Microsoft Hyper-V vs. VMware: How far is VMware Still Ahead?

Featured

Probably four of the best virtual platform developers are VMware (vSphere), Microsoft (Hyper-V), Red Hat (KVM), and Citrix (XenServer).

While they are all comparable, each with its own set of advantages, the two who seem to cause the most ruckus are VMware and Hyper-V.

There’s a lot of talk about which is better and in what way, so let’s dive into the two a little deeper.

What Is Hyper-V? [Definition & Uses For It]

Whether you’re just beginning to look into virtualization platform options for your company, or you’re a new Hyper-V user trying to get up to speed, it can be a challenge to find all the information you need in one place. That’s why I created this guide—to give you an all-in-one resource you can bookmark and refer back to as often as you need to, so you can get up and running on Hyper-V more smoothly.

Hyper-V: How To Backup Virtual Machines

hyper-v backupIf you’re new to Hyper-V and wondering how to back up your virtual machines (VMs), there are different ways you can approach the task. But like most things—some options are better than others.

Below are the most common ways Hyper-V users attempt to preserve data on their VMs, with one caveat: Some of these methods should not be relied upon as your sole backup strategy. But they do serve a purpose, and they can be useful in the right situation.

Nutanix SCOM Management Pack – Monitor Your Nutanix Infrastructure

As a Microsoft Evangelist at Nutanix, I am always asked….”How would you monitor your Nutanix Infrastructure and can I use System Center suite. And my answer always is, “YES, with SCOM”….What is SCOM you ask?
SysCnt-OprtnsMgr_h_rgb_2 Nutanix SCOM Management Pack System Center Operations Manager (SCOM) is designed to be a monitoring tool for the datacenter. Think of a datacenter with multiple vendors representing multiple software and hardware products. Consequently, SCOM was developed to be extensible using the concept of management packs. Vendors typically develop one or more management packs for every product they want plugged into SCOM.

To facilitate these management packs, SCOM supports standard discovery and data collection mechanisms like SNMP, but also affords vendors the flexibility of native API driven data collection.  Nutanix provides management packs that support using the Microsoft System Center Operations Manager (SCOM) to monitor a Nutanix cluster.

Nutanix SCOM Management Pack

The management packs collect information about software (cluster) elements through SNMP and hardware elements through ipmiutil (Intelligent Platform Management Interface Utility) and REST API calls and then package that information for SCOM to digest. Note: The Hardware Elements Management Pack leverages the ipmiutil program to gather information from Nutanix block for Fans, Power Supply and Temperature.
SCOM01 Nutanix SCOM Management Pack

Nutanix provides two management packs:

  • Cluster Management Pack – This management pack collects information about software elements of a cluster including Controller VMs, storage pools, and containers.
  • Hardware Management Pack – This management pack collects information about hardware elements of a cluster including fans, power supplies, disks, and nodes.

Installing and configuring the management packs involves the following simple steps:

  1. Install and configure SCOM on the Windows server system (if not installed) (will blog a post soon on this topic)
  2. Uninstall existing Nutanix management packs (if present)
  3. Open the IPMI-related ports (if not open). IPMI access is required for the hardware management pack
  4. Install the Nutanix management packs
  5. Configure the management packs using the SCOM discovery and template wizards

Also, I check out this great video produced by pal @mcghem . He shows a great demo of the SCOM management pack…Kudo’s Mike….also, check out his blog.

Symon Perriman….his thoughts on Hyper-V, Security and future of Virtualization on the Nutanix .NEXT community podcast

Hey everyone…I wanted to share a very cool update (and maybe a little of hero-worship 😀 ).  Well, anyways, my job at Nutanix had another highlight recently.  As many of your know, I love reading, breathing, consuming Microsoft technology. During my consumption of education, there  number of people I follow, but there are few that stand out…and one that I spent a lot of time listening to via podcasts; Symon Perriman

Symon Perriman

Symon Perriman
He takes complex technology subjects and explains it extremely well on many levels so everyone understands..He believes in the community….all things as technologists, we can all strive to achieve.

I recently had the lucky chance to interview him for the Nutanix .Next Community Podcast.  It was great honor to interview him with my colleague\buddy @NutanixTommy as we both had different points of views.

Symon joined 5nine Software earlier this year as Vice President, Business Development & Marketing and is how I came to meet Simon as part of my job in Technical Alliances at Nutanix.

For those of you who are not familiar with 5nine Software, 5nine has a great alternative management product for Hyper-V with benefits of simplified vCenter type management without the footprint of System Center. They also are the only vendor with agentless security product via the Hyper-V extensible virtual switch. Think vShield for Hyper-V…Very cool…   😎

For those that are not familiar with Symon…a brief history…
With more than 12 years of experience in the high-tech industry, Symon is an internationally recognized expert in virtualization, high-availability, disaster recovery, data center management, and cloud technologies.

As Microsoft’s Senior Technical Evangelist and worldwide technical lead covering virtualization, infrastructure, management and cloud. He has trained millions of IT Professionals, hosted the “Edge Show” weekly webcast, holds several patents and dozens of industry certifications, and in 2013 he co-authored “Introduction to System Center 2012 R2 for IT Professionals” (Microsoft Press). He graduated from Duke University with degrees in Computer Science, Economics and Film & Digital Studies.

Enjoy the show……

Until next time, Rob…

VHD vs. VHDX: Hmm….What’s the Difference

I get asked this all the time….and here is my answer. Microsoft’s virtual hard disk format, VHDX, has some important advantages over the legacy VHD format, as this VHD vs. VHDX comparison shows.

The release of Windows Server 2012 brought many new virtualization improvements, but one that caught the eye of many IT pros was the introduction of the VHDX file format. Windows Server 2012 supports the new format but also lets Hyper-V administrators use the legacy VHD format. With two virtual hard disk formats to choose from, let’s take a minute to talk about VHD vs. VHDX.
