Azure NetApp
2 minute read
Overview
- File storage SaaS
- Performance and latency sensitive
- Supports Windows & Linux clients
- Multiple performance tiers
- Standard, Premium and Ultra
- Multiple protocols
- NFSv3
- NFSv4.1
- SMB 3.1x
Throughput calculation (service levels)
- Attributable to a capacity pool
- Differentiated by the volume size and storage type
- A bigger volume improves throughput
Service levels
Per 1 TiB of storage
Ultra; 128 MiB/s
Premium; 64 MiB/s
Standard; 16 MiB/s
Throughput calculation for capacity pools | auto QoS
- The throughout for the entire capacity pool is determined automatically based on
- Service level
- Volume quota
Example 1; a 2 TiB volume on a premium service level would have a throughput of 128 MiB/s (2 TiB * 64 MiB/s)
Example 2; a 100 GiB volume on a premium service level would have a throughout of 6.4 MiB/s (0.1 TiB * 64 MiB/s)
Throughout calculation for capacity pools | manual QoS
- Manual QoS allows you to set the throughput in MiB/s per volume within the capacity pool
- The total volume throughput depends on the size of the capacity pool and the service level
- It is capped by (capacity pool size TiB x service level throughput TiB/s)
- You divide the volumes up so combined they do not exceed the throughout of the capacity pool
Example 1; a 10 TiB capacity pool on a premium service level would have a throughput of 1280 MiB/s (10 TiB x 128 MiB/s). You can then divide this pool into different volumes and assigned different throughput values to each volume that amounted to 1280 MiB/s.
Resize a capacity pool or volume
- You can re-size in 1 TiB increments or decrements
- It cannot be smaller than 4 TiB
To change the capacity pool or volume simply locate it in the NetApp blade and click the elipsys icon and choosing resize. Enter a new value and click OK.
Change the service level of a capacity pool
In the Azure portal locate the capacity pool you want to change. From the buttons select ‘Change QoS type’. Change the QoS type from ‘Atuo’ to ‘Manual’. This will now allow you to change the Throughput MiB/s for the volume within that pool.
