Oracle Exadata Storage Expansion Rack X9M-2 includes the following components:

  • Storage: Between 4 and 19 Exadata Storage Servers X9M-2.

    A base Oracle Exadata Storage Expansion Rack contains 4 High Capacity (HC) or 4 Extreme Flash (EF) storage servers. For a HC base rack, additional HC or Extended (XT) storage servers may be added to a total of 19 storage servers. For an EF base rack, additional EF or XT storage servers may be added to a total of 19 storage servers.

    Raw storage capacity:

    • With HC storage servers:
      • 4 HC storage servers: 864 TB of raw disk capacity and 102.4 TB of raw flash capacity.
      • 19 HC storage servers: 4104 TB of raw disk capacity and 486.4 TB of raw flash capacity.
    • With EF storage servers:
      • 4 EF storage servers: 204.8 TB of raw flash capacity.
      • 19 EF storage servers: 972.8 TB of raw flash capacity.
    • With XT storage servers: up to 3240 TB of raw disk capacity, in addition to either 4 HC or 4 EF storage servers.

  • RDMA Network Fabric: 3 x RoCE Network Fabric Switches

  • Power Distribution Units (PDUs): 2 x 15 kVA (single phase or three phase, high voltage or low voltage)

  • Network Connectivity: 1 x Management Network Switch

Note:

In the list above, raw capacity is expressed using standard disk drive terminology, with 1 TB = 1,000,000,000,000 bytes. Usable capacity is less.
