Oracle Supercluster LDOM » Live Migration » Solaris Sparc

Oracle’s hardware business its engineered systems with its own Sparc processors or Intel chips. For the most part, the Engineered Systems portfolio is composed of Exa-type systems running their own storage with Infiniband switches and Intel’s processors.  Oracle has debuted a new system that blends the very best of both SPARC and the Intel -powered Exa-category systems.

Live Migration

Among the top features included in the Oracle VM Server for Solaris Sparc has to be live migration. Live migration enables you to migrate your logical domains from one physical domain while active with zero downtime.


In this stage the source machine does pre-tests on the target system to make sure that the migration will succeed.
Here a LDOM is created until the migration is complete on the target machine, which will be in bound state.

Creating Target Logical Domain (LDOM)

Here a LDOM is created on the target machine, which will be in bound state until the migration is complete.

Transport the Runtime State

The LDOM manager also transfers through the migration process to the target machine any changes to the source LDOM. The information transferred to the Hypervisor to the target machine and is recovered on source machine from Hypervisor.

Suspend the Source Domain Name

In this phase the source domain name is frozen to get a portion of time and also the rest of the state information of the source LDOM is transferred to the target machine.

Final Hand Off

In this last measure a handoff occurs to ldom manager. It happens when the ldom is migrated and resumes execution on target machine and also the source ldom is destroyed entirely.

Oracle T5 8



Oracle T5 8

Oracle is enlarging its engineered systems portfolio this week with all the start of Oracle SuperCluster SPARC T5 the new SPARC SuperCluster T5-8. The SPARC T5 chip powers the new SuperCluster that Oracle first announced in March of this year. The T5 has 8 MB of common level 3 cache and 16 SPARC v9 centers per processor.

At the time of the SPARC T5 start, Oracle also announced a SPARC T5-8 server. The SPARC T5-8 is an 8 socket system that could produce up to 128 processor cores in total. The new SPARC SuperCluster T5-8 assembles off that first server base.

An Oracle spokesperson clarified to ServerWatch that the Oracle SuperCluster T5-8 is an engineered system that provides storage, server, networking and system software in a optimized and ready-to-run solution.

In total, the machine provides 256 compute cores and 4 TB of memory from the two SPARC T5-8 compute nodes.

While the SPARC SuperCluster is powered by SPARC compute, the integrated Exadata database storage sever is powered with a set of 6-core Intel Xeon E5-2630L processors for SQL. With up to 288 TB of raw disk capacity a complete rack settings with high capacity discs can be configured when it comes to storage capacity.
