Acropolis Hypervisor (AHV) is growing in features and adoption. What is most impressive is the way Nutanix is leveraging KVM (Open Source) making it very easy to use. Networking in AHV is one of the brilliant examples. In this post, I would like to throw some thoughts on Host Networking and VM Networking. Open vSwitch (OVS) is the core of the Networking in AHV. OVS functions as a Layer-2 switch which learns and maintain MAC Address table. Each AHV instance has OVS. These instances combine to form one logical switch. To state it simply if you have six node Nutanix cluster then on each node you will have OVS instance. 6 Instances of OVS combine to form a single logical Switch. So by default, it is distributed switch. New learning and therefore new terminology

I’m onboarding myself on two major technologies this year. 1) Windows 2016 and 2) Nutanix. You might have observed in the previous post I have already installed and configured ABS. So that Journey has already started. I initially hesitated but finally bought a 1 TB of SSD for T20 Dell server. By far it is not a requirement, but since AOS 5.0 is released and tons of feature it has brought it I felt, worth the AED.
As the release of AOS 5.0 has coincided With Windows 2016 released. I thought it is worth covering Windows 2016 Step-by-Step post. As a first step, you need a Windows 2016 image. Click here to download the ISO.
To upload image in AHV, login to prism portal https://clusteripaddress

In this post (Part:03) I’m covering how to configure Nutanix Acropolis Block Services (ABS). Before I start I would like to recap what was covered in Part01 and Part02.
In Part01, I covered the basics of ABS, notably new terminology, and its benefits over the previously introduced iSCSI services. I also took the opportunity to discuss in detail the use cases, especially Oracle database support.
In Part02, I discussed various considerations illustrating design considerations, especially CVM Failure scenario.
“In summary Part01 & Part02 are great to read about, but how do I actually get started fiddling around with this for myself?”
It is the main goal of this “How to post”, it is a long post. I will first configure iSCSI initiator. For iSCSI initiator, I’m using Windows 2012 R2. In case you wish to know Linux part refer official guide from Nutanix. Continue reading Nutanix acropolis block services–part03
I hope you had a chance to review Acropolis Block Services Introduction covered in Part-01 of this series. If not, please consider it as it is the foundation of Part-02 i.e. this post. In this post, I will explain pre-requisites, Terminology, and some considerations to keep in mind.
Ports 3260 and 3205 are opened between iSCSI Initiator and iSCSI Target
IP Address for iSCSI Target. By the way, Acropolis Block Services (ABS) refers this IP Address as External Data services IP Address
AOS is 4.7 & Above
iSCSI Initiator Name is also known as IQN (iSCSI Qualified Name)

In this post, My focus is on features released as part of AOS 5.0 more specifically on AHV. It must be remembered that AHV had released two years ago since then it is quickly gaining the feature parity with other hypervisors. Although AHV are on KVM yet it stands apart from other KVM version when it comes ease, support, Reliability, and performance. The Focus of AHV it to make it real for Enterprise cloud. I believe Nutanix is changing the game by completely rephrasing private cloud term into Enterprise cloud by providing AWS kind of ease, flexibility, speed and performance inside your Datacenter. In the light of upcoming AOS 5.0 release, AHV has been supplemented with various features, Acropolis Dynamic Scheduler (ADS) is one among them. It can be argued ADS feature is similar to vSphere DRS, my stand on it is little different. Regardless of whether they are same feature or function Nutanix focus is on solving contention issue instead of load balancing. The vision for ADS is simple “Resources are fully consumed without compromising end user performance.” Being a Pioneer in HCI, Nutanix is at the tremendous advantage in providing QoS service to VMs as they can measure contention at Compute and Storage level without depending on 3rd party vendor/tools/injecting drivers.

First and Foremost, Acropolis Block Services (ABS) is not new, in fact, it was always there in the form of iSCSI based block storage presented for WSFC since AOS 4.5 release. As a matter of fact, the newly released Acropolis Block Services (ABS) has more manageability and better performance which the reason it is recommended by Nutanix to use Acropolis Block Service going forward. Hold on: If you are using MPIO right now, you don’t need to worry as it won’t affect your current configuration even when upgrading to AOS4.7, but Nutanix recommends you start planning the conversion of Existing Volume groups and redirect iSCSI initiators to use ABS.

Last week I started a new blog series on weekly update around UAE/World. Though the title was ok I felt most appropriate title would be what has happened and what will happen. While it means more or less same yet I want to make the title more simple. “Happening” is the one which is scheduled to happen in an upcoming week and “has happened” is the one I missed to include in this post. And, let me point out I’m not biased against any technology if you wish to cover any of events you’re more than welcome. Continue reading What is Happening and has happened -11Dec
