vSphere SRM 6.X Install and configure – Part 6 -Failover Re-protect and failback

In the previous posts we created and tested our recovery plan. at this point we know that we are ready in case we encounter a disaster at our protected site. In this post we will initiate a failover and failback to see if what we created so far actually works. Disclosure : All my Configuration and testing are made in a lab envioremnt so make sure to read and understand VMware documentation before using any of this information in a production environment. In this post we will perform the following steps: Run the recovery plan : When we running the recovery plan, SRM will migrate all the VM in the recovery plan to the recovery site in addition SRM Will shutdown our VM's on the protected site. There are two…

vSphere SRM 6.X Install and configure – Part 5 – Creating recovery plan and testing

Replication, SRM, VCAP6 - Design

Now that we've installed SRM in our lab environment and followed the SRM configuration tasks, we need to complete the last and most important step by creating a recovery plan and testing our recovery plan. The recovery plan that we will create in this post will control every step in the recovery process. If you followed the SRM Installation and Configure series on this blog, please make sure that you have configured the protection group from part 4 of this series, and also make sure that your replication is working correctly (we only use vSphere replication at this point). Creating Recovery Plan step by step: In the SRM window click on the protected site and then click on Step 6 "Create a Recovery Plan" Create a name for your recovery…

vSphere SRM 6.X Install and configure – Part 4 – Configure Protection group

Replication, SRM, VCAP6 - Design

In the previous posts we Installed SRM in our lab environment, we paired the two sites, we configured Inventory mappings and configured placeholder datastore. In this post we will continue with the configuration by adding protection groups The idea behind protection groups is to groups VM's and make sure they failover together to the recovery site. In SRM You can use protection group for array based replication and also for vSphere replication, in my lab I only configured vSphere replication at this point so I will demonstrate protection group configuration. Note: The following link is a good read on VMware blogs for SRM protection group design considerations: https://blogs.vmware.com/vsphere/2015/05/srm-protection-group-design.html Configuring Protection Group step by step: In the SRM window click on the protected site and then click on step 5 "Create Protection…

vSphere SRM 6.X Install and configure – Part 3 – Configure Placeholder datastore

Replication, SRM, VCAP6 - Design

In the previous post we Installed SRM in our lab environment and we paired the two sites and configured Inventory mappings. In this post we will continue with the configuration, if you look at VMware configuration guide the next step is to configure placeholder datastore. We need to configure a datastore on the recovery site which SRM can store the placeholder for VM's files, this datastore doesnt have to be big to contain the entire total size of the VM's In fact placeholder VM's files are very small. I wasnt able to find actual sizing document for the placeholder datastore but i did find a discuss on VMTN: https://communities.vmware.com/thread/514420 Note: You will need to configure placeholder datastore on both sites for reverse recovery Configuring placeholder datastore step by step: In the…

vSphere SRM 6.X Install and configure – Part 2 – Configure Inventory Mappings

Replication, SRM, VCAP6 - Design

In the previous post we Installed SRM in our lab environment and we also paired the two sites. In this post we will continue with the configuration. If you look at VMware configuration guide the next step is to configure inventory mappings. With Inventory Mappings we can specify how SRM maps the VM's resources at the remote site, the idea is that you use inventory mapping to dictate where in the protected site the VM's will be placed in case of a failure, you can map compute resources, VM folders and networks. So in the following examples we are going to set the following: Resource Mapping - With resource mappings you can map resource pools, standalone host vApps and clusters, You cannot map individual hosts that are part of a…

vSphere SRM 6.X Install and configure – Part 1

Replication, SRM, VCAP6 - Design

In preparation for the design exam we need to cover vSphere replication and SRM. I decided to create a lab to demonstrate the installation and configuration of SRM. On this blog, you can find more information about replication cover in the VCP/VCAP deploy sections The following are the configuration of the two datacenters used for my SRM lab Datacenter Name: EP-L1 Prod Objective: Replication Source Configuration: Using four ESXi servers in a cluster configuration Datacenter Name: EP-Remote Objective: Replication target Configuration: using two ESXi servers in a cluster configuration Note: At this point I will not use SRA’s, I will be using vSphere native replication Prerequisite: Make sure your DNS configured correctly Make sure your NTP configured correctly on all hosts, vCenter and VM’s Make sure vSphere replication is…

VCAP – Design: VMware vSphere Distributed Switch best practice notes

Networking, NIOC, VCAP6 - Design, vDS

In this post I will share my notes about VMware vSphere Distributed Switch best practice document in preparation for the VCAP Design exam. (Document link; https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/vsphere-distributed-switch-best-practices-white-paper.pdf) Notes: The document is not updated to vSphere v6; some of the information related to v5.X only. The document includes a lot of useful information. This post is only study notes; if you are not familiar with the technologies discussed in the document please read the document first. I have chosen to cover the rack server configuration only, but the document also cover blade server configuration Design Consideration: Goals: No single point of failure Isolate traffic type Use of traffic management and optimization Component configuration: Rack server with 8 1GbE NIC’s Rack server with 2 10GbE NIC’s Physical Switch – capable of switch clustering…

Updating my lab to vSphere 6.5 – part 2

Home-Lab, vsphere65

In the previous post we discuss the upgrade process for the vCenter appliance, in this post we will continue to update the lab to vsphere6.5 by upgrading the hosts. This process can be fully automated via VUM but i will like to take the manual route. Step 1: The first step is to upload the host image to a datastore that the hosts have access to and then connect the iso as a CD to the host Step 2: boot from a the CD and choose the installer from the menu, if you do not get the installer screen, check your bios setting (you might need to change the boot order) Step 3: Click enter to start the installation Step 4: accept the license agreement Step 5 : choose the…

Updating my lab to vSphere 6.5 – part 1

Home-Lab, upgrade, vcenter, vsphere65

Since vSphere 6.5 is now GA, i decided to update my lab and provide a step by step guide for the upgrade. In this post i will discuss the vCenter appliance upgrade first and then i will create another post for upgrading the hosts in the lab. Prerequisites : Before you start the upgrade please read carefully the following KB article: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2147548 This article contain important information before you start upgrading, the article includes what products are not supported and considerations before you upgrade. In my lab i am using VUM and before I started the upgrade process i need to copy the migration-assistant directory to my VUM server and run the VMware-Migration-Assistant.exe see the following link: http://pubs.vmware.com/vsphere-65/index.jsp?topic=%2Fcom.vmware.vsphere.upgrade.doc%2FGUID-6A39008B-A78C-4632-BC55-0517205198C5.html Current version: Before we start here is the current version of the…

VCAP – Design: Storage Calculation – Part 3

Storage, VCAP6 - Design

This post is a continuation of Storage Calculation - Part 2; in this post we are going to talk about how we calculate storage throughput and datastore sizing for your design. Note: This post will show basic calculations and will not take into account caching and tiering technologies Calculating throughput: In the previous post we discussed IOPS, and now we will use the IOPS in a formula to calculate the throughput. The formula to calculate the throughput is: Throughput in MB/s = Workload IOPS * IO size / 1024 For example : A Company uses storage to archive and steam video surveillance, the I/O size for this workload is 64K and the total workload IOPS is 5000 (for all cameras) lets plug the numbers = 64k * 5000 / 1024 = 312.5 MB/s …
