Oracle VM virtualization on T4-4 : architecture and service catalog
By Eric Bezille on sept. 22, 2013
Last Tuesday, during the SPARC Showcase event, Jean-François Charpentier, François Napoleoni and Sébastien Flourac delivered very interesting uses cases of deployment of latest Oracle Systems at work : Oracle VM virtualization project on T4-4, intensive financial trading on T5-2 and a complete Information System migration to Oracle SuperCluster.
I will start to cover in this post the main points that Jean-François Charpentier focus on to build a consolidated T4-4 platform, effective for his Business users.
Oracle VM virtualization on T4-4 Architecture
As often, Mr Charpentier had to handle existing environment, that needed to be taken into account when building this new virtual platform. First he had to be able to provide a platform that could consolidate all the existing environments, the main driver here being :
- total memory requirement of existing asset
- multi-tenant capability to share the platform securely between several different networks
- comply to strong SLA
T4-4 was the best building block to cover them :
- memory : up to 2 TB
- multiple networks connection : up to 16x PCIe extension
- Oracle VM built-in with redundant channels capability and live migration
- Solaris binary compatibility to enable easy consolidation of existing environments
Overall Architecture Design
The deployment choice have been to setup 2x Oracle VM T4-4 clusters per sites as follow:
To cover his SLA requirements, Mr Charpentier built redundancy not only by providing multiple T4-4 nodes per Oracle VM clusters, but also at the Oracle VM itselfs. For Oracle VM, he chose to make redundant storage and network virtual access layer as display in the following 2 diagrams.
Oracle VM Virtual Mutlipathing with alternate I/O Domain
Oracle VM Virtual Network Access through IPMP
All of this virtual network layer being link to different network back-bones, thanks to the 16x PCIe extension of the T4-4, as illustrated in the following diagram.
Another option could have been to deploy Oracle Virtual Network, to enable the disk and network access with only 2x PCIe slots at the server layer.
Oracle VM on T4-4 Service Catalog
Beside the architecture choice, that needs to comply with strong SLA. The development of a service catalogue is also very key to bring the IT toward a service provider. And it is exactly what have been put in place by Jean-François Charpentier, as follow :
By putting in place this new virtual platform with its associated service catalog, Mr Charpentier was able to provide to his Business better agility thanks to easier and faster deployment. This platform has become the standard for all Solaris deployment for his business unit, and they expect to reach a 90% to 100% Solaris virtualization by 2014.
