VM /ETC

A lot of companies are using NFS as the preferred protocol to shared storage for VMware Virtual Infrastructure. In my personal experience, The administrative options and convenience of NFS is unmatched, and the virtual machine (VM) performance is surprising.

For example, I recently helped migrate a company from ESX 2.X to new a installation of VI 3.5. Since the client did not have any additional space available on their fiber channel (FC) SAN for a new VMFS3 volume, we temporarily used a Windows Server 2003 R2 NFS share to host 2 dozen VMs until the existing FC volumes could be rebuilt and reconnected. The customer actually ran their production environment for 2 weeks in this configuration and was experiencing better performance. Newer hardware for the ESX hosts also contributed to this increase, but the point is that the NFS storage was not a bottleneck.

For those that are considering NFS, I was recently forwarded a list of links that provide sound arguments and testimonials on the unique advantages of using NFS with VMware. Although the published date of some of the posts that are referenced might be a bit dated, the content is still valid. Here is the list with quotes from some of the posts, but be sure to read the all in full for more information. Read the rest of this entry »

VMware announced an upcoming technology preview will be available in April for vCenter Mobile Access (vCMA). Srinivas Krishnamurti, Director of Product Management and Market Development for VMware, provided a guest post on the VMTN Blog with news about new project. Introducing VMware vCenter Mobile Access describes vCMA as a virtual appliance that will allow admins to monitor and manage their VMware virtual infrastructure from a mobile phone with what appears to be most of the same functionality available from the VI Client.

Here’s some details from Srinivas’ post about vCMA:

“Did you ever get paged when you are in a meeting about some virtual machine that needed to be restarted?  Or, did you ever get an alert when you are at your kid’s soccer game or at the movies that a particular server is overloaded?  Actually, imagine any scenario where you need to actively manage your datacenter but you are nowhere close to a PC.  Wouldn’t it be nice to act on the notification from your mobile phone?  After all, we are now a generation that doesn’t leave home without a mobile phone…

Introducing VMware vCenter Mobile Access (vCMA).  vCMA allows you to monitor and manage VMware Infrastructure from your mobile phone with an interface that is optimized for such devices. Specifically, it allows you to:

• Search for virtual machines in your data center
• Migrate virtual machines from one host to another using vMotion
• Execute recovery plans using VMware Site Recovery Manager
• Access Scheduled Tasks, Alarms and Events
• And much more…”

My recent post Why not VirtualCenter with SQL 2005 Express? explored the possible reasons for and against small and medium businesses (SMB) using the default, free database with VirtualCenter. But what happens if your virtual infrastructure implementation grows beyond 5 hosts and 50 virtual machines (VM), or what if you are close to the SQL 2005 Express database size limit of 4 GB? When it’s time to upgrade to a licensed version of SQL 2005 you can upgrade your VirtualCenter SQL 2005 Express database instance in place.

What happens when I outgrow SQL Express for Virtual Center? is a post from the VMGuy Blog by Dave Lawrence that provides the simple instructions to perform the upgrade in place. Read dave’s entire post, but here is a cut and paste of the VMGuy’s recommended upgrade steps. Read the rest of this entry »

As of VirtualCenter 2.5 (VC) MSDE was replaced by SQL 2005 Express as the default installation database. This post explores the idea of running small and medium business (SMB) VMware virtual infrastructure (VI) environments with the free SQL 2005 Express version instead of  a fully licensed instance of SQL 2005/2000.

To start with VMware’s VI3.5 and VC2.5 Installation Guide states:

The Microsoft SQL Server 2005 Express database package is installed and configured when you select Microsoft SQL Server 2005 Express as your database during VirtualCenter installation or upgrade. This is shown in Installing VMware Infrastructure Management Software. No additional configuration is required.

If Microsoft SQL Server 2005 Express is already installed, review the required database patches specified in Table 2-1. If you do not prepare your database correctly, the VirtualCenter installer might display error and warning messages.See www.microsoft.com/sql/editions/express/default.mspx.

Note: Microsoft SQL Server 2005 Express is intended to be used for small deployments of up to 5 hosts and 50 virtual machines.

5 ESX hosts and 50 VMs is definitely enough support for most small business deployments. Frankly, with modern hardware pricing the 50 VM limit will be reached before ever deploying 5 ESX hosts. 16 guests on a host is a common scenario these days which, if you do the math, creates a 3 host ESX Cluster.

So why would a company that does not expect to grow it’s number of VMs beyond 50 not use SQL 2005 Express? Here’s the 2 best reasons I could think of, and then a counter argument for each. Read the rest of this entry »

VMTN moderator and Roundtable podcast regular Jason Boche and virtualization bloggers Rick Schere and Scott Lowe are reporting that VMware will be changing the name of their flagship enterprise Virtual Infrastructure products from VI 3.5 to vSphere. Following mostly the same individuals’ tweets on Twitter I learned that the new name was decided via a vote by VMware employees. It’s unclear to me at this time when the name change will officially take place, but I imagine it will coincide with the availability of the next software release.

First some quotes from the other guys, and then my first impression.  Read the rest of this entry »

The title of this post is part of a quote from David Davis’ SearchCIO article titled COMPARISON: Microsoft vs. VMware. David’s article was published back on June 4, and it’s been sitting in my drafts “screaming at me” to comment on here at VM /ETC. Now, with Hyper-V having been released and Microsoft’s marketing machine starting to cloud virtualization reality, I point my readers to David’s arguments as examples of sane and logical analysis of the two products. Here’s the entire quote my title is taken from in the context it was written:

“VMware is obviously the most experienced company when it comes to delivering a virtualisation product. The company has 10 years of virtualisation experience and a huge customer base, including 100% of the Fortune 500 companies and 92% of the Fortune 1000, totaling over 100,000 customers worldwide. VMware also holds 11 virtualisation patents, and in 2007 their revenue hit the $US1.33 billion mark.

This is in comparison to Microsoft which has a new virtualisation product, little enterprise virtualisation experience, and, to date, no Fortune 500 customers who have adopted their enterprise virtualisation product in a production environment. Ask yourself, which of these companies sounds more qualified to deliver your enterprise virtualisation solution?”

David’s article goes on to make excellent comparison points about Read the rest of this entry »

VI3 Enterprise features VMotion, DRS, and HA require identical virtual networking settings on all of your ESX hosts. Unfortunately, VirtualCenter does not apply a central configuration policy or inheritance of settings from the cluster. Maybe a future version of VirtualCenter will evolve to include global configuration abilities? Until such a version is created, each ESX server’s virtual networking settings will continue to be configured individually by most administrators. However, there are some time saving, global configuration options available today. This post summarizes two methods provided by the virtualization community for creating PortGroups simultaneously across multiple ESX hosts. Read the rest of this entry »
