9 Red Hat Enterprise Linux High Level Roadmap Red Hat extended from 7 to 10 years standard technical support for RHEL 5 and RHEL End of Life: February 29, x EOF: x EOF: 2020 RHEL More than 10 years of collaboration between Red Hat and IBM. Both companies actively working together to offer mission critical Linux solution for IBM System z. 7.0 under development 9

10 Red Hat Enterprise Linux 6.4 GA: Feb New features for System z General New Features Bugfixes 10

11 Support of new crypto hardware This feature provides support for new crypto hardware: CryptoExpress4 The z90crypt device driver has been updated to support the new Crypto Express 4 (CEX4) adapter card. Data Routing for FCP Enable FCP to pass data directly from memory to SAN (data routing) when memory on the adapter card is blocked by large and slow I/O requests. Improved performance by increasing the I/O rate and throughput for short and fast I/O requests when memory on the adapter is blocked by large and slow I/O requests will satisfy customer expectations regarding performance The zfcp device driver has been updated to add data structures and error handling to support the enhanced mode of the System z Fibre Channel Protocol (FCP) adapter card. In this mode, the adapter passes data directly from memory to the SAN (data routing) when memory on the adapter card is blocked by large and slow I/O requests. 11

12 Fibre Channel Protocol End-To-End data consistency checking Data integrity between a host adapter and a storage server has been improved implementing the zfcp-specific part of The T10 Technical Committee introduced an enhancement to the SCSI standard (SPC-4, SBC-3) to protect against errors in user data blocks. This RAS item provides improved service and control of data flow between adapter and storage device by introducing the zfcp specific part of the enhanced SCSI standard for E2E data consistency checking Optimization of, and Support for, the zlib Compression Library for System z Optimize the existing compression library zlib for System z by using dedicated SSE instructions and optimized compile options. The compression library zlib is used by Java (decompression of class files), Cognos (PDF generation), TSM (backup) and for Linux installations (binaries compressed in RPMs) This feature significantly improves performance for applications using the compression library zlib. 12

13 libica Enhancements The libica library has been modified to allow usage of new algorithms that support the Message Security Assist Extension 4 instructions in the Central Processor Assist for Cryptographic Function (CPACF) feature. For the DES and 3DES block ciphers, the new feature supports the following modes of operation: Cipher Block Chaining with Ciphertext Stealing (CBC-CS) Cipher-based Message Authentication Code (CMAC) For the AES block cipher, this feature supports the following modes of operation: Cipher Block Chaining with Ciphertext Stealing (CBC-CS) Counter with Cipher Block Chaining Message Authentication Code (CCM) Galois/Counter (GCM) With this acceleration of complex cryptographic algorithms, performance of IBM System z machines significantly improves. All users of libica are advised to upgrade to these updated packages, which add this enhancement. The libica library contains a set of functions and utilities for accessing the IBM eserver Cryptographic Accelerator (ICA) hardware on IBM System z. 13

14 Storage Drivers The Direct Access Storage Devices (DASD) device driver has been updated to detect path configuration errors that cannot be detected by hardware or microcode. Upon successful detection, the device driver does not use such paths. With this feature, for example, the DASD device driver detects paths that are assigned to a specific subchannel but lead to different storage servers. Flash Express Support for IBM System z Storage-Class Memory (SCM) for IBM System z is a class of data storage devices that combine properties of both storage and memory. SCM for System z now supports Flash Express memory. SCM increments can be accessed through Extended Asynchronous Data Mover (EADM) subchannels. Each increment is represented by a block device. This feature improves the paging rate and access performance for temporary storage, for example for data warehousing. 14

15 Support of the Transactional Execution Facility Support of the Transactional-Execution Facility (available with IBM zenterprise EC12) in the Linux kernel helps eliminate software locking overhead that can impact performance and offer increased scalability and parallelism to drive higher transaction throughput. Support of Runtime Instrumentation Facility Support of the Runtime Instrumentation Facility (available with IBM zenterprise EC12) provides an advanced mechanism to profile program code for improved analysis and optimization of the code generated by the new IBM JVM. kdump and kexec Kernel Dumping Mechanism for IBM System z Fully Supported The kdump/kexec kernel dumping mechanism is enabled for IBM System z systems as a fully supported feature, in addition to the IBM System z stand-alone and hypervisor dumping mechanism. The auto-reserve threshold is set at 4 GB; therefore, any IBM System z system with more than 4 GB of memory has the kdump/kexec mechanism enabled. Sufficient memory must be available because kdump reserves approximately 128 MB by default. This is especially important when performing an upgrade to Red Hat Enterprise Linux 6.4. Sufficient disk space must also be available for storing the dump in case of a system crash. 15

16 Enhancements to the s390-tools BZ# This update adds the necessary user space tools to allow Linux to access Storage Class Memory (SCM) as a block device on IBM System z systems using sub-channels of the Extended Asynchronous Data Mover (EADM) Facility. BZ# The lszcrypt utility has been modified to support the IBM Crypto Express 4 feature. 16

17 Red Hat Enterprise Linux 5.9 GA: Dec Mostly Bugfix release One big feature for System z Enable HyperPAV for parallel I/O to ECKD DASD 17

18 Hyper PAV enablement - Licensed feature in z/vm HyperPAV enables parallel I/O to ECKD DASDs increasing data access performance Hyper-Parallel-Access-Volume support for Linux on System z. This is a very flexible concept to massively improve device performance by using a set of sub channels as an ALIAS-pool. Kernel VDSO Support Virtual Dynamically-linked Shared Object (VDSO) is a shared library provided by the kernel. This allows normal programs to do certain system calls without the usual overhead of system calls like switching address spaces. For Linux on System z there are tree functions at the moment that are accelerated in this way: gettimeofday, clock_getres, and clock_gettime. The most important one is probably gettimeofday. Some user space application, for example the Java virtual machine, tend to call gettimeofday very often. By use of a vdso this operation can be accelerated by an factor of 4 thereby increasing the performance of the user space application. 18

19 JAVA 7 Due to EOL of Oracle JDK6 in November, Oracle Java 7 and IBM counterpart will be available to Red Hat Enterprise Linux 5 19
