Friday Spotlight: Understanding NVMe Support on Oracle Linux

Non-volatile memory express, also known as NVMe or NVM Express, is an interface specification that aims to enable a solid-state drive (SSD) to make the most effective use of the high-speed Peripheral Component Interconnect Express (PCIe) bus in a computer. 

NVMe has been supported in the mainline upstream release of Linux since kernel 3.3. Check out the commit log message for NVMe, and you can find pages of updates going back to 2011. The first distributions to support NVM Express focused on the add-in card form factor (without support for hot plug). 

Oracle was the first vendor to support NVMe hot-plug in a Linux distribution and today hot-plug is supported in all Oracle Linux releases beginning with Oracle Linux 6.4.

Oracle Linux NVMe Support *

Oracle Linux includes inbox support for NVMe SSDs beginning with Unbreakable Enterprise Kernel (UEK) Release 3 in October 2013. UEK R3 is supported in Oracle Linux 6.4 (or later) and Oracle Linux 7 (or later), and is enhanced to provide NVMe feature support consistent with mainline kernel 3.19, including hot-plug support (although without the block_mq feature).

FRIDAY SPOTLIGHT: Getting Started with Docker on Oracle Linux

Happy Friday everyone! 

We have a great technical article for you this Friday.  In this article, you learn how to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers). 

Ginny Henningsen quotes "Docker is exciting because it can easily capture a full application environment into a virtual container that can be deployed across different Linux servers. System administrators and software developers are learning that Docker can help them deploy application images on Linux quickly, reliably, and consistently—without dependency and portability problems that can inject delays into planned deployment schedules. Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud. "

As shown in Figure 1, Docker containers consume fewer resources than "heavyweight" hypervisor-based solutions. Hypervisor-based solutions host a full-blown operating system instance in each virtual machine guest, but this also allows them to support different operating systems. (Oracle VM, for example, can host Oracle Linux, Oracle Solaris, and Microsoft Windows in virtual machines.)

Whitepaper: End to End Data Integrity Using Oracle Linux, Fujitsu ETERNUS and QLogic HBA

As demand for data protection has grown in recent years, ensuring the integrity of the customer's data is a very important task. To carry out this task, data protection is not only required for the storage system but the entire system. Each system component has data protection functions such as memory parity detection, error detection with communication protocols, CRC error detection of the disk storage system, and redundancy. (Figure 1.1, I. Conventional data integrity functions) T10 PI defines the mechanism for data integrity protection that is standardized through communication paths and devices. End-to-end data integrity from applications to disk drives is implemented with the combination of T10 Protection Information (T10 PI) and Data Integrity Extensions (DIX).

This White Paper explains how data protection can be implemented for the entire system using T10 Protection Information (T10 PI) that comes with the Oracle Linux with Unbreakable Enterprise Kernel, the Fujitsu ETERNUS DX S3 series, and QLogic HBA.

Friday Spotlight: EMC PowerPath for Oracle Linux and Oracle VM Server

EMC and Oracle have a deep history of collaboration dating back to 1995. EMC is a Platinum Partner and as part of the OPN program gets pre-release access to Oracle code to test and to ensure that as Oracle and EMC products are brought to market they are proven solutions and hardened for real world use. In addition Oracle Engineering and support hold regular cadence of calls with EMC E-Lab to discuss product testing status, roadmap alignment and any open customer support issues.

EMC E-Lab has active relationships with Oracle development, one great example is PowerPath and its certification with Oracle Linux with Unbreakable Enterprise Kernel and Oracle VM. EMC PowerPath is host-based software for automated data path management, failover and recovery, and optimized load balancing. PowerPath automates, standardizes, and optimizes data paths in physical and virtual environments as well as cloud deployments to deliver high availability and performance.

EMC E-Lab helps customers adopt new technologies by leveraging their validated solutions and processes. The E-Lab Platform team runs qualification cycles against Oracle Linux and Oracle VM when the beta is released to partners for testing. This qualification work is performed against VNXe, VNX, VPLEX, VMAX, and XtremIO. The testing is performed with DM-MPIO and PowerPath. During PowerPath release cycles, Oracle and EMC qualify the new release of PowerPath against these EMC storage platforms. When new releases of EMC storage or their storage operating environment become available, it kicks off qualification cycles with the current releases of Oracle Linux and Oracle VM. The end result of this exercise is the EMC Support Matrix. Read more details in this EMC article.

EMC has also published a VMAX Engineering White Paper last week, covering Oracle VM 3.3 Storage Connect for VMAX with EMC Storage Integrator V2.0.  

We wish you Happy Holidays and the best for 2015.  We will return with Friday Spotlights on Jan 9.

Friday Spotlight: Oracle Linux and MySQL TPC-C Optimizations Whitepaper

Happy Friday Oracle Linux fans, this week our spotlight is a new whitepaper that is co- authored by Rick Stehno of Seagate and Avi Miller of Oracle. This paper gives tips to optimize your Oracle Linux, MySQL and the PCIe card which increases the performance of your environment with just few steps:

Oracle Linux and MySQL TPC-C Optimizations When Implementing the Sun Flash Accelerator F80 PCIe Card 

Oracle Linux with Unbreakable Enterprise Kernel (UEK) was chosen for this study because of its upstream support for the latest hardware relevant to modern data center operations. In addition, MySQL database workloads benefit from the platform’s deep integration with the solution stack, optimizations resulting from industry collaborations and enhancements in the Unbreakable Enterprise Kernel.

Oracle Linux with the Unbreakable Enteprise Kernel includes extensive performance and scalability improvements to the process scheduler, memory management, file systems, and the networking stack. It was tuned to perform better and faster on leading-edge x86 configurations that feature many CPU cores and large amounts of main memory, and optimized libraries and system calls help to improve performance for MySQL queries. Because of these optimizations and pervasive testing that occurs within Oracle, Oracle Linux is able to address large transaction capacities and scale well as the number of database users or the number of databases increases. This document will present tuning and processes that can be applied to increase TPC-C performance when using the Sun Flash Accelerator F80 PCIe Card.  

By following the simple tuning tips outlined in this paper, a successful implementation of the Sun Flash Accelerator F80 PCIe Card with optimal performance can occur in most environments.
