Which two statements are true about the types of Exadata X9M-2 storage servers: the High Capacity (HC) storage server, the Extreme Flash (EF) storage…

High Capacity (HC) Storage Server: The Exadata X9M-2 HC storage server is configured with a

combination of hard disks and flash memory, providing a balance of storage capacity and

performance.

It includes 12 x 18 TB hard disk drives, which totals 216 TB of raw disk capacity .

For flash storage, it has 4 x 6.4 TB PCIe flash cards totaling 25.6 TB of flash storage. This configuration

uses NVMe Flash Accelerator F680 cards optimized for database caching  .

The persistent memory in the HC server totals 1.5 TB, enhancing performance for OLTP (Online

Transaction Processing) workloads by providing ultra-fast access speeds compared to traditional flash

storage .

Extreme Flash (EF) Storage Server: The EF storage server in the Exadata X9M-2 model is an all-flash

storage server designed for high IOPS and low latency, making it ideal for performance-intensive

workloads.

This configuration contains 8 x 6.4 TB PCIe flash cards, providing a raw capacity of 51.2 TB of high-

performance flash storage .

In terms of persistent memory, it includes 756 GB of Intel Optane Persistent Memory. This enhances

flash storage performance by offloading data processing directly to persistent memory  .

The Exadata X9M-2 storage configurations—both HC and EF—are optimized for different workload

requirements. The HC configuration caters to larger datasets needing high storage capacity, while the

EF configuration is designed for workloads requiring high throughput and minimal latency.
