I’m starting today series of posts focusing solely on backing up VMs hosted on Hyper-V. In these posts, I will cover the unique configurations of Hyper-V and Vembu BDR. There are striking differences in the configuration steps which I considered worth covering in these posts. Continue reading Configuring Vembu Backup on Hyper-V
Two weeks have passed like a flash, and I could sense things are flooding be information or for that matter work. I want to blog about Nutanix. But no time so far. I finished two posts on Nutanix Block Service here and here. I have yet to complete 3rd part. I’m hoping to finish it before next week. As I’m on Nutanix, I’m extremely glad to be considered as Nutanix Technology Champion 2017
So far I have covered how to take backup of Files, Virtual Machines, and multiple methods to protect the data. Today I will demonstrate restoration process to restore Virtual machines. Recovering data in Vembu is simplified. It is few steps I had to perform.
I noticed there are several options to restore which is seen below.
There is a growing trend in using Electronic Medical Records in all advanced hospitals. EMR has provided tremendous advantages in keep track of patient health records. As technology has advanced so is the threat to exploit this highly sensitive data has grown exponentially. Data breaches in Healthcare industry has seen steep growth. To protect highly sensitive data traditional approach is not sufficient. Defense in depth approach is essential to protect against data breaches, as each layer offer unique protection mechanism.

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. Continue reading Nutanix Acropolis Block Services – PART01
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
Do you have a home lab to practice virtualization technologies? Then you’re going to need centralized storage to make the full use of all the available features. The most optimal way to enable this is to use a storage system which can virtualize itself. Several Virtual Storage Appliances (VSA) are available and it can be tricky to decide which is the best to use. Neil Anderson (www.flackbox.com ) has published a list of all the available VSA’s including their system requirements and links to setup guides for each one. There’s also recommendations on which VSA is most suitable for you given your needs.
Last week Cyberattack was reported in Aviation Sector of Saudi Arabia. More details are available here
8th Dec VMUG in Dubai is scheduled and sponsored by Redington. Details are available here. Please do register as seats are limited, Redington has impressive Datacenter, you might get an opportunity visit it. Continue reading IT News Around UAE/World
