Oracle experts. Extensive end-to-end testing and validation ensures all components includingdatabase software, operating system, firmware, drivers, etc., work seamlessly together and that thereare no performance bottlenecks or single points of failure.Because all Exadata Database Machines are identically configured, customers benefit from theexperience of thousands of other customers’ Exadata Database Machine deployments. Customermachines are also identical to the machines Oracle Support uses for problem identification andresolution, the machines Oracle Development uses for development and testing of the OracleDatabase, and the machines that run Oracle’s own public cloud services. Exadata is the mostthoroughly tested and tuned platform for running Oracle Database.Any application that uses the Oracle Database today can be seamlessly migrated to theExadata Database Machine, with no changes to the application. Likewise, any Oracle Database canalso be easily migrated off Exadata, eliminating “lock-in” concerns.EXTREME SYSTEM SCALABILITY AND GROWTH WITH ELASTIC CONFIGURATIONSThe Exadata Database Machine uses a scale-out architecture for both database servers and storageservers. As workloads grow, database CPUs, storage, and networking can be added to an ExadataDatabase Machine to scale without bottlenecks. The architecture expands from small to extremelylarge configurations to accommodate workloads of any size.A brand new high-bandwidth low-latency 100 Gb/sec RDMA over Converged Ethernet (RoCE)Network Fabric connects all the components inside an Exadata Database Machine. Specializeddatabase networking protocols deliver much lower latency and higher bandwidth than is possible withgeneric communication protocols for faster response time for OLTP operations and higherthroughput for analytic workloads. External connectivity to the Exadata Database Machine is viastandard 10 Gb/sec or 25 Gb/sec Ethernet.Exadata Database Machine is the most versatile database platform. The Exadata X8M-2Database Machine uses powerful database servers, each with two 24-core x86 processors and384 GB of memory (expandable up to 1.5 TB). Exadata also uses scale-out, intelligent storage serversavailable in two configurations – High Capacity (HC) or Extreme Flash (EF). HC Storage Servers havefour NVMe PCI Flash cards each with 6.4 TB (raw) Exadata Smart Flash Cache and twelve 14 TB7,200 RPM disks. EF Storage Servers have an all-flash configuration with eight NVMe PCI Flashdrives, each with 6.4 TB (raw) storage capacity. Exadata X8M HC and EF Storage now includepersistent memory, further boosting capacity and performance. HC and EF Servers receive twelve 128GB Intel Optane DC Persistent Memory modules as a new tier between DRAM and flash. Exadatacombines persistent memory with innovative RDMA algorithms that bypass the network and I/Ostack, eliminating expensive CPU interrupts and context switches, reducing latency by 10x,from 200µs to less than 19µs.The minimal configuration of an Exadata Database Machine consists of two database servers andthree storage servers, which can be expanded into elastic configurations adding more databaseand/or storage servers within the same rack. Elastic configurations provide a flexible and efficientmechanism to meet any size business need.In addition to expanding within a rack, multiple Exadata X8M racks can be connected using theintegrated RoCE network fabric to form even larger configurations. For example, a systemcomposed of four racks is simply four times as powerful as a single rack: it provides four times the I/Othroughput, four times the storage capacity, and four times the processing power. It can be configuredas a single system or logically partitioned for multiple databases.

Application Clusters (RAC) can dynamically add more processing power, and Automatic StorageManagement (ASM) can dynamically add more storage capacity.Related ProductsFigure 1. Elastic Scale-out to Multi-rack ExadataWhen large storage capacity is required, the Oracle Exadata X8M Storage Expansion Rack isavailable. The Exadata Storage Expansion Rack enables customers to grow the storage capacity andcorresponding bandwidth of any Exadata Database Machine. It is designed for database deploymentswith very large amounts of data, including historical or archive data, backups, documents, images,XML, JSON, and LOBs. The storage expansion rack connects to the Exadata Database Machineusing the integrated RoCE network fabric and is configured with a few simple commands, as there areno LUNs or mount points. The starting configuration of the Oracle Exadata Storage Expansion Rackconsists of four storage servers and can be expanded with additional storage servers.

RDMA (Remote Direct Memory Access) allows onecomputer to directly access data from another without Operating System or CPU involvement, for highbandwidth and low latency. The network card directly reads/writes memory with no extra copying orbuffering and very low latency. RDMA is an integral part of the Exadata high-performance architecture,and has been tuned and enhanced over the past decade, underpinning several Exadata-onlytechnologies such as Exafusion Direct-to-Wire Protocol and Smart Fusion Block Transfer. As theRoCE API infrastructure is identical to InfiniBand’s, all existing Exadata performance features areavailable on RoCE.The Exadata X8M release implements 100 Gb/sec RoCE network fabric, making the world’s fastestdatabase machine even faster. Real world database workloads running on Exadata X8M, deployedwith the new shared persistent memory accelerator, have smashed the previous benchmark of6.7M Read IOPS, set by Exadata X8, with over 16 Million Read OLTP Read IOPS (8K IOs).3DATA SHEET / Oracle Exadata Database Machine X8M-2Related ServicesThe following services areavailable from Oracle: Advanced Customer Services Oracle Premier Support forSystems Oracle Platinum Services Oracle Consulting Services Oracle University courses

NEW WITH EXADATA X8M: SHARED PERSISTENT MEMORY ACCELERATIONNew with Exadata X8M, storage servers include persistent memory (PMEM) data and commitaccelerators in front of flash cache, enabling orders of magnitude lower latency accessing remotelystored data. Persistent memory is a new silicon technology, adding a distinct storage tier ofperformance, capacity, and price between DRAM and Flash. As the persistent memory is physicallypresent on the memory bus of the storage server, reads perform at memory speed, much faster thanflash. Writes are persistent, surviving power cycles, unlike DRAM. By utilizing RDMA to accesspersistent memory remotely, Exadata Smart PMEM Cache is able to bypass the network, I/Osoftware, interrupts and context switches, achieving more than 10x lower latency than previousExadata generations, down to less than 19 microseconds. Smart Exadata System Software alsoensures data is mirrored across storage servers, which provides additional fault-tolerance. Exadata’sunique end-to-end integration between Oracle Database and Exadata Storage automatically identifiesthe hottest data blocks to store, while ensuring database, persistent memory, and flash cache do nothold the same block multiple times, increasing the efficiency across the storage tiers. Addingpersistent memory to the storage tier means the aggregate performance of this new cache tier can bedynamically used by any database on any server. This is a significant advantage over general-purposestorage architectures, which preclude sharing across servers.Another smart new Exadata System Software feature boosts log write performance. Log write latencyis critical for OLTP performance, a faster log write means faster commit times. Inversely, anyslowdown of log writes can cause the database to stall. Unique to Exadata X8M, Exadata SmartPMEM Log automatically enables the database to issue a one-way RDMA log write to persistentmemory. RDMA and persistent memory technologies allow the log write to occur withoutacknowledgement, and smart software places the write across multiple servers for resilience. Thisleads to an 8x performance increase in log writes.Security and management of this new tier are also automated. Persistent memory is configuredautomatically at installation time, with no user interaction required. Hardware monitoring is configuredout of the box. Persistent memory is only accessible to databases using database access controls,ensuring end to end security of data. Deploying persistent memory in Exadata X8M is so simple, it’stransparent.“I would recommend Exadataas a platform for performance,reliability and ease of support.Those three things mean verymuch to me in my daily life.”Richard EwaldSenior Technical ArchitectSprint“Oracle Exadata enabledseamless and rapid migrationof our cloud-based, integratedbusiness applications, requiredno major modifications, andhelped us reduce costs.
