Virtualization Performance and Availability Monitoring – A Reference Architecture

In “A Perfect Storm in Availability and Performance Monitoring“, we proposed that legacy products from the physical environment should not be brought over into your new virtualized environment and that you should in fact start over with a horizontally layered approach, choosing a scaled out, and highly flexible product that can integrate with products at adjacent layers. In this post we will propose a Reference Architecture which can be used to accomplish this. Continue reading Virtualization Performance and Availability Monitoring – A Reference Architecture

Licensing VDI for Microsoft Desktops – is it rocket science?

On Feb 24, the US Space shuttle Discovery took off from Kennedy Space Centre for its final mission. At its launch, Discovery will have completed 38 voyages and traveled 230 million kilometers.  In 1970 approximately 200,000 miles from Earth in a damaged spacecraft, new protocols were  designed and new equipment re-created from spare parts in order to bring astronauts safely back to earth. In 1961 the first man entered space and come 1969, man was walking on the moon. Continue reading Licensing VDI for Microsoft Desktops – is it rocket science?

Virtualization and Cloud Conferences for the Year

It is often very hard to plan which virtualization and cloud conferences to attend and why. You may need to start your planning now as justification from work could be hard to come by. It may mean you make the decision to go on your own dime. If you do the later, there are some alternative mechanisms that could work for the bigger conferences. The conferences and events I attend every year depend on my status with the organization hosting those events, and whether or not I can get a ‘deal’ as a speaker, analyst, or blogger. So what conferences do I find worth attending? That will also depend on your job role. There is one I would attend regardless of role, and a few I would attend as a Virtualization and Cloud Security person. All are good conferences. So here is my list: Continue reading Virtualization and Cloud Conferences for the Year

VMware sends mixed message with View 4.6

Last weeks release of View 4.6 was as notable for what it included as what was absent.

When VMware first announced that it was going to license Teradici’s PCoIP protocol for inclusion in View 4.0, its most visible shortcoming was that VMware did not plan to update the View Security Server at the same time. Setting aside any debate as to the performance characteristics of PCoIP on the WAN, the lack of support for the View Security Server was a significant obstacle to widespread adoption of View in enterprise environments. So the inclusion of direct support for PCoIP tunneling through the View 4.6 Security Server comes as a most welcome update. Also included with View 4.6 are new USB enhancements, as well as support for Windows 7 SP1. Continue reading VMware sends mixed message with View 4.6

A Perfect Storm in Availability and Performance Monitoring

Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.

Getting SASy, the other shared storage option

By Greg Schulz, Server and StorageIO @storageio

Serial Attached SCSI (SAS) is better known as an interface for connecting hard disk drives (HDD) to servers and storage systems; however it is also widely used for attaching storage systems to physical as well as virtual servers. An important storage requirement for virtual machine (VM) environments with more than one physical machine (PM) server is shared storage. SAS has become a viable interconnect along with other Storage Area Network (SAN) interfaces including Fibre Channel (FC), Fibre Channel over Ethernet (FCoE) and iSCSI for block access.

Various storage options for servers include shared external DAS, networked SAN (iSCSI, FC and now SAS) or network attached storage (NAS such as NFS and Windows CIFS file sharing). In some cases, storage is moving offsite utilizing public or private clouds and managed service provided (MSP) capabilities. Also, it is important to keep in mind that DAS does not have to mean dedicated internal storage; it can also mean external shared direct accessible storage using SAS, iSCSI or Fibre Channel in a point to point topology configuration.
