Well, that’s what I kept telling myself during the class. Talk about a lot of stuff to remember! Lots of great info by our instructor, Micheal Link. Hopefully enough of it stuck. With any luck I’ll have the Foundations cert early next week!
Replacing the default SSL cert on vCenter 4.1u1
vCenter 4.1 includes a self-signed SSL certificate upon installation. In some situations, especially in larger environments with an existing PKI infrastructure, you may need to replace this with a valid SSL certificate for your environment. VMware published a document (linked below) on doing this, however it can be a little confusing and I had to [...]
vSphere 4.1 HA Overview
The High Availability (HA) feature in vSphere 4.1 allows a group of ESX/ESXi hosts in a cluster to identify individual host failures and thereby provide for higher availability of hosted VMs. HA will restart VMs which were running on a failed host; it is a high-availability solution, not a zero-downtime solution such as application clustering [...]
Attended the DC VMware vCenter Operations Seminar.
I was lucky enough to catch this seminar in DC last week, it was full of great info. Operations looks like a great product and the demo was pretty interesting, I’m itching to get my hands on it and play with it in my lab. Everyone loves monitoring and config management, the ability to integrate [...]
Exchange 2010 SP1 now supports HA/DRS/vMotion
Microsoft recently updated their Exchange Hardware Virtualization Requirements for Exchange 2010 SP1 to specifically support HA, DRS and vMotion/Live Migration. This is a fairly significant change since prior to this being supported a virtualized Exchange 2010 environment had to be carefully planned to disallow HA/DRS and vMotion on specific VMs and this greatly simplifies standing [...]
Good Reads: vSphere Networking Performance Whitepaper
VMware recently released this whitepaper which graphs out networking performance under vSphere with simulated loads and in multiple configurations. It’s interesting to see that a single-CPU VM can saturate a 10GbE link, and a 4-CPU VM with 4-uplinks can easily saturate four 10GbE links… vSphere scales very well compared to ESX 3.5. http://www.vmware.com/files/pdf/techpaper/Performance-Networking-vSphere4-1-WP.pdf
I’m certifiable!
I received the email from ISC2 I’ve been anxiously awaiting for about the last month after submitting my CISSP endorsement package, it began with “Congratulations!” and ended with me jumping about 4 feet in the air. I’m not sure if the exam or the waiting was worse, but I’m happy to have obtained the CISSP [...]
