Class QoS

java.lang.Object

com.solidfire.element.api.QoS

All Implemented Interfaces:

java.io.Serializable

public class QoS
extends java.lang.Object
implements java.io.Serializable

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

Method Detail

getMinIOPS

public Optional<java.lang.Long> getMinIOPS()

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.

setMinIOPS

public void setMinIOPS(Optional<java.lang.Long> minIOPS)

getMaxIOPS

public Optional<java.lang.Long> getMaxIOPS()

Desired maximum 4KB IOPS allowed over an extended period of time.

setMaxIOPS

public void setMaxIOPS(Optional<java.lang.Long> maxIOPS)

getBurstIOPS

public Optional<java.lang.Long> getBurstIOPS()

Maximum "peak" 4KB IOPS allowed for short periods of time. Allows for bursts of I/O activity over the normal max IOPS value.

setBurstIOPS

public void setBurstIOPS(Optional<java.lang.Long> burstIOPS)

getBurstTime

public Optional<java.lang.Long> getBurstTime()

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.

setBurstTime

public void setBurstTime(Optional<java.lang.Long> burstTime)

getCurve

public Optional<Attributes> getCurve()

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.

setCurve
