Windows 10

After about 2 months of using Windows 10, I really like it. changes to the user interface are okay, and currently I like the edge browser over previous version on IE. With anything new there can be some rough edges, and there are with Windows 10, I have had a few days that I had to just end and restart Edge, nothing major, in general its a good operating system.


This is a drive by post for me, thought I should post something, I have not in awhile,  normal life has just gotten in the way, hopefully back to a regular routine of posts soon.


windows 10 upgrade

After downloading windows 10 over slow dsl connection final using windows 10 this morning. First thoughts interface is a little clean, it seems to use alittle more memory than windows 8.1 so I will be looking for memory to upgrade laptop.

CCNA Cloud Exam 1 Section 3 topics part 2

Identify key features of Cisco UCS

  • 3.1.c B-Series
  • 3.1.d C-Series


After review datasheets for B-series and C-series servers,  they list features,  leaning for the below for a good start for  section 3 exam topics. However  these might have to be narrowed down a bit.   what I have currently is a large list  will try to narrow it down later.

B-series features

Unified fabric –  Manage blade and rack servers from the Cisco UCS 6100 or 6200 Series Fabric Interconnects using Cisco UCS Manager

Centralized management and stateless computing – ●Through Cisco UCS Manager service profiles, reduces the number of manual steps required to deploy servers in the data center, improving server policy consistency and coherency

CCNA Cloud Exam 1 Section 3 topics part 1

3.1 Identify key features of Cisco UCS
3.1.a Cisco UCS Manager
3.1.b Cisco UCS Central
Key Features Cisco UCS Manager –  Increased agility, Provide Flexibility, and Improve Visibility and Control.

Increased agility – Cisco UCS Manager supports data center automation, helping to increase operational agility and scalability, while reducing risk. It provides policy-based management with service templates and service profiles.

Provide Flexibility –  Cisco UCS Manager facilitates operation of workloads on physical as well as virtualized Cisco UCS servers. It promotes server consolidation and offers the flexibility to run workloads on blade or rack-mount servers

Improve Visibility and Control –  Integration of the Cisco UCS Manager with industry-leading systems management solutions supports the use of existing IT staff, skills, tools, and processes. A comprehensive, open XML API that exposes 9000 points of integration and facilitates custom development to achieve new levels of system visibility and control.

Cisco UCS Manager offers:

  • A unified embedded management interface that integrates server, network, and storage access
  • Policy and model-based management, with service profiles, that improves agility and reduces risk
  • Auto-discovery to detect, inventory, manage, and provision system components that are added or changed
  • A comprehensive open XML API, which facilitates integration with third-party systems management tools
  • Role-based administration that builds on existing skills and supports collaboration across disciplines


Key Features Cisco UCS Central – Simplify Operations at Scale, Increase Global Visibility and Control, Provide Flexibility.

Simplify Operations at Scale  – Cisco UCS Central software manages multiple, globally distributed Cisco UCS domains with thousands of servers from a single pane. It can simplify global policy compliance. Using SingleConnect Technology, Cisco UCS provides unified, embedded management of all software and hardware components with the Cisco UCS Manager. Every instance of Cisco UCS Manager and all of the components managed by it form a domain. Cisco UCS Central integrates with Cisco UCS Manager, and utilizes it to provide global configuration capabilities for pools, policies, and firmware.


Increase Global Visibility and Control –  Cisco UCS Central aggregates inventory and fault information across multiple Cisco UCS domains to facilitate service assurance for the Cisco UCS infrastructure. Like Cisco UCS Manager, it exposes an XML API for integration with customer and partner management solutions

Provide Flexibility  –  Cisco UCS Central software does not replace Cisco UCS Manager, which is the basic engine for server management in individual Cisco UCS domains. Unlike Cisco UCS Manager, which is embedded in the Fabric Interconnects, Cisco UCS Central is a virtual machine image that can be run on a hypervisor to provide powerful compute infrastructure management.

Cisco UCS Central can provide global definition capabilities for policies and resource pools which can be flexibly allocated across distributed data centers. This enables administrators to follow a “define once, deploy many times” workflow for their compute infrastructure.



Adding new page to Blog.

The page is going to focus on VPN commands for Cisco ASA.   version of CLI commands may be a little date, but this is what I am currently working with.  I might look at doing a few other pages like the VPN commands page.  It will go up later to day and the Cloud CCNA exam section 3 post is still in the works and should be up this weekend.

CCNA CLOUD Exam topics section 2

Understanding Cisco Cloud Fundamentals (210-451)  exam topics section 2

2.0 Cloud Deployment


2.1 Describe cloud deployment models

  • 2.1.a Public
  • 2.1.b Private
  • 2.1.c Community
  • 2.1.d Hybrid

2.2 Describe the Components of the Cisco Intercloud Solution

  • 2.2.a Describe the benefits of Cisco Intercloud
  • 2.2.b Describe Cisco Intercloud Fabric Services


Public –  The IT resources on public clouds are usually provisioned via the previously described cloud delivery models and are generally offered to cloud consumers at a cost or are commercialized via other avenues (such as advertisement).


Private –  private cloud is owned by a single organization. Private clouds enable an organization to use cloud computing technology as a means of centralizing access to IT resources by different parts, locations, or departments of the organization. When a private cloud exists as a controlled environment, the problems described in the Risks and Challenges section do not tend to apply.


Community –  A community cloud is similar to a public cloud except that its access is limited to a specific community of cloud consumers. The community cloud may be jointly owned by the community members or by a third-party cloud provider that provisions a public cloud with limited access. The member cloud consumers of the community typically share the responsibility for defining and evolving the community cloud (Figure 1).

Membership in the community does not necessarily guarantee access to or control of all the cloud’s IT resources. Parties outside the community are generally not granted access unless allowed by the community.


Hybrid  –  A hybrid cloud is a cloud environment comprised of two or more different cloud deployment models. For example, a cloud consumer may choose to deploy cloud services processing sensitive data to a private cloud and other, less sensitive cloud services to a public cloud. The result of this combination is a hybrid deployment model


Cisco Intercloud  –  Benefits

Currently trying to decide what the benefits of Cisco Intercloud  are, downloaded a PDF from Cisco product page. Lots of use case and what Intercloud is, but not really a lot of useful points for benefits.   I will have to come back and edit this section after diving more deeply into Cisco Intercloud.


Cisco Intercloud Fabric Services

Allows extension of private cloud in to public cloud while maintaining same level of security on polices across both environments.

(the above is the basic description of this in a business model and does not include from a service provider, will edit posting later.)
