Guaranteeing Performance in High- Density OpenStack Environments Endre Sara – VP of Dev @VMTurbo

OpenStack Workload Management Challenges

• Limited workload scheduler
• Lack of real-time control
• VM placement decisions are static and

limited in intelligence

• Application and VM performance is not

assured

• Enabling OpenStack with KVM as a

viable Enterprise Private Cloud

• VMTurbo enhances OpenStack with

intelligent workload management and control

VMTurbo’s Control Platform

Guaranteeing Application Performance

DEMAND SUPPLY

VMTurbo Use-Cases

• IaaS lifecycle
• Intelligent place and control workloads by integrating VMTurbo with

the native OpenStack scheduler

• Tiered service offerings
• Guaranteeing performance of select workloads during periods of

peak utilization while increasing overall efficiency of resources

• Software license cost minimization
• Limiting workload placement to specific sockets to minimize socket-

based license costs

VMTurbo Use-Cases

• VM groups - end-user identified inter-dependencies:
• Affinity rules and Anti-affinity rules - enabling instance redundancy

for High Availability or load balancing

• "Shared nothing" live migration
• Enabling use of cheaper local storage for ephemeral backed VMs
• Preserving the ability to doVM live migration for Host maintenance,

performance or efficiency

• Host maintenance mode
• Evacuating all instances from a Host to enable
• perational maintenance of Compute nodes

VMTurbo Contribution

• Modify OpenStack (code, APIs, SDK) to discover, monitor and

control OpenStack infrastructure and workloads on par with VMware workloads

• Use the new OpenStack APIs in VMTurbo Operations

Manager

• Contribute the code to open source, so that customers may. . .
• Benefit for better OpenStack visibility and management
• Easily install VMTurbo enhancements to various versions of

OpenStack easily installing diffs from our GitHub repository

PROJECT FEATURE DESCRIPTION LINK

Ceilometer Added Disk Meters for Libvirt Storage meters per instance

Ø disk.capacity = Disk Capacity for all the disks of the instance Ø disk.usage = Disk Usage for all the disks of the instance Ø disk.allocation = Disk Allocation for all the disks of the instance

Storage Meters per disk per instance

Ø disk.device.capacity = Disk Capacity for each individual disk of an instance Ø disk.device.usage = Disk Usage for each individual disk of an instance Ø disk.device.allocation =Disk Allocation for each individual disk of an instance

Blueprint Review 145819 Specification Review Ceilometer Added VM memory metric The 'memory.resident' metric will expose the physical hosts view of the amount of host memory that is actually used to run the VM process Blueprint Review 160866 Specification Review Documentation Ceilometer PM Memory usage metric (Bug fix) Change SNMP 'hardware.memory.used' metricto reflect (memTotalReal - memAvailReal) i.e. used value for the memory for a physical machine.
