Cluster on a chip.
By Roman Ivanov-Oracle on Dec 28, 2008
When someone is talking about cluster (in it's common meaning) we see the picture of big machines with a lots of cables and storage attached. But can you imagine a cluster on a chip? No cables. Cluster Interconnect is on the chip. Moreother, it can be 1U server which you can put on the back seat of your car and take it to your customer for demo. So it will be “mobile 1U cluster on a chip”.
Here is an exercise for you to build mobile 1U cluster on a chip.
Sun Cluster as it now supports guest Logical Domains.
With the latest release of Ldoms 1.1 you can get extra HA features, just to name a few closely related to this exercise:
Virtual Switch Support for Link Aggregated Interface
Virtual Disk Multipathing and Failover
Network Virtual I/O Performance Enhancement
Tip: Since you will be limited by storage then put ZFS on single drive and use it as a back end for each node system disk, also use clone feature to setup multiple nodes.
