Storage pools
Storage pools act as a container for volumes. All volumes in a storage pool share the same region, service level, VPC network, [Active Directory (AD) policy], and [customer-managed encryption key (CMEK) policy]. The capacity to the pool can be assigned to volumes within the pool. Billing is based on region, service level, and capacity allocated to a pool independent of consumption at the volume level.
Supported regions
Service levels
The service level is a property of the storage pool. Service levels have capacity-dependent throughput limits. NetApp Volumes offers two service levels: Premium and Extreme. For a volume to have a different service level, you need to reassign it to a storage pool with the target service level.
| Service level | Throughput per TiB of allocated volume capacity | Workload types |
|---|---|---|
| Premium | 64 MiB/s | Databases and applications |
| Extreme | 128 MiB/s | High-performance applications |
Network
A pool defines which Virtual Private Cloud (VPC) its volumes connect to. The volumes are accessible only for clients that are on the same VPC or those connected to it with a VPN.
Active Directory settings
Some NAS protocols or protocol variations require access to an external directory service. [NetApp Volumes support Active Directory] as the only directory service. You can attach one Active Directory policy to a single pool.
Customer-managed encryption key settings
NetApp Volumes encrypts the data of all volumes at rest using a Google-managed key. you can choose to encrypt the volumes using a customer-managed encryption key (CMEK). You can attach a CMEK policy during storage pool creation and all volumes created in that pool will use it. You can have a mix of storage pools with and without CMEK policies in a region.
Capacity
NetApp Volumes allows you to add or remove capacity to your volume as needed to adjust for any application changes. Capacity is allocated to storage pools and volumes, and can be modified.
Storage pools: You can allocate 2 TiB - 10 PiB of capacity to a storage pool and increase or decrease capacity in 1 TiB increments.
Volumes: You can allocate 100-102,400 GiB of capacity to a volume and increase or decrease in 1 GiB increments.
Volumes
You can assign volumes to storage pools, and also move a volume created within a pool to a different pool with the same settings (region, network, AD policy, and CMEK policy) as long as the target pool has enough spare capacity.
