SUSE OpenStack Cloud White PaperSGI and SUSE OpenStack Cloud Reference Architecture

This.private.cloud.instance.can.be.used.for.any.of.the.typical.use.cases,.but.the.primary.motivation.is.for.High.Performance.Computing.(HPC).customers.who.might.require.an.environment.for.investigations,.proof-of-concept.and.overflow.types.of.activi-ties.beyond.their.normal,.dedicated.HPC.resources ..The.docu-ment.discusses.key.areas.of.integrating.SGI.Rackable,.scale-out.and.specialized,.SGI.UV.scale-up.computing.hardware.with.SUSE®.OpenStack.Cloud.software.while.including.specific.infor-mation.to.leverage.the.highly.automated.nature.of.the.software ..Following.these.recommendations.and.best.practices.will.allow.an.organization.to.quickly.and.confidently.deploy.the.required.infrastructure.that.yields.a.secure,.scalable,.performant,.highly.available.private.cloud.instance.for.HPC.workloads,.whether.tar-geting.testing,.development.or.production.usage.of.the.services .

The.target.audience.is.IT.professionals.responsible.for.setting.up,.configuring,.administering.and.operating.a.private.cloud.infrastructure .

Solution OverviewWhile.public.cloud.services.have.existed.for.some.time,.a.private.cloud.enables.companies.to.take.advantage.of.the.benefits.of.cloud.computing.with.less.risk.of.data.exposure.and.more.con-trol.of.resources.because.it.is.operated.behind.the.local.corpo-rate.firewall ..Private.cloud.resources.can.be.used.across.many.groups,.delivering.access.to.IT.resources.and.abstracting.the.complex,.internal.infrastructures.from.end.users ..This.abstrac-tion.also.applies.to.development.and.information.technology.operational.professionals.(DevOps) ..It.allows.individual.virtual.machines.or.workloads.to.be.provisioned.on.demand,.subject.to.allowed.quotas,.from.predefined.templates.with.little.concern.about.the.underlying.infrastructure.or.resources ..Services,.con-sisting.of.many.workloads,.can.be.provisioned.for.use.in.min-utes.and.then.scaled.appropriately.to.meet.service.demands ..For.further.reference,.the.National.Institute.of.Standards.and.Technology’s.(NIST).Definition.of.Cloud.Computing1.describes.the.important.characteristics.of.cloud.computing .

Through.integrated,.open.source.software.frameworks.such.as.OpenStack,.enterprises.can.establish.an.Infrastructure-as-a-Service.(IaaS2).private.cloud.that.delivers.on-demand.access.to.pools.of.compute,.storage.and.networking.resources.for.use.within.their.organization,.as.shown.in.the.following.illustration:

IntroductionThis white paper is written to help an organization, already familiar with HPC concepts, create and deploy an on-premises private cloud instance contained within its own network space, using computing and storage resources under its direct control.

The.underlying.network,.compute.and.storage.resources.can.essentially.be.pre-provisioned.as.necessary.to.meet.the.overall.requirements.of.the.applications.and.services.to.be.deployed.later.in.the.cloud.instance ..Compute.resources.are.provided.via.physical.servers.by.utilizing.a.hypervisor.to.run.virtual.ma-chine.workloads ..Providing.storage.resources.is.accomplished.via.distributed,.resilient.file.systems.across.industry-standard.hardware.with.local.storage.devices ..Networking.provides.the.unifying.connectivity.that.ties.the.compute,.storage.and.man-agement.elements.of.the.private.cloud.together ..Finally,.the.private.cloud.software.provides.the.user.interface.for.setup,.configuration.and.maintenance,.as.well.as.the.long-term.opera-tion.of.the.cloud.by.bonding.these.three.core.components.into.a.cohesive.service.offering .

The.remainder.of.this.white.paper.will.present.a.complete,.ready-to-use.private.cloud.solution ..The.focus.is.to.create.a.starter.cloud.instance,.using.minimal.nodes.yet.with.all.the.fea-tures.included.to.effectively.scale.as.the.usage.grows.over.time ..First,.it.will.discuss.preparations.and.considerations.across.the.various.infrastructure.elements.common.to.the.overall.solution ..Then.it.will.detail.the.steps.required.for.private.cloud.integration,.starting.with.the.setup.of.the.control.plane.and.followed.by.the.storage.and.compute.resources,.along.with.some.easy.ways.to.validate.the.installation.and.functionality.of.all.the.components .

Preparation

FACILITY CONSIDERATIONS

The.heating,.ventilation,.air.conditioning.(HVAC).and.power.re-quirements.for.a.private.cloud.deployment.need.to.be.carefully.

assessed ..As.a.reminder,.ensure.that.calculated.power.consump-tion.and.cooling.take.into.account.the.requirements.of.a.fully.utilized.infrastructure.since.a.private.cloud.instance.is.a.shared.resource.subject.to.the.needs.and.use.of.potentially.many.work-loads.and.users.at.any.given.time ..During.the.project.quoting.process,.resources.from.the.SGI.Site.Planning.team.can.provide.power.and.cooling.specifications.and.requirements.specific.to.the.systems.being.deployed .

NETWORK CONSIDERATIONS

Networking.is.the.technology.component.likely.to.take.the.most.upfront.planning.because.networking.requirements.for.a.pri-vate.cloud.instance.have.a.fair.amount.of.complexity,.especially.when.it.is.being.integrated.into.an.existing.IT.infrastructure.and.network.topology ..This.white.paper.provides.specific.recom-mendations.for.the.networking.topology.often.used.in.HPC.environments.and.equipment.that.meet.both.scale.and.perfor-mance.requirements,.with.later.sections.describing.the.specific.network.subnets.and.virtual.LAN.designations.needed.to.satisfy.the.design.decisions .

For.the.physical.switching.layer,.a.single.48.port.top-of-rack.(ToR).1GbE.switch.is.utilized.for.the.bonded.interfaces.with.separate.1GbE.switches.for.the.BMC.and.for.the.storage.networks,.since.all.the.systems.platforms.have.1GbE.network.interfaces ..Certainly.this.can.be.made.more.redundant.by.adding.a.peer.switch,.be-cause.the.networking.mode.for.the.majority.of.the.subnets.are.bonded.across.multiple.interfaces ..As.usage.grows,.both.the.sys-tem.network.interfaces.and.switches.can.be.upgraded.to.faster.interconnect.speeds ..The.basic.network.topology.is.shown.in.Figure.2.on.the.following.page .

At.this.point,.it.is.instructive.to.introduce.the.necessary.network.name.spaces.for.this.private.cloud.instance ..The.name.spaces.and.the.functions.they.provide.are.fundamental.to.a.private.cloud.im-plementation ..The.various.network.ranges.are.needed.to.manage,.operate,.access.and.provide.isolation.for.all.the.components.and.services ..Table.1.summarizes.the.various.network.name.spaces.used.in.this.implementation .

COMPUTING AND STORAGE PLATFORM CONSIDERATIONS

One.of.the.benefits.of.a.private.cloud.implementation.is.that.SGI.Rackable,.scale-out.servers.can.fulfill.many.of.the.needs.for.various.roles ..To.reduce.the.time.spent.on.hardware.specification.for.an.initial.private.cloud.implementation,.this.hardware.set.can.be.very.general.purpose.and.allow.for.a.wide.range.of.configura-tion.options.yet.still.meet.the.demands.of.the.intended.usage .

The.SGI.C2112-4RP43.series.of.servers.deliver.top.value.and.per-formance.with.four.independent.nodes.in.a.single.2U.chassis.and.up.to.12.hard.disk.drives ..In.this.configuration,.each.node.can.fulfill.any.of.the.roles.in.the.private.cloud.instance .

SUSE OpenStack Cloud Control NodesA.SUSE.OpenStack.Cloud.Control.Node.is.managed.and.de-ployed.through.the.SUSE.OpenStack.Cloud.Administration.Server.web.interface ..To.ensure.the.high.availability.of.the.control.plane,.you.need.to.create.a.cluster.of.dedicated.Control.Nodes.with.at.least.one.pair.of.nodes.needed.for.a.cluster ..An.odd.number.of.cluster.member.nodes.is.preferred.to.establish.and.maintain.a.quorum ..Multiple.clusters.are.allowed,.should.services.need.to.be.isolated.for.performance.or.other.considerations,.

such.as.whether.the.service.is.stateful.or.can.be.used.only.in.an.active-passive.mode .

Design Decisions:

The.stateful.services.for.the.Database.and.Message.Queue.will.be.deployed.on.a.pair.of.nodes.and.then.later.assigned.to.those.roles ..Combine.two.resource.nodes.(data1,.data2).into.an.HA.cluster.configuration.("data").for.these.services.via.the.Pacemaker.barclamp .

Combine.three.resource.nodes.(control1,.control2,.control3).into.an.HA.cluster.configuration.("control").for.the.remaining.control.services.via.the.Pacemaker.barclamp ..This.cluster.can.then.be.as-signed.to.many.of.the.remaining.controller.OpenStack.services .
