Azure storage capacity reservations are available in units of 100 TB and 1 PB per month. The reserved capacity can be for a single subscription or can be shared across multiple subscriptions for a customer.

Azure storage capacity reservation discounts are only applicable to the data storage charges. There will still be pay-as-you-go costs associated with other associated activities such as bandwidth and data transfer while accessing the stored data.

Reservations can be purchased through the Azure portal.
