Cisco Press' "Networking and IP Addressing Fundamentals" by Keith Barker, CCIE



Cisco Press' "Networking and IP Addressing Fundamentals" by Keith Barker, CCIE
5/5
Excellent material, a great refresher for a person interested in reverse engineering Network domain design. Looking forward to IPv6 presentation now and the impact to these fundamentals. I've been using hosts within LAN, WAN, ISP network, VPN like we all are. Its interesting to understand how routers, swtiches and hubs make this communication possible.

"Java Performance - Charlie Hunt Video Training"



 5/5

Pranaam!! A valuable sneak-peak, a concise presentation on Java 1.7 performance tuning, with all important GC tuning options. The course is good to reinforce Oracle Performance Tuning training or for professional performance tuners to get a refresher. Each Garbage Collection type is explained with examples from verbose GC logs. The explanation is more on what are GCs, the what to performance tune is specific to context and is rightly not a black & white answer for the audience.
The G1 garbage introduced since later versions of 1.6 is interesting and I'd like to more about this.

The sections are divided around 3 topics. Something tells me that part of this training is about to arrive with details on G1 garbage collector or improvements in concurrency in existing GC types.
  • JVM Overview
  • Collecting Performance Statistics
  • Understand HotSpot JVM GC Logs

"Learning VMware ESXi and vSphere 5.1 Administration" by Glen Martin




4/5

"Learning VMware ESXi and vSphere 5.1 Administration by Glen Martin"
Very good hands-on training on ESXi related administration, useful for everyone including Solution Architects and System Integration Architects apart from system administrators to understand VMware's virtualization tools. The training covered fundamental working knowledge on below areas:
You can look at topic index for more details
  • vCenter, vSphere, ESXi topology
  • ESXi installation, vCenter installation
  • Virtual Storage fundamentals
  • Virtual Network fundamentals
  • Creating a Virtual Machine
  • DRS
  • HA
  • vMotion
  • Storage vMotion
  • Performance tuning
  • vCenter Update Manager fundamentals and installation
  • VMware Update Manager
  • Data protection and security
The instructions were clear and concise. The oration  appeared to fast forwarded, limiting pauses in between all segments, leaving the audience a bit stressed. This is not a replacement for VMware documentation by any means, but is definitely a very good view for howto on VMware tools. Further reading and training is necessary if you came in researching the Performance aspects of virtualization.
