Below is the architecture we tested against. For information on other reference architectures see http://www.rackspace.com/cloud/private/architecture/
Nova-networking is used since Quantum is not yet included in Alamo.
When adding a Rackspace Private zone with basic networking and security groups to the RightScale Dashboard, the following cloud capabilities should be set:
Runs the Cinder, Swift-Proxy, Glance, Nova-Network. Nova-Manage, Keystone, Horizon and MySQL services. Each service will share the database on this server. Provides image management, block storage, object storage proxy and compute management. This server has high I/O and network requirements. A RAID5 array provides imporoved disk I/O while still providing fault tolerance. 10Gb network configuration is recommended for the storage server to reduce instance and snapshot creation time.
If block storage disk space becomes an issue, additional Cinder nodes can be added to increase space. Adding extra Glance servers can be used to reduce disk and network I/O on each Glance server.
Runs swift storage nodes. Provides storage space and distribution to Swift cluster.
10GB Private NIC
Additional hypervisors should be added to a cluster in the event that VMs cannot be launched due to hypervisor disk or memory capacity. Extra hypervisors can also be added to a cluster if VMs are running slow due to insufficient disk I/O.
|Component||Server||Disk Speed||Disk Size||CPU||Memory||Port Speed|
|Management||raxpmgmt1||15k SCSI||3.6TB(7x 600GB 15k SCSI - RAID5)||Single 5310||8GB||10Gb|
|Hypervisor||raxpkvm1||SSD||1.6TB (4x 400GB SSD - RAID0)||Dual X5650||48GB||10Gb|
|Hypervisor||raxpkvm2||SSD||1.6TB (4x 400GB SSD - RAID0)||Dual X5650||48GB||10Gb|
Zenoss is recommended for OpenStack monitoring, but the OpenStack monitoring script is also compatible with Nagios.
