Oracle Exadata System Software release 23.1.0 introduces support for the Oracle Exadata X10M system family.

Exadata X10M is the third generation of system hardware based on RoCE Network Fabric, and offers performance and capacity improvements throughout. Highlights include:

• Exadata X10M database servers and storage servers are equipped with AMD EPYC™ CPUs that contain substantially more CPU cores than previous Exadata systems.

  In a flexible configuration:

  • Each Exadata X10M database server contains 192 CPU cores (up from 64 previously).

  • Each Exadata X10M High Capacity (HC) or Extreme Flash (EF) storage server contains 64 CPU cores (up from 32 previously).

  • Each Exadata X10M Extended (XT) storage server contains 32 CPU cores (up from 16 previously).

  In an Eighth Rack configuration, each Exadata X10M storage server contains 32 CPU cores (up from 16 previously).

  The increased CPU resources enable Exadata X10M systems to handle more users and more CPU-intensive operations, such as data compression and data encryption.

• Each Exadata X10M High Capacity (HC) and Extreme Flash (EF) storage server contains some high-performance DDR5 DRAM reserved for Exadata RDMA Memory Cache (XRMEM cache). This new caching tier benefits workloads that require ultra-low response time, such as stock trades and IOT devices, enabling them to take advantage of RDMA to access storage server data.

  See Exadata RDMA Memory for details.

• Exadata X10M database servers move to a 2 rack-unit (RU) form factor. This server format accommodates the more powerful AMD EPYC™ CPUs, and enables each server to accommodate up to 3 TB of high-performance DDR5 DRAM (up from 2TB previously) and up to 5 network interface cards (up from 3 previously) for more flexible client connectivity. The 2 RU form factor also assists with system cooling.

• Exadata X10M EF storage servers now contain two types of flash storage devices. Each EF storage server contains:

  • 4 x 6.8 TB performance-optimized flash devices. These flash devices are the same as those in the X10M HC storage servers. They are primarily used for high-performance low-latency caching with Exadata Smart Flash Cache and Exadata Smart Flash Log.

  • 4 x 30.72 TB capacity-optimized flash devices. These flash devices, combined with the performance-optimized flash devices, increase the raw data storage capacity of EF storage servers by almost 300% while still delivering much better performance and latency than hard disk drives.

• Exadata X10M HC and XT storage servers contain 22 TB disk drives (up from 18 TB previously), which increases raw data storage capacity by 22%.
