The Challenge
 Workloads do not get predictable performance
 Limited trust of multi-tenant nodes
 Grey machines (unhealthy state) are not avoided
 Workload scheduling is less than optimal

The Solution
• Intelligent Workload Placement based on ability of nodes
to meet service level objectives
• Compute node capacity and utilization metrics normalized
for use across generation of CPUs
• VM performance monitoring and assurance with cache
contention and ‘Noisy Neighbor’ detection
• Reporting of trust of VMs and nodes – BIOS, Hypervisor
whitelisting and attestation

14. Why Intel® Service Assurance
Administrator?
Match workloads to platforms,
based on capability and
capacity
Find and address software-
defined infrastructure issues
Service assurance for
trust-attestation
• Performance metric
infrastructure capacity
and utilization
• Cache Contention
• System health
• Resource metering
• Boot time trust
attestation of nodes
• Whitelisting
Intel® Architecture Platform Monitoring and Control
“What size virtual machine must
I use for my app?”
“My app is slow sometimes –
How do I diagnose? “
Do I have ‘noisy neighbor’
VMs?”
“Are my VMs running on trusted
platforms?”

15. Automation
Enhance OpenStack* to provision and
monitor machine flavors with specified
service levels
Automated software-defined
infrastructure
Intel® Service Assurance
Administrator Efficiency
Integrate with IT operations tools to
determine probable root cause, report,
and help remediate issues
Efficient service assurance and
administration
Agility
Run workloads with confidence on
software-defined infrastructure
Agile business service deployment
Enhanced Machine Flavors

16. Key Challenges in Cloud
Performance AssuranceHow big a
VM do I
need for
my
workload?
What resources
should be
reserved, how
much burst
capacity?
What metric
do I use to
specify and
measure
performance?
What is the
performance
capacity of the
node?
Intel® Service Assurance Administrator defines Service Compute
Unit as a performance metric for use by cloud administrators
What is the
performance capacity
of the machine
flavor?
Am I getting specified
performance without
interference from
‘noisy neighbors’?

Service Assurance of
SCU units
SCU = function of (frequency, throughput,
instruction set efficiency, cache size)
1 GCEU = 2.5 SCUs (Approximate)
1 EC2 = 2.5 to 3 SCUs (Approximate)
SCUs can be set to define a floor (guaranteed
capacity) and ceiling (burst capacity)

19. How much performance capacity are available on my
host?
19
For each compute node, performance
capacity status for OS and VMs are
monitored continuously, displaying how
much resource is available, e.g. SCU and
number of cores available

20. How much cache contention are there in the compute
nodes?
20
Using Cache Monitoring Technology,
console displays LLC Cache Contention
status for the OS and VM on each compute
node

21. Extending flavors with VM bursting and assurance
capabilities
21
VM will only be created on
nodes that have been trust-
attested to be safe during
boot
VM will reserve 1 SCU of compute
performance, and burst up to 2 SCU
based on available compute
resources

22. Extending flavors with trust and core-pinning capabilities
VM will reserve one
dedicated core from the
CPU compute resource
VM will only be created on
nodes that have been trust-
attested to be safe during
boot

23. Finding out the performance consumption level for each
compute node at the OS level
Allocating SCU for OS
level consumption of
compute resource

24. Finding out VM core-pinning status and metrics
Core Pinning, VM received
dedicated core from the
CPU
VM SLO status include
number of cores assigned
and VM uptime

25. Learning more about each VM SCU utilization metrics
Real Time VM SCU
utilization and core
pinning metrics

26. Conducting probable cause analysis of “Noisy Neighbors”
problems
Cloud Administrator can take remedial action (e.g. evacuate a VM to a different node)
once Intel® SAA has identified Noisy Neighbors (VMs aggressively using shared
compute resources in the platform, like CPU cache) and VMs that are affected.

27. Intel® Service Assurance Administrator Key Feature
