Which problem is addressed?

Storage performance (IOPS, throughput) is limited in an array

Several workloads compete for the same resources

Manual tuning is complex

3 © 2016 Fujitsu Technology Solutions

Traditional Approach – Manual Tuning

Split disk resources into several pools

Set speed limits (Quality of Service)

But...

This requires constant monitoring

Resources are wasted

No guaranteed response

time

Hard to maintain

Traditional QoS does not consider

response times

Fujitsu‘s Automated QoS Approach

1 ETERNUS Automated QoS

1 2

Define priority or response time

1. Measure performance

2. Compare defined priority with measured performance

3. Modify system parameters to attain defined priority

Operation Mode: Automated QoS Priority

In this mode, the target

response time for each volume

is set automatically, based on

the priority

Target response times are

adjusted automatically

7 © 2016 Fujitsu Technology Solutions

Operation Mode: Target Response Time

In this mode, a target

response is set manually

Volumes can be slowed down

to achieve target response

time and avoid over-

achievement

8 © 2016 Fujitsu Technology Solutions

Cooperation With AST (Optional)

If a response time is not

achievable for a volume,

more blocks can be

promoted to faster disks

How To Set Priorities

Priorities are set on a per-volume basis for each Flexible Tier

Volume (FTV)

Disabled AQoS always means unlimited performance

Current AQoS Tuning Status

The current tuning status is displayed on a per-volume basis in the
