Exadata X7-2 Database Server/Storage Server Hardware Components

Oracle Exadata Database Machine consists of Oracle Database servers (Comute node), Exadata Storage Servers(commonly called as cell server), and the network components to connect to your network. 

Oracle Exadata Database Machine is available as a full rack, half rack, quarter rack or eighth rack.

Exadata X7-2 Database Machines(Compute node)Hardware components

CPU

Two Intel Xeon Platinum 8160 Processors 8160(2.1 GHz) each having 24-core.So 48 Core available in a compute node and a total of 48*8= 384 CPU Core for a Full Rack. Eighth Rack HC/EF database servers have only half the cores enabled.

RAM

384GB DRAM  by default(Dynamic random access memory)- expandable upto 1.5T (24 x 64GB) with memory expansion kit

DISK

Four 600 GB 10K RPM SAS disks, hot swappable, expandable up-to eight disks. 

FLASH

No flash in compute node.

Network

• Two QDR( Quad Data Rate) infiniBand (40 Gbps) ports (PCIe 3.0), both ports active
• Two 1 GbE/10 GbE Base-T Ethernet ports or two 10GbE/25GbE Optical Ethernet SFP28 Ports - external/Client 
• Two 10 GbE/25 GbE Optical Ethernet SFP28 Ports - For external network. The 25 GbE is new in X7-2.In X6-2 there was only 10GbE so in X7-2 we have a 150% faster Ethernet.
• One 1 GbE/10 GbE  Base-T ethernet port for Integrated Lights Out Manager (ILOM) for remote management

Infiniband has been classified into 5 catagories based upton their speed FDR, FDR-10,QDR,DDR and SDR. The QDR InfiniBand provides a 40 Gbps link. InfiniBand switches and cables to form a 40 Gb/second InfiniBand fabric for database server to Exadata Storage Server communication, and RAC internode communication.

OS

Oracle Linux 6.9 with Unbreakable Enterprise Kernel 4 or Oracle VM Server 3.4.4

Exadata Storage Server X7-2 Hardware Components

CPU

Two 10 core Intel Xeon Silver 4114 Processors (2.20GHz) - So 20 CPU core per cell server. In eighth rack only 10 core will be activated.

RAM

192 GB RAM (12 x 16 GB) 

DISK

Twelve 10 TB 7.2k rpm High Capacity (HC) SAS disks ,so each cell having 12*10=120 TB raw capacity disks. Eighth Rack HC storage servers have half the disks and flash cards removed. So in a eighth RAC HC storage server there would be only 6*10=60TB available as raw storage. There is no disks in Extrem flash(EF) storage server.

Flash

Four 6.4 TB NVMe PCIe 3.0 flash cards (for High Capacity configuration)

Eight  6.4 TB NVMe PCIe 3.0 flash card (for Extrem flash configuration)

Two 6.4 TB NVMe PCIe 3.0 flash card (for Eighth Rack)

Network

Two InfiniBand QDR (40 Gb/s) InfiniBand ports all ports active.

4 embedded Gigabit Ethernet ports

1 Ethernet port for ILOM for remote management

Software/OS

Oracle Linux 6.9 with Unbreakable Enterprise Kernel 4

Oracle Exadata Storage Server Software release 18.1.0.0.0

Note:- Eighth Rack is the minimum Exadata configuration. Eighth Rack database servers have one processor each with all cores enabled. Maximum memory supported per database server is 768GB. Eighth Rack EF storage servers have half the cores and flash drives enabled. Eighth Rack HC storage servers have half the cores enabled and half the disks and flash cards removed. The optional NIC is not available for the Eighth Rack
