QoS Class

QoS Quality of Service (QoS) values are used on SolidFire volumes to provision performance expectations. Minimum, maximum and burst QoS values can be set within the ranges specified in the QoS table below. Volumes created without specified QoS values are created with the Default values listed below. Default values can be found by running the GetDefaultQoS method. minIOPS Min: 100/50 (v7.0/v8.0), Default: 100, Max: 15,000 maxIOPS Min: 100/50 (v7.0/v8.0), Default: 15,000, Max: 100,000 burstIOPS Min: 100/50 (v7.0/v8.0), Default: 15,000, Max: 100,000

public class QoS : RpcBase

The QoS type exposes the following members.

Constructors
  NameDescription
Public methodQoS
Initializes a new instance of the QoS class

Properties
  NameDescription
Public propertyBurstIOPS
Maximum "peak" 4KB IOPS allowed for short periods of time. Allows for bursts of I/O activity over the normal max IOPS value.
Public propertyBurstTime
The length of time burst IOPS is allowed. The value returned is represented in time units of seconds. Note: this value is calculated by the system based on IOPS set for QoS.
Public propertyCurve
The curve is a set of key-value pairs. The keys are I/O sizes in bytes. The values represent the cost of performing an IOP at a specific I/O size. The curve is calculated relative to a 4096 byte operation set at 100 IOPS.
Public propertyMaxIOPS
Desired maximum 4KB IOPS allowed over an extended period of time.
Public propertyMinIOPS
Desired minimum 4KB IOPS to guarantee. The allowed IOPS will only drop below this level if all volumes have been capped at their minimum IOPS value and there is still insufficient performance capacity.
