Should You Own or Rent Your Infrastructure?

When you went on that trip to Honolulu last summer, how did you get around? Maybe you walked, used public transportation, or had a Hawaiian friend kind enough to lend you their extra car. But if you’re like most people, you walked into a dealership, plopped down $50,000 in cash, and bought a new car.

Kidding.

There’s no economic reason to buy a car when you only intend to use it temporarily. When you’re at home longingly planning for your return to the islands, you likely have a car that you own—one that you frequently use for your predictable, routine travel needs.

Your infrastructure is the same way, and businesses need to make smart decisions when it comes to renting or owning their infrastructure. But unique use cases and business needs necessitate one or the other—or occasionally, both. Keep reading to find out which option makes the most sense for you.

The Case for Owning

Regardless of the type of workloads your business runs, chances are, many are consistent with little variation from one day to another. For these predictable instances, it makes sense to opt for a private infrastructure model—one you can constantly and reliably use for these much-needed use cases.

But how do you decide if you should stay with privately owned infrastructure—or stick with only private infrastructure?

If the majority of your workloads are well-established with little-to-no variation one day to another, then owning your infrastructure will always make sense.

And in terms of businesses overall, more are choosing the economic advantages of sticking to an on-premises cloud architecture. In fact, a recent IDC survey found that 80% of organizations are moving applications into a private cloud. And in the next 2 years, 50% of all applications in the public cloud will be moved to on-prem.

Plus, unlike renting your infrastructure, it’s fully customizable. If you own your own home, for example, you can repaint, remodel, and redesign it to your liking. Owning an on-premises infrastructure means you’re able to build it to match your organization’s needs.

But in today’s age, it’s not always easy to predict the state of your applications, and the public cloud has its own place in your organization.

The Case for Renting

Just like renting a car for your vacation, renting a public cloud architecture is the most economic decision for elastic, burstable workloads. Plus, if you intend on only using the infrastructure for a short period of time—i.e., for only a select number of workloads—then purchasing and owning your own on-prem infrastructure doesn’t make sense.

And for applications with unpredictable resource requirements, the public cloud makes the most sense, expanding when needed to accommodate these workloads. Not to mention, many businesses rely on the public cloud for backup and disaster recovery solutions.

Plus, public infrastructure is more than just a scalable, temporary solution—it also has automated, cost-efficient services built-in. Resource sharing, single-click automation, and other features make renting an attractive choice. With fractional, pay-as-you-grow economics, on-demand resources, and zero overhead, renting is undoubtedly a smart choice for businesses requiring large, rapid scaling.

Here’s the big picture: There’s a time and place for public and private cloud. While both have their spot in IT, many organizations want to leverage the power of both. So, why settle?

All About Hybrid Cloud

For many businesses, moving out of the public cloud and into one or more dedicated on-prem clouds is the answer. Even so, many aren’t willing to give up the agility and automated services the public cloud provides, asking for a blend of both a private and public cloud. Or, put another way, you’re not always going to be home, and you’re not always (sadly) going to be in Hawaii.

That’s where hybrid cloud comes in, with 91% of organizations saying it’s their ideal IT model. By combining the fractional consumption model of public cloud with the security of an on-prem infrastructure, businesses can choose to run their workloads where it makes the most sense and seamlessly move them between clouds when needed. And rather than juggling multiple cloud environments, the hybrid model consolidates cloud management.

To put this in numbers, 75% of IT teams say they’re more efficient on a hybrid cloud, realizing 49% more business value. But how exactly do you get there?

It’s a Hyperconverged Journey

If you’re renting your infrastructure long-term, you’re likely to go well over your IT budget. But understandably, businesses aren’t willing to abandon the benefits of an agile, flexible public cloud. At the same time, relying on an on-prem cloud doesn’t necessarily enable innovation and Hyperconverged infrastructure (HCI) marries both seamlessly. By leveraging industry standard components, the overall infrastructure cost goes down. Plus, you’re able to pay-as-you-go, letting you only get what you need and add onto it as necessary. The rest? Burst out additional needs into the public cloud, so you can leverage the power of both renting and owning your infrastructure (that’s your hybrid cloud).

This means much, much less capital waste as a result of technology capital investments. Instead of buying for peak utilization and losing money during normal or low utilization, businesses can align their needs with their infrastructure more precisely.

The result is a best-of-both-worlds situation: You maintain the agility of the public cloud, available for any large-scale, unpredictable workloads, but with an incremental payment plan, you’re better equipped to stay well within your budget. Plus, you maintain the much-needed security of the infrastructure you own.

It’s not a “this or that” scenario. It’s “this and that.”

How to forcibly destroy the Nutanix cluster, Cluster destroy command failing

Thanks to visit again

There will be some instance where you really want to destroy the Nutanix cluster especially when you can’t connect each node to the network or you might not aware about the clusters IP address to access. following steps are very useful when you can’t run the cluster destroy command from CVM

with the following steps you can directly connect the Nutanix nodes and can perform the cluster destroy task:

NOTE:- MAKE SURE YOU ARE TRYING TO DESTORY CORRECT CLUSTER😝

You can use the .node_unconfigure file to forcibly destroy the cluster in such situations as follows.

  • Change to the /home/nutanix directory.
    #nutanix@cvm$ cd /home/nutanix
  • Create the .node_unconfigure file in the /home/nutanix directory.
    #nutanix@cvm$ touch .node_unconfigure
  • Restart Genesis.
    #nutanix@cvm$ genesis restart

Stopping genesis (pids [4102, 4138, 4160, 4161])

Genesis started on pids [18917

  • #nutanix@cvm$ cluster status

and the message should appear “Cluster is currently unconfigured. Please create the cluster.” This is expected and correct  At this time, login to Prism and attempt to add the cvm to the cluster. If the procedure doesn’t seem to work, make sure internal vSwitch is present(this method will not work without communication over 192.168.5.0/24 network) and make sure CVM is able to reach host over management network (CVM & HOST should be configured on the same subnet). If you are facing issues with the Foundation process on the Controller VM in question, proceed to the next steps.

Verify if the Foundation process is working. Nutanix recommends that you use both the genesis status and ps -ef commands to check the Foundation status.

nutanix@cvm$ ps -ef | grep foundation

nutanix 19291 4616 0 19:10 pts/0 00:00:00 grep foundation

You can see that the Foundation process is not working

Kill the Foundation process if it is alive.

$ genesis stop foundation

$ kill -9 PID

  • Remove the zk entries from /etc/hosts

nutanix@cvm$ vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

127.0.1.1 Nutanix-Controller-VM

127.0.0.1 NTNX-16SM65110113-A-CVM

  • Stop the zookeeper process.

nutanix@cvm$ genesis stop zookeeper

  • Verify that the .node_unconfigure file does not exist

nutanix@cvm$ rm .node_unconfigure

rm: cannot remove `.node_unconfigure’: No such file or directory

  • Verify if the cluster is destroyed or not.

nutanix@cvm$ cluster status

2016-07-11 19:13:24 CRITICAL cluster:2143 Cluster is currently unconfigured. Please           create the cluster

You can see that the cluster is destroyed.

Verify if the Foundation process is now working or not

nutanix@cvm$ genesis status

 

You can see that Foundation to create new cluster is now working

Lenovo B-300 (Brocade) Fibre Channel switch configuration- SAN Switch

In this Blogs I am sharing some handy commands to configure the Lenovo B300 SAN switch, the steps are working very well with the Lenovo B300 SAN switch but it should also work fine with other B sequences SAN switch as all others switches such as HP, IBM are from the same mother (Brocade), I often had a scenario where the client doesn’t have a full fabric license and due to which replacement of the existing switch become manual task without ISL configuration, following are the steps to prepare the Lenovo B300 switch :-

 Switch admin configuration :

  1. Change the default (10.77.77.77) Management IP address
  2. Active the license port license, note down truncation key and get the license key from the Brocade swportal
  3. Upgrade the firmware if required

Switch zone configuration :

 Run #showcfg on the existing old switch and note down all the configuration

1.Create alias

##alicreate “ESXIHOST01″,”20:00:00:24:ff:09:bf:9f; 20:01:00:1b:32:29:cb:1b”

2. Create zone

##zonecreate “zonename”, “ESXIHOST01; ESXIHOST02,

3.Create configuration

##cfgcreate “configuration name”,”zonename1;zonename2,

4.Save configuration

##cfgsave

5.Enable saved configuration

## cfgenable configurationname

Whats new with NetBackup 8.2 for Nutanix AHV

Being a NetBackup expert , I always appreciate veritas to provide deep integration of NetBackup with the compatible technology’s . NetBackup Version 8.2 is GA from date June 2019 and has added good values to setup backup for Nutanix AHV

NetBackup 8.2 introduces an enhanced experience for the recovery of Nutanix AHV VMs that are protected using the BigData policy. The Administration Console’s Backup, Archive, and Restore page or the command line options can be used to plan the complete VM recovery in a user-friendly manner.

Starting with the 8.2 version, NetBackup introduces a new policy type called Hypervisor. The Hypervisor policy type lets you protect hyper converged systems and hypervisors like Nutanix Acropolis Hypervisor (AHV) or Red Hat Virtualization (RHV) The Hypervisor policy leverages several existing NetBackup features to protect the hypervisor and the virtualization workloads.

For example, Accelerator for Hypervisor using the hypervisor change block tracking capabilities You can use the Hypervisor policy for Nutanix AHV along with accelerator support with the upcoming plug-in

Create Nutanix Phoenix ISO for foundation (AHV)/ expand existing cluster with new nodes

Nutanix has provided multiple way to do the foundation for the nodes which comes without software . these blogs Is best suitable if you already have the nutanix cluster and wanted to expand with the new nodes.

Phoenix .ISO can be created from the existing cluster , phoenix .ISO will have hypervisor information + CVM which means one setup for both the installation.

First you do SSH to one of the CVM of existing cluster the find the AOS files

nutanix@NTNX-19SM3E030323-A-CVM:172.16.10.224:~/data/installer$ ls

el7.3-release-euphrates-5.10.0.1-stable-2996345ea686184a2a1a8aadb70da003198f49fd

Run the following command to create tar file , as AOS files would be in extracted format

nutanix@NTNX-19SM3E030323-A-CVM:172.16.10.224:~/data/installer$ tar -cvzf /home/nutanix/foundation/nos/$(< /etc/nutanix/release_version).tar.gz -C ~/data/installer/ $(< /etc/nutanix/release_version) –transform=”s:^$(< /etc/nutanix/release_version)/:install/:” –show-transformed-namesel7.3-release-euphrates-5.10.0.1-stable-2996345ea686184a2a1a8aadb70da003198f49fd/

Now once you have the tar file , run the following command to create the phoenix iso files

nutanix@NTNX-19SM3E030323-A-CVM:172.16.10.224: ~/foundation/bin$ ./generate_iso phoenix –aos-package=/home/nutanix/foundation/nos/el7.3-release-euphrates-5.10.0.1-stable-2996345ea686184a2a1a8aadb70da003198f49fd.tar.gz –kvm-from-aos –temp-dir=/home/nutanix/foundation/tmp

Now the download the files from the location

nutanix@NTNX-19SM3E030323-A-CVM:172.16.10.224:~/foundation/tmp$ ls -ltrh

total 6.1G

drwxr-x—. 2 nutanix nutanix 4.0K Apr 28 17:10 sessions

-rw——-. 1 nutanix nutanix 454M Jul  8 09:37 kvm.iso

drwx——. 2 nutanix nutanix 4.0K Jul  8 09:37 garbage

-rw——-. 1 nutanix nutanix 5.7G Jul  8 09:39 phoenix-4.3.1_AOS-kvm-x86_64.iso

nutanix@NTNX-19SM3E030323-A-CVM:172.16.10.224:~/foundation/tmp$ l

Configure the IPMI ipaddress for the new nodes and boot the nodes with the Phoenix ISO

Once the foundation is done for the all the nodes , you can discover the nodes from prism to expand the cluster

Veritas (Symantec) System Recovery :- Restore Physical Server image to Virtual Machine

Thanks again to visit my Blogs , Thanks for your love and Support 😊

These might be very legacy way to do the BareMetal server restore to the virtual machine but, indeed still we do have good amount of environment where they are still running there critical business application on the physical servers because application really demand the physical hardware . keeping very good backup for the physical server required little extra efforts compare to virtual environment . now a days modern datacenters are mostly virtualized and have also started moving toward containers (Docker) and for the backup admin to backup the virtual environment is like piece of cake.

With these blogs I am trying to help the audience who’s still running their application on the physical server and using Symantec System Recovery as there backup solution (imaged based)

Steps to restore the imaged based backup to virtual machine

  • The first you need to create new virtual machine with the single hard drive and make sure the BIOS version, if the source image is UEFI you need to change the VM setting to update the BIOS version to UEFI
  • Download the SDR boot disk from the VERITAS portal and mount .ISO file to the VM and boot with the CD
  • After you booted from the CD , veritas system recovery home page will open as below

1.jpg

  • First go to the network selection and start the network service
  • If your SSR images files are some where on the network then map the network drive to browse the files
  • Open the command prompt from utilities tab and run the clean command from the windows disk part utility as below

2.jpg

  • Now again come back to the home screen and select the recover my computer3
  • Once you select the recover my computer , you will see some warning but that can be ignore as you need to manually browse the location
  • Now browse the location and select the .sv2i files
  • Now you will see the initialize disk partition structure windows, here you just need to select check box on the disk and move forward with okay button
  • Select yes if it is asking you permission to write the disk structures now ?
  • Now select the all the volumes you want to restore and make sure below option are uncheck (original disk signature and restore master boot record)4.png
  • Make sure following options are unchecked5.jpg
  • Now start the restore and reboot the computer after restore Completed.

 

Thanks for reading till the end 🙂  , Please feel free to provide your advice or any suggestion

 

Create a Nutanix Cluster without Discovery (java) Applet and without IPV6

Thanks for visiting my blogs again 😊

As you already know that in order to do the foundation (Nutanix AOS installation) for the Nutanix cluster the best available option is to download the Nutanix java applet from the Nutanix support portal and foundation the node by discovering with the applet.

Java applet required ipv6 capability enabled on the network hence you need to make sure that there is no blockage in the network for ipv6. also, CVMs should be already running on the Nutanix nodes if CVMs are not running or not available on the nodes than the cluster creation neither will work with the java applet nor with the steps which I am trying to explain in this blog.

If the CVMs are not available on the Nutanix node then you must need to use Nutanix foundation VMs which is available to download on the Nutanix support portal to do the foundation

The requirement to create a Cluster without Discovery applet:-

  1. Set the IP address manually on each host
  2. Make sure all the host has the same version of hypervisor
  3. Make sure each CVM can ping every other CVM that you want in the cluster
  4. Run the genesis status command on each CVM and make sure you only see genesis and foundation running

Steps to do foundation 

  1. Once you confirmed that you satisfy above requirement, run the following command from one of the CVM (ssh)
  2. Run this command to create the cluster (assuming these are the CVM IP addresses)

##cluster -s 192.168.85.26,192.168.85.27,192.168.85.27 –skip_discovery create

Thanks for your Time and Support
