SolidFire QoS
SolidFire Element QoS is the most advanced QoS control available
for provisioning performance in a multi-tenant cloud environment.
All volumes on a SolidFire cluster can be easily provisioned to
ensure a specific level of performance to control the IOPS and
allocated bandwidth. This allows for performance SLAs to be
configured into each new cloud storage offering on the
cluster.
Each volume on a SolidFire storage cluster is configurable
for:
Minimum IOPS:
Configuring the minimum IOPS guarantees a level of performance and represents an overall system priority. Volumes with a lower minimum IOPS will get lower performance priority when a system is overloaded.
Maximum IOPS:
Configuring the maximum IOPS puts a cap on the sustained IOPS that will be allowed on a volume regardless of how much performance is available on the system.
Burst IOPS:
Burst IOPS allow for short term performance spikes to go over the maximum if the volume has been running below maximum before the burst occurs.
Maximum and Burst MB/s:
Maximum and Burst MB/s work similarly to the IOPS maximum and burst but typically only apply to workloads that are using large block sizes as the IOPS limit is reached first on most applications.
Changes to QoS settings can be made at any time to dial performance into any desired level. The performance affect is immediate and requires no data movement within the system. All settings are controllable via API allowing SolidFire QoS to be integrated into any management or automation stack.
