4 Oracle VM Exadata now supports Oracle VM with trusted partitions Much more flexible licensing, e.g. for specific options Separation of network zones Separation of classes of database, e.g. with different service level X5-2 Server System CPU: 2 sockets, 36 cores Benchware recommendation Use database virtualization [1] instead of server virtualization Use RAC One Node to move database services between server Virtual Server 1 Virtual Server 2 Virtual Server 3 [1] Oracle Multitenant on SuperCluster T5-8: Scalability Study; An Oracle White Paper April 2014 copyright 2015 by benchware.ch slide 8

sockets, 36 cores Benchware recommendation Use database virtualization [1] instead of server virtualization Use RAC One Node to move database

5 Capacity on Demand A minimum of 40% of all server cores must be licensed Example 1/8 rack has 18 cores Minimum of 4 cores per server must be licensed X5-2 Server System Eighth Rack CPU: 2 sockets, 36 physical cores, 18 available Entry-level Exadata now available copyright 2015 by benchware.ch slide 9

7 X5-2 Server System X5-2 Server System Scale-Up versus Scale-Out Exadata provides limited scale-up features Memory capacity default 256 GByte Memory extension to 512 GByte or maximum 768 GByte CPU: 2 sockets, 36 cores Memory: GByte CPU: 2 sockets, 36 cores Memory: GByte copyright 2015 by benchware.ch slide 11

512 GByte or maximum 768 GByte CPU: 2 sockets, 36 cores Memory: 256 768 GByte

8 X4-8 Server System Scale-Up versus Scale-Out Some applications need Large scale-up server More than 2 sockets and 36 cores More than 768 GByte memory But not certified for RAC CPU: 8 sockets, 120 cores, minimum 48 cores licensed with CoD Memory: 2 6 TByte X4-8 with Oracle VM and Capacity on Demand (CoD) Minimum 48 cores per server (out of 120) There are some drawbacks with Intel E7 processors... copyright 2015 by benchware.ch slide 12

11 Flash Storage, Flash Cache and Auto-Tiering Exadata V2, X2, X3, X4 HDD with flash cache Uses auto-tiering mechanism Auto-tiering algorithms work fine in most situations - but not all situations Also true for shared storage systems Benchware recommendation EF for active OLTP data for predictable Oracle performance HC for DWH systems or inactive data Instead of auto-tiering use Oracle 12 ADO Exadata X5 Replacement for High Performance Storage Server Flash only, called Extreme Flash copyright 2015 by benchware.ch slide 15

for active OLTP data for predictable Oracle performance HC for DWH systems or inactive data Instead of auto-tiering use Oracle 12

12 Compression and Encryption Exadata versus competition Compression Hybrid Columnar Compression» Different options dependent on workload profile Part of the Exadata storage software license» USD per hdd disk» USD per flash module Some flash storage vendors offer inline deduplication, compression and encryption for free Encryption Advanced Security Option License on database server» USD per core copyright 2015 by benchware.ch slide 18
