Oracle Database Appliance X5-2 Introduction
Oracle Server X5-2L is the ideal 2U platform for databases and enterprise storage solutions. Supporting the standard and enterprise editions of Oracle Database, this server delivers best-in-class database reliability in single-node configurations. With support for up to four high-bandwidth NVM Express (NVMe) flash drives, Oracle Database can be accelerated using Database Smart Flash Cache, a feature of Oracle Database. Optimized for compute, memory, I/O, and storage density simultaneously, Oracle Server X5-2L delivers extreme storage capacity at lower cost when combined with Oracle Solaris and ZFS file system compression. Each server comes with built-in, proactive fault detection, and advanced diagnostics, along with firmware that is already optimized for Oracle software, to deliver extreme reliability.
IntroductionOracle Server X52, Oracle’s latest two socket server, is the newest addition to the family of Oracle's x86 servers that are purpose built to be best for running Oracle software. The new Oracle Server X52 1U system is optimal for running Oracle Database in a clustered configuration with Oracle Real Application Clusters (Oracle RAC) and other clustered database solutions, as well as enterprise applications in virtualized environments.

Product OverviewOracle Server X5-2 supports up to two Intel® Xeon® E52600 v3 processors. Each Intel Xeon processor provides up to 18 cores, with a core frequency of up to 2.6 GHz, and has up to 45 MB L3 cache along with 24 dual inline memory module (DIMM) slots, when fully populated with twentyfour 32 GB DDR42133 DIMMs, provides 768 GB of memory. Memory bandwidth increases to 2,133 MT/sec per channel compared to 1,600 MT/sec in the previous generation.
In addition, Oracle Server X5-2 has four PCIe Gen3 slots (2 x16, 2 x8 lanes), four 10GBaseT ports, six USB ports, and eight 2.5inch drive bays providing 9.6 TB of hard disk drive (HDD) storage or 3.2 TB of solid state drive (SSD) storage. An optional DVD drive is supported to allow local access for operating system installation.
The SSD drives used in Oracle Server X5-2 are SAS-3 drives with a bandwidth of 12 Gb/sec providing double the performance of the previous generation. Oracle Server X52 can also be configured with up to four NVM Express (NVMe) drives from Oracle for a
total of 6.4 TB of high performance, high endurance PCIe flash.
Best for Oracle SoftwareOracle Server X5-2 systems are ideal x86 platforms for running Oracle software. Only Oracle provides customers with an optimized hardware and software stack that comes complete with choice of OS, virtualization software, and cloud management tools—all at no extra charge. Oracle's optimized hardware and software stack has enabled a 10x performance gain in its engineered systems and has delivered worldrecord benchmark results. Oracle's comprehensive, open standardsbased x86 systems provide the best platform on which to run Oracle software with enhanced reliability for data center environments.
In today’s connected world, vast amounts of unstructured data flow into an enterprise, creating an immediate business need to extract queriable structured data grams from this slew of information. Online transaction processing (OLTP) is a technology that historically has been used for traditional enterprise applications such as enterprise resource planning (ERP) and human capital management (HCM). Now OLTP finds itself in a unique position to accelerate business intelligence and analytics. As such, this places greater demands on the database, I/O, and main memory requirements in data centers. Oracle Database is designed to take advantage of hardware features such as high core count central processing units (CPUs), non-uniform memory access (NUMA) memory architectures, and tiered storage of data that enhance system performance.
Benefits include increased transaction throughput and improved application response
times, which reduce the overall cost per transaction.
Oracle Server X5-2, NVM Express and Oracle Database Smart Flash CacheOracle Database utilizes a feature called Database Smart Flash Cache. This feature is available on Oracle Linux and Oracle Solaris and allows customers to increase the effective size of the Oracle Database buffer cache without adding more main memory to the system. For transaction based workloads, Oracle Database blocks are normally loaded into a dedicated shared memory area in main memory called the system global area (SGA). Database Smart Flash Cache allows the database buffer cache to be expanded beyond the SGA in main memory to a second level cache on flash memory.
Oracle Server X52 introduces a new flash technology called NVM Express that provides a high bandwidth, low latency PCI Express (PCIe) interface to large amounts of flash within the system. Oracle Database with Database Smart Flash Cache and Oracle Solaris ZFS are specifically engineered to take advantage of this low latency, high bandwidth interface to flash in Oracle Server X52. Oracle Solaris and Oracle Linux are co-engineered with Oracle Server X52 to function in enterprise class workloads by enabling hot pluggable capabilities.
Traditional SSDs with a SAS/SATA interface are a popular method of adding flash to a server, and these take advantage of legacy storage controller and disk cage infrastructure. NVM Express is an entirely new end to end design that eliminates the performance bottlenecks of using conventional storage interfaces. The new NVMe flash drives in Oracle Server X52 provide a high bandwidth, low latency flash implementation that vastly improves OLTP transaction times.
Figure 1 illustrates a block diagram of a traditional SAS3 SSD connected to a server. The server PCIe root complex is connected to a PCIe/SAS controller that translates PCIe to SAS protocol to allow the server to read and write the SAS3 SSD. As NVMe SSDs already use the PCIe protocol, there is no need for the PCIe/SAS controller translation as shown in Figure 2.
Oracle’s NVMe drives have a much lower latency and higher bandwidth than standard SAS3 drives due to the fact that the drive connects directly to four lanes of the PCIe Gen3 with an aggregate bandwidth of 32 Gb/sec as opposed to 12 Gb/sec for a traditional SAS3 SSD.
Oracle Server X5-2 can be configured with up to four NVMe small form factor (SFF) SSDs that support up to 6.4 TB of flash storage. As flash technologies are temperature sensitive, most high performance flash drives will throttle down their I/O speeds as temperatures rise in order to protect the flash from damage. Oracle's NVMe SSDs, on the other hand, include multiple temperature sensors that are monitored by Oracle Server X5-2's Oracle Integrated Lights Out Manager (Oracle ILOM) service processor (SP) to ensure the drive maintains optimum operating temperature.
Oracle ILOM modulates the fan speed to ensure sufficient cooling for maximum system performance at all times. The benefits of this being that the system consistently operates at maximum performance across the full operating temperature range of the server independent of system configuration.
