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.

Trouble with Memory Page-Sharing

In my last post I was Exploring a Limitation of VMware DRS and I have encountered another situation that had similar symptoms but the resolution was quite different.  This problem was occurring on a VMware ESX 3.5 cluster that was specifically affecting Windows 2008 R2 64bit virtual machines that were configured with four processors and eight gigabits of RAM.  These virtual machines were taking an extreme amount of time to perform a reboot.  During the reboot ESXTOP was showing insane %RDY with spikes climbing over 200.  When the reboot would finally finish several services would have failed to start.

During the troubleshooting process, we wanted to see if there was any difference in the boot speed when we performed a cold reboot. The cold boot completed faster than a reboot but the symptoms of extremely high %RDY results were still being seen as well as services being unable to start during the boot process of the virtual machine.

Invincea wins Innovation Sandbox at RSA Conference 2011

This years Innovation Sandbox at RSA Conference was won by a little known company to virtualization and cloud security vendors, its name is Invincea. However, it makes use of virtualization to aid in security. This years finalists once more included HyTrust for the inclusion of what appears to be complete UCS support within the HyTrust Appliance, Symplified which provides a unified identity within a cloud, CipherCloud which encrypts bits of your data before uploading, but not enough encryption to mess with sort and other algorithms.  Plus other non-cloud like products: Entersect (non-repudiation in the form of PKI), Gazzang (MySQL Encryption), Incapsula (collaborative security to browsers), Pawaa (embed security metadata with files), Quaresso (secure browsing without browser/OS mods), and Silver Tail (mitigation).

Last year’s finalists also had the same reach of products but many more pure virtualization security vendors with Altor picking up the win. What is interesting about the field and indeed all of RSA Conference 2011, is that 2010 looked like a blip on the radar more than anything else. Why? Because nothing on the show floor was really about the Cloud or virtualization but it was always a ready conversation. Last year, everything was about Cloud and Virtualization but no one could define anything or tell me how their products fit except for the virtualization security vendors. The Innovation Sandbox provides a very good feel for the RSA Conference show floor. Continue reading Invincea wins Innovation Sandbox at RSA Conference 2011
