Dell Acquires EMC; VMware to Remain Independent

طبعا كلنا سمعنا امبارح عن خبر بيع EMC الى DELL وطبعا لكل المهتمين بشركة VMware فيه سؤال بيطرح نفسه علينا كلنا ......

ايه مصير VMware فى الموضوع ده ؟؟

وخصوصا ان DELL عندها بعض ال Softwares اللى بتتنافس مع بعض منتجات VMware 

على سبيل المثال وليس الحصر فيه تنافس  فى الآتى:

VRealize operations and DELL Foglighr

VMware Horizon View and DELL vWorkspace

الإجابة من VMware بخصوص ده ان VMware سوف تبقى مستقلة كشركة منتجة للبرمجيات ولن يتم دمجها فى DELL software

VMware vRealize Operations Manager Step by Step (Part-3) Sizing and requirements of the Cluster

There is a very common question will come across your mind,

What is the resources needed for my vRealize Operations Manager? how many Cluster nodes? 

Let me simplify this with straight forward Answer, It is depend !!

• how large is your environment you will monitor and analyze
• metrics you plan to collect
• number and type of resources collected
• number and type of adapters installed
• Do you have HA or no
• the duration of data retention,
• quantity of specific data points of interest, (symptoms, changes…etc.)
• and how long you need to store your data

During the wizard of the installation in Part-1 we selected the Deployment Configuration (Small) which will take resources 4 vCPUs and 16 GB RAMs, this configurations can support up to 2000 VMs

For Extra configurations use the following sizing table guide from VMware,

Notes:

• Maximum number of remote collectors (RC) certified: 50
• Maximum number of VMware vCenter adapter instances certified: 50
• Maximum number of VMware vCenter adapter instances that were tested on a single collector: 30
• Maximum number of certified concurrent users per node (regardless of node size): 4
• If you enable High Availability (HA), then the number of the nodes will be two times more than in a non HA configuration - 8 nodes is the limit. You do not need to account for any HA overhead beyond that.
• An object in this table represents a basic entity in vRealize Operations Manager that is characterized by properties and metrics that are collected from adapter data sources. Example of objects include a virtual machine, a host, a datastore for a VMware vCenter adapter, a storage switch port for a storage devices adapter, an Exchange server, a Microsoft SQL Server, a Hyper-V server, or Hyper-V virtual machine for a Hyperic adapter, and an AWS instance for a AWS adapter.
• The limitation of a collector per node: The object or metric limit of a collector is the same as the scaling limit of objects per node.  The collector process on a node will support adapter instances where the total number of resources is not more than 2,400, 5,000, and 10,000 respectively, on a small, medium, and large multi-node vRealize Operations Manager cluster.  For example, a 4-node system of medium nodes will support a total of 20,000 objects. However, if an adapter instance needs to collect 8,000 objects, a collector that runs on a medium node cannot support that as a medium node can handle only 5,000 objects.  In this situation, you can add a large remote collector or use a configuration that uses large nodes instead of small nodes.
• If the number of objects is close to the high-end limit, dependent on the monitored environment, increase the memory on the nodes.  Contact Product Support for more details.

VMware vRealize Operations Manager Step by Step (Part-2) Architecture and High Availability

 

In this post we will go through the architecture of the product, also we we will go through step by step how to configure the high availability for the vRops by creating Master Replica for the master node of the cluster,

vRealize operations Manager Design Architecture considerations and  Node Types:

• Master Node

The Master node is the initial node in your vRealize Operations Manager cluster. if we are planning to have a Single-Node Cluster so the administration and the data are on the same master node, if we are planning to have a Multi-Node Cluster which will include one Master and one or more data nodes,

• Master Replica Node

Enabling the Master Replica Node is the key of having the High availability for the vRealize Operations Manager, if we have a problem occurred with the Master node for any reason, a failover to the replica node will occur automatically,

• Data Node

Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to monitor larger environments. to perform collection and analysis. On the Larger deployments usually adapters are only installed and configured on data nodes,

• Remote Collector Node

On the large environment we might have a distributed deployment across sites, then we will need a remote collector node that can navigate firewalls and reduce bandwidth across data centers, Remote collectors only gather objects for the inventory, without storing data or performing analysis,

Now lets start our deployment of the Master Replica Node to provide the high availability, We will start with deploying another vRops OVF same as we did earlier, We will access it through web URL access,

VMware vRealize Operations Manager Step by Step (Part-1) Overview and Installation

vRealiza operations Manager (vRops) previously called vCenter Operations Manager (vCOps) is a part from the vRealize Suite,
vRealize Suite consists of the following products:

• VMware vRealize Automation Advanced or Enterprise
• VMware vRealize Operations Advanced or Enterprise
• VMware vRealize Log Insight
• VMware vRealize Business

vRealize Suite is available with two licensing models:

• Per Processor: For on premise private cloud or virtual environments
• Per OS Instance: For public cloud workloads or workloads on physical hardware

In this post I will go through how to deploy and configure vRealize Operations Manager 6.0,

VMware vCenter 6 Step by Step (Part 2) Basic Configurations

In the first post we finished the installation of the vCenter,
VMware vCenter 6 Step by Step (Part 1) Installation
We will continue in this post with the basic configurations and Hosts add and Cluster creation,
First thing we need to do is to log in to our new vCenter using Administrator Account for vSphere.Local

Here are the first look using Web client

VMware vCenter 6 Step by Step (Part 1) Installation

VMware vSphere 6 came with lots of changes and new features, but we can say that the Installation is not that different from earlier versions,
For the ESXI deployment its almost the same experience, for the vCenter we will talk in details about Installation Step by Step,
Some new enhancement in the vCenter Server Appliance (vCSA):

• Linked Mode is Supported.
• 1000 hosts and 10,000 VMs using the embedded database.

Now lets start the step by step for the vCenter 6 deployment over Windows Server 2012 with DB hosted in Microsoft SQL 2012
First you need to install 

After installing the fix we can start the vCenter installation, Select vCenter Server for Windows, Click Install

Why do we need the documentation?

 

I spent years in IT industry in most days and in most Modern companies I found that they consider the documentation a burden not a solution for their problems .

Some of the reasons I had seen to avoid Making or updating the documentation :

• understaffed and lack the Time .
• lack of well ( no one will read it ) .
• lack the intention ( if some one know what I know I will be fired ) .
• I am the only one who do it anyway why should I document I can remember everything .
