Organizations struggle with key technology challenges supporting insights, change, and speed

Understanding Data

Digital intelligence is a primary competitive advantage

Yet 88% of all data today is unstructured and invisible to computers1

“The next wave will be all about connecting dots and correlating data to produce actionable insights.” –CIO, Retail, United States2

Keeping Pace

Superior technology delivers superior performance

Yet the pace of innovation (72%) is now the top CEO challenge, even greater than security (66%)3

“Disruptive technologies could change the fundamentals of our business” –Kazuo Hirai, CEO, Sony Corporation, Japan4

Accelerating Time-to-Market

Sustainable success is now measured in days, not weeks

Outperforming CxOs are 95% more likely to focus on being first to market4

“We’ve been charged with speeding up time-to-market, both for the products we sell and for our own internal tools.”⎯Kalev Reiljan, CIO, TeliaSonera, Finland2

Architects of the future require IT infrastructure that can do more than ‘just work’Servers and storage are no longer inanimate.

They can understand, reason, and learn.

Today, they can think.

Outthink status quo.Think IT infrastructure for thecognitive era.

AIX 7.2 Server Based Flash Caching

AIX Flash Cache Engine

Flash / SSD

AIX LPAR

SAN LUN LUN LUN

I/O APIs (File System, Device, etc.)

• Server caches SAN data in server attached storage

(SSDs, SAS attached drawer, FC connected flash, etc.)

• Cache is read-only to service application reads. Writes go straight through to the SAN back-end.

• Potential benefits are performance (more transactions, reduced response time), and/or improved scale and efficiency of SAN infrastructure via SAN off-load

• For workloads that use RAM as a cache for I/O, smaller RAM caches maybe be possible with a flash based cache

• Provides storage vendor agnostic I/O caching solution integrated into AIX• Cache is transparent to workloads and requires no application code changes• Supports virtualization features such as Live Partition Mobility

• LPM support requires VIOS 2.2.4 (Dec 2015)

• For more Information - https://ibm.biz/AIX72_Flash_Cache

AIX 7.2 Next Generation AIX Live Update Technology

• Project Requirements– Use existing maintenance model and administrative tools (NIM, geninstall)– Start with live AIX kernel replacement for i-fixes, then in future extend to SPs and TLs– Long term goal is to provide non-disruptive updates for all of AIX (kernel, commands, and Libs)

AIX 7.2 Code Removal and LPP Changes

• No support for POWER6, POWER5, or POWER4

• Additional Code Removals from AIX 7.2– NIS+– NDAF– IBM Virtual Shared Disk (rsct.vsd)– IBM Systems Director Components; pConsole– Selected old adapters – IP over FC driver– Fcparray head driver– graPhigs– Java 5– Bos.INed– Obsolete locales– Selected performance toolbox components & eclipse2.rte, including bos.perf.gtools and performance workbench GUI


AIX 7.2 – Removal of Trusted Computing Base

• Remove “Trusted Computing Base”

Rationale:–Since AIX6.1, Trusted Execution (TE) is available and it's part of base AIX. –TE is a more powerful and enhanced mechanism that overlaps some of the TCB

functionality and provides advance security policies to better control the integrity of the system.

–Some key AIX features like WPAR is not supported with TCB


AIX 7.2 – Additional changes and enhancements

• Other changes – CIFS Client – move it to the AIX Expansion Pack and provide the CIFS client with "as-is" support only. – JFS “Classic”: Remove as an install option; function would remain in AIX 7.2 and continue to be supported– Include DSO features in base OS (bos.aso) – no separate LPP on AIX 7.2

• LPPs not supported on AIX 7.2– Fast Connect– Performance Toolbox– PowerSC Trusted Surveyor not supported on AIX 7.2 as management server

• OpenSSH is being added to the Bos Install menus

• HTTPD support in NIM


AIX 7.2 bos.net.tcp.client re-packaging

Goal: Reduce the need to patch unnecessary packages

– All the new split-out packages are installed by default. – User may remove the individual (split-out) packages if no other packages require them. – Once removed, those packages will not be installed/updated during future TL or SP updates. – If customers have installp packages dependent on any of the three filesets, they will need to update the pre-req for AIX 7.2. – Full details: http://ibm.biz/aix72_bos_net_packaging

http://www.linkedin.com/redir/redirect?url=http://ibm.biz/aix72_bos_net_packaging&urlhash=fIuf&_t=tracking_anet


NIM HTTP Option for Client ‘Pull’ Installation

• Benefits of using http download access?– Communication occurs over a single http port, easy firewall management– Secure transactions use digest authentication methods (TLS v1.0/1.1/1.2)– Actions are driven from the client's end (the install target), no host access required

• How does it work?– The HTTP service is an embedded http service option in NIM.– The service is dynamic, binds to a well-known port, and exists only when resources are being remotely served.– IPv4 and IPv6 environments are supported

• What is supported?– NIM scripting customization– Fileset install, bundle install

• Limitations– No support for network boot– No support for NIM BOS installation– No support for Thin Server provisioning

CAPI (Coherent Accelerator Processor Interface) is a set of IBM innovations in hardware and software that allow an application and it’s accelerated component to share the same virtual address space.

For customers, CAPI enables performance and ease of programming:

• Application to set up data coherently in shared virtual memory and call the accelerator functional unit (AFU)

• AFU to reads and writes data from and to shared virtual memory coherently across PCIe and communicating with the application

• AFU to coherently cache data in the PSL cache for quick AFU access
