Shared Storage Network / Interconnect

Virtualiza@on / Container Cloud



Shared Storage Fundamentals

•  Shared storage is the top requirement for Oracle RAC. •  Block storage that is supported as shared storage for RAC by the storage vendor and the server vendor is supported for RAC. h^ps://www.slideshare.net/MarkusMichalewicz/how-‐to-‐use-‐oracle-‐rac-‐in-‐a-‐cloud-‐a-‐support-‐ques@on

•  Excep@ons prove the rule. –  Shared File System require cer@fica@on. –  Storage solu@ons may be subject to “special ruling”.

•  Currently, No 3rd Party Public Cloud supports shared storage for RAC. •  Oracle ASM and ACFS are by far the preferred storage management soluFons for Oracle RAC.

•  Cau@on: no Oracle provided tool can fully reliably check the appropriate configura@on of shared storage beforehand.

10


Network / Interconnect Fundamentals

•  The interconnect is crucial to the opera@on of Oracle RAC. –  Think of it as a RDMA access path rather than a network. –  1 GigE and redundancy should be the bare minimum. –  10 GigE and redundancy are strongly recommended.

•  Converged networks and switches are supported. Rou@ng is not. –  I.E. combining public / private network communica@on.

•  In a future release, communica@on on interconnect is planned to be secured by default. –  VLANs are a logical separa@on, not a physical one.

•  E.g. they do not protect from interference on the same physical network. – When network and storage communica@on are combined, storage communica@on should get priori@zed.

•  Cau@on: no Oracle provided tool can fully reliably check the appropriate configura@on of the interconnect beforehand.

11


Virtualiza@on / Container Fundamentals

•  Choosing a virtualiza@on solu@on or a container-‐based infrastructure is a database-‐independent decision.

• Whether an Oracle RAC database can be operated in a par@cular virtualiza@on solu@on / container is the ques@on.

• Many of them can be supported. More informa@on: h^ps://www.slideshare.net/MarkusMichalewicz/how-‐to-‐use-‐oracle-‐rac-‐in-‐a-‐cloud-‐a-‐support-‐ques@on

– OpenStack, Docker (soon & for test purposes), etc. – Oracle VM is a cer@fied virtualiza@on solu@on for Oracle RAC.

• With the excep@on of Oracle RAC in Oracle VM, there is currently no best prac@ces recommenda@on for any virtualiza@on or container-‐based solu@on from Oracle. – For containers, Oracle documenta@on is provided.

12


Cloud Fundamentals

•  Choosing a Third Party Public Cloud for Oracle RAC is mainly a licensing ques@on at this point in @me. Discussed here: h^ps://www.slideshare.net/MarkusMichalewicz/how-‐to-‐use-‐oracle-‐rac-‐in-‐a-‐cloud-‐a-‐support-‐ques@on

–  For license-‐restricted 3rd Party Public Clouds no support statements are issued.

•  For an Infrastructure Cloud (IaaS) the same rules as for virtualiza@on solu@ons / containers apply in principle. – Most IaaS / 3rd Party Public Clouds are subject to “special ruling” (see above).

•  Three Oracle RAC offerings in the Oracle Cloud:

1.  In the Oracle Cloud Infrastructure Compute Classic Service 2.  In the Oracle Cloud Infrastructure Database Service 3.  As part of the Engineered System Cloud Services

1a. Oracle’s Cloud is Faster CPU utilization analysis shows OCI spends more time doing work than the other cloud


Oracle Compute Other IaaS

This CPU utilization indicates that the other cloud is spending more time waiting to do work, which points to issues beyond the physical limitation

of the virtual CPUs, particularly since both SGAs were limited to 6 GB

We see enterprises interested in moving to Oracle Cloud for a variety of technical reasons

Companies use Oracle Cloud Infrastructure as OCI is more complete & affordable

Developing new applications, built for the cloud

Reducing the development cycle

Cloud as a backup destination

Utilizing cloud as a secondary or tertiary DR point

Hosting Applications both from on-premises and the cloud

Scaling web applications

Fail fast, gain business insights

New applications

Summary & Conclusions


•  For business and mission critical applications I would by all means recommend Oracle Real Application Clusters on Oracle Cloud Infrastructure

•  We should not forget that something works and something being supported are two totally different things - the 3rd party cloud could be "used“ by individuals for RAC testing, permitting technical feasibility, as certain testing does not require licensing

•  Conclusion 1: Oracle RAC can NOT be licensed (and consequently not be used for production workload) in 3rd party public cloud environments although such claims are published on the internet

•  Conclusion 2: Oracle RAC is times faster on the Oracle Cloud than on any other cloud environment
