase a subscription
gateway at the beginning of a month, and then purchase a subscription cache disk in
the middle of the month. The billing cycles of the gateway and cache disk are both
one month. If you set "Expiration Policy" to "Switch to Pay-as-you-go" when you create
a gateway, you can delete the gateway after it expires at the beginning of the next
month. If you set "Expiration Policy" to "Release", the subscription gateway will
be released upon its expiration at the beginning of the next month. In this case,
the subscription cache disk is released at the same time, and the cache usage fee
is not returned.
