RHEL 6.4 and RHEL 5.9
for System z
This information may change until GA
16

17. Red Hat Enterprise Linux 6.4
Target beta: Dec 4, 2012
Target GA: Feb 7, 2013
17

18. RHEL 6.4 Features: Security
Support of new crypto hardware
New zcrypt module supports IBM CryptoExpress 4 cards
18

19. RHEL 6.4 Features: Security
LibICA - Crypto CP ACF
The libica library provides an interface to cryptographic hardware.
This feature adds new algorithms that support:
Message Security Assist (CP ACF) extension 4, on top of libica 2.1
For block cipher DES and 3DES, the new feature will support the following modes of
operation:
- Cipher Block Chaining with Ciphertext Stealing (CBC-CS)
For block cipher AES, this feature will support 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)
Customers require acceleration of complex cryptographic algorithms. If these
algorithms were done in software it would diminish the value of deploying on
System z, for both cost and performance reasons.
19

20. RHEL 6.4 Features: Performance
Optimized compression library zlib for Linux on 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. The expected target is about 10 % improvement, that
will improve System z price/performance for all applications that make use of
the compression library.
20

21. RHEL 6.4 Features: Performance
Kernel support to improve Java performance for Linux on System z
Provide kernel patches with support for new hardware that will improve Java
performance for Linux on System z
Improving Java performance increases Linux on System z competitiveness via
price/capacity ratio
21

22. RHEL 6.4 Features: Tools
Update to Valgrind 3.8.0
Latest System z functionality from upstream
Valgrind has proven to be a valuable tool debugging user-space
memory management problems.
Besides the capabilities to debug memory problems other plugins (cachegrind)
enable us to analyze the cache access patterns of applications which turned out
to be a key issue in order to get the best performance on z10 machines.
22

23. RHEL 6.4 Features: FCP
Implement 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
23

24. RHEL 6.4 Features: FCP
End-to-end data consistency checking
The T10 Technical Committee introduced an
enhancement to the SCSI standard (SPC-4, SBC-3) to
protect against errors in user data blocks. This
introduces the zfcp-specific part in the Linux on System
z I/O stack for E2E data consistency checking.
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
24

25. Red Hat Enterprise Linux 5.9
Beta released Sept 21, 2012
Target GA: Dec 11, 2012
Mostly bug fix release
25

26. RHEL 5.9 Features: Performance
Enable HyperPAV for parallel I/O to ECKD DASD
Licensed feature in z/VM
This item is to implement the 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
Customers will observe increased and sustained I/O performance improvements
exploiting parallel Access Volume (PAV) support for disk storage access.
Supporting HyperPAV will lead to significantly reduced configuration efforts as
opposed to static PAV setups with the system dynamically self optimizing its I/O
configuration
26

27. RHEL 5.9 Features: Performance
Kernel VDSO support
Add vdso support to speed up gettimeofday, clock_getres and clock_gettime.
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.

29. Manage the lifecycle of all Red Hat systems from x86 to
Mainframe from a centralized console.
Simplify updates, upgrades, change of configuration files, security
alerts, and more
