Make VirtualCenter highly available with VMware Virtual Infrastructure

Jason at has a nice write up titled: Make VirtualCenter highly available with VMware Virtual Infrastructure

A few days ago I posted some information on how to make VirtualCenter high available with Microsoft Cluster Services.

Monday Night Football kickoff is coming up but I wanted follow up quickly with another option (as suggested by Lane Leverett): Deploy the VirtualCenter Management Server (VCMS) on a Windows VM hosted on a VMware Virtual Infrastructure cluster. Why is this a good option?

This is what I plan on looking at when we purchase our own Virtual Center Licensing. ( soon )
Jason did a great job on writing this up, and thank him for it.

Zenoss Security Announcement

Matt Ray has posted a Zenoss Security Announcement on the Zenoss Blog.

Zenoss has discovered a security vulnerability related to XML-RPC authentication which, in some cases, allows for un-authenticated method invocation in all versions of Zenoss Professional, Enterprise, Service Provider and Core.

Zenoss strongly recommends you patch this vulnerability immediately. All users should review this advisory, however, those customers who have installed Zenoss in a publicly available network may be at an increased risk.

Time to upgrade!

EDIT: as said my Matt Ray

This is for for pre-2.3 releases of Zenoss only

Monitoring ESX Servers with Zenoss

Leo’s Rambling’s has a write up on Monitoring ESX Servers with Zenoss This somthing I have done, but he has done a nice write up on the process.

We all would have seen the millions of blogs lighting up with the Zenoss 3 native VI3 monitoring announcement.

Me, I wasn’t so interested – I’ve been using Zenoss for VMware monitoring for the best part of a year – it ain’t that special. Really.

I’m going to show you how to do it though, maybe it’ll be interesting…

Make sure to check out the VMware Appliances on the Zenoss download page as well.

This will allow you un- experienced Linux user the benefit of running Zenoss.

DELL Equallogic VS Fiber Channel SAN

Criag at posted a article titled : DELL Equallogic VS Fiber Channel SAN

Economy Crisis this year has encouraged users to consider the ISCSI SAN Vs FC SAN today. Data Storage growth will never stop unless the business is stop. In order to keep the environment growth, the IT architect will have to provide a cost effective solution in the finance critical timing like now.

A great read, and yet another good article on iSCSI vs FC.

I would love to hear any comments.

Setting up PowerChute Network Shutdown in VMWare ESX 3.5

Motogobi – the mobile gobi posted a article titled Setting up PowerChute Network Shutdown in VMWare ESX 3.5

I currently admin a sizable VMWare ESX deployment hosting a couple dozen domains and over a hundred Windows servers. Most are for testing and could be rebuilt pretty quickly, but some are for production deployment – at least one of which is fairly irreplaceable.

This is something I have yet to work on in full force, thanks to Motogobi for posting this.

Heads-Up: VMware ESX Going Exclusively 64-Bit

Bob Plankers at The Lone Sysadmin posted a article titled Heads-Up: VMware ESX Going Exclusively 64-Bit

There are several mentions of this out in the blogosphere, plus it was talked about openly at VMworld by VMware staff in presentations and labs. It’s worth mentioning again because people don’t seem to be catching on:

Future versions of VMware ESX/ESXi will only run on 64-bit-capable CPUs.

You will still be able to run 32-bit guest OSes, but the ESX console OS will only work on CPUs capable of Intel VT & EM64T. This is a big deal”

If you think about this, and how it would effect you and your company, I tend to agree with Bob.

We are currently running a couple ESXi Servers that are 32 bit, and even if we replaced these with 64 bit counter parts at some point, I would like to put them into a test environment or use them in a future DR site.

Let me hear your comments about this.

Hyperic HQ 4.0 Released!

Hyperic HQ 4.0 is released, and with the new features and promises, I’m going to download it right now, and give it a try.

New Capacity Planning and Application Management Features

A new capacity planning function automatically analyzes historical application and system performance and projects the future resource trends of any given management metric. This function allows users to quickly assess and predict future trends, and proactively manage capacity needs.

A new server communication design allows agents monitoring external resources to always initiate communication with the HQ Server in order to meet to security protocols and operate across firewalls. Despite the uni-directional communication, the agent still maintains a full range of capabilities including the ability to update and run diagnostics remotely, and issue corrective control actions such as a service restart or running garbage collection to free memory.

Additional Hyperic HQ 4.0 features include:

* New User Interface enhances usability and reduces the number of clicks to gain meaningful insight.
* Enterprise Dashboard portlets include a chart slideshow for key metric tracking and traffic light indicators for group availability and alerts.
* Automated agent upgrades eliminate manual agent update process.
* Script actions for alerts give users the power to automate actions based on HQ environment variables.
* Search enhancements allow users to search resources by name, group, availability and ownership.
* Downtime scheduling allow availability SLAs to take into account maintenance windows.
* JMX MBean query drills down into MBeans to review attributes and invoke operations.
* New HQ API with well documented, performant set of core operations for custom development.
* Plugin updates for Citrix XenServer, Exchange 2007, IBM MQ, VMware 3i/3.5, Zimbra 5.

It also looks to support the Amazon cloud!
