Questions

5. Elastic Configurations
Can now have fully elastic configurations
Minimum 2 database servers and 3 storage cells
Requires license of 40% of hardware, 60% can be turned off
Turn on cores 2 at a time for growth.
Can have any number of database servers between 2 and 8 servers
Can have any number of storage cells between 3 and 14 servers.
Allows to dynamic incremental growth of the Exadata. Rack
Allows for environments with storage needs are much greater then database server horsepower to access data.

6. IPv6 Support IPv6 Support Deployment Assistant Cisco Switch
Allow configuration of IPv6 in Deployment Assistant for Exadata Install/Config
Cisco Switch
Firmware minimum 15.2(3)E2 for Cisco 4948E-F switches
Auto Service Request (ASR)
Not support, will be added in future release can bridge to IPv4 network.
Oracle Enterprise Manager
Required to be on a Bridged Network so that IPv6 clients (storage servers and compute Nodes) and Infiniband switches on Admin ip4v network
dbnodeupdate
Required that the remote repositories be on ipv6 network or an ISO utilized.
Infiniband
Remains IPv4 for private network.
Platinum Support
Will remain IPv4 until Platinum Gateway update to support IPv6

7. IPv6 Support - Assistant

8. Running cellcli commands from Computer Nodes
Run cli commands for storage cells from the database compute nodes
Can disable ssh on the storage cell nodes, not sure we completely recommend do this but certainly restrict ssh requirements and users (root, cellmonitor, celladmin)
control which commands users can run by granting privileges to roles, and granting roles to users
Allow run of list griddisk but not alter griddisk
Required create users, grant privilege, grant role
CellCLI> CREATE USER myuser PASSWOD = “myuserpassord”
CellCLI> CREATE ROLE admin
CEllCLI> LIST ROLE admin ALL DETAIL
CellCLI> GRANT PRVIILEGE ALL ACTIONS ON ALL OBJECTS TO admin

9. Fixed Allocations for Databases in the Flash Cache
ALTER IORMPLAN new attribute flashcache size
Allocate a fixed amount of flashcache for a database.
Hard limit, can not use more then allocated
Not like flashcachelimit which is a soft limit

10. Oracle Exadata Storage Stats in AWR Reports
Flashcache stats from storage cells are in AWR reports
Support for columnar flashcache and keep cache
New section in AWR Report (Flash Cache Performance Summary)
Summaries for Exadata Storage Cell stats with Database stats.
** Minimum software: Oracle Database release Bundle Patch 11

11. Cell-to-cell rebalance preserves Flash Cache population
Hard Disk predictive or real failure
Data Is rebalanced out of disk with failure
When data is rebalanced to new disk to preserve data protection the flashcache cached from the disk that failed is maintained in the flashcache.
Improves performance by no longer removing the database from flashcache for a rebalance operation from a predictive or true failure allowing database(s) to continue to access data from flash during rebal and after rebal saving the read from spinning disk which can affect performance.
Works by data cache on the source cell is automatically cached on the target cell.

12. Extreme Flash (all-flash) storage option
Extreme Flash Storage Server
Oracle Exadata storage cells can exist with an all Flash Storage option
8 1.6TB PCI Flash Drives Per Storage Server
14 Extreme Flash storage servers can achieve
263 GB per second of data scan bandwidth
4.144 Million random 8K read and write I/O operations per second (IOPS)
0.25 ms Flash latency at 2 Million IOPS
For Extreme IO workloads
Scale to millions of IOPS per second

13. Extreme Flash (all-flash) storage option
Can Use on prior Exadata Configurations
Outperform all other flash storage solutions
Storage Indexes
Hybrid Columnar Compression
Offloading
Same Great redundancy Protection

14. Oracle VM Support Can now use Oracle VM on Exadata
Consolidate environments using virtual machines on Exadata
Works on X5-2, X4-2, X4-2 and X2-2 database servers
Worlds Fastest virtualized database platform
Perfect for Cloud level solutions (Database As a Service)
Dynamically expand and shrink CPU allocations
Dynamically expand and shrink memory allocations
Software can be licenses at the VM level as they are considered trusted partitions

15. The Exadata X6 – What is New or Changed that is Important to Know

16. Exadata X6 Resources
X6-2 has 2 socket 20 core processors, Intel Xeon E v4
Default still 256G of Ram expandable to 768G
X6-2 Storage Servers CPU Upgrade to 10 core Intel Xeon E v4
Storage server flash card upgrade to 3.2TB per Card * 4 card, 12.8TB total per storage server this is double the size of the 1.6TB cards in the X5.
All Flash Option gets a storage upgrade as well, the NVMe Flash Drives go from 1.6T to 3.2TB for a total capacity of 25.6TB per sever.
8x 3.2Tb NVMe PCIe 3.0 Flash cards
300 gigabytes per second of data throughput per rack
X6-8 database servers are not really changed over the X5-8 version.

17. Other Updates in Summary
Requires the latest Exadata software
Performance improvement in Storage Cell Upgrades
Confirmed that storage cell upgrade is just over an hour
VLAN Tagging now able to be configured in the OEDA (Oracle Exadata Deployment Assistant)
Storage Indexes are preserved during rebalance operations
Moves storage indexes with other data for disk predictive failure or real failure
Capacity on Demand
X6-2 minimum cores per server 14
X6-8 minimum cores per server 56
High Capacity Storage server disk now 8TB, X5 was 4TB
